Below is general information about the safety of the known ingredients contained in the product Test 1700. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Ashwagandha has been used with apparent safety in doses of up to 1250 mg daily for up to 6 months (3710,11301,19271,90649,90652,90653,97292,101816,102682,102683) (102684,102685,102687,103476,105824,109586,109588,109589,109590). ...when used topically. Ashwagandha lotion has been used with apparent safety in concentrations up to 8% for up to 2 months (111538).
PREGNANCY: LIKELY UNSAFE
when used orally.
Ashwagandha has abortifacient effects (12).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. There are no reports of significant toxicity in multiple human trials (4901,4903,4904,4905,4906,4907,4908,4909,36980,36988) (36992,36995,36998,37000,92412,92413,92415,101799,111136,111138) (111139,114817). However, bovine colostrum is derived from animals, and there is some concern about contamination with diseased animal parts (1825). So far, there are no reports of disease transmission to humans due to use of contaminated bovine colostrum.
POSSIBLY SAFE ...when used rectally and appropriately, short-term. Bovine colostrum has been used with apparent safety when administered as a 10% enema twice weekly for up to 4 weeks (9730). ...when used intravaginally and appropriately, short-term. Bovine colostrum has been used with apparent safety when administered vaginally as a tablet twice weekly for up to 6 months, as a 1% cream once daily for up to 15 days, or as a gel containing 2.3% bovine colostrum daily for 12 weeks (92424,98819,101794). There is insufficient reliable information available about the safety of bovine colostrum when used topically.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
Bovine colostrum has been used with apparent safety in children for 1-3 months (92420,95924,101797,114819). There is insufficient reliable information available about the safety of long-term use of bovine colostrum in children.
CHILDREN: POSSIBLY UNSAFE
when used enterally in very preterm infants in the first few weeks of life.
Enterally, bovine colostrum added to breastmilk for very preterm infant feeding in the first 14 days of life has been associated with a higher rate of periventricular leukomalacia when compared with preterm formula added to breastmilk in one clinical trial (114816). Orally, the addition of bovine colostrum to breastmilk for very preterm infant feeding resulted in infants requiring more calcium and phosphate supplementation to maintain acceptable blood levels when compared with conventional fortifier in one clinical trial (114822).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally or intravenously and appropriately. Calcium is safe when used in appropriate doses (7555,12928,12946,95817). However, excessive doses should be avoided. The Institute of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: Age 0-6 months, 1000 mg; 6-12 months, 1500 mg; 1-8 years, 2500 mg; 9-18 years, 3000 mg; 19-50 years, 2500 mg; 51+ years, 2000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stone, hypercalciuria, hypercalcemia, and milk-alkali syndrome. There has also been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI). Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233). However, these studies, particularly meta-analyses, have been criticized for excluding trials in which calcium was administered with vitamin D (94137). Other clinical studies suggest that, when combined with vitamin D supplementation, calcium supplementation is not associated with an increased risk of CVD, CHD, or MI (93533,107231). Other analyses report conflicting results and have not shown that calcium intake affects the risk of CVD, CHD, or MI (92994,93533,97308,107231). Advise patients not to consume more than the recommended daily intake of 1000-1200 mg per day, to consider total calcium intake from both dietary and supplemental sources (17484), and to combine calcium supplementation with vitamin D supplementation (93533).
POSSIBLY UNSAFE ...when used orally in excessive doses. The National Academy of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: 19-50 years, 2500 mg; 51 years and older, 2000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stones, hypercalciuria, hypercalcemia, and milk-alkali syndrome. There has also been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI). Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233). However, these studies, particularly meta-analyses, have been criticized for excluding trials in which calcium was administered with vitamin D (94137). Other clinical studies suggest that, when combined with vitamin D supplementation, calcium supplementation is not associated with an increased risk of CVD, CHD, or MI (93533,107231). Other analyses report conflicting results and have not shown that calcium intake affects the risk of CVD, CHD, or MI (92994,93533,97308,107231). Advise patients to not consume more than the recommended daily intake of 1000-1200 mg per day, to consider total calcium intake from both dietary and supplemental sources (17484), and to combine calcium supplementation with vitamin D supplementation (93533).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
Calcium is safe when used in appropriate doses (17506).
CHILDREN: POSSIBLY UNSAFE
when used orally in excessive doses.
The Institute of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: 0-6 months, 1000 mg; 6-12 months, 1500 mg; 1-8 years, 2500 mg; 9-18 years, 3000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stones, hypercalciuria, hypercalcemia, and milk-alkali syndrome.
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately (945,1586,3263,3264,17506).
The World Health Organization (WHO) recommends prescribing oral calcium supplementation 1.5-2 grams daily during pregnancy to those with low dietary calcium intake to prevent pre-eclampsia (97347).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
The Institute of Medicine sets the same daily tolerable upper intake level (UL) for calcium according to age independent of pregnancy status: 9-18 years, 3000 mg; 19-50 years, 2500 mg (17506). Doses over these amounts might increase the risk of neonatal hypocalcemia-induced seizures possibly caused by transient neonatal hypoparathyroidism in the setting of excessive calcium supplementation during pregnancy, especially during the third trimester. Neonatal hypocalcemia is a risk factor for neonatal seizures (97345).
There is insufficient reliable information available about the safety of chrysin.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Deer velvet powder has been used with apparent safety at a dose of 1-1.5 grams daily for up to 10-12 weeks (47106,47108).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in amounts commonly found in foods. The typical diet supplies 2-24 mg of diindolylmethane daily (7170,7176,7664).
POSSIBLY SAFE ...when used orally and appropriately in medicinal doses. Diindolylmethane has been used with apparent safety at a dose of 45 mg daily for up to 6 months or at a higher dose of 100-140 mg daily for up to 3 months (47709,47729,93836,103830).
POSSIBLY UNSAFE ...when used orally in doses of 600 mg daily. In one clinical study, two cases of grade 3 asymptomatic hyponatremia were associated with taking diindolylmethane 600 mg daily (47729).
CHILDREN: LIKELY SAFE
when used orally in amounts commonly found in foods.
The typical diet supplies 2-24 mg of diindolylmethane daily (7170,7176,7664).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts commonly found in foods.
The typical diet supplies 2-24 mg of diindolylmethane daily (7170,7176,7664). There is insufficient reliable information available about the safety of diindolylmethane when used in amounts greater than those found in foods during pregnancy and lactation; avoid using.
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts. Eurycoma longifolia has been safely used in doses of 400 mg daily for up to 3 months and in doses of 200 mg daily for up to 9 months (17924,18138,93490,97312).
POSSIBLY UNSAFE ...when used orally in excessive amounts, long-term. There are some concerns about the safety of Eurycoma longifolia due to contamination with mercury and lead or adulteration with sildenafil (17925,17926,17927,18137,49087,93494). Some research shows that 36% and 17% of Eurycoma longifolia preparations from Malaysia contain high levels of mercury and lead, respectively (17925,17926,17927,49087). While safety issues related to these contaminants have not been reported in humans, taking high doses of Eurycoma longifolia long-term might cause symptoms of heavy metal poisoning or sildenafil-related adverse effects.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Animal research suggests that there are no negative effects of Eurycoma longifolia on the offspring (93493). However, research in humans is lacking.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Fenugreek has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when the seed is used orally in medicinal amounts. Fenugreek seed powder 5-10 grams daily has been used with apparent safety for up to 3 years. Fenugreek seed extract 1 gram daily has been used with apparent safety for up to 3 months (7389,9783,18359,18362,49868,90112,90113,90117,93419,93420)(93421,93422,93423,96065,103285,108704).
CHILDREN: LIKELY SAFE
when used orally in amounts commonly found in foods (4912).
There is insufficient reliable information available about the safety of fenugreek when used in larger amounts. Unusual body and urine odor has been reported after consumption of fenugreek tea. Although the odor appears to be harmless, it may be misdiagnosed as maple syrup urine disease (9782,96068).
PREGNANCY: LIKELY UNSAFE
when used orally in amounts greater than those found in food.
Fenugreek has potential oxytoxic and uterine stimulant activity (12531). There are case reports of congenital malformations, including hydrocephalus, anencephaly, cleft palate, and spina bifida, after consumption of fenugreek seeds during pregnancy (96068). Consumption of fenugreek immediately prior to delivery may cause the neonate to have unusual body odor. Although this does not appear to cause long-term sequelae, it may be misdiagnosed as maple syrup urine disease (9781,96068).
LACTATION: POSSIBLY SAFE
when used orally to stimulate lactation, short-term.
Although most available clinical studies lack safety testing in the lactating parent or infant (12535,22569,22570), some evidence suggests that taking fenugreek 1725 mg three times daily orally for 21 days does not cause negative side effects in the infant (90115).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts. Doses up to 400 mg daily have been used safely for 3-76 months (7173,93239,93240,93241). There is also some evidence that 400 mg twice daily can be used safely for 4 weeks (93242).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately in medicinal amounts.
There is limited evidence from 9 children with recurrent respiratory papillomatosis that indole-3-carbinol can be safely used in children ages 1.2-16 years for 12-76 months at doses of 6-17 mg/kg of body weight daily (7172,93239).
PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of indole-3-carbinol when used during pregnancy and lactation; avoid using.
LIKELY SAFE ...when used orally and appropriately. Oral magnesium is safe when used in doses below the tolerable upper intake level (UL) of 350 mg daily (7555). ...when used parenterally and appropriately. Parenteral magnesium sulfate is an FDA-approved prescription product (96484).
POSSIBLY UNSAFE ...when used orally in excessive doses. Doses greater than the tolerable upper intake level (UL) of 350 mg daily frequently cause loose stools and diarrhea (7555).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
Magnesium is safe when used in doses below the tolerable upper intake level (UL) of 65 mg daily for children 1 to 3 years, 110 mg daily for children 4 to 8 years, and 350 mg daily for children older than 8 years (7555,89396). ...when used parenterally and appropriately (96483).
CHILDREN: LIKELY UNSAFE
when used orally in excessive doses.
Tell patients not to use doses above the tolerable upper intake level (UL). Higher doses can cause diarrhea and symptomatic hypermagnesemia including hypotension, nausea, vomiting, and bradycardia (7555,8095).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Magnesium is safe for those pregnant and breast-feeding when used in doses below the tolerable upper intake level (UL) of 350 mg daily (7555).
PREGNANCY AND LACTATION: POSSIBLY SAFE
when prescription magnesium sulfate is given intramuscularly and intravenously prior to delivery for up to 5 days (12592,89397,99354,99355).
However, due to potential adverse effects associated with intravenous and intramuscular magnesium, use during pregnancy is limited to patients with specific conditions such as severe pre-eclampsia or eclampsia. There is some evidence that intravenous magnesium can increase fetal mortality and adversely affect neurological and skeletal development (12590,12593,60818,99354,99355). However, a more recent analysis of clinical research shows that increased risk of fetal mortality seems to occur only in the studies where antenatal magnesium is used for tocolysis and not for fetal neuroprotection or pre-eclampsia/eclampsia (102457). Furthermore, antenatal magnesium does not seem to be associated with increased risk of necrotizing enterocolitis in preterm infants (104396). There is also concern that magnesium increases the risk of maternal adverse events. A meta-analysis of clinical research shows that magnesium sulfate might increase the risk of maternal adverse events, especially in Hispanic mothers compared to other racial and ethnic groups (60971,99319).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
Tell patients to avoid exceeding the tolerable upper intake level (UL) of 350 mg daily. Taking magnesium orally in higher doses can cause diarrhea (7555). ...when prescription magnesium sulfate is given intramuscularly and intravenously prior to delivery for longer than 5 days (12592,89397,99354,99355). Maternal exposure to magnesium for longer than 5-7 days is associated with an increase in neonatal bone abnormalities such as osteopenia and fractures. The U.S. Food and Drug Administration (FDA) recommends that magnesium injection not be given for longer than 5-7 days (12590,12593,60818,99354,99355).
POSSIBLY SAFE ...when used orally and appropriately as extracts. A maitake mushroom extract 3 mg/kg twice daily has been used safely for up to 12 weeks (92843). Doses up to 5 mg/kg twice daily of another maitake mushroom extract have been used safely for up to 3 weeks (61239). Maitake mushroom polysaccharides (MMP) 1-1.5 grams daily have also been used safely for up to 2 years (8188).

LIKELY SAFE ...when used orally in amounts commonly found in foods. Sage is approved for use as a food in the United States (4912).
POSSIBLY SAFE ...when used orally in medicinal doses, short-term. Common sage (Salvia officinalis) and Spanish sage (Salvia lavandulaefolia) have been used with apparent safety when taken orally in doses of 280 mg daily for up to 8 weeks (10334,10810,17177,105338). ...when used topically. Common sage (Salvia officinalis) has been used with apparent safety as a single agent or in combination products for up to one week (10437,72619,107023). ...when the essential oil is inhaled as aromatherapy, short-term (72658).
POSSIBLY UNSAFE ...when used orally in high doses or long-term (12,1304). Some species of sage, including common sage (Salvia officinalis), contain a thujone constituent that can be toxic if consumed in large enough quantities (12,1304).
PREGNANCY: LIKELY UNSAFE
when used orally.
The constituent thujone can have menstrual stimulant and abortifacient effects (19).
LACTATION: POSSIBLY UNSAFE
when used orally; sage is thought to reduce the supply of mother's milk (19).
LIKELY SAFE ...when consumed in typical food amounts (6).
POSSIBLY SAFE .... ..when the shiitake mushroom extract AHCC is used orally and appropriately. AHCC 4.5-6 grams daily has been used with apparent safety in clinical trials lasting up to 6 months (22926,30419). Population research identified no safety concerns with the use of AHCC 3 grams daily for up to 9 years (30353,94830).
POSSIBLY UNSAFE ...when shiitake mushroom powder is used orally in medicinal amounts. Ingestion of shiitake mushroom powder 4 grams daily for 10 weeks can cause eosinophilia (1149). ...when uncooked shiitake mushroom is ingested. The lentinan component, which is broken down by heat, can cause toxic reactions, including shiitake dermatitis (94354).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid consuming greater than food amounts.
LIKELY UNSAFE ...when the spine-covered fruit is used orally. There have been reports of bilateral pneumothorax and bronchial polyp after oral consumption of the spine-covered fruit (818).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Animal research suggests that tribulus might adversely affect fetal development (12674); avoid using.
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. Zinc is safe in amounts that do not exceed the tolerable upper intake level (UL) of 40 mg daily (7135). ...when used topically and appropriately (2688,6538,6539,7135,8623,11051,111291).
POSSIBLY SAFE ...when used orally and appropriately in doses higher than the tolerable upper intake level (UL). Because the UL of zinc is based on regular daily intake, short-term excursions above 40 mg daily are not likely to be harmful. In fact, there is some evidence that doses of elemental zinc as high as 80 mg daily in combination with copper 2 mg can be used safely for approximately 6 years without significant adverse effects (7303,8622,92212). However, there is some concern that doses higher than the UL of 40 mg daily might decrease copper absorption and result in anemia (7135).
POSSIBLY UNSAFE ...when used intranasally. Case reports and animal research suggest that intranasal zinc might cause permanent anosmia or loss of sense of smell (11155,11156,11703,11704,11705,11706,11707,16800,16801,17083). Several hundred reports of anosmia have been submitted to the US Food and Drug Administration (FDA) and the manufacturer of some intranasal zinc products (Zicam) (16800,16801). Advise patients not to use intranasal zinc products.
LIKELY UNSAFE ...when taken orally in excessive amounts. Ingestion of 10-30 grams of zinc sulfate can be lethal in adults (7135). Chronic intake of 450-1600 mg daily can cause multiple forms of anemia, copper deficiency, and myeloneuropathies (7135,17092,17093,112473). This has been reported with use of zinc-containing denture adhesives in amounts exceeding the labeled directions, such as several times a day for several years (17092,17093). Advise patients to follow the label directions on denture adhesives that contain zinc.
CHILDREN: LIKELY SAFE
when used orally and appropriately (7135).
Zinc is safe in amounts that do not exceed the tolerable upper intake level (UL). The UL for children is based on age: 4 mg daily for 0-6 months, 5 mg daily for 7-12 months, 7 mg daily for 1-3 years, 12 mg daily for 4-8 years, 23 mg daily for 9-13 years, and 34 mg daily for 14-18 years (7135,97140).
CHILDREN: POSSIBLY UNSAFE
when used orally in high doses.
Taking amounts greater than the UL can cause sideroblastic anemia and copper deficiency (7135). ...when used topically on damaged skin. An infant treated with 10% zinc oxide ointment for severe diaper rash with perianal erosions developed hyperzincemia. Absorption seemed to occur mainly via the erosions; plasma levels dropped after the erosions healed despite continued use of the ointment (106905).
PREGNANCY: LIKELY SAFE
when used orally and appropriately.
Zinc is safe in amounts that do not exceed the tolerable upper intake level (UL) of 34 mg daily during pregnancy in those 14-18 years of age and 40 mg daily in those 19-50 years of age (7135).
PREGNANCY: LIKELY UNSAFE
when used orally in doses exceeding the UL (7135).
LACTATION: LIKELY SAFE
when used orally and appropriately.
Zinc is safe in amounts that do not exceed the tolerable upper intake level (UL) of 34 mg daily during lactation in those 14-18 years of age, and 40 mg daily for those 19-50 years of age (7135).
LACTATION: POSSIBLY UNSAFE
when used orally in doses exceeding the UL.
Higher doses can cause zinc-induced copper deficiency in nursing infants (7135).

Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Details
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion (19281,19282,97292). In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism (97292).

Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease (21631). However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption (93006).
|
Calcium reduces the absorption of bisphosphonates.
Details
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates (12937).
|
Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Details
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia (12938). Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.
|
Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Details
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects (6124). But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers (12939,12947).
|
Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Details
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction (15794,21632). So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.
|
Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Details
|
Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Details
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation (10574). Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.
|
Calcium seems to reduce levels of dolutegravir.
Details
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation (93578).
|
Calcium seems to reduce levels of elvitegravir.
Details
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation (94166).
|
Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Details
|
Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Details
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients (38953). Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.
|
Calcium seems to reduce the absorption of quinolone antibiotics.
Details
|
Calcium may reduce levels of raltegravir.
Details
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir (94164). However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure (94165).
|
Calcium seems to reduce the absorption of sotalol.
Details
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes (10018).
|
Calcium seems to reduce the absorption of tetracycline antibiotics.
Details
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut (1843).
|
Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Details
Thiazides reduce calcium excretion by the kidneys (1902). Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.
|
Theoretically, calcium may reduce the therapeutic effects of verapamil.
Details
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation (10574). Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.

Theoretically, chrysin might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, chrysin might increase the effects and adverse effects of aromatase inhibitors.
Details
|
Theoretically, chrysin might reduce the efficacy of estrogen-containing contraceptive drugs.
Details
|
Theoretically, chrysin might increase levels of drugs metabolized by CYP1A2.
Details
In vitro research suggests that chrysin inhibits CYP1A2 isozymes (7503,8172,42936,42956). However, chrysin does not appear to inhibit CYP1A2-dependent caffeine metabolism in animals (93643). Due to chrysin's low bioavailability and rapid metabolism to glucuronide and sulfate conjugates, this interaction is unlikely (7502,7504,7505,8168,42931,42938,93643).
|
Theoretically, chrysin might increase the effects and adverse effects of diclofenac.
Details
|
Theoretically, chrysin might decrease the effects of estrogen therapy.
Details
|
Theoretically, chrysin might increase the clearance of drugs that are UGT1A1 substrates, thereby reducing their effectiveness.
Details
|
Theoretically, chrysin might increase the effects and adverse effects of mephenytoin.
Details
In vitro research suggests that chrysin and its sulfate and glucuronide conjugates inhibit S-mephenytoin metabolism. It is speculated that chrysin and its conjugates reduce the metabolism of S-mephenytoin by inhibiting cytochrome P450 2C19 (106436). This effect has not been reported in humans.
|
Theoretically, chrysin might increase the effects and adverse effects of testosterone.
Details
In vitro research suggests that chrysin and its sulfate conjugate inhibit testosterone metabolism. It is speculated that chrysin and its sulfate conjugate reduce the metabolism of testosterone by inhibiting cytochrome P450 3A4 (106436). This effect has not been reported in humans.

Theoretically, deer velvet might interfere with the effectiveness of contraceptive drugs.
Details
|
Theoretically, deer velvet might increase the effects and side effects of estrogens.
Details
|
Theoretically, diindolylmethane might lower serum levels of CYP1A2 substrates.
Details
|
Theoretically, diindolylmethane might increase the risk of hyponatremia if used with sodium-depleting diuretics.
Details
Large doses of diindolylmethane (600 mg daily) have been associated with two cases of asymptomatic hyponatremia in clinical research (47729).
|
Theoretically, diindolylmethane might increase or decrease the effects of estrogens.
Details
Diindolylmethane might have mild estrogenic or antiestrogenic effects (7664). Theoretically, large amounts of diindolylmethane might interfere with hormone replacement therapy.
|
Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
Details
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes (93489). This effect has not been reported in humans.
|
Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
Details
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes (93489). This effect has not been reported in humans.
|
Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
Details
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes (93489). This effect has not been reported in humans.
|
Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
Details
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism (17923). It is not known if separating administration will prevent this interaction.
|
Theoretically, Eurycoma longifolia may further increase levels of testosterone.
Details
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo (108451). It is unclear whether this increase would occur in individuals with normal testosterone levels.
|
Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.
Details
Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels (5191,7389,49643).
|
Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.
Details
|
Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.
Details
Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11% (108701).
|
Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.
Details
Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg (108703).
|
Theoretically, fenugreek might decrease plasma levels of phenytoin.
Details
Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance (110905). So far, this interaction has not been reported in humans.
|
Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.
Details
Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively (110898). So far, this interaction has not been reported in humans.
|
Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.
Details
Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22% (90118).
|
Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).
Details
|
Theoretically, indole-3-carbinol might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Details
In vitro research shows that indole-3-carbinol inhibits platelet aggregation (98611).
|
Theoretically, indole-3-carbinol might increase the metabolism of CYP1A2 substrates and lower serum concentrations.
Details
Animal research shows that indole-3-carbinol induces CYP1A2 enzymes (7187).
|
Indole-3-carbinol might interfere with the effects of estrogen therapy.
Details
|
Concomitant use of aminoglycoside antibiotics and magnesium can increase the risk for neuromuscular weakness.
Details
Both aminoglycosides and magnesium reduce presynaptic acetylcholine release, which can lead to neuromuscular blockade and possible paralysis. This is most likely to occur with high doses of magnesium given intravenously (13362).
|
Use of acid reducers may reduce the laxative effect of magnesium oxide.
Details
A retrospective analysis shows that, in the presence of H2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs), a higher dose of magnesium oxide is needed for a laxative effect (90033). This may also occur with antacids. Under acidic conditions, magnesium oxide is converted to magnesium chloride and then to magnesium bicarbonate, which has an osmotic laxative effect. By reducing acidity, antacids may reduce the conversion of magnesium oxide to the active bicarbonate salt.
|
Theoretically, magnesium may have antiplatelet effects, but the evidence is conflicting.
Details
In vitro evidence shows that magnesium sulfate inhibits platelet aggregation, even at low concentrations (20304,20305). Some preliminary clinical evidence shows that infusion of magnesium sulfate increases bleeding time by 48% and reduces platelet activity (20306). However, other clinical research shows that magnesium does not affect platelet aggregation, although inhibition of platelet-dependent thrombosis can occur (60759).
|
Magnesium can decrease absorption of bisphosphonates.
Details
Cations, including magnesium, can decrease bisphosphonate absorption. Advise patients to separate doses of magnesium and these drugs by at least 2 hours (13363).
|
Magnesium can have additive effects with calcium channel blockers, although evidence is conflicting.
Details
Magnesium inhibits calcium entry into smooth muscle cells and may therefore have additive effects with calcium channel blockers. Severe hypotension and neuromuscular blockades may occur when nifedipine is used with intravenous magnesium (3046,20264,20265,20266), although some contradictory evidence suggests that concurrent use of magnesium with nifedipine does not increase the risk of neuromuscular weakness (60831). High doses of magnesium could theoretically have additive effects with other calcium channel blockers.
|
Magnesium salts may reduce absorption of digoxin.
Details
|
Gabapentin absorption can be decreased by magnesium.
Details
Clinical research shows that giving magnesium oxide orally along with gabapentin decreases the maximum plasma concentration of gabapentin by 33%, time to maximum concentration by 36%, and area under the curve by 43% (90032). Advise patients to take gabapentin at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
|
Magnesium might precipitate ketamine toxicity.
Details
In one case report, a 62-year-old hospice patient with terminal cancer who had been stabilized on sublingual ketamine 150 mg four times daily experienced severe ketamine toxicity lasting for 2 hours after taking a maintenance dose of ketamine following an infusion of magnesium sulfate 2 grams (105078). Since both magnesium and ketamine block the NMDA receptor, magnesium is thought to have potentiated the effects of ketamine.
|
Magnesium can reduce the bioavailability of levodopa/carbidopa.
Details
Clinical research in healthy volunteers shows that taking magnesium oxide 1000 mg with levodopa 100 mg/carbidopa 10 mg reduces the area under the curve (AUC) of levodopa by 35% and of carbidopa by 81%. In vitro and animal research shows that magnesium produces an alkaline environment in the digestive tract, which might lead to degradation and reduced bioavailability of levodopa/carbidopa (100265).
|
Potassium-sparing diuretics decrease excretion of magnesium, possibly increasing magnesium levels.
Details
Potassium-sparing diuretics also have magnesium-sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics (9613,9614,9622). Theoretically, increased magnesium levels could result from concomitant use of potassium-sparing diuretics and magnesium supplements.
|
Magnesium decreases absorption of quinolones.
Details
Magnesium can form insoluble complexes with quinolones and decrease their absorption (3046). Advise patients to take these drugs at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
|
Sevelamer may increase serum magnesium levels.
Details
In patients on hemodialysis, sevelamer use was associated with a 0.28 mg/dL increase in serum magnesium. The mechanism of this interaction remains unclear (96486).
|
Parenteral magnesium alters the pharmacokinetics of skeletal muscle relaxants, increasing their effects and accelerating the onset of effect.
Details
Parenteral magnesium shortens the time to onset of skeletal muscle relaxants by about 1 minute and prolongs the duration of action by about 2 minutes. Magnesium potentiates the effects of skeletal muscle relaxants by decreasing calcium-mediated release of acetylcholine from presynaptic nerve terminals, reducing postsynaptic sensitivity to acetylcholine, and having a direct effect on the membrane potential of myocytes (3046,97492,107364). Magnesium also has vasodilatory actions and increases cardiac output, allowing a greater amount of muscle relaxant to reach the motor end plate (107364). A clinical study found that low-dose rocuronium (0.45 mg/kg), when given after administration of magnesium 30 mg/kg over 10 minutes, has an accelerated onset of effect, which matches the onset of effect seen with a full-dose rocuronium regimen (0.6 mg/kg) (96485). In another clinical study, onset times for rocuronium doses of 0.3, 0.6, and 1.2 mg/kg were 86, 76, and 50 seconds, respectively, when given alone, but were reduced to 66, 44, and 38 seconds, respectively, when the doses were given after a 15-minute infusion of magnesium sulfate 60 mg/kg (107364). Giving intraoperative intravenous magnesium sulfate, 50 mg/kg loading dose followed by 15 mg/kg/hour, reduces the onset time of rocuronium, enhances its clinical effects, reduces the dose of intraoperative opiates, and prolongs the spontaneous recovery time (112781,112782). It does not affect the activity of subsequently administered neostigmine (112782).
|
Magnesium increases the systemic absorption of sulfonylureas, increasing their effects and side effects.
Details
Clinical research shows that administration of magnesium hydroxide with glyburide increases glyburide absorption, increases maximal insulin response by 35-fold, and increases the risk of hypoglycemia, when compared with glyburide alone (20307). A similar interaction occurs between magnesium hydroxide and glipizide (20308). The mechanism of this effect appears to be related to the elevation of gastrointestinal pH by magnesium-based antacids, increasing solubility and enhancing absorption of sulfonylureas (22364).
|
Magnesium decreases absorption of tetracyclines.
Details
Magnesium can form insoluble complexes with tetracyclines in the gut and decrease their absorption and antibacterial activity (12586). Advise patients to take these drugs 1 hour before or 2 hours after magnesium supplements.
|
Theoretically, combining maitake mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Clinical research shows that taking maitake mushroom polysaccharide (MMP) can lower blood glucose levels in patients with types 2 diabetes (8188).
|
Theoretically, combining maitake mushroom with antihypertensive drugs might increase the risk of hypotension.
Details
|
There is limited evidence that maitake mushroom may increase the anticoagulant effects of warfarin.
Details
In a case report, a patient previously stabilized on warfarin developed an elevated international normalized ratio (INR) of 5.1 after taking maitake mushroom (Grifron-Pro Maitake D-Fraction) 1 drop/kg daily in three divided doses for one week. The elevated INR resolved after holding warfarin for two days, then reducing the dose by 11%. It is thought that the beta-glucan constituent of maitake mushroom might cause warfarin dissociation from proteins, resulting in increased free warfarin levels and increased warfarin effects (17209).
|
In vitro research shows that maral root tincture can reduce platelet aggregation (27412). Theoretically, maral root might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs. Some of these drugs include aspirin, clopidogrel (Plavix), nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.

Theoretically, sage might decrease the clinical effects of anticholinergic drugs.
Details
|
Theoretically, sage might interfere with the clinical effects of anticonvulsant drugs.
Details
Some species of sage can cause convulsions when consumed in large quantities (10812).
|
Theoretically, taking sage with antidiabetes drugs might increase the risk of hypoglycemia.
Details
In patients with polycystic ovary syndrome (PCOS) or inadequately controlled type 2 diabetes, common sage (Salvia officinalis) has demonstrated hypoglycemic activity (91971,103380). However, other clinical research in patients with inadequately controlled type 2 diabetes shows that common sage extract does not lower fasting blood glucose levels (105340).
|
Theoretically, sage might increase or decrease the effects of antihypertensive drugs.
Details
Animal research suggests that common sage (Salvia officinalis) can cause prolonged blood pressure reduction (4152). However, clinical research suggests that Spanish sage (Salvia lavandulaefolia) can increase blood pressure in some people with hypertension (10334). Until more is known, use with caution.
|
Theoretically, taking sage might increase the sedative and adverse effects of benzodiazepines.
Details

Details
|
Theoretically, taking sage might increase the sedative and adverse effects of CNS depressants.
Details
Some constituents of sage have CNS depressant activity (10334).
|
Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP2C19.
Details

Details
|
Theoretically, sage might decrease the levels and clinical effects of drugs metabolized by CYP2E1.

|
Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP3A4.
Details
|
Theoretically, sage might interfere with hormone therapy.
Details
In vitro evidence suggests that geraniol, a constituent of Spanish sage (Salvia lavandulaefolia), exerts estrogenic activity (39572). The clinical significance of this effect is unclear.
|
Theoretically, sage might increase levels of drugs transported by P-glycoprotein.
Details
In vitro research suggests that common sage (Salvia officinalis) can inhibit the multi-drug transporter protein, P-glycoprotein (72641). This effect has not been reported in humans.
|
Theoretically, shiitake mushroom might decrease levels of drugs metabolized by CYP2D6.
Details
|
Theoretically, taking shiitake mushroom might decrease the effects of immunosuppressive therapy.
Details
|
Taking tribulus with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Clinical research shows that Tribulus can lower blood glucose levels in adults with type 2 diabetes who are taking antidiabetes medications (97327).
|
Theoretically, taking tribulus with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, tribulus might increase the levels and clinical effects of lithium.
Details
Tribulus is thought to have diuretic properties (12681). Due to these potential diuretic effects, tribulus might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
|
Amiloride can modestly reduce zinc excretion and increase zinc levels.
Details
Clinical research shows that amiloride can reduce urinary zinc excretion, especially at doses of 10 mg per day or more. This zinc-sparing effect can help to counteract zinc losses caused by thiazide diuretics, but it is unlikely to cause zinc toxicity at usual amiloride doses (830,11626,11627,11634). The other potassium-sparing diuretics, spironolactone (Aldactone) and triamterene (Dyrenium), do not seem to have a zinc-sparing effect.
|
Zinc modestly reduces levels of atazanavir, although this effect does not seem to be clinically significant.
Details
Clinical research shows that zinc might decrease serum atazanavir levels by chelating with atazanavir in the gut and preventing its absorption (93578). Although a single dose of zinc sulfate (Solvazinc tablets) 125 mg orally does not affect atazanavir concentrations in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate 125 mg daily for 2 weeks reduces plasma levels of atazanavir by about 22% in these patients. However, despite this decrease, atazanavir levels still remain at high enough concentrations for the prevention of HIV virus replication (90216).
|
Zinc might decrease cephalexin levels by chelating with cephalexin in the gut and preventing its absorption.
Details
A pharmacokinetic study shows that zinc sulfate 250 mg taken concomitantly with cephalexin 500 mg decreases peak levels of cephalexin by 31% and reduces the exposure to cephalexin by 27%. Also, taking zinc sulfate 3 hours before cephalexin decreases peak levels of cephalexin by 11% and reduces the exposure to cephalexin by 18%. By decreasing cephalexin levels, zinc might increase the risk of treatment failure. This effect does not occur when zinc is taken 3 hours after the cephalexin dose (94163). To avoid an interaction, advise patients take zinc sulfate 3 hours after taking cephalexin.
|
Theoretically, zinc might interfere with the therapeutic effects of cisplatin.
Details
Animal research suggests that zinc stimulates tumor cell production of the protein metallothionein, which binds and inactivates cisplatin (11624,11625). It is not known whether zinc supplements or high dietary zinc intake can cause clinically significant interference with cisplatin therapy. Cisplatin might also increase zinc excretion.
|
Theoretically, taking zinc along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Details
|
Zinc might reduce the levels and clinical effects of penicillamine.
Details
By forming an insoluble complex with penicillamine, zinc interferes with penicillamine absorption and activity. Zinc supplements reduce the efficacy of low-dose penicillamine (0.5-1 gram/day), but do not seem to affect higher doses (1-2.75 gram/day), provided dosing times are separated (2678,4534,11605). Advise patients to take zinc and penicillamine at least 2 hours apart.
|
Zinc can decrease the levels and clinical effects of quinolones antibiotics.
Details
|
Zinc modestly reduces levels of ritonavir.
Details
Clinical research shows that zinc might reduce serum ritonavir levels by chelating with ritonavir in the gut and preventing its absorption (93578). In patients with HIV, ritonavir is taken with atazanavir to prevent the metabolism and increase the effects of atazanavir. A pharmacokinetic study shows that, in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate (Solvazinc tablets) 125 mg as a single dose or as multiple daily doses for 2 weeks reduces plasma levels of ritonavir by about 16% (90216). However, atazanavir levels still remains high enough to prevent HIV virus replication. Therefore, the decrease in ritonavir levels is not likely to be clinically significant.
|
Zinc might reduce levels of tetracycline antibiotics.
Details
Tetracyclines form complexes with zinc in the gastrointestinal tract, which can reduce absorption of both the tetracycline and zinc when taken at the same time (3046,4945). Taking zinc sulfate 200 mg with tetracycline reduces absorption of the antibiotic by 30% to 40% (11615). Demeclocycline and minocycline cause a similar interaction (4945). However, doxycycline does not seem to interact significantly with zinc (11615). Advise patients to take tetracyclines at least 2 hours before, or 4-6 hours after, zinc supplements to avoid any interactions.

Endocrine ...A case report describes a 73-year-old female who had taken an ashwagandha root extract (unspecified dose) for 2 years to treat hypothyroidism which had been previously managed with levothyroxine. The patient was diagnosed with hyperthyroidism after presenting with supraventricular tachycardia, chest pain, tremor, dizziness, fatigue, irritability, hair thinning, and low thyroid stimulating hormone (TSH) levels. Hyperthyroidism resolved after discontinuing ashwagandha (108745). Additionally, an otherwise healthy adult who was taking ashwagandha extract orally for 2 months experienced clinical and laboratory-confirmed thyrotoxicosis. Thyrotoxicosis resolved 50 days after discontinuing ashwagandha, without other treatment (114111). Another case report describes a 37-year-old female who presented with moderate symptomatic hyponatremia secondary to adrenal insufficiency after chronic consumption of ashwagandha for 2 years. This subject was effectively managed with oral hydrocortisone (114790).
Gastrointestinal ...Orally, large doses may cause gastrointestinal upset, diarrhea, and vomiting secondary to irritation of the mucous and serous membranes (3710). When taken orally, nausea and abdominal pain (19276,110490,113609) and gastritis and flatulence (90651) have been reported.
Genitourinary ...In one case report, a 28-year-old male with a decrease in libido who was taking ashwagandha 5 grams daily over 10 days subsequently experienced burning, itching, and skin and mucous membrane discoloration of the penis, as well as an oval, dusky, eroded plaque (3 cm) with erythema on the glans penis and prepuce (32537).
Hepatic ...Orally, ashwagandha in doses of 154 mg to 20 grams daily has played a role in several case reports of cholestatic, hepatocellular, and mixed liver injuries. In most of these cases, other causes of liver injury were excluded, and liver failure did not occur. Symptoms included jaundice, pruritus, malaise, fatigue, lethargy, weight loss, nausea, diarrhea, abdominal pain and distension, stool discoloration, and dark urine. Symptom onset was typically 5-180 days from first intake, although in some cases onset occurred after more than 12 months of use (102686,107372,110490,110491,111533,111535,112111,113610,114113). Laboratory findings include elevated aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, serum bilirubin, and international normalized ratio (INR) (112111,113610,114113). In most cases, liver enzymes normalized within 1-5 months after discontinuation of ashwagandha (102686,107372,110491,111535,112111,114113). However, treatment with corticosteroids, lactulose, ornithine, ursodeoxycholic acid, and plasmapheresis, among other interventions, was required in one case (111533). Rarely, use of oral ashwagandha has been reported to cause hepatic encephalopathy, liver failure requiring liver transplantation, and acute-on-chronic liver failure resulting in death (110490,113610).
Neurologic/CNS ...Orally, ashwagandha has been reported to cause drowsiness (110492,113609). Headache, neck pain, and blurry vision have been reported in a 47-year-old female taking ashwagandha, cannabis, and venlafaxine. Imaging over the course of multiple years and hospital admissions indicated numerous instances of intracranial hemorrhage and multifocal stenosis of intracranial arteries, likely secondary to reversible cerebral vasoconstriction syndrome (RCVS) (112113). It is unclear whether the RCVS and subsequent intracranial hemorrhages were precipitated by ashwagandha, cannabis, or venlafaxine.
General ...Orally, bovine colostrum is well tolerated.
Endocrine ...Enterally, the addition of bovine colostrum to breastmilk for very preterm infant feeding resulted in infants requiring more calcium and phosphate supplementation to maintain acceptable blood levels when compared with conventional fortifier in one clinical trial (114822).
Gastrointestinal ...Orally, bovine colostrum has caused nausea and vomiting in an individual with HIV-related cryptosporidiosis (4905). In clinical trials of bovine colostrum, bloating, nausea, diarrhea, and unsettled stomach have been reported as mild in nature by a few patients (92414,101792) with a similar rate of occurrence as those taking a whey-based control (114819).
Hematologic ...Orally, bovine colostrum has caused decreased serum hematocrit in HIV patients treated for infectious diarrhea (4905).
Hepatic ...Orally, bovine colostrum has caused elevated liver function tests in HIV patients treated for infectious diarrhea (4905).
Immunologic ...Topically, there is a case report of anaphylaxis, urticaria, and itching related to bovine colostrum (101793).
Neurologic/CNS ...Enterally , bovine colostrum has been associated with increased risk of periventricular leukomalacia in very preterm infants. Specifically, in a large, multi-center, clinical study conducted in 7 neonatal intensive care units in China, 5 cases of periventricular leukomalacia (PVL), diagnosed with magnetic resonance imaging, were reported among the 155 infants fed bovine colostrum supplemented breastmilk until postnatal day 14, while no cases were reported among the 181 infants receiving preterm formula supplemented breastmilk. Three of the 5 infants with PVL were fed small volumes of bovine colostrum (less than 10 mL/kg daily) while 2 were fed larger volumes of bovine colostrum (18-35 mL/kg daily). in addition to preterm formula (114816).
Renal ...Enterally, bovine colostrum added to breastmilk for infant feeding until postnatal day 14 among very preterm infants has been associated with higher blood urea nitrogen levels by about 3 mg/dL when compared with preterm formula added to breastmilk (114816).
Other ...Theoretical adverse effects to bovine colostrum include an allergic reaction in individuals allergic to bovine milk products. There is also some concern that bovine colostrum that is obtained from cows in countries where bovine spongiform encephalitis (BSE) has been reported might be unsafe, however, there is no research indicating that colostrum can be contaminated with the BSE-causing prion. Countries where BSE has been reported include Great Britain, France, The Netherlands, Portugal, Luxembourg, Ireland, Switzerland, Oman, and Belgium (1825). Until more is known, tell patients to avoid these products unless country of origin can be determined. Patients should avoid products that are produced in countries where BSE has been found.
General
...Orally and intravenously, calcium is well-tolerated when used appropriately.
Most Common Adverse Effects:
Orally: Belching, constipation, diarrhea, flatulence, and stomach upset.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about calciphylaxis and kidney stones.
Cardiovascular
...There has been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI).
Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233). However, these results, particularly meta-analyses, have been criticized for excluding trials in which calcium was administered with vitamin D (94137). Many of these trials also only included postmenopausal females. Other analyses report conflicting results, and have not shown that calcium intake affects the risk of CVD, CHD, or MI (92994,93533,97308,107231). Reasons for these discrepancies are not entirely clear. It may relate to whether calcium is taken as monotherapy or in combination with vitamin D. When taken with vitamin D, which is commonly recommended, calcium supplementation does not appear to be associated with an increased risk of CVD, CHD, or MI (93533,107231). Also, the association between calcium supplementation and CVD, CHD, or MI risk may be influenced by the amount of calcium consumed as part of the diet. Supplementation with calcium may be associated with an increased risk of MI in people with dietary calcium intake above 805 mg daily, but not in those with dietary calcium intake below 805 mg daily (17482). To minimize the possible risk of CVD, CHD, or MI, advise patients not to consume more than the recommended daily intake of 1000-1200 mg and to consider total calcium intake from both dietary and supplemental sources (17484). While dietary intake of calcium is preferred over supplemental intake, advise patients who require calcium supplements to take calcium along with vitamin D, as this combination does not appear to be associated with an increased risk of MI (93533).
Rarely, calcium intake can increase the risk of calciphylaxis, which usually occurs in patients with kidney failure. Calciphylaxis is the deposition of calcium phosphate in arterioles, which causes skin ulcers and skin necrosis. In a case report, a 64-year-old female with a history of neck fracture, sepsis, and ischemic colitis presented with painful leg ulcers due to calciphylaxis. She discontinued calcium and vitamin D supplementation and was treated with sodium thiosulfate and supportive care (95816).
Gastrointestinal ...Orally, calcium can cause belching, flatulence, nausea, gastrointestinal discomfort, and diarrhea (1824,1843,12950,38803). Although constipation is frequently cited as an adverse effect of calcium, there is no scientific substantiation of this side effect (1824,1843,1844,1845,12950,38978). Calcium carbonate has been reported to cause acid rebound, but this is controversial (12935,12936).
Oncologic ...There is some concern that very high doses of calcium might increase the risk of prostate cancer. Some epidemiological evidence suggests that consuming over 2000 mg/day of dietary calcium might increase the risk for prostate cancer (4825,12949). Additional research suggests that calcium intake over 1500 mg/day might increase the risk of advanced prostate cancer and prostate cancer mortality (14132). Consumption of dairy products has also been weakly linked to a small increase in prostate cancer risk (98894). However, contradictory research suggests no association between dietary intake of calcium and overall prostate cancer risk (14131,14132,104630). More evidence is needed to determine the effect of calcium, if any, on prostate cancer risk.
Renal ...Kidney stones have been reported in individuals taking calcium carbonate 1500 mg daily in combination with vitamin D 2000 IU daily for 4 years (93943).
General ...No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
General ...Orally, deer velvet powder or extract seems to be well tolerated, short-term. However, a thorough evaluation of safety outcomes has not been conducted.
General
...Orally, diindolylmethane is generally well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, gas, headache, nausea, rash, and vomiting.
Serious Adverse Effects (Rare):
Orally: Drug rash with eosinophilia and systemic symptoms (DRESS).
Dermatologic ...Orally, diindolylmethane can cause rash (47615,93836). In one case report, a patient developed drug rash with eosinophilia and systemic symptoms (DRESS) after consuming a product containing diindolylmethane, vitamin E, and broccoli powder. An allergen patch test was positive for diindolylmethane (93840).
Endocrine ...Orally, diindolylmethane was associated with grade 3 asymptomatic hyponatremia in 2 of 4 patients taking 600 mg daily for 28 days in one clinical study. Hyponatremia was not seen in the 8 patients taking diindolylmethane 150-450 mg daily (47729).
Gastrointestinal ...Orally, diindolylmethane can cause nausea, vomiting, diarrhea, and gas (47652,47676,47709,47729,93836).
Genitourinary ...Orally, diindolylmethane can cause the urine to darken (93836).
Hematologic ...In one case report, a 65-year-old male developed a deep vein thromboembolism (DVT) and bilateral pulmonary emboli (PE) within a few weeks of initiating treatment with diindolylmethane. It is unclear if diindolylmethane contributed to this event; the patient was at increased risk for emboli due to his age, weight, tobacco use, and possible history of pulmonary embolism (93835).
Hepatic ...In one case report, a patient developed drug rash with eosinophilia and systemic symptoms (DRESS), involving elevated liver transaminases, after consuming a product containing diindolylmethane, vitamin E, and broccoli powder. An allergen patch test was positive for diindolylmethane (93840).
Immunologic ...In one case report, a patient developed drug rash with eosinophilia and systemic symptoms (DRESS) after consuming a product containing diindolylmethane, vitamin E, and broccoli powder. The patient developed fever, activated lymphocytes, and swollen lymph nodes. An allergen patch test was positive for diindolylmethane (93840).
Musculoskeletal ...Orally, diindolylmethane has been reported to cause arthralgias (47615).
Neurologic/CNS ...Orally, diindolylmethane can cause headache (47652,47676,93836). One case has reported ischemic stroke in a 38-year-old female with a history of a patent foramen ovale (PFO), traumatic subdural hematoma, right partial hemicraniectomy, and use of several supplements, including 200 mg of diindolylmethane daily, vitamin D3, vitamin K2, elderberry, caffeine, and possibly cannabis (112895). It is unclear if diindolylmethane contributed to this event; the patient was at increased risk for stroke due to PFO and other factors.
General
...Orally, Eurycoma longifolia seems to be well tolerated.
Most Common Adverse Effects:
Orally: None reported.
Endocrine ...Some research in both humans and animals suggests that Eurycoma longifolia might increase testosterone levels (17924). If testosterone levels are increased beyond the normal range, there is risk of testosterone-related side effects which could include acne, insulin resistance, hepatotoxicity, and others.
General
...Orally, fenugreek seed is generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, bloating, diarrhea, dyspepsia, flatulence, hypoglycemia, and nausea.
Serious Adverse Effects (Rare):
All ROA: Severe allergic reactions including angioedema, bronchospasm, and shock.
Endocrine ...Orally, large doses of fenugreek seed, 100 grams daily of defatted powder, have caused hypoglycemia (164,96068).
Gastrointestinal ...Orally, fenugreek seed can cause mild gastrointestinal symptoms, such as diarrhea, dyspepsia, abdominal distention and pain, nausea, and flatulence, especially when taken on an empty stomach (622,12534,18349,93421,96065,96068,105016).
Immunologic ...Fenugreek can cause allergic reactions when used orally and topically, and when the powder is inhaled (719,96068). Orally, fenugreek has caused bronchospasm, diarrhea, and itching, and skin reactions severe enough to require intravenous human immunoglobulin (96068). Topically, fenugreek paste has resulted in facial swelling, wheezing, and numbness around the head (719,96068). When used both orally and topically by a single individual, asthma and rhinitis occurred (96068). Inhalation of fenugreek powder has resulted in fainting, sneezing, runny nose, and eye tearing (719,96068).
Neurologic/CNS ...Orally, loss of consciousness has occurred in a 5 week-old infant drinking tea made from fenugreek (9782). Dizziness and headaches have been reported in clinical research of fenugreek extract (49551,93419). However, these events are rare.
Renal ...Orally, fenugreek aqueous see extract may increase the frequency of micturition, although this even appears to be rare (49551).
Other
...Consumption of fenugreek during pregnancy, immediately prior to delivery, may cause the neonate to have an unusual body odor, which may be confused with maple syrup urine disease.
It does not appear to cause long-term sequelae (9781). This unusual body odor may also occur in children drinking fenugreek tea. A case of a specific urine and sweat smell following oral fenugreek extract use has been reported for a patient in one clinical trial (18349).
In 2011, outbreaks of enteroaggregative hemorrhagic Escherichia coli (EATEC) O104:H4 infection occurred in Germany and Spain. Epidemiological studies linked the outbreaks to fenugreek seeds that had been imported from Africa. However, laboratory analyses were unable to isolate the causative strain of bacteria from fenugreek seed samples (49776,49777,49781,90114).
General
...Orally, indole-3-carbinol seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, imbalance, nausea, rash, tremor, unsteadiness.
Dermatologic ...Orally, indole-3-carbinol has been associated with reports of rash (93242). A woman taking indole-3-carbinol 375 mg daily for treatment of systemic lupus erythematosus (SLE) developed a generalized maculopapular rash which resolved when indole-3-carbinol was discontinued and recurred when it was restarted (93240).
Gastrointestinal ...Orally, indole-3-carbinol increases gastrointestinal motility and has been associated with diarrhea (93242,93243).
Neurologic/CNS ...Indole-3-carbinol has been associated with reports of unsteadiness and imbalance, especially at higher doses (7172). An adult male taking 400 mg twice daily for treatment of recurrent respiratory papillomatosis developed imbalance and tremor after 10 days of treatment. This resolved when the dose was halved (93238). Two children who took 3 times the intended weight-based dose of indole-3-carbinol in one day developed unsteadiness and nausea (93238).
General
...Magnesium is generally well tolerated.
Some clinical research shows no differences in adverse effects between placebo and magnesium groups.
Most Common Adverse Effects:
Orally: Diarrhea, gastrointestinal irritation, nausea, and vomiting.
Intravenously: Bradycardia, dizziness, flushing sensation, hypotension, and localized pain and irritation. In pregnancy, may cause blurry vision, dizziness, lethargy, nausea, nystagmus, and perception of warmth.
Serious Adverse Effects (Rare):
All ROAs: With toxic doses, loss of reflexes and respiratory depression can occur. High doses in pregnancy can increase risk of neonatal mortality and neurological defects.
Cardiovascular
...Intravenously, magnesium can cause bradycardia, tachycardia, and hypotension (13356,60795,60838,60872,60960,60973,60982,61001,61031,114681).
Inhaled magnesium administered by nebulizer may also cause hypotension (113466). Magnesium sulfate may cause rapid heartbeat when administered antenatally (60915,114681).
In one case report, a 99-year-old male who took oral magnesium oxide 3000 mg daily for chronic constipation was hospitalized with hypermagnesemia, hypotension, bradycardia, heart failure, cardiomegaly, second-degree sinoatrial block, and complete bundle branch block. The patient recovered after discontinuing the magnesium oxide (108966).
Dermatologic ...Intravenously, magnesium may cause flushing, sweating, and problems at the injection site (including burning pain) (60960,60982,111696,114681). In a case study, two patients who received intravenous magnesium sulfate for suppression of preterm labor developed a rapid and sudden onset of an urticarial eruption (a skin eruption of itching welts). The eruption cleared when magnesium sulfate was discontinued (61045). Orally, magnesium oxide may cause allergic skin rash, but this is rare. In one case report, a patient developed a rash after taking 600 mg magnesium oxide (Maglax) (98291).
Gastrointestinal
...Orally, magnesium can cause gastrointestinal irritation, nausea, vomiting, and diarrhea (1194,4891,10661,10663,18111,60951,61016,98290).
In rare cases, taking magnesium orally might cause a bezoar, an indigestible mass of material which gets lodged in the gastrointestinal tract. In a case report, a 75-year-old female with advanced rectal cancer taking magnesium 1500 mg daily presented with nausea and anorexia from magnesium oxide bezoars in her stomach (99314). Magnesium can cause nausea, vomiting, or dry mouth when administered intravenously or by nebulization (60818,60960,60982,104400,113466,114681). Antenatal magnesium sulfate may also cause nausea and vomiting (60915,114681). Two case reports suggest that giving magnesium 50 grams orally for bowel preparation for colonoscopy in patients with colorectal cancer may lead to intestinal perforation and possibly death (90006).
Delayed meconium passage and obstruction have been reported rarely in neonates after intravenous magnesium sulfate was given to the mother during pregnancy (60818). In a retrospective study of 200 neonates born prematurely before 32 weeks of gestation, administration of prenatal IV magnesium sulfate, as a 4-gram loading dose and then 1-2 grams hourly, was not associated with the rate of meconium bowel obstruction when compared with neonates whose mothers had not received magnesium sulfate (108728).
Genitourinary ...Intravenously, magnesium sulfate may cause renal toxicity or acute urinary retention, although these events are rare (60818,61012). A case of slowed cervical dilation at delivery has been reported for a patient administered intravenous magnesium sulfate for eclampsia (12592). Intravenous magnesium might also cause solute diuresis. In a case report, a pregnant patient experienced polyuria and diuresis after having received intravenous magnesium sulfate in Ringer's lactate solution for preterm uterine contractions (98284).
Hematologic ...Intravenously, magnesium may cause increased blood loss at delivery when administered for eclampsia or pre-eclampsia (12592). However, research on the effect of intravenous magnesium on postpartum hemorrhage is mixed. Some research shows that it does not affect risk of postpartum hemorrhage (60982), while other research shows that intrapartum magnesium administration is associated with increased odds of postpartum hemorrhage, increased odds of uterine atony (a condition that increases the risk for postpartum hemorrhage) and increased need for red blood cell transfusions (97489).
Musculoskeletal
...Intravenously, magnesium may cause decreased skeletal muscle tone, muscle weakness, or hypocalcemic tetany (60818,60960,60973).
Although magnesium is important for normal bone structure and maintenance (272), there is concern that very high doses of magnesium may be detrimental. In a case series of 9 patients receiving long-term tocolysis for 11-97 days, resulting in cumulative magnesium sulfate doses of 168-3756 grams, a lower bone mass was noted in 4 cases receiving doses above 1000 grams. There was one case of pregnancy- and lactation-associated osteoporosis and one fracture (108731). The validity and clinical significance of this data is unclear.
Neurologic/CNS
...Intravenously, magnesium may cause slurred speech, dizziness, drowsiness, confusion, or headaches (60818,60960,114681).
With toxic doses, loss of reflexes, neurological defects, drowsiness, confusion, and coma can occur (8095,12589,12590).
A case report describes cerebral cortical and subcortical edema consistent with posterior reversible encephalopathy syndrome (PRES), eclampsia, somnolence, seizures, absent deep tendon reflexes, hard to control hypertension, acute renal failure and hypermagnesemia (serum level 11.5 mg/dL), after treatment with intravenous magnesium sulfate for preeclampsia in a 24-year-old primigravida at 39 weeks gestation with a previously uncomplicated pregnancy. The symptoms resolved after 4 days of symptomatic treatment in an intensive care unit, and emergency cesarian delivery of a healthy infant (112785).
Ocular/Otic ...Intravenously, magnesium may cause blurred vision (114681). Additionally, cases of visual impairment or nystagmus have been reported following magnesium supplementation, but these events are rare (18111,60818).
Psychiatric ...A case of delirium due to hypermagnesemia has been reported for a patient receiving intravenous magnesium sulfate for pre-eclampsia (60780).
Pulmonary/Respiratory ...Intravenously, magnesium may cause respiratory depression and tachypnea when used in toxic doses (12589,61028,61180).
Other ...Hypothermia from magnesium used as a tocolytic has been reported (60818).
General
...Orally, maitake mushroom is generally well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal effects, including diarrhea and epigastric pain.
Dermatologic ...In a clinical trial, one patient experienced rash and pruritus after two doses of maitake mushroom polysaccharide extract. The allergic reaction cleared without intervention (61239).
Gastrointestinal ...In clinical research of a polysaccharide extract from maitake mushroom, one patient reported nausea (61239) and 2 out of 26 reported epigastric pain (17131). In a clinical trial of a liquid extract from maitake mushroom, 2 out of 21 patients experienced diarrhea, and one experienced nausea. One patient withdrew from the study due to diarrhea (92843).
Immunologic ...In a clinical trial of a liquid extract from maitake mushroom, 4 out of 21 patients experienced eosinophilia (92843).
Musculoskeletal ...In a clinical trial of a polysaccharide extract from maitake mushroom, one patient reported joint swelling (61239).
Pulmonary/Respiratory ...There is one case of occupational hypersensitivity pneumonitis (HP) caused by maitake mushroom spores (61228).
General ...No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
General
...Orally, reishi mushroom is generally well tolerated.
Most Common Adverse Effects:
Orally: Dizziness, dry mouth, itching, nausea, rash, and stomach upset.
Dermatologic ...Orally, reishi mushroom can cause itching, rash, and other skin reactions (12,5479).
Gastrointestinal ...Orally, reishi mushroom can cause dryness of the mouth, throat, or nasal cavity, nausea, stomach upset, and, more rarely, diarrhea (12,70779,91438,108309).
Hematologic ...Orally, reishi mushroom can cause nosebleed and bloody stools (12,91438).
Hepatic ...One case of hepatotoxicity and one case of fatal fulminant hepatitis have been reported in patients who had used reishi mushroom powder for 1-2 months (70766). There is a case report of a 61-year-old male with hypereosinophilia associated with hepatic nodules following the use of reishi mushroom powder for about 2 months. Symptoms resolved after discontinuation of the product. Although these side effects were thought to be associated with the use of reishi mushroom powder, it is unclear if other factors played a role. The patient had been taking tegafur, gimeracil, and oteracil potassium for about 4 months following anterior resection for rectal adenocarcinoma but discontinued these agents and initiated reishi mushroom due to liver injury (108312).
Neurologic/CNS ...Orally, reishi mushroom can cause dizziness (91438). Other rare symptoms include insomnia and headache (70776,70779).
Pulmonary/Respiratory ...Respiratory allergy to reishi spores can occur (12,5479). Sore throat and runny nose have also been reported (70776,91438).
General
...Orally, topically, and when inhaled, sage seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, agitation, diarrhea, dizziness, nausea, and vomiting.
Topically: Burning, dermatitis, pain.
Serious Adverse Effects (Rare):
Orally: Generalized tonic-clonic seizures associated with the thujone, camphor, and/or cineol constituents.
Cardiovascular ...By inhalation, sage essential oil has been reported to increase the blood pressure of hypertensive patients (10334).
Dermatologic
...Orally, sage extract has been reported to cause acneiform skin eruptions in one patient in a clinical trial (91970).
Topically, sage leaves can cause contact dermatitis (46902,72661,72710). Sage extract can cause burning and pain (10437).
Gastrointestinal
...Orally, sage can cause nausea, vomiting, abdominal pain, and diarrhea (10810,17177).
Topically, sage extract sprayed into the mouth and throat can cause dryness or mild burning of the throat (72619).
Neurologic/CNS ...Orally, sage can cause dizziness or agitation (10810,17177). Thujone, a constituent of common sage (Salvia officinalis), is a neurotoxin and can cause seizures (10812,12868). Camphor and cineol, constituents of common sage and Spanish sage, can also cause neurotoxicity and seizures in high doses (10334,12868). Generalized tonic-clonic seizures have been reported in adults, children, and infants after ingestion of sage oil (12868,72666).
Pulmonary/Respiratory
...Orally, sage can cause wheezing (10810,17177).
Occupational exposure to sage dust can cause reduction in ventilatory capacity and chronic respiratory impairment (72672,72682,72686).
General
...Orally, shiitake mushroom is generally well tolerated when cooked and consumed as a food.
Most Common Adverse Effects:
Orally: Abdominal discomfort, bloating, diarrhea, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Consumption of raw shiitake mushroom can cause shiitake dermatitis, a skin eruption resembling whiplash marks which can be accompanied by systemic symptoms. Large pieces that have been inadequately chewed can cause intestinal blockage, occasionally requiring surgery.
Dermatologic
...Orally, shiitake mushrooms can cause shiitake dermatitis, a skin eruption that resembles whiplash marks, usually found on the trunk and limbs.
This dermatitis is thought to be a toxic response to lentinan or other compounds found normally in uncooked or inadequately cooked shiitake mushroom. The rash can be made worse by scratching. Symptom onset is usually within hours to days and can persist for 3-4 weeks before resolving on its own. There is some evidence that treatment with steroids alone or with antihistamines might reduce the duration of the rash by a small amount in some people (1148,1152,74782,74806,94236,94237,94238,94240,94241,94243) (94244,94246,94247,94248,94249,94252,94253,94254,94255,94256)(94257,94259,94261,94262,108302,111909,111912,111913). The dermatitis may include small purple spots from broken capillaries, skin plaques, burning, blanching, and pustules (94256,108302). Rarely the rash may look like measles rather than whiplash (94256). Histologically, there may be evidence of dermal and epidermal edema, lymphocyte infiltration, and skin thickening (94256,94257). Other symptoms associated with the dermatitis include fever, aching, malaise, eosinophilia, diarrhea, prickling in the hands, trouble swallowing, conjunctivitis, and pustules with small ulcers in the mouth (94240,94246,94247,94249,94256,94257,108302). It is likely that the dermatitis and other symptoms are due to a delayed type hypersensitivity reaction (94244,94255). Cooking shiitake mushroom generally prevents shiitake dermatitis, although some cases have occurred in people who have consumed cooked sources (94242,94244). It appears that to inactivate lentinan, cooking temperatures of at least 130°C are needed (94243).
Less common is a photosensitivity reaction associated with oral ingestion, which involves rash and pruritus after sun exposure (1148,94241).
Orally, the shiitake mushroom extract AHCC has been reported to cause mild itching (30375).
Gastrointestinal
...Orally, shiitake mushrooms can cause abdominal discomfort, including bloating, nausea, pain, vomiting, and diarrhea (1149,30365,30375,30419,94241).
Gastrointestinal symptoms, such as diarrhea, problems swallowing, or mouth ulcers have been associated with shiitake dermatitis (94241,94256). Consumption of large pieces of shiitake mushroom with inadequate chewing can cause abdominal obstruction that has resulted in death in one case and surgical intervention in two others. In another case, parenteral nutrition was used exclusively until the shiitake mushroom pieces were passed (1147,94260,103160,108303,108304).
Topically, an oral rinse containing shiitake mushroom extract has been associated with teeth sensitivity, teeth staining, and burning in the mouth (94250).
Hematologic ...Ingestion of shiitake mushroom powder 4 grams daily for 10 weeks caused eosinophilia in 5 of 10 healthy humans (1149). Eosinophilia, and leukocytosis or leukopenia have been reported with shiitake dermatitis (94254,94256,94257).
Immunologic ...Allergic contact dermatitis can occur by contact with shiitake hyphae (filaments) (1153,74785,111913). It appears to be more common in growers or others that handle shiitake mushrooms extensively (94241,94259). Contact or inhalation also results in other symptoms of allergy, such as asthma, rhinitis, conjunctivitis, and pneumonia (94241,94249,94258,94259).
Musculoskeletal ...Orally, the shiitake mushroom extract AHCC has been reported to cause foot cramps and difficulty moving hand joints (30365,30416).
Neurologic/CNS
...In patients experiencing shiitake dermatitis, other symptoms may include prickling in the hands (94256).
Malaise has also been reported following oral intake or contact (1151,94240).
Orally, the shiitake mushroom extract AHCC has been reported to cause mild and transient headache (30365).
Ocular/Otic ...Conjunctivitis has been reported rarely in mushroom growers and handlers, or following oral intake in patients with shiitake dermatitis (94241,94256,94259).
Pulmonary/Respiratory ...In mushroom workers, hypersensitivity pneumonitis due to shiitake spore inhalation has occurred. Symptoms include difficulty breathing, chest pain, a dry cough, asthma, and rhinitis (1150,1151,74776,74813,94239,94241,94258,94259).
General
...Orally, tribulus seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Cases of liver and kidney injury, seizures, and chronic painful erection with impaired sexual function have been reported. Pneumothorax and bronchial polyp after consuming the spine-covered tribulus fruit have been reported.
Gastrointestinal ...Orally, tribulus can cause abdominal pain, cramping, nausea, vomiting, diarrhea, and constipation (92022,92027). However, in one study, the rates of these gastrointestinal complaints were similar for patients taking tribulus and those receiving placebo (92022).
Genitourinary ...In one case report, a patient taking two tribulus tablets (unknown dose) daily for 15 days presented to the local emergency department with a painful erection lasting 72 hours. The priapism was resolved with medical management; however, post-episode sexual function was impaired (92023).
Hepatic ...In one case report, a patient drinking tribulus water 2 liters daily for two days presented with lower limb weakness, seizures, hepatitis, and acute kidney injury. The patient's condition improved after hemodialysis and discontinuation of tribulus water (92069).
Neurologic/CNS ...Orally, tribulus has been reported to cause general excitation and insomnia. These symptoms were reversed upon discontinuation of the drug or decreasing the dose (78867). In one case report, a patient drinking tribulus water 2 liters daily for two days presented with lower limb weakness, seizures, hepatitis, and acute kidney injury. The patient's condition improved after hemodialysis and discontinuation of tribulus water (92069).
Pulmonary/Respiratory ...In one case report, a patient developed a bilateral pneumothorax after consuming the spine-covered fruit of tribulus (818). In another case report, a patient developed a polyp in the lobar bronchus of the right interior lobe due to the presence of a tribulus fruit spine (78852).
Renal ...In one case report, a patient drinking tribulus water 2 liters daily for two days presented with lower limb weakness, seizures, hepatitis, and acute kidney injury. The patient's condition improved after hemodialysis and discontinuation of the tribulus water (92069). In another case report, a healthy male taking one tribulus tablet (unknown dose) daily for a few months for bodybuilding purposes developed hyperbilirubinemia followed by acute kidney failure 2-3 weeks later. The patient was managed with intravenous fluids and a low-salt, low-protein diet (92025).
Other ...In one case report, gynecomastia was observed in a male weightlifter taking an herbal combination product containing tribulus. However, it is not clear if this adverse effect can be attributed to tribulus alone (78859).
General
...Orally, zinc is well tolerated in doses below the tolerable upper intake level (UL), which is 40 mg daily for adults.
Topically, zinc is well tolerated.
Most Common Adverse Effects:
Orally: Abdominal cramps, diarrhea, metallic taste, nausea and vomiting (dose-related).
Topically: Burning, discoloration, itching, stinging, and tingling when applied to irritated tissue.
Intranasally: Bad taste, dry mouth, headache, irritation, reduced sense of smell.
Serious Adverse Effects (Rare):
Orally: There have been cases of acute renal tubular necrosis, interstitial nephritis, neurological complications, severe vomiting, and sideroblastic anemia after zinc overdose.
Intranasally: There have been cases where intranasal zinc caused permanent loss of smell (anosmia).
Dermatologic
...Topically, zinc can cause burning, stinging, itching, and tingling when applied to inflamed tissue (6911,8623,87297).
Zinc oxide can be deposited in the submucosal tissue and cause dark discoloration of the skin. This can occur with prolonged topical application to intact skin, application to eroded or ulcerated skin, or penetrating traumatic exposure, and also parenteral administration (8618).
In rare cases, oral zinc has resulted in worsened acne (104056), skin sensitivity (6592), a leishmanial reaction with a macular rash that occurred on exposed parts of the body (86935), eczema (104055), systemic contact dermatitis (109457), and the development of severe seborrheic dermatitis (86946).
Gastrointestinal
...Orally, zinc can cause nausea (338,2663,2681,6592,6700,18216,106230,106233,106227,113661), vomiting (2663,2681,6519,6592,96069,96074), a metallic or objectionable taste in the mouth (336,338,6700,11350,18216,106902,113661), abdominal cramping (6592,96069), indigestion (87227), heartburn (96069), dry mouth (87533), and mouth irritation (336,2619).
When used orally in amounts above the tolerable upper intake level, zinc may cause irritation and corrosion of the gastrointestinal tract (331,86982,87315,106902), watery diarrhea (1352), epigastric pain (2663,2681), and severe vomiting (2663,2681).
Intranasally, zinc can cause bad taste, dry mouth, and burning and irritation of the throat (8628,8629).
When used topically as a mouth rinse, zinc may cause tooth staining (90206).
Hematologic ...There is concern that high daily doses of zinc, above the tolerable upper intake level (UL) of 40 mg per day, might increase the risk of copper deficiency, potentially leading to anemia and leukopenia (7135,112473). To prevent copper deficiency, some clinicians give a small dose of copper when zinc is used in high doses, long-term (7303).
Hepatic ...There are two cases of liver deterioration in patients with Wilson disease following initiation of treatment with zinc 50-200 mg three times daily. The mechanism of action is not understood, and the event is extremely uncommon (86927,87470).
Immunologic ...Daily doses of 300 mg of supplemental zinc for 6 weeks appear to impair immune response (7135). A case of erythematosus-like syndrome, including symptoms such as fever, leg ulcers, and rash, has been reported following intake of effervescent tablets (Solvezink) containing zinc 45 mg (87506). In another case, severe neutropenia was reported after taking supplemental zinc 900 mg daily for an unknown duration (112473).
Musculoskeletal ...Orally, zinc may cause body aches in children (113661).
Neurologic/CNS
...Zinc-containing denture adhesives can cause toxicity if used more frequently than recommended for several years.
Case reports describe hyperzincemia, low copper levels, blood dyscrasias, and neurological problems, including sensory disturbances, numbness, tingling, limb weakness, and difficulty walking in patients applying denture adhesive multiple times daily for several years (17092,17093,90205,90233). Due to reports of zinc toxicity associated with use of excessive amounts of zinc-containing denture adhesives for several years, GlaxoSmithKline has reformulated Polygrip products to remove their zinc content (17092,17093).
Intranasally (8628) and orally (87534), zinc can cause headache. When used orally in amounts above the tolerable upper intake level (UL), zinc may cause central nervous system (CNS) symptoms including lethargy, fatigue, neuropathy, dizziness, and paresthesia (2663,2681,87369,87470,87533,87534,112473).
Oncologic ...There is concern that zinc might worsen prostate disease. For example, some preliminary evidence suggests that higher dietary zinc intake increases the risk for benign prostatic hyperplasia (6908). Epidemiological evidence suggests that taking more than 100 mg of supplemental zinc daily or taking supplemental zinc for 10 or more years doubles the risk of developing prostate cancer (10306). Another large-scale population study also suggests that men who take a multivitamin more than 7 times per week and who also take a separate zinc supplement have a significantly increased risk of prostate cancer-related mortality (15607). However, a large analysis of population research suggests that there is no association between zinc intake and the risk of prostate cancer (96075).
Pulmonary/Respiratory
...There are several hundred reports of complete loss of sense of smell (anosmia) that may be permanent with use of zinc gluconate nasal gel, such as Zicam (11306,11155,11707,16800,16801,17083,86999,87535).
Loss of sense of smell is thought to be dose related but has also been reported following a single application (11306,11155,11707,16800). Patients often report having sniffed deeply when applying the gel, then experiencing an immediate burning sensation, and noticing anosmia within 48 hours (17083). On June 16, 2009, the US Food and Drug Administration (FDA) advised patients not to use a specific line of commercial zinc nasal products (Zicam) after receiving 130 reports of loss of smell (16800). The manufacturer of these products had also received several hundred reports of loss of smell related to its intranasal zinc products (16801). Zinc sulfate nasal spray was used unsuccessfully for polio prophylaxis before the polio vaccine was developed. It caused loss of smell and/or taste, which was sometimes permanent (11713). Animal studies suggest that zinc sulfate negatively affects smell, possibly by damaging the olfactory epithelium and neurons (11156,11703,11704,11705,11706). Zinc gluconate nasal spray has not been tested for safety in animals or humans. The clinical studies of intranasal zinc have not described anosmia as an adverse effect, but testing was not done to see if zinc use adversely affected sense of smell (6471,8628,8629,10247). Also, these clinical studies reported tingling or burning sensation in the nostril, dry nose, nose pain, and nosebleeds.
When used in amounts above the tolerable upper intake level (UL), zinc may cause flu-like symptoms including coughing (2663).
Renal ...In overdose, zinc can cause acute renal tubular necrosis and interstitial nephritis (331,1352,87338).
Other ...Occupational inhalation of zinc oxide fumes can cause metal fume fever with symptoms including fatigue, chills, fever, myalgias, cough, dyspnea, leukocytosis, thirst, metallic taste, and salivation (331).
