Below is general information about the safety of the known ingredients contained in the product Sleep 60 10 in 1 Melatonin Sleep Complex. 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 in amounts commonly found in foods.
POSSIBLY SAFE ...when used orally in medicinal amounts, short-term. GABA has been used with apparent safety in doses of 75 mg to 1.5 grams daily for up to one month in small clinical studies (19361,19363,19369,110134,110135). There is insufficient reliable information available about the safety of GABA when used orally for longer than one month or when used sublingually or intravenously.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when consumed in amounts commonly found in foods. Hops extract and hops oil have Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when hops extract and hops-derived bitter acids are used orally and appropriately for medicinal purposes, short-term. Hops extract has been used with apparent safety in doses of up to 300 mg daily for 2-3 months. Hops-derived bitter acids have been used with apparent safety at a dose of 35 mg daily for 3 months (12,55338,55370,102899,105953,107813).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in the amounts commonly found in foods. L-tryptophan is an essential amino acid that must be obtained from the diet. A typical diet in the United States supplies 0.5-2 grams of L-tryptophan daily (1146).
POSSIBLY SAFE ...when used orally in medicinal amounts, short-term. L-tryptophan 5 grams daily for 21 days has been used with apparent safety (91460,97243). In 1989, L-tryptophan was linked to over 1500 reports of eosinophilia-myalgia syndrome (EMS) and several deaths (7067,8053,10085,11474,11478), leading to its removal from the U.S. market in 1990 (7067). The exact cause of EMS in patients taking L-tryptophan is unknown, but some evidence suggests that nearly all cases were due to contaminated L-tryptophan products from a single manufacturer (8050,8051,11477,11478). Under the Dietary Supplement Health and Education Act (DSHEA) of 1994, L-tryptophan is currently available and marketed as a dietary supplement. There is insufficient reliable information available about the safety of L-tryptophan when used orally, long-term.
PREGNANCY: LIKELY SAFE
when used orally in amounts commonly found in foods.
PREGNANCY: POSSIBLY UNSAFE
when used orally in medicinal amounts because it may cause respiratory depression in utero (1142).
Avoid using in amounts greater than those found in foods.
LACTATION: LIKELY SAFE
when used orally in amounts commonly found in foods.
There is insufficient reliable information available about the safety of larger medicinal amounts; 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).
LIKELY SAFE ...when used orally and appropriately (11726,11727,11728,11729,11730,93729). ...when used parenterally and appropriately (2275,2276,2278,11726,11727,11728,11729). There is insufficient reliable information available about the safety of MCTs when used topically.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately, short-term or as a single dose. Melatonin seems to be safe when used up to 8 mg daily for up to 6 months. Melatonin 10 mg daily has been used safely for up to 2 months (1049,1068,1077,1085,1738,1754,5854,5855,5857,12226), (14283,15005,62850,89502,89503,88285,88289,88293,88294,88295)(88296,88299,89508,89510,89511,96313,96314,96316,96317,96319)(96321,97438,99345,103484,106301,106303,107811,110286,110299). ...when used topically and appropriately (1066,1768,1769,4713,4714,96314).
POSSIBLY SAFE ...when doses of up to 8 mg daily are used orally and appropriately for longer than 6 months, doses of 10 mg daily are used for longer than 2 months, or doses of 50 mg daily are used for up to 5 days (7040,7043,62435,106296,107811). There is some evidence melatonin can be used safely in doses of up to 10 mg daily for up to 2 years in some patients (7040,7043,62435). ...when used intravenously under the supervision of a healthcare professional. A one-time dose of intravenous melatonin combined with a single bolus of intracoronary melatonin has been used with apparent safety in one clinical trial (96324).
CHILDREN: POSSIBLY SAFE
when used orally in low doses, short-term (9980,15034,62792,88282,88283,88286,88288,95748,96318,97434)(97439,97446,106293,110292,113216,113223,113224).
Although melatonin has been safely used in clinical research in doses up to 12 mg daily (88283), it is often advised that daily doses of melatonin be limited to 3 mg daily for children and infants 6 months or older and 5 mg daily for adolescents (95746). There is some concern that taking melatonin might adversely affect gonadal development in children (1739,1740,1742,1743). While some evidence suggests that long-term use of melatonin in children may delay puberty, the available research includes only three small, observational studies with incomplete follow-up and poor measures of pubertal timing (95747). Although rare, pediatric overdose with melatonin has resulted in hospitalization, mechanical ventilation, and death (108145). Due to potential risks, melatonin should be used only in children with a medical reason for use; it should not be used to promote sleep in otherwise healthy children. There is insufficient reliable information available about the safety of melatonin when used long-term.
PREGNANCY: POSSIBLY UNSAFE
when used orally or parenterally in high doses or with frequent use.
High doses of melatonin 75-300 mg daily seem to inhibit ovulation, causing a contraceptive effect (769,1740,6002,8271,95728). Advise pregnant patients and patients wishing to become pregnant to avoid using melatonin frequently or in high doses.
There is insufficient reliable information available about the safety of melatonin in lower doses during pregnancy. Some research shows that taking melatonin 2 mg daily does not affect anterior pituitary hormone levels in females who are not pregnant; this suggests that low doses may not have a contraceptive effect (62898). Other research shows that taking melatonin 3 mg daily during the follicle stimulating stage of in vitro fertilization does not negatively impact pregnancy rates (62818,62819,88297,89512,88297). However, it is not known if melatonin is safe for use throughout pregnancy (95729). Until more is known about the safety of melatonin, avoid using during pregnancy.
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally as a flavoring in foods. The US Food and Drug Administration (FDA) lists passion flower as a permitted food flavoring additive, to be used in the minimum quantity necessary (91203).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts, short-term. Passion flower extract has been used with apparent safety at doses up to 800 mg daily for up to 8 weeks (88198,102866). A specific passion flower extract (Pasipay, Iran Darouk Pharmaceutical Company) has been safely used at a dose of 45 drops daily for up to one month (8007,95036). Also, a tea prepared by steeping 2 grams of the dried aerial parts of passion flower in 250 mL of boiling water for 10 minutes has been used nightly for 7 nights (17374). There is insufficient reliable information available about the safety of passion flower when used topically.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
A specific passion flower product (Pasipay, Iran Darouk Pharmaceutical Company) has been used safely in children aged 6-13 years at a dose of 0.04 mg/ kg daily for 8 weeks (88197).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Some case reports suggest that passion flower use during the first and second trimesters of pregnancy may be associated with an increased risk for premature rupture of membranes and meconium aspiration syndrome; however, causality has not been confirmed (97279). The alkaloids harman and harmaline, which are sometimes found in passion flower, have been reported to have uterine stimulant activity (4,11020,95037). It is not known whether these constituents are present in sufficient quantities to have an effect.
LACTATION:

LIKELY SAFE ...when used orally in amounts commonly found in foods. Roman chamomile has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when used topically as a 2% gel for up to 4 weeks (107369). ...when the essential oil is inhaled or used topically as aromatherapy (7107). There is insufficient reliable information available about the safety of Roman chamomile when used orally in amounts greater than those found in foods.
PREGNANCY: LIKELY UNSAFE
when used orally in medicinal amounts.
Roman chamomile is believed to be an abortifacient (4). Some population research has found a possible link between the use of Roman chamomile and an increased incidence of reduced birth weight, threatened miscarriage, and preterm labor (97292). There is insufficient reliable information available about the safety of the topical use of Roman chamomile during pregnancy; avoid using.
LACTATION:
Insufficient reliable information available; avoid using (4).
LIKELY SAFE ...when used orally and appropriately, short-term. Valerian 300-600 mg daily has been safely used in clinical studies in over 12,000 patients for up to 6 weeks (2074,3484,3485,4032,15018,17577,17578,19409,96242,103221)(104010,105718). There is insufficient reliable information available about the safety of valerian when used orally for longer than 6 weeks.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
Valerian 160-320 mg has been used with apparent safety in children under 12 years of age for 4-8 weeks (14416).

Below is general information about the interactions of the known ingredients contained in the product Sleep 60 10 in 1 Melatonin Sleep Complex. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
 Details
|
Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Details
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure (19279). Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
|
Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
Details
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin) (3710). This may also occur with other benzodiazepines.
|
Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Details
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics (3710).
|
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
Details
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes (111404).
|
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
Details
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes (111404).
|
Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Details
|
Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Details
|
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).
|
Theoretically, taking GABA with antihypertensive drugs might increase the risk of hypotension.
Details
Some clinical research shows that GABA can decrease blood pressure in patients with hypertension (19367).
|
Theoretically, GABA might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Details
Endogenous GABA has well-established relaxant effects (51152) and GABA(A) receptors have an established physiological role in sleep (51143). However, the effects of GABA supplements are unclear, as it is unknown whether exogenous GABA crosses the blood-brain barrier (51120,51153,90570). Although there have been limited reports of drowsiness or tiredness with GABA supplements (5115,19364), these effects have not been widely reported in clinical studies. Additionally, intravenous GABA 0.1-1 mg/kg has been shown to induce anxiety in a dose-dependent manner (5116).
|
Theoretically, concomitant use of hops with sedative drugs might cause additive sedation.
Details
|
Hops extract does not seem to affect the metabolism of CYP1A2 substrates.
Details
In vitro research suggests that flavonoid constituents of hops inhibit CYP1A2 enzyme activity (10686). However, a pharmacokinetic study in healthy postmenopausal patients shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, does not affect levels of caffeine, a CYP1A2 probe substrate (105954).
|
Theoretically, hops extract might alter metabolism of CYP3A4 substrates; however, this effect may not be clinically significant.
Details
Animal research suggests that specific constituents of hops, called lupulones, can induce hepatic CYP3A4 enzyme activity (55325). However, a pharmacokinetic study in healthy postmenopausal patients with normal metabolism shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, decreases the concentration of alprazolam, a CYP3A4 probe substrate, by 7.6%. This reduction is unlikely to be clinically relevant (105954).
|
Theoretically, concomitant use of large amounts of hops might interfere with hormone replacement therapy due to competition for estrogen receptors.
Details
|
Theoretically, concomitant use of L-tryptophan with CNS depressants might cause additive sedative effects.
Details
Clinical research shows that L-tryptophan can cause fatigue and drowsiness (1143).
|
Theoretically, combining L-tryptophan with serotonergic drugs might cause additive serotonergic effects.
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, melatonin may have anticoagulant effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
There are isolated case reports of minor bleeding and decreased prothrombin activity in people taking melatonin with warfarin (Coumadin) (63067). The mechanism, if any, of this interaction is unknown (9181). Taking melatonin orally seems to decrease coagulation activity within one hour of dosing in healthy men (62481).
|
Theoretically, melatonin may reduce the effects of anticonvulsants.
Some clinical research suggests that melatonin may increase the frequency of seizures in certain patients, particularly children with neurological impairment (8248,9744).
|
Theoretically, taking melatonin with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Some clinical research shows that melatonin reduces levels of fasting blood glucose and improves glycemic control (19034,19035,103490). However, other research suggests that melatonin might impair glucose utilization and increase insulin resistance (9713), while other research has found no effect on glucose levels (19036,104368). Until more is known, use melatonin cautiously in combination with antidiabetes drugs.
|
Theoretically, taking melatonin with antihypertensive drugs might increase the risk of hypotension or hypertension.
Details
Some clinical research suggests that taking melatonin decreases blood pressure in healthy adults (1724,62165,62187,63042). Also, melatonin seems to lower systolic and diastolic blood pressure in individuals with high blood pressure at nighttime or untreated essential hypertension (62359,62416,62441,62826). However, melatonin seems to worsen blood pressure in patients who are taking antihypertensive medications. Immediate-release melatonin 5 mg at night in combination with nifedipine GITS (Procardia XL) increases systolic blood pressure an average of 6.5 mmHg, diastolic blood pressure by an average of 4.9 mmHg, and heart rate by 3.9 bpm (6436). Also, results from animal research suggest that melatonin reduces the effectiveness of certain antihypertensive drugs, including methoxamine and clonidine (62432).
|
Theoretically, taking caffeine with melatonin might increase levels of melatonin.
Details
Some evidence suggests that caffeine consumption can decrease endogenous melatonin levels (8265,22303,37585), while other evidence suggests that caffeine increases endogenous melatonin levels (62328). When administered in combination with melatonin supplements, caffeine seems to increase melatonin effects and levels (62352,96315). The reason for this discrepancy is not completely clear. Part of the discrepancy may result from the fact that caffeine can inhibit melatonin synthesis as well as inhibit melatonin metabolism. By functioning as an adenosine receptor antagonist, caffeine may indirectly inhibit the synthesis of melatonin. Conversely, because melatonin and caffeine are both metabolized by cytochrome P450 1A2 (CYP1A2) enzyme, concomitant use of melatonin and caffeine may reduce the metabolism of melatonin, resulting in higher serum levels (22306,96315).
|
Theoretically, taking melatonin might increase the sedative effects of CNS depressants.
Details
Melatonin has sedative effects. Theoretically, concomitant use of melatonin with alcohol, benzodiazepines, or other sedative drugs might cause additive sedation (96315).
|
Theoretically, taking contraceptive drugs with melatonin might increase the effects and adverse effects of melatonin.
Details
Contraceptive drugs can increase the levels of endogenous melatonin (8265). Theoretically, these drugs may increase the effects and adverse effects of oral melatonin.
|
Theoretically, melatonin might increase levels of drugs metabolized by CYP1A2. Also, other CYP1A2 substrates might decrease the metabolism of melatonin, increasing melatonin levels.
Details
Melatonin is metabolized in the liver primarily by the CYP2C19 and CYP1A2 enzymes (62118,62405,96315). Theoretically, combined administration of melatonin with drugs metabolized by the CYP1A2 enzyme might reduce the metabolism of these drugs, resulting in increased serum levels. Conversely, some drugs metabolized by CYP1A2 may inhibit the metabolism of melatonin, resulting in increased serum levels of melatonin. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.
|
Theoretically, melatonin might increase levels of drugs metabolized by CYP2C19. Also, other CYP2C19 substrates might decrease the metabolism of melatonin, increasing melatonin levels.
Details
Melatonin is metabolized in the liver primarily by the CYP2C19 and CYP1A2 enzymes (62118,62405). Theoretically, combined administration of melatonin with certain drugs metabolized by the CYP2C19 enzyme may reduce the metabolism of these drugs, resulting in increased serum levels. Conversely, some drugs metabolized by CYP2C19 may inhibit the metabolism of melatonin, resulting in increased serum levels of melatonin. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.
|
Theoretically, melatonin might increase levels of drugs metabolized by CYP2D6.
Details
Laboratory research suggests that certain lots of melatonin inhibit CYP2D6 (96315). Theoretically, combined administration of melatonin with certain drugs metabolized by the CYP2D6 enzyme may reduce the metabolism of these drugs, resulting in increased serum levels. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.
|
Theoretically, melatonin might increase levels of drugs metabolized by CYP3A4.
Details
Laboratory research shows that certain lots of melatonin inhibit CYP3A4 (96315). Theoretically, combined administration of melatonin with certain drugs metabolized by CYP3A4 may reduce the metabolism of these drugs, resulting in increased serum levels. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.
|
Theoretically, taking flumazenil with melatonin might reduce the effects of melatonin.
Details
Animal research shows that flumazenil may inhibit the effect of melatonin (9703).
|
Theoretically, taking fluvoxamine with melatonin might increase levels of melatonin.
Details
Fluvoxamine can significantly increase melatonin levels. In some cases, fluvoxamine might increase bioavailability of exogenously administered melatonin by up to 20 times (5038,6499,8251). Some researchers think this might be a beneficial interaction and be potentially useful for cases of refractory insomnia (6499). However, this interaction might also cause unwanted excessive drowsiness and possibly other adverse effects. Fluvoxamine is known to increase endogenous melatonin secretion (6498,22313). It seems to increase serum levels of exogenously administered melatonin possibly by decreasing melatonin metabolism by inhibiting cytochrome P450 (CYP450) 1A2 and 2C19 or by inhibiting melatonin elimination. This effect has been found in healthy people taking fluvoxamine 50-75 mg and melatonin 5 mg (5038,6498,6499,8251).
|
Theoretically, melatonin might interfere with immunosuppressive therapy.
Details
Melatonin can stimulate immune function. Theoretically, melatonin might interfere with immunosuppressive therapy (7040).
|
Theoretically, taking melatonin with methamphetamine may increase the adverse effects of methamphetamine.
Details
Animal research suggests that melatonin exacerbates the adverse effects of methamphetamine, resulting in greater depression of tryptophan hydroxylase (TPH) and tyrosine hydroxylase (TH) activity, as well as a significant reduction in dopamine levels (22307). This has not been shown in humans.
|
Theoretically, taking melatonin with extended release nifedipine reduces the effects of nifedipine.
Details
Melatonin can decrease the effectiveness of extended release nifedipine (GITS). Immediate-release melatonin 5 mg at night in combination with nifedipine GITS 30-60 mg daily increases systolic and blood pressure by an average of 6.5 mmHg and 4.9 mmHg, respectively. Concomitant use with melatonin also increases heart rate by 3.9 bpm (6436). The mechanism of this interaction is not known.
|
Theoretically, taking melatonin with drugs that lower the seizure threshold might increase the risk of seizure activity.
Details
|
Theoretically, melatonin may have antiplatelet effects and may increase the risk of bleeding with warfarin.
Details
Three cases of increased prothrombin time have been reported for patients aged 48-72 years who took melatonin orally in combination with warfarin (9181). However, three cases of decreased prothrombin time have also been reported for patients aged 51-84 years who took melatonin orally in combination with warfarin (9181). Until more is known, use melatonin cautiously in patients taking warfarin.
|
Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Details
|
Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
Details
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer (110704).
|
Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
Details
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition (105095). OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.
|
Valerian can have additive sedative effects when used concomitantly with alcohol.
Details
Valerian has sedative effects (9894). Theoretically, valerian might have an additive sedative effect when combined with alcohol. Excessive sedation has been reported in an alcohol-abusing individual who took valerian and Gingko biloba (19426). However, the potential interaction between valerian and alcohol has been disputed in other research. Limited evidence suggests that a combination of valerian 160 mg and lemon balm 80 mg (Euvegal) does not cause further deterioration in reaction ability and reaction rate when taken with alcohol as compared to the effects of alcohol alone (19427).
|
Valerian can have additive sedative effects when used with alprazolam. Also, valerian in high doses might modestly increase alprazolam levels, though this is not likely to be clinically significant.
Details
Valerian has sedative effects (9894). Theoretically, valerian might cause additive sedation when combined with alprazolam. Also, a small pharmacokinetic study shows that taking valerian extract 1000 mg daily (providing 11 mg valerenic acid) might increase alprazolam levels by about 19%. This might be due to valerian's mild inhibition of cytochrome P450 3A4 (CYP3A4) (13014). Despite being statistically significant, this increase is not likely to be clinically significant.
|
Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Details
|
Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.
Details
Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme (13014,13536,19430,19431). In one PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days did not affect the metabolism of dextromethorphan, a CYP2D6 substrate. In another PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of debrisoquine, an accepted CYP2D6 probe-substrate (13014,13536).
|
Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.
Details
Although some in vitro evidence suggests that valerian extract might inhibit or induce CYP3A4, clinical pharmacokinetic (PK) studies show that valerian does not have a clinically significant effect on the CYP3A4 enzyme (6450,12214,13014,13536,19431). In one PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of midazolam, an accepted CYP3A4 probe-substrate. In another PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days modestly increases levels of alprazolam, a CYP3A4 substrate, suggesting mild inhibition of CYP3A4 (13014,13536). However, this mild inhibition is unlikely to be clinically relevant.
|
Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.
Details
In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7 (81685).

Below is general information about the adverse effects of the known ingredients contained in the product Sleep 60 10 in 1 Melatonin Sleep Complex. 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, ashwagandha seems to be well-tolerated.
Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Diarrhea, gastrointestinal upset, nausea, and vomiting. However, these adverse effects do not commonly occur with typical doses.
Serious Adverse Effects (Rare):
Orally: Some case reports raise concerns about acute hepatitis, acute liver failure, hepatic encephalopathy, the need for liver transplantation, and death due to liver failure with ashwagandha treatment.
Dermatologic ...Orally, dermatitis has been reported in three of 42 patients in a clinical trial (19276).
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, GABA seems to be generally well tolerated.
Sublingually, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Drowsiness, gastric upset, minor throat burning, muscle weakness, and nausea.
Cardiovascular ...Intravenously, GABA can cause dose-related increases in blood pressure and pulse (5116).
Gastrointestinal ...Orally, minor throat burning has been associated with GABA in one study (5115). In another study in which GABA was administered with phosphatidylserine, one patient experienced severe gastric distress, two patients reported moderate nausea, and one reported constipation (19364). Children with cerebral palsy taking GABA experienced nausea and decreased appetite (19362).
Genitourinary ...In one study, one patient treated with oral GABA and phosphatidylserine reported transient amenorrhea (19364).
Musculoskeletal ...Orally, minor adverse effects associated with GABA included muscle weakness (5115).
Neurologic/CNS ...Orally, GABA may cause drowsiness, headache, or tiredness (5115,19364,112830). Four children with cerebral palsy taking GABA had convulsions, and an unspecified number experienced motor restlessness. However, causality of these adverse effects was not clear, and the dose of GABA was not specified (19362). Intravenously, GABA 50 mg has been associated with a "lack of alertness" in healthy female volunteers (51159).
Psychiatric ...Intravenously, GABA 0. 1-1.0 mg/kg has been shown to induce anxiety, dysphoria, and mood disturbances in a dose-dependent manner (5116).
Other ...In one study, patients taking GABA experienced a slight warming of the body (19370).
General
...Orally, hops extract and oil are generally well tolerated when used in food amounts.
Hops extract also seems to be well tolerated when used in supplemental amounts.
Most Common Adverse Effects:
Orally: Drowsiness, sedation.
Dermatologic ...Topically, allergic reactions have been reported after contact with the fresh hops plant and plant dust. Contact dermatitis is attributed to the pollen (4,12,105930).
Genitourinary ...Orally, supplements containing hops and soy have been associated with 4 cases of postmenopausal bleeding (55404). It is unclear if this effect is due to hops, soy, or the combination. Also, menstrual disturbances have been reported in female workers harvesting hops (10684,55405).
Neurologic/CNS ...Orally, hops might cause drowsiness and sedation. Historically, hops are thought to have sedative effects, since workers harvesting hops were observed to tire easily after oral contact with hop resin. The European Medicines Agency states that hops may have sedative effects; however, there is a lack of clinical research confirming that hops extract causes drowsiness and sedation (105930).
Pulmonary/Respiratory ...Occupational exposure to dust from hops, usually in combination with dust from other products, is associated with chronic respiratory symptoms such as dry cough, dyspnea, chronic bronchitis, and other occupational respiratory diseases (55333,55414).
General
...Orally, L-tryptophan is generally well tolerated.
Most Common Adverse Effects:
Orally: Belching, diarrhea, drowsiness, dry mouth, flatulence, headache, heartburn, lightheadedness, nausea, stomach pain, visual blurring, and vomiting.
Serious Adverse Effects (Rare):
Orally: L-tryptophan has been associated with the neurological disorder eosinophilia-myalgia syndrome (EMS). However, almost all cases were traced to L-tryptophan produced by a single manufacturer in Japan and are likely related to contamination.
Cardiovascular ...Orally, L-tryptophan has been associated with eosinophilia-myalgia syndrome (EMS), which can include cardiovascular symptoms such as myocarditis, arrhythmias, and palpitations (8053,11477).
Dermatologic ...Orally, L-tryptophan has been associated with eosinophilia-myalgia syndrome (EMS), which can include dermatological symptoms such as sclerodermiform skin changes, alopecia, and rash (8053,11477).
Gastrointestinal ...Orally, L-tryptophan can cause gastrointestinal side effects such as heartburn, stomach pain, belching and flatulence, nausea, vomiting, diarrhea, dry mouth, and anorexia (10853,99884).
Hematologic ...Orally, L-tryptophan has been associated with eosinophilia-myalgia syndrome (EMS), which can include hematologic symptoms such as eosinophilia (8053,11477).
Hepatic ...Orally, L-tryptophan has been associated with eosinophilia-myalgia syndrome (EMS), which can include hepatic symptoms such as hepatomegaly (8053,11477).
Musculoskeletal ...Orally, L-tryptophan has been associated with eosinophilia-myalgia syndrome (EMS), which can include musculoskeletal symptoms such as myalgia and inflammation of the joints and connective tissue (8053,11477).
Neurologic/CNS
...Orally, L-tryptophan can cause headache, lightheadedness, and ataxia (10853,99884).
In 1989, more than 1500 cases of the neurological disorder EMS were associated with oral L-tryptophan use in the US. About 95% of all EMS cases were traced to contaminated L-tryptophan produced by a single manufacturer in Japan (8054,10288,10289,11475,11476). In 1990, L-tryptophan was recalled in the U.S. and an FDA alert was put into force limiting the importation of all over-the-counter L-tryptophan products (7067,11477,11478). After the limitation of L-tryptophan products, the incidence of EMS dropped abruptly (11474). Symptoms of EMS associated with L-tryptophan use include intense eosinophilia; fatigue; myalgia; neuropathy; sclerodermiform skin changes; alopecia; rash; and inflammatory disorders affecting the joints, connective tissue, lungs, heart, and liver (8053,11477). Symptoms tend to improve over time, however some individuals may still experience symptoms up to 2 years after the onset of EMS and complete resolution of symptoms may not occur (8053,10287).
There is some evidence of an association between L-tryptophan-related EMS and the occurrence of chronic B-cell lymphocytic leukemia (8055).
Ocular/Otic ...Orally, L-tryptophan can cause side effects such as visual blurring (10853).
Pulmonary/Respiratory ...Orally, L-tryptophan has been associated with eosinophilia-myalgia syndrome (EMS), which can include respiratory symptoms such as dyspnea and cough (8053,11477).
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, MCTs can cause significant gastrointestinal upset, especially with higher doses.
Most Common Adverse Effects:
Abdominal discomfort, diarrhea, essential fatty acid deficiency, intestinal gas noises, irritability, nausea, reflux, vomiting. Gastrointestinal disturbances are thought to be associated with higher doses of MCT. Since MCTs are fats, excessive consumption can result in weight gain.
Cardiovascular ...There is some concern that MCTs may further increase the risk for hypertriglyceridemia in some preterm infants due to immature lipoprotein lipase activity in these infants. A case of extremely elevated triglyceride levels of 4,736 mg/dL and associated lipemia retinalis has been reported at 43 weeks post-menstrual age (PMA) for a preterm infant born at 30 weeks' gestational age. It was discovered that the baby had been receiving MCT supplements in addition to breast milk starting at 42 weeks' PMA. MCT supplements were discontinued. One month later triglycerides were reduced to 287 mg/dL, and the retinal vasculature had a normal hue. However, at 2-month follow-up, triglyceride levels were elevated to levels higher than normal for age despite MCT discontinuation. Investigators speculated that a genetic disorder of lipid metabolism may also have contributed to the elevated triglyceride levels in addition to use of MCTs (96330).
Gastrointestinal ...Orally, MCTs can cause significant gastrointestinal upset. Diarrhea is the most commonly reported side effect (11723,93737,93738,101967). Other reported side effects include vomiting, irritability, nausea, reflux, abdominal discomfort, intestinal gas noises, and essential fatty acid deficiency (11723,93738,101967). Taking MCTs with food can reduce these adverse effects (93737). Gastrointestinal disturbances are thought to be associated with higher doses of MCT, such as 85 grams (93731).
Other ...Excessive consumption of MCTs can result in weight gain. MCT oil contains 6-8.5 calories per gram. One tablespoon provides about 14 grams and about 115 calories (11724).
General
...Orally, melatonin is generally well tolerated.
Most Common Adverse Effects:
Orally: Dizziness, drowsiness, headache, and nausea.
Serious Adverse Effects (Rare):
Orally: There is concern that melatonin may increase the risk for seizure.
Cardiovascular ...Melatonin might increase levels of very low-density lipoprotein (VLDL) cholesterol and triglycerides (62176). Several rare or poorly described cases of abnormal heart rhythms, palpitations, fast heart rate, or chest pain have been reported. However, in these cases, the patients were taking other drugs that could account for the symptoms, and melatonin was not thought to be the cause (1079,9181,62776,62789,63067).
Dermatologic ...Papular skin rash and pruritus has been reported with melatonin use. However, the effect was generally mild and did not require cessation of melatonin treatment (62450,62754,109696), and had similar rates as placebo (96316). Cutaneous flushing has also been reported (62770,62914). Two cases of fixed drug eruption on the genitalia have been reported for patients who used oral melatonin (Nature's Bounty Natural melatonin) for preventing jet lag (88284).
Endocrine ...A case of gynecomastia (increased breast size) has been reported for a 56 year-old patient with amyotrophic lateral sclerosis (ALS) who used oral melatonin, long-term (89430). Also, reduced sperm concentration and sperm motility has been reported for two men who used oral melatonin 3 mg daily for 6 months. Improvement in sperm quality was observed for only one of the two men following melatonin cessation (62231).
Gastrointestinal ...Orally, melatonin may cause nausea (62384,62770), abdominal cramps, or mild abdominal pain (62450,62754,62914,96316), diarrhea (62804,62811,62914), constipation (96316), or decreased appetite (62345,62792). Often these symptoms occur during the first few days of treatment and subside after a few days (62804). In some cases, rates of symptoms are similar between melatonin and placebo (96316). Less often, melatonin has been reported to cause abnormal feces (62450), odd taste in the mouth (1070), or reflux esophagitis (1745) when used orally. A case of exacerbated symptoms of Crohn disease, including increased diarrhea and abdominal cramps, has been reported for a patient who took oral melatonin 3 mg at bedtime for 4 days. Symptoms resolved within 24 hours of melatonin treatment cessation (62218).
Genitourinary ...Orally, melatonin may increase enuresis in adults and children (58685,62450,62710,62770,62804,62804,62811). In perimenopausal adults, melatonin has caused a resumption of spotting or menstrual flow (11806). Decreased libido has been noted for one patient treated with melatonin 3 mg daily for 8 weeks (15216).
Hematologic ...A case of nose bleed has been reported with oral melatonin (62450). Some melatonin preparations contain contaminants that are associated with eosinophilia-myalgia syndrome (9715,9716).
Hepatic ...A case of autoimmune hepatitis has been reported for a patient who took melatonin orally to treat insomnia (63037).
Musculoskeletal ...Preliminary clinical evidence shows that a single dose of melatonin 3 mg may increase fall risk due to increased postural swaying while standing on one or both feet in healthy adults ages 60-71 years (97442). A single case of ataxia has been reported for an 81-year-old female who used melatonin for 4 days (9181). Weakened muscle power has been reported for two patients treated with melatonin 5 mg in the evening (62456). Some melatonin preparations contain contaminants that are associated with eosinophilia-myalgia syndrome (9715,9716).
Neurologic/CNS
...Orally, melatonin may cause migraine-like headache (1070,1077,15034,62384,62450,62710,62754,62804,62792,62914,88288,88293,88294,96318)(106297) or dizziness (62345,62384,62450,62456,62770,62784,62792,62804,62811,89510)(110297).
Often these symptoms occur during the first few days of treatment and subside after a few days (62804). Melatonin may also cause drowsiness or fatigue when taken orally (1077,8273,15216,62384,62456,62784,62804,62811,88288,89510,96314,96316,96318,97446)(106293,106297). These symptoms appear to be more common if melatonin is taken in the morning or at very high doses (greater than 50 mg) (8269,62874). A case of excessive drowsiness has been reported when melatonin was combined with citalopram, nortriptyline, and oxycodone. Sedation improved with discontinuation of melatonin (96315). Indiscriminate use of melatonin may cause irregular sleep-wake cycles to occur (62998). Less commonly, melatonin may also cause behavior worsening (62811), confusion or disorientation (63014,63067), nighttime awakening (62710,62811), mood swings or agitation (96318), stereotypy (96318), excitement before bedtime (62811), nightmares or more intense dreams (62401,62462,62780,62784,88283), feelings of a "rocking" sensation (62155), or reduced alertness when taken orally.
A case of generalized epilepsy has reportedly occurred after treatment with melatonin for 4 months (9708). Also, some case reports raise concerns about increased risk of seizure with melatonin treatment, but conflicting evidence suggests that melatonin may decrease the risk of seizures (1699,8248,9695,9697,9744,9746,62123,62256,62384,62754)(63070,63071,89431). One patient experienced hyponatremia with confusion and seizures after taking prolonged-release melatonin 2 mg. However, malnutrition and cannabis abuse were also thought to contribute to this reaction (96321).
Although there is concern that melatonin might affect cognitive function in healthy adults, research in humans suggests that oral or topical melatonin do not impact most measures of cognitive function (97442,97448).
Psychiatric ...Orally, melatonin may cause mood changes, including dysphoria (sadness) (1764), dips in mood (62345,62450,62792), nervousness (62784), or transient depression (1077). Delusions and hallucinations have also been reported in clinical research (62347). An isolated incident of aggressiveness was also noted in a child diagnosed with attention deficit-hyperactivity disorder (ADHD) who took melatonin in combination with methylphenidate (9980). Severe irritability has been reported in two children with autism spectrum disorder who had abruptly discontinued melatonin due to the completion of a clinical trial (106293).
General
...Orally, passion flower is well tolerated.
Most Common Adverse Effects:
Orally: Confusion, dizziness, hypersensitivity, and sedation.
Cardiovascular ...There is a case report involving a 34-year-old female who was hospitalized with severe nausea, vomiting, drowsiness, prolonged QT interval, and episodes of nonsustained ventricular tachycardia following use of passion flower extract tablets (Sedacalm, Bioplus Healthcare), 1500 mg on day 1 and 2000 mg on day 2 to relieve stress. All symptoms resolved within one week after passion flower was discontinued (6251).
Genitourinary ...The alkaloids harman and harmaline, which are sometimes found in small amounts in passion flower, have been reported to have uterine stimulant activity (4,11020,95037).
Hematologic ...Orally, passion flower has been reported to cause epistaxis in one clinical trial (95038). Vasculitis has also been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).
Hepatic ...There is debate about whether passion flower contains cyanogenic glycosides. Several related Passiflora species do contain these constituents (3), including Passiflora edulis, which is associated with liver and pancreatic toxicity (7).
Immunologic
...An idiosyncratic hypersensitivity reaction characterized by urticaria and cutaneous vasculitis has been reported in a 77-year-old male with rheumatoid arthritis after taking a specific combination product that included passion flower extract (Naturest) (68308).
It is unclear if these effects were caused by passion flower or other ingredients.
In clinical trials, passion flower has been reported to cause allergy symptoms including sinus irritation; however, the frequency of these events was statistically nonsignificant when compared to treatment with midazolam 15 mg (95038).
Musculoskeletal ...Orally, passion flower has been reported to cause muscle relaxation in a clinical trial (95038).
Neurologic/CNS ...Orally, sedation, dizziness, ataxia, and confusion have been reported in clinical trials. However, these events generally do not necessitate discontinuation (8007,15391,15392,95036,95038). Altered consciousness has been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).
General
...Roman chamomile is generally well tolerated.
Most Common Adverse Effects:
Topically: Allergic skin reactions.
Dermatologic ...Topically, Roman chamomile can cause contact dermatitis (4,567,97292). Allergic skin reactions can occur in up to 20% of individuals exposed to Roman chamomile (19). Multiple case reports have described the development of topical allergic reactions, including eczema and rash, with the use of cleaning products and cosmetics containing chamomile oil or chamomile extract (97292). In one case report, a 55-year-old man experienced disseminated erythroderma with itchy, scaly lesions after non-contact exposure to an area containing many plant varieties. Patch testing confirmed the presence of allergenicity to Roman chamomile (97292).
Gastrointestinal ...Orally, large amounts of Roman chamomile might cause vomiting, although data are conflicting (11,12).
Immunologic ...Allergic skin reactions can occur in up to 20% of individuals exposed to Roman chamomile (19). Cross-sensitivity can occur in individuals with sensitivity to the Asteraceae/Compositae family (19,97292). Multiple case reports have described the development of topical and respiratory allergic reactions with the use of cleaning products and cosmetics containing chamomile oil or chamomile extract (97292).
Pulmonary/Respiratory ...A case report describes the development of cough and rhinitis in a 20-year-old female after exposure to chamomile-scented toilet paper. Skin prick testing confirmed the presence of allergenicity to the toilet paper product (97292).
General
...Orally, valerian is generally well-tolerated.
Most Common Adverse Effects:
Orally: Dizziness, drowsiness, and mental slowness. Other reported side effects include headache, gastrointestinal upset, excitability, and vivid dreams. When used chronically and abruptly stopped, symptoms of withdrawal such as tachycardia, anxiety, irritability, and insomnia might occur. Advise patients to taper doses slowly after extended use.
Serious Adverse Effects (Rare):
Orally: Several case reports raise concerns about hepatotoxicity after the use of valerian and valerian-containing multi-ingredient dietary supplements. Withdrawal from chronic valerian use has been associated with cases of cardiac failure and hallucinations.
Cardiovascular ...When used orally in high doses for an extended period of time, valerian withdrawal has been associated with tachycardia and high output cardiac failure in one patient with a history of coronary artery disease (3487). Chest tightness has been reported for an 18-year-old female who took 40-50 capsules containing valerian 470 mg/capsule (659). A case of severe hypotension, suspected to be due to vasodilation, hypocalcemia, and hypokalemia, has been reported for a patient who injected an unknown quantity of a crude tap water extract of raw valerian root (81734).
Dermatologic ...Orally, valerian might rarely cause a rash. A case of valerian-related rash that resolved after valerian root discontinuation was reported in clinical research (19422).
Gastrointestinal ...Orally, valerian has been associated with increased incidence of gastrointestinal problems including diarrhea, nausea, vomiting, and stomach pain (15046,19406,19407,19422,110712). In one individual, taking 20 times the normal dose caused abdominal cramping (659).
Hepatic
...There have been several case reports of hepatotoxicity associated with the use of multi-ingredient oral preparations containing valerian (8243,96241).
In one case report, a 57-year-old man presented with acute hepatitis after consuming a cold and flu remedy containing valerian 2 grams for 3 days; the remedy also contained white willow, elderberry, and horseradish. Although the use of the cold and flu remedy was discontinued one month prior to symptom presentation, the acute hepatitis was attributed to valerian root and treated with steroids (96241). It is possible, however, that some of these preparations may have been adulterated with hepatotoxic agents (8243).
Hepatotoxicity involving long-term use of single-ingredient valerian preparations has also been reported (3484,17578). Also, a case of a 38-year-old female with liver insufficiency and cirrhosis of a vascular parenchymal nature who developed hepatotoxic symptoms following valerian and ethyl-alcohol abuse has been reported (81697). Symptoms resolved and laboratory values normalized following intense plasmapheresis treatment. Another case of acute hepatitis characterized by elevated aminotransferases, mild fibrosis, and liver inflammation has been reported for a 50-year-old female who consumed valerian root extract 5 mL three times weekly along with 10 tablets of viamine, a product containing dry valerian extract 125 mg/tablet, for 2 months (81696). Because a variety of doses were used in these cases, and many people have used higher doses safely, these hepatotoxic reactions might have been idiosyncratic. Tell patients the long-term effect of valerian on liver function is unknown.
Musculoskeletal ...In a case report, combined intake of valerian and passionflower caused throbbing and muscular fatigue when taken concomitantly with lorazepam (19429).
Neurologic/CNS ...Orally, valerian might cause dizziness, headaches, fatigue, sleepiness, and mental dullness (3484,17578,19411,19422,81723,89407). The severity of adverse effects appears to increase with higher doses (19411). However, taking valerian extracts in doses up to 1800 mg does not appear to significantly affect mood or psychomotor performance (10424,15044). Valerian does not usually have a negative impact on reaction time, alertness, and concentration the morning after intake (2074,8296). Clinical research shows that a single dose of valerian root 1600 mg is not associated with any changes in sleepiness, reaction time, or driving performance within 1-4 hours after intake (96240). More serious side effects may occur when valerian is taken at higher doses. In one individual, 20 times the normal dose caused tremor of the hand and foot and lightheadedness (659). In a case report, combined intake of valerian and passionflower caused shaking of the hands and dizziness when taken concomitantly with lorazepam (19429).
Psychiatric ...Orally, valerian has been associate with reports of restlessness, excitability, uneasiness, agitation, and vivid dreams (3484,17578,19411,19422). Chronic use and rapid cessation can lead to withdrawal syndrome with symptoms of agitation, insomnia, and hallucinations (104003). There appears to be a trend towards increased severity of adverse effects with higher doses (19411). A case of acute hypomania has been reported for a 21-year-old female patient who took a valerian decoction in water each night for one month to treat subclinical anxiety. Symptoms included euphoric mood, rapid speech, and increased sociability and sexual interest. Following cessation of valerian use and treatment with quetiapine 100 mg daily for two weeks, the patient recovered (89405). In another case report, an 85-year-old male with mild cognitive impairment, major depression, anxiety, and chronic kidney disease presented to the emergency department with hallucinations, confusion, and agitation thought to be due to abrupt cessation after taking valerian 600 mg daily for about 6 months. The symptoms resolved in about 5 days (104003).
