Below is general information about the safety of the known ingredients contained in the product Organic Seven Treasures Mushroom Powder. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
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 chaga.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. For people age 14 and older with adequate iron stores, iron supplements are safe when used in doses below the tolerable upper intake level (UL) of 45 mg per day of elemental iron. The UL is not meant to apply to those who receive iron under medical supervision (7135,96621). To treat iron deficiency, most people can safely take up to 300 mg elemental iron per day (15). ...when used intravenously and appropriately. Ferric carboxymaltose 200 mg and iron sucrose 200 mg have been given intravenously for up to 10 doses with no reported serious adverse effects (91179). A meta-analysis of clinical studies of hemodialysis patients shows that administering high-dose intravenous (IV) iron does not increase the risk of hospitalization, infection, cardiovascular events, or death when compared with low-dose IV iron, oral iron, or no iron treatment (102861). A more recent meta-analysis of clinical studies of all patient populations shows that administering IV iron does not increase the risk of hospital length of stay or mortality, although the risk of infection is increased by 16% when compared with oral iron or no iron (110186). Another meta-analysis of 3 large clinical trials in patients with heart failure shows that IV ferric carboxymaltose at a dose of around 1500 mg every 6 months for a year does not increase the incidence of adverse effects when compared with placebo (113901). Despite these findings, there are rare reports of hypophosphatemia and/or osteomalacia (112603,112608,112609,112610,113905).
LIKELY UNSAFE ...when used orally in excessive doses. Doses of 30 mg/kg are associated with acute toxicity. Long-term use of high doses of iron can cause hemosiderosis and multiple organ damage. The estimated lethal dose of iron is 180-300 mg/kg; however, doses as low as 60 mg/kg have also been lethal (15).
CHILDREN: LIKELY SAFE
when used orally and appropriately (7135,91183,112601).
CHILDREN: LIKELY UNSAFE
when used orally in excessive amounts.
Tell patients who are not iron-deficient not to use doses above the tolerable upper intake level (UL) of 40 mg per day of elemental iron for infants and children aged 0-13 years and 45 mg per day for children aged 14-18 years. Higher doses frequently cause gastrointestinal side effects such as constipation and nausea (7135,20097). Iron is the most common cause of pediatric poisoning deaths. Doses as low as 60 mg/kg can be fatal (15).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Iron is safe during pregnancy and breast-feeding in patients with adequate iron stores when used in doses below the tolerable upper intake level (UL) of 45 mg daily of elemental iron (7135,96625,110180).
PREGNANCY AND LACTATION: LIKELY UNSAFE
when used orally in high doses.
Tell patients who are not iron deficient to avoid exceeding the tolerable upper intake level (UL) of 45 mg daily of elemental iron. Higher doses frequently cause gastrointestinal side effects such as nausea and vomiting (7135) and might increase the risk of preterm labor (100969). High hemoglobin concentrations at the time of delivery are associated with adverse pregnancy outcomes (7135,20109).
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).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in doses up to 100 mEq total potassium daily, not to exceed 200 mEq in a 24-hour period (95010,107989). Oral potassium chloride and potassium citrate are FDA-approved prescription products (95010,107989). Larger doses increase the risk of hyperkalemia (15). ...when administered intravenously (IV) at appropriate infusion rates (95011). Parenteral potassium is an FDA-approved prescription product (15,95011). A tolerable upper intake level (UL) for potassium has not been established; however, potassium levels should be monitored in individuals at increased risk for hyperkalemia, such as those with kidney disease, heart failure, and adrenal insufficiency (100310,107966).
CHILDREN: LIKELY SAFE
when used orally and appropriately in dietary amounts.
A tolerable upper intake level (UL) has not been established for healthy individuals (6243,100310).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in dietary amounts of 40-80 mEq daily (15).
A tolerable upper intake level (UL) has not been established for healthy individuals (100310).
POSSIBLY SAFE ...when an extract of reishi mushroom is used orally and appropriately for up to one year (12,5485,70767,70774,70786,70799,70800,70801,70802). ...when whole powdered reishi mushroom is used orally and appropriately for up to 16 weeks (70776,70799,70800,70801,91433,91435,91436,91437,108309).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using
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 SAFE ...when used orally and appropriately. Sodium is safe in amounts that do not exceed the Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams daily (100310). Higher doses can be safely used therapeutically with appropriate medical monitoring (26226,26227).
POSSIBLY UNSAFE ...when used orally in high doses. Tell patients to avoid exceeding the CDRR intake level of 2.3 grams daily (100310). Higher intake can cause hypertension and increase the risk of cardiovascular disease (26229,98176,98177,98178,98181,98183,98184,100310,109395,109396,109398,109399). There is insufficient reliable information available about the safety of sodium when used topically.
CHILDREN: LIKELY SAFE
when used orally and appropriately (26229,100310).
Sodium is safe in amounts that do not exceed the CDRR intake level of 1.2 grams daily for children 1 to 3 years, 1.5 grams daily for children 4 to 8 years, 1.8 grams daily for children 9 to 13 years, and 2.3 grams daily for adolescents (100310).
CHILDREN: POSSIBLY UNSAFE
when used orally in high doses.
Tell patients to avoid prolonged use of doses exceeding the CDRR intake level of 1.2 grams daily for children 1 to 3 years, 1.5 grams daily for children 4 to 8 years, 1.8 grams daily for children 9 to 13 years, and 2.3 grams daily for adolescents (100310). Higher intake can cause hypertension (26229).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Sodium is safe in amounts that do not exceed the CDRR intake level of 2.3 grams daily (100310).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in higher doses.
Higher intake can cause hypertension (100310). Also, both the highest and the lowest pre-pregnancy sodium quintile intakes are associated with an increased risk of hypertensive disorders of pregnancy, including gestational hypertension and pre-eclampsia, and the delivery of small for gestational age (SGA) infants when compared to the middle intake quintile (106264).
LIKELY SAFE ...when turkey tail mushroom is used orally and appropriately (5477). ...when polysaccharide krestin (PSK) and polysaccharide peptide (PSP) isolates of turkey tail mushroom are used orally and appropriately (1635,1636,1640,1641,1648,1649,1650,1651,1652,1653,1654) (1655,1656,1657,1658,1659,1660,1661,1662,70167,70168,70171,70188,70200,94076). There is insufficient reliable information available about the safety of turkey tail mushroom when used topically or intravaginally.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally or intramuscularly and appropriately. Vitamin D has been safely used in a wide range of doses (7555,16888,16891,17476,95913,98186,104619,105209,109040,109059)(115580,115590). When used orally long-term, doses should not exceed the tolerable upper intake level (UL) of 4000 IU (100 mcg) daily for adults (17506,99773); however, much higher doses such as 50,000 IU (1250 mcg) weekly orally for 6-12 weeks are often needed for the short-term treatment of vitamin D deficiency (16891,17476,115590). Monthly oral doses of up to 60,000 IU (1500 mcg) have also been safely used for up to 5 years (105726). Toxicity usually does not occur until plasma levels exceed 150 ng/mL (17476).
POSSIBLY UNSAFE ...when used orally in excessive doses, long-term. Taking doses greater than the tolerable upper intake level (UL) of 4000 IU (100 mcg) daily for adults for long periods can increase the risk of hypercalcemia (17506); however, much higher doses are often needed for short-term treatment of vitamin D deficiency. Toxicity typically occurs when levels exceed 150 ng/mL (17476).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
When used long-term, doses should not exceed the tolerable upper intake level (UL) of 1000 IU (25 mcg) daily for those 0-6 months of age, 1500 IU (37.5 mcg) daily for those 6-12 months of age, 2500 IU (62.5 mcg) daily for those 1-3 years of age, 3000 IU (75 mcg) daily for those 4-8 years of age, and 4000 IU (100 mcg) daily for those 9 years and older (17506); however, much higher doses are often needed for the short-term treatment of vitamin D deficiency. Some research shows that giving vitamin D 14,000 IU (350 mcg) weekly for a year in children aged 10-17 years is safe (16875). A meta-analysis of clinical studies shows that 1000 IU (25 mcg) daily in those up to a year of age and greater than 2000 IU (50 mcg) daily in those aged 1-6 years does not increase the risk of serious adverse events (108424).
CHILDREN: POSSIBLY UNSAFE
when used orally in excessive doses for longer than one year.
Taking doses greater than the tolerable upper intake level (UL) long-term can increase the risk of hypercalcemia (17506).
PREGNANCY: LIKELY SAFE
when used orally and appropriately.
Vitamin D is safe when used in doses below the tolerable upper intake level (UL) of 4000 IU (100 mcg) daily (17506,95910).
PREGNANCY: POSSIBLY UNSAFE
when used orally in excessive amounts.
Tell patients not to use doses above the tolerable upper intake level (UL) of 4000 IU (100 mcg) daily. Hypercalcemia during pregnancy due to excessive vitamin D intake can lead to several fetal adverse effects, including suppression of parathyroid hormone, hypocalcemia, tetany, seizures, aortic valve stenosis, retinopathy, and mental and/or physical developmental delay (17506).
LACTATION: LIKELY SAFE
when used orally and appropriately.
Vitamin D is safe when used in doses below the tolerable upper intake level (UL) of 4000 IU (100 mcg) daily (17506).
LACTATION: POSSIBLY UNSAFE
when used orally in excessive amounts.
Tell patients not to use doses above the tolerable upper intake level (UL) of 4000 IU (100 mcg) daily (17506).
Below is general information about the interactions of the known ingredients contained in the product Organic Seven Treasures Mushroom Powder. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
 Details
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, chaga may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
In vitro and animal research suggests that chaga extract can inhibit platelet aggregation (26260). This effect has not been reported in humans.
|
Theoretically, taking chaga with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, chaga might interfere with immunosuppressive therapy.
Details
In vitro research suggests that certain constituents of chaga stimulate immune function (26263). This has not been reported in humans.
|
Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Details
|
Theoretically, concurrent use of cordyceps might interfere with immunosuppressive therapy.
Details
Animal and in vitro research suggests that cordyceps stimulates the immune system (3403,3404,3414,3431,3432). However, limited clinical research suggests that taking cordyceps may lower the necessary therapeutic dose of the immunosuppressant cyclosporine (92828), which suggests that cordyceps may have an immunosuppressive effect.
|
Theoretically, concurrent use of cordyceps and testosterone might have additive effects.
Details
Animal research suggests that cordyceps can increase testosterone levels (46087). The clinical significance of this finding is unclear.
|
Iron reduces the absorption of bisphosphonates.
Details
Advise patients that doses of bisphosphonates should be separated by at least two hours from doses of all other medications, including supplements such as iron. Divalent cations, including iron, can decrease absorption of bisphosphonates by forming insoluble complexes in the gastrointestinal tract (15).
|
Theoretically, taking chloramphenicol with iron might reduce the response to iron therapy in iron deficiency anemia.
Details
|
Administration of intravenous iron within one month of denosumab administration might increase the risk of severe hypophosphatemia and hypocalcemia.
Details
A case of severe hypocalcemia (albumin corrected calcium 6.88 mg/dL, ionized calcium 3.68 mg/dL) and hypophosphatemia (<0.5 mg/dL) with respiratory acidosis, QT interval prolongation, and nonsustained ventricular tachycardia was reported in a 76-year-old male who had received an iron polymaltose infusion within 2 weeks of a subcutaneous injection of denosumab. Serum parathyroid hormone was also elevated (348 pg/mL). Subsequent iron infusions with iron polymaltose and ferric carboxymaltose were followed by transient hypophosphatemia, but without hypocalcemia. Additionally, a literature review describes 6 additional cases of hypophosphatemia and hypocalcemia in patients 52-92 years of age who had been administered intravenous iron as either ferric carboxymaltose or iron polymaltose and subcutaneous denosumab within 1-4 weeks of each other (113905).
|
Iron might decrease dolutegravir levels by reducing its absorption.
Details
Advise patients to take dolutegravir at least 2 hours before or 6 hours after taking iron. Pharmacokinetic research shows that iron can decrease the absorption of dolutegravir from the gastrointestinal tract through chelation (93578). When taken under fasting conditions, a single dose of ferrous fumarate 324 mg orally along with dolutegravir 50 mg reduces overall exposure to dolutegravir by 54% (94190).
|
Theoretically, taking iron along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Details
Iron is a divalent cation. There is concern that iron may decrease the absorption of integrase inhibitors from the gastrointestinal tract through chelation (93578). One pharmacokinetic study shows that iron can decrease blood levels of the specific integrase inhibitor dolutegravir through chelation (94190). Also, other pharmacokinetic research shows that other divalent cations such as calcium can decrease the absorption and levels of some integrase inhibitors through chelation (93578,93579).
|
Iron might decrease levodopa levels by reducing its absorption.
Details
Advise patients to separate doses of levodopa and iron as much as possible. There is some evidence in healthy people that iron forms chelates with levodopa, reducing the amount of levodopa absorbed by around 50% (9567). The clinical significance of this hasn't been determined.
|
Iron might decrease levothyroxine levels by reducing its absorption.
Details
Advise patients to separate levothyroxine and iron doses by at least 2 hours. Iron can decrease the absorption and efficacy of levothyroxine by forming insoluble complexes in the gastrointestinal tract (9568).
|
Iron might decrease methyldopa levels by reducing its absorption.

Theoretically, iron might decrease mycophenolate mofetil levels by reducing its absorption.
Details
Advise patients to take iron 4-6 hours before, or 2 hours after, mycophenolate mofetil. It has been suggested that a decrease of absorption is possible, probably by forming nonabsorbable chelates. However, mycophenolate pharmacokinetics are not affected by iron supplementation in available clinical research (3046,20152,20153,20154,20155).
|
Iron might decrease penicillamine levels by reducing its absorption.
Details
Advise patients to separate penicillamine and iron doses by at least 2 hours. Oral iron supplements can reduce absorption of penicillamine by 30% to 70%, probably due to chelate formation. In people with Wilson's disease, this interaction has led to reduced efficacy of penicillamine (3046,3072,20156).
|
Iron might decrease levels of quinolone antibiotics by reducing their absorption.
Details
|
Iron might decrease levels of tetracycline antibiotics by reducing their absorption.
Details
Advise patients to take iron at least 2 hours before or 4 hours after tetracycline antibiotics. Concomitant use can decrease absorption of tetracycline antibiotics from the gastrointestinal tract by 50% to 90% (15).

Theoretically, lion's mane mushroom may increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
Details
In vitro research suggests that lion's mane mushroom extracts can inhibit platelet aggregation (92619).
|
Theoretically, lion's mane mushroom may have additive effects when used with antidiabetes drugs.
Details
Animal research suggests that an aqueous extract of lion's mane mushroom can reduce serum glucose and increase serum insulin (91996).
|
Theoretically, concurrent use of lion's mane mushroom might interfere with immunosuppressive therapy.
Details
|
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).
|
Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
Details
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion (95628). Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia (15,23207). However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels (95628).
|
Using ARBs with high doses of potassium increases the risk of hyperkalemia.
Details
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion (95628). Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia (15,23207). However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels (95628).
|
Concomitant use increases the risk of hyperkalemia.
Details
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia (15).

Theoretically, shiitake mushroom might decrease levels of drugs metabolized by CYP2D6.
Details
|
Theoretically, taking shiitake mushroom might decrease the effects of immunosuppressive therapy.
Details
|
Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
Details
|
Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Details
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone (4425).
|
Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
Details
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion (26225). Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate (26224,26225). Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L (112909). Patients taking lithium should avoid significant alterations in their dietary intake of sodium.
|
Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
Details
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population (100310). Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.
|
Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Details
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia (29406). Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.
|
Theoretically, taking turkey tail mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might increase exposure to cyclophosphamide.
Details
Some animal research shows that the PSP component of turkey tail mushroom can increase the area under the concentration-time curve (AUC) of cyclophosphamide by 44% to 50% and the half-life by 34% to 43% (96569). This interaction could potentially increase the effects and adverse effects of cyclophosphamide. However, it is not known whether PSP affects the levels of the active metabolites of cyclophosphamide that are responsible for its clinical activity.
|
Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might inhibit CYP2C9.
Details
Laboratory research suggests that the PSP component of turkey tail mushroom dose-dependently inhibits CYP2C9 (94075). Theoretically, taking PSP with drugs metabolized by CYP2C9 might increase drug levels and the risk of adverse effects. However, this has not been reported in humans.
|
Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might interfere with the absorption of tamoxifen.
Details
Animal research suggests that PSP increases the time to reach maximum concentration of a single dose of tamoxifen by about 9.5 hours, or 228%. When repeated doses of tamoxifen were given, the time to reach maximum concentration was increased by about 5.6 hours, or 93%. However, PSP did not affect the maximum concentration or the area under the curve of tamoxifen (108308).
|
Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
Details
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption (11595,11597,22916). This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically (11529,11596,11597).
|
Vitamin D might reduce absorption of atorvastatin.
Details
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change (16828). Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.
|
Taking calcipotriene with vitamin D increases 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 (15). Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.
|
Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
Details
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found (110539). A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced (16828). While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.
|
Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
Details
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin (15). Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.
|
Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
Details
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation (10574). Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.
|
Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Details
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently (3072,11541,69580). This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily (11539,11540).
|
Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Details
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation (10574). Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.

Below is general information about the adverse effects of the known ingredients contained in the product Organic Seven Treasures Mushroom Powder. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
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 ...There is limited reliable information available regarding the adverse effects of chaga.
Renal ...Orally, there have been two cases of kidney failure and one case of acute nephropathy related to excessive chaga consumption, which contains high concentrations of oxalate (96566,105246,108756).
General
...Orally, cordyceps seems to be generally well tolerated when used for up to 1 year.
Most Common Adverse Effects:
Orally: Abdominal discomfort, constipation, diarrhea.
Gastrointestinal ...Orally, cordyceps has been associated with diarrhea, constipation, abdominal discomfort, dry mouth, and throat discomfort in clinical research. However, these events were uncommon, and in some cases symptoms could be reduced by taking cordyceps after eating (92829,105076,109705).
Hematologic ...Two cases of lead poisoning, characterized by loss of appetite and other symptoms, have been reported for patients taking cordyceps powder. After discontinuing cordyceps supplementation, both patients were treated with chelating agents (46135).
Hepatic ...There is a case report of acute cholestatic hepatitis probably associated with the use of a product containing cordyceps. The 64-year-old male was asymptomatic except for jaundice and laboratory markers and recovered once the supplement was stopped. However, it is unclear whether the hepatitis is associated with the cordyceps or with an unknown contaminant (109704).
Renal ...One case of a mild increase in serum creatinine level (< 30%) has been reported (95905).
General
...Orally or intravenously, iron is generally well tolerated when used appropriately.
Most Common Adverse Effects:
Orally: Abdominal pain, constipation, diarrhea, gastrointestinal irritation, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about oral or gastric ulcerations.
Intravenously: Case reports have raised concerns about hypophosphatemia and osteomalacia.
Cardiovascular
...There is debate regarding the association between coronary heart disease (CHD) or myocardial infarction (MI) and high iron intake or high body iron stores.
Some observational studies have reported that high body iron stores are associated with increased risk of MI and CHD (1492,9542,9544,9545,15175). Some observational studies reported that only high heme iron intake from dietary sources such as red meat are associated with increased risk of MI and CHD (1492,9546,15174,15205,15206,91180). However, the majority of research has found no association between serum iron levels and cardiovascular disease (1097,1099,9543,9547,9548,9549,9550,56469,56683).
There is one case of Kounis syndrome, also referred to as allergic angina or allergic myocardial infarction, in a 39-year-old female patient without previous coronary artery disease given intravenous ferric carboxymaltose. The patient experienced anaphylactic symptoms, including headache, abdominal pain, and breathing difficulties, 3 minutes after starting the infusion. She was further diagnosed with non-ST-elevation myocardial infarction (112607).
There is also a case of a 56-year-old female, negative for HFE mutation homozygosity, diagnosed with acquired iron overload cardiomyopathy after starting ferrous sulfate 325 mg twice daily 3 years prior for iron deficiency secondary to alcoholic cirrhosis with esophageal varices and encephalopathy. The patient had no follow-up care over the 3 years and denied any blood transfusions over that time (113906).
Dermatologic ...Cutaneous hemosiderosis, or skin staining, has been reported following intravenous (IV) iron infusion in various case reports. Most of these cases are due to extravasation following iron infusion (112605,112611). In one case, extravasation has occurred following iron derisomaltose infusion in a 41-year-old female with chronic kidney disease (112605). Rarely, diffuse cutaneous hermosiderosis has occurred. In one case, a 31-year-old female with excessive sweating developed cutaneous hemosiderosis in the armpits following an (IV) iron polymaltose infusion (112611).
Endocrine
...Population research in females shows that higher ferritin levels are associated with an approximately 1.
5-fold higher odds of developing gestational diabetes. Increased dietary intake of heme-iron, but not non-heme iron, is also associated with an increased risk for gestational diabetes. The effects of iron supplementation could not be determined from the evaluated research (96618). However, in a sub-analysis of a large clinical trial in pregnant adults, daily supplementation with iron 100 mg from 14 weeks gestation until delivery did not affect the frequency or severity of glucose intolerance or gestational weight gain (96619).
Intravenous (IV) iron may trigger hypophosphatemia in some patients (113905). A meta-analysis of clinical studies in adults with iron deficiency anemia shows that IV ferric carboxymaltose is associated with a higher risk of hypophosphatemia when compared with other IV formulations (i.e. iron dextran, iron isomaltoside, iron sucrose, and ferumoxytol) (115899). Severe hypophosphatemia requiring IV phosphate has also occurred following IV ferric carboxymaltose (112608,112610).
Additionally, cases of osteomalacia related to hypophosphatemia subsequent to parenteral iron administration have been rarely reported (112603,112609).
Gastrointestinal
...Orally, iron can cause dry mouth, gastrointestinal irritation, heartburn, abdominal pain, constipation, diarrhea, nausea, or vomiting (96621,102864,104680,104684,110179,110185,110188,110189,110192,115894).
These adverse effects are uncommon at doses below the tolerable upper intake level (UL) of 45 mg per day of elemental iron in adults with normal iron stores (7135). Higher doses can be taken safely in adults with iron deficiency, but gastrointestinal side effects may occur (1095,20118,20119,56698,102864). Taking iron supplements with food seems to reduce gastrointestinal side effects (7135). However, food can also significantly reduce iron absorption. Iron should be taken on an empty stomach, unless it cannot be tolerated.
There are several formulations of iron products such as ferrous sulfate, ferrous gluconate, ferrous fumarate, and others. Manufacturers of some formulations, such as polysaccharide-iron complex products (Niferex-150, etc), claim to be better tolerated than other formulations; however, there is no reliable evidence to support this claim. Gastrointestinal tolerability relates mostly to the elemental iron dose rather than the formulation (17500).
Enteric-coated or controlled-release iron formulations might reduce nausea for some patients, however, these products also have lower absorption rates (17500).
Liquid oral preparations can blacken and stain teeth (20118).
Iron can also cause oral ulcerations and ulcerations of the gastric mucosa (56684,91182,96622,110179). In one case report, an 87-year-old female with Alzheimer disease experienced a mucosal ulceration, possibly due to holding a crushed ferrous sulfate 80 mg tablet in the mouth for too long prior to swallowing (91182). The ulceration was resolved after discontinuing iron supplementation. In another case report, a 76-year old male suffered gastric mucosal injury after taking a ferrous sulfate tablet daily for 4 years (56684). In a third case report, a 14-year-old female developed gastritis involving symptoms of upper digestive hemorrhage, nausea, melena, and stomach pain. The hemorrhage was attributed to supplementation with ferrous sulfate 2 hours after meals for the prior 2 weeks (96622). In one case report, a 43-year old female developed atrophic gastritis with non-bleeding ulcerations five days after starting oral ferrous sulfate 325 mg twice daily (110179).
Intravenously, iron can cause gastrointestinal symptoms such as nausea and diarrhea(104684,110192,115894).
Hematologic ...Orally, iron supplements have been associated with hemochromatosis. In one case report, a 56-year-old female, negative for HFE mutation homozygosity, was diagnosed with acquired hemochromatosis after starting ferrous sulfate 325 mg twice daily 3 years prior, without follow-up care, for a previous iron deficiency secondary to alcoholic cirrhosis with esophageal varices and encephalopathy (113906).
Immunologic
...Although there is some clinical research associating iron supplementation with an increased rate of malaria infection (56796,95432), the strongest evidence to date does not support this association, at least for areas where antimalarial treatment is available (95433,96623).
In an analysis of 14 trials, iron supplementation was not associated with an increased risk of malaria (96623). In a sub-analysis of 7 preliminary clinical studies, the effect of iron supplementation was dependent upon the access to services for antimalarial treatment. In areas where anemia is common and services are available, iron supplementation is associated with a 9% reduced risk of clinical malaria. In an area where services are unavailable, iron supplementation was associated with a 16% increased risk in malaria incidence (96623). The difference in these findings is likely associated with the use of malaria prevention methods.
A meta-analysis of clinical studies of all patient populations shows that administering intravenous (IV) iron, usually iron sucrose and ferric carboxymaltose, increases the risk of infection by 16% when compared with oral iron or no iron. However, sub-analyses suggest this increased risk is limited to patients with inflammatory bowel disease (IBD) (110186). Additionally, a meta-analysis in adults with cancer-associated anemia shows that IV iron does not increase the risk of infection when compared with oral iron or no iron therapy (115892).
Intravenously, iron has rarely resulted in allergic reactions, including anaphylactoid reactions (110185,110192,112606,112607). There is one case of Kounis syndrome, also referred to as allergic angina or allergic myocardial infarction, in a 39-year-old female patient without previous coronary artery disease given IV ferric carboxymaltose. The patient experienced anaphylactic symptoms, including headache, abdominal pain, and breathing difficulties, 3 minutes after starting the infusion. She was further diagnosed with non-ST-elevation myocardial infarction (112607).
Musculoskeletal ...Intravenous (IV) iron may trigger hypophosphatemia in some patients, and cases of osteomalacia related to hypophosphatemia subsequent to parenteral iron administration have been rarely reported (112609,113905). In one case, a 70-year-old male with a genetic hemorrhagic disorder infused with ferric carboxymaltose developed lower limb pain with hypophosphatemia and diffuse bone demineralization in the feet (112609). In a second case, a 61-year-old male developed femoral neck insufficiency fractures following repeated ferric carboxymaltose transfusions for anemia related to vascular malformation in the bowel (112603).
Oncologic
...There is a debate regarding the association between high levels of iron stores and cancer.
Data are conflicting and inconclusive (1098,1099,1100,1102). Epidemiological studies suggest that increased body iron stores may increase the risk of cancer or general mortality (56703).
Occupational exposure to iron may be carcinogenic (56691). Oral exposure to iron may also be carcinogenic. Pooled analyses of population studies suggest that increasing the intake of heme iron increases the risk of colorectal cancer. For example, increasing heme iron intake by 1 mg/day is associated with an 11% increase in risk (56699,91185).
Pulmonary/Respiratory ...Orally, iron has been associated with rare reports of iron pill aspiration. This occurs when all or part of the pill is aspirated into the lungs. Once in the lungs, it can cause a chemical burn of the bronchial mucosa. Dozens of cases of iron pill aspiration have been reported in individuals ranging in age from 22 months to 92 years. Patients presented with cough, dyspnea, wheezing, and hemoptysis. The hemoptysis led to death in 2 patients due to hemorrhage. Long-term complication of fibrosis and bronchial stenosis was reported in a few of the cases. In one case, a 48-year-old female accidentally aspirated a ferrous sulfate tablet and presented to the emergency department with cough, blood-stained sputum, chest pain, dyspnea, and acute distress. Bronchoscopy was performed, parts of the pill were retrieved, and chemical burns and necrotic tissue were observed in the bronchus intermedius mucosa and throughout the middle and lower lobes. Debridement with bronchoalveolar lavage was performed. The patient was transferred to the intensive care unit, placed on mechanical ventilation for 2 days, treated with corticosteroids, and discharged on the fifth day of hospitalization. Four weeks post-discharge the patient had significantly improved but still had some reduction in lung capacity.
Other ...Intravenously, sodium ferric gluconate complex (SFGC) caused drug intolerance reactions in 0. 4% of hemodialysis patients including 2 patients with pruritus and one patient each with anaphylactoid reaction, hypotension, chills, back pain, dyspnea/chest pain, facial flushing, rash and cutaneous symptoms of porphyria (56527).

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
...Orally or intravenously, potassium is generally well-tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, belching, diarrhea, flatulence, nausea, and vomiting.
Serious Adverse Effects (Rare):
All ROAs: High potassium levels can cause arrhythmia, heart block, hypotension, and mental confusion.
Cardiovascular ...Orally or intravenously, high potassium levels can cause hypotension, cardiac arrhythmias, heart block, or cardiac arrest (15,16,3385,95011,95626,95630).
Gastrointestinal ...Orally or intravenously, high doses of potassium can cause, nausea, vomiting, abdominal pain, diarrhea, and flatulence (95010,95011). Bleeding duodenal ulcers have also been associated with ingestion of slow-release potassium tablets (69625,69672).
Neurologic/CNS ...Orally or intravenously, high potassium levels can cause paresthesia, generalized weakness, flaccid paralysis, listlessness, vertigo, or mental confusion (15,16,3385,95011).
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, 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, sodium is well tolerated when used in moderation at intakes up to the Chronic Disease Risk Reduction (CDRR) intake level.
Topically, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Worsened cardiovascular disease, hypertension, kidney disease.
Cardiovascular
...Orally, intake of sodium above the CDRR intake level can exacerbate hypertension and hypertension-related cardiovascular disease (CVD) (26229,98176,100310,106263).
A meta-analysis of observational research has found a linear association between increased sodium intake and increased hypertension risk (109398). Observational research has also found an association between increased sodium salt intake and increased risk of CVD, mortality, and cardiovascular mortality (98177,98178,98181,98183,98184,109395,109396,109399). However, the existing research is unable to confirm a causal relationship between sodium intake and increased cardiovascular morbidity and mortality; high-quality, prospective research is needed to clarify this relationship (100312). As there is no known benefit with increased salt intake that would outweigh the potential increased risk of CVD, advise patients to limit salt intake to no more than the CDRR intake level (100310).
A reduction in sodium intake can lower systolic blood pressure by a small amount in most individuals, and diastolic blood pressure in patients with hypertension (100310,100311,106261). However, post hoc analysis of a small crossover clinical study in White patients suggests that 24-hour blood pressure variability is not affected by high-salt intake compared with low-salt intake (112910). Additionally, the available research is insufficient to confirm that a further reduction in sodium intake below the CDRR intake level will lower the risk for chronic disease (100310,100311). A meta-analysis of clinical research shows that reducing sodium intake increases levels of total cholesterol and triglycerides, but not low-density lipoprotein (LDL) cholesterol, by a small amount (106261).
It is unclear whether there are safety concerns when sodium is consumed in amounts lower than the adequate intake (AI) levels. Some observational research has found that the lowest levels of sodium intake might be associated with increased risk of death and cardiovascular events (98181,98183). However, this finding has been criticized because some of the studies used inaccurate measures of sodium intake, such as the Kawasaki formula (98177,98178,101259). Some observational research has found that sodium intake based on a single 24-hour urinary measurement is inversely correlated with all-cause mortality (106260). The National Academies Consensus Study Report states that there is insufficient evidence from observational studies to conclude that there are harmful effects from low sodium intake (100310).
Endocrine ...Orally, a meta-analysis of observational research has found that higher sodium intake is associated with an average increase in body mass index (BMI) of 1. 24 kg/m2 and an approximate 5 cm increase in waist circumference (98182). It has been hypothesized that the increase in BMI is related to an increased thirst, resulting in an increased intake of sugary beverages and/or consumption of foods that are high in salt and also high in fat and energy (98182). One large observational study has found that the highest sodium intake is not associated with overweight or obesity when compared to the lowest intake in adolescents aged 12-19 years when intake of energy and sugar-sweetened beverages are considered (106265). However, in children aged 6-11 years, usual sodium intake is positively associated with increased weight and central obesity independently of the intake of energy and/or sugar-sweetened beverages (106265).
Gastrointestinal ...In one case report, severe gastritis and a deep antral ulcer occurred in a patient who consumed 16 grams of sodium chloride in one sitting (25759). Chronic use of high to moderately high amounts of sodium chloride has been associated with an increased risk of gastric cancer (29405).
Musculoskeletal
...Observational research has found that low sodium levels can increase the risk for osteoporosis.
One study has found that low plasma sodium levels are associated with an increased risk for osteoporosis. Low levels, which are typically caused by certain disease states or chronic medications, are associated with a more than 2-fold increased odds for osteoporosis and bone fractures (101260).
Conversely, in healthy males on forced bed rest, a high intake of sodium chloride (7.7 mEq/kg daily) seems to exacerbate disuse-induced bone and muscle loss (25760,25761).
Oncologic ...Population research has found that high or moderately high intake of sodium chloride is associated with an increased risk of gastric cancer when compared with low sodium chloride intake (29405). Other population research in patients with gastric cancer has found that a high intake of sodium is associated with an approximate 65% increased risk of gastric cancer mortality when compared with a low intake. When zinc intake is taken into consideration, the increased risk of mortality only occurred in those with low zinc intake, but the risk was increased to approximately 2-fold in this sub-population (109400).
Pulmonary/Respiratory ...In patients with hypertension, population research has found that sodium excretion is modestly and positively associated with having moderate or severe obstructive sleep apnea. This association was not found in normotensive patients (106262).
Renal ...Increased sodium intake has been associated with impaired kidney function in healthy adults. This effect seems to be independent of blood pressure. Observational research has found that a high salt intake over approximately 5 years is associated with a 29% increased risk of developing impaired kidney function when compared with a lower salt intake. In this study, high salt intake was about 2-fold higher than low salt intake (101261).
General ...Orally, turkey tail mushroom and its PSK component are generally well tolerated. There have been reports of gastrointestinal side effects, hematological abnormalities, liver dysfunction, and palpitations, but these are in patients who received PSK in addition to standard chemotherapy. It is not known if these are due to PSK, the chemotherapy, or both.
Cardiovascular ...Palpitations have occurred when PSK is taken with standard chemotherapy for cancer (1657). It is not clear if this is due to PSK, the chemotherapy, or both.
Dermatologic
...Pigmentation of the nails and erythema have occurred when PSK is taken with standard chemotherapy (1657,1660,70175,94076).
It is not clear if this is due to PSK, the chemotherapy, or both.
Intravaginally, a specific gel (Papilocare, Procare Health) containing turkey tail mushroom with neem, carboxymethyl-beta-glucan, hyaluronic acid, gotu kola, aloe, and alpha-glucan oligosaccharide has been reported to cause vulvovaginal stinging, burning, itching, and candidiasis (108305,111904). The specific role of turkey tail mushroom is unclear.
Gastrointestinal ...Nausea, vomiting, appetite loss, stomach discomfort, diarrhea, constipation, and gastric ulcer have occurred when PSK is taken with standard chemotherapy for cancer (1651,1657,70175,70201,94076). However, one study reported a decreased incidence of gastrointestinal side effects when PSK was taken with chemotherapy (70188,70197).
Hematologic ...Leukopenia, thrombocytopenia, and albuminuria have occurred when PSK is taken with standard chemotherapy (1651,1657,70175,70201,94076). It is not clear if this is due to PSK, the chemotherapy, or both.
Hepatic ...Elevated liver enzymes, liver function impairment, and hepatotoxicity have occurred when PSK is taken with standard chemotherapy (1651,1657,70175,70201,94076). It is not clear if this is due to PSK, the chemotherapy, or both.
Musculoskeletal ...Malaise and fatigue have occurred when PSK is taken with standard chemotherapy (1657,1660,70175,94076). It is not clear if this is due to PSK, the chemotherapy, or both.
Pulmonary/Respiratory ...Coughing has occurred when PSK is taken with standard chemotherapy (1657,1660,70175,94076). It is not clear if this is due to PSK, the chemotherapy, or both.
General
...Orally or intramuscularly, vitamin D is well tolerated.
Serious Adverse Effects (Rare):
Orally or intramuscularly: Excessive doses can lead to vitamin D toxicity with symptoms of hypercalcemia, and also sometimes azotemia and anemia.
Cardiovascular ...Vitamin D intoxication can occur when vitamin D supplements are taken orally in excessive doses. Rarely, people develop hypertension (10142). An analysis of clinical research suggests that, when taken orally, vitamin D might modestly increase levels of low-density lipoprotein (LDL)-cholesterol. However, it is not clear if this increase is clinically significant (84642).
Gastrointestinal ...Orally, vitamin D may cause dry mouth. In clinical research, intake of vitamin D 50,000 IU weekly for 4 weeks followed by 50,000 IU monthly for 5 months thereafter was associated with a 3.7-fold increase in reports of dry mouth compared with placebo (91348).Vitamin D intoxication can occur when vitamin D supplements are taken orally in excessive doses. Symptoms of vitamin D toxicity include pancreatitis (10142,84433). Vomiting occurred in one patient given a single dose of 200,000 IU (104624).
Genitourinary ...Vitamin D intoxication can occur when vitamin D supplements are taken orally in excessive doses. Advanced symptoms may include decreased libido (10142). Vaginal discharge and itching have been reported in a clinical trial following oral use (91348).
Hematologic
...Lab values of urinary and blood calcium, phosphate, albumin, blood urea nitrogen, serum cholesterol, aspartate aminotransferase, and alanine aminotransferase concentrations might increase with vitamin D use, especially with high doses (10142,91349,93943).
A case of elevated international normalized ration (INR) has been reported for an 84 year-old patient who took vitamin D 50,000 IU daily for 2 months. The patient's serum levels of vitamin D increased from <7 ng/mL to 100 ng/mL over 6 months. To resolve symptoms, vitamin D supplementation was discontinued (84433).
Musculoskeletal ...Vitamin D intoxication can occur when vitamin D supplements are taken in excessive doses (10142,17506). Symptoms of vitamin D toxicity include osteoporosis in adults and decreased growth in children (10142).
Ocular/Otic ...Vitamin D intoxication can occur when vitamin D supplements are taken orally in excessive doses (10142,17506). Symptoms of vitamin D toxicity include calcific conjunctivitis and photophobia (10142).
Psychiatric ...Vitamin D intoxication can occur when vitamin D supplements are taken orally in excessive doses (10142,17506). In rare cases, symptoms of vitamin D toxicity include psychosis (10142,93002).
Pulmonary/Respiratory ...Vitamin D intoxication can occur when vitamin D supplements are taken orally in excessive doses. Advanced symptoms of vitamin D toxicity may include runny nose (10142,17506,93002).
Renal ...Vitamin D intoxication can occur when vitamin D supplements are taken orally in excessive doses. Symptoms of vitamin D toxicity include azotemia. Vitamin D may also cause hypercalcemia, with advanced symptoms including kidney stones or kidney insufficiency due to precipitation of calcium phosphate in the tubules. Symptoms of renal impairment include frequency, nighttime awakening to urinate, thirst, inability to concentrate urine, and proteinuria. Renal impairment is usually reversible with discontinuation of vitamin D supplements (10142,93002,93943,110831,110833).
