HelloPharmacist Scorecard of Sleep First Wizard of Zz by Dr. Gumman’s Integrative
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
Sleep First Wizard of Zz contains 9 active ingredients. The main components are melatonin, three forms of magnesium (Magnesium Glycinate, Magnesium Chelate, and Magnesium Gluconate), GABA (gamma-aminobutyric acid), Sarpagandha root powder (Indian snakeroot), 5-hydroxytryptophan (5-HTP), and Ashwagandha Root Extract.
The product also includes a Proprietary Blend and a Magnesium blend whose individual components are listed separately. One ingredient, Jatamansi Root Extract, is included but we hold no interaction data for it.
The capsule itself is vegan.
Does it work?
Strong evidence
Melatonin is likely effective for non-24-hour sleep-wake disorder and delayed sleep phase syndrome (DSPS), and possibly effective for pre-procedural anxiety. The other ingredients have limited or no established evidence for sleep support in our data.
Magnesium is effective for constipation and indigestion but the evidence ratings don't include sleep as an established use. GABA, Sarpagandha root powder, 5-HTP, and Ashwagandha all have insufficient reliable evidence or no clear effectiveness ratings for insomnia or sleep in our records, though ashwagandha is possibly effective for anxiety and stress.
We cannot assess Jatamansi Root Extract because we hold no data on its effectiveness.
How safe is it?
Well-documented data
Melatonin is generally well tolerated for short-term use, though long-term safety is less certain. Common side effects include dizziness, drowsiness, headache, and nausea.
Serious but rare concerns include mood changes (sadness, nervousness, depression) and a possible link to seizures in certain populations. Magnesium is generally well tolerated and is generally safe for healthy adults at recommended doses; common side effects are diarrhea, stomach upset, nausea, and vomiting.
GABA seems well tolerated short-term but long-term safety is not well studied; common effects include drowsiness, stomach upset, and muscle weakness. Sarpagandha root powder contains potent alkaloids and carries caution for serious side effects — it can cause low blood pressure, slow heart rate, depression, and at high doses, heart rhythm problems and heart attack.
5-HTP is generally well tolerated short-term; common side effects include stomach pain, nausea, diarrhea, drowsiness, and headache. Ashwagandha is generally well tolerated short-term in healthy adults; common side effects are mild and include diarrhea, nausea, and vomiting, but rare cases of severe liver damage have been reported.
Meds to double-check
Major interaction found
Before taking this product, double-check with your pharmacist if you take beta-blockers, antipsychotic medications, levodopa/carbidopa, or digoxin — these have Major-severity interactions. Also check if you take blood thinners, blood-pressure drugs, seizure medications, diabetes medications, muscle relaxants, immune-suppressing drugs, thyroid hormone, benzodiazepines, or sedating medications — all have documented Moderate interactions.
If you're unsure about any of your medications, use the search tool on this page.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This is a multi-ingredient sleep product best suited for people with simple sleep troubles who take no medications for heart rhythm, blood pressure, diabetes, Parkinson's disease, seizures, mood, or immune function. If you take any prescription drugs—especially for the heart, brain, or blood — you need to check each one against the interaction tool below before starting.
Talk to your pharmacist or doctor; some of these ingredients carry real risks when combined with common medications.

Sleep First Wizard of Zz by Dr. Gumman’s Integrative Drug Interactions
HelloPharmacist Interaction Report
Sleep First Wizard of Zz by Dr.
Gumman's Integrative contains several ingredients with documented medication interactions. The most serious concern is Sarpagandha root powder (Indian snakeroot), which has Major-severity interactions with beta-blockers, antipsychotic drugs, levodopa, and digoxin — it can reduce heart rate dangerously, worsen Parkinson's symptoms, increase psychotic drug effects, and cause dangerous slowing of the heartbeat.
Read the full breakdown — every affected drug type, severity by severity
Melatonin interacts moderately with blood thinners (including warfarin), heart-rate and blood-pressure medications (nifedipine and other antihypertensives), seizure medications, diabetes drugs, and immune-suppressing medications. The three magnesium forms in this product (Magnesium Glycinate, Magnesium Chelate, Magnesium Gluconate) share Major-severity interactions with levodopa/carbidopa for Parkinson's disease — magnesium can cut the drug's effectiveness by up to 81%.
They also interact moderately with muscle relaxants, blood-pressure medications, diuretics, diabetes drugs, antibiotics (quinolones), and bone medications (bisphosphonates).
5-HTP and Ashwagandha add moderate interactions with sedating medications, mood-altering drugs (especially serotonin-boosting antidepressants), and with ashwagandha also affecting blood-pressure control, blood-sugar control, thyroid hormone, and immune-suppressing drugs. GABA has minor interactions with blood-pressure medications and sedating drugs.
Altogether, these interactions span 1,704 individual medications.

Melatonin
Anticoagulant/Antiplatelet Drugs
Theoretically, melatonin may have anticoagulant effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There are isolated case reports of minor bleeding and decreased prothrombin activity in people taking melatonin with warfarin (Coumadin). The mechanism, if any, of this interaction is unknown. Taking melatonin orally seems to decrease coagulation activity within one hour of dosing in healthy men.
Anticonvulsants
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.
Antidiabetes Drugs
Theoretically, taking melatonin with antidiabetes drugs might increase the risk of hypoglycemia.
Some clinical research shows that melatonin reduces levels of fasting blood glucose and improves glycemic control. However, other research suggests that melatonin might impair glucose utilization and increase insulin resistance, while other research has found no effect on glucose levels. Until more is known, use melatonin cautiously in combination with antidiabetes drugs.
Antihypertensive Drugs
Theoretically, taking melatonin with antihypertensive drugs might increase the risk of hypotension or hypertension.
Some clinical research suggests that taking melatonin decreases blood pressure in healthy adults. Also, melatonin seems to lower systolic and diastolic blood pressure in individuals with high blood pressure at nighttime or untreated essential hypertension. 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. Also, results from animal research suggest that melatonin reduces the effectiveness of certain antihypertensive drugs, including methoxamine and clonidine.
Caffeine
Theoretically, taking caffeine with melatonin might increase levels of melatonin.
Some evidence suggests that caffeine consumption can decrease endogenous melatonin levels, while other evidence suggests that caffeine increases endogenous melatonin levels. When administered in combination with melatonin supplements, caffeine seems to increase melatonin effects and levels. 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.
Cns Depressants
Theoretically, taking melatonin might increase the sedative effects of CNS depressants.
Melatonin has sedative effects. Theoretically, concomitant use of melatonin with alcohol, benzodiazepines, or other sedative drugs might cause additive sedation.
Contraceptive Drugs
Theoretically, taking contraceptive drugs with melatonin might increase the effects and adverse effects of melatonin.
Contraceptive drugs can increase the levels of endogenous melatonin. Theoretically, these drugs may increase the effects and adverse effects of oral melatonin.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, melatonin might increase levels of drugs metabolized by CYP1A2. Also, other CYP1A2 substrates might decrease the metabolism of melatonin, increasing melatonin levels.
Melatonin is metabolized in the liver primarily by the CYP2C19 and CYP1A2 enzymes. 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.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, melatonin might increase levels of drugs metabolized by CYP2C19. Also, other CYP2C19 substrates might decrease the metabolism of melatonin, increasing melatonin levels.
Melatonin is metabolized in the liver primarily by the CYP2C19 and CYP1A2 enzymes. 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.
Fluvoxamine (Luvox)
Theoretically, taking fluvoxamine with melatonin might increase levels of melatonin.
Fluvoxamine can significantly increase melatonin levels. In some cases, fluvoxamine might increase bioavailability of exogenously administered melatonin by up to 20 times. Some researchers think this might be a beneficial interaction and be potentially useful for cases of refractory insomnia. However, this interaction might also cause unwanted excessive drowsiness and possibly other adverse effects. Fluvoxamine is known to increase endogenous melatonin secretion. 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.
Immunosuppressants
Theoretically, melatonin might interfere with immunosuppressive therapy.
Melatonin can stimulate immune function. Theoretically, melatonin might interfere with immunosuppressive therapy.
Methamphetamine (Desoxyn)
Theoretically, taking melatonin with methamphetamine may increase the adverse effects of methamphetamine.
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. This has not been shown in humans.
Nifedipine Gits (Procardia Xl)
Theoretically, taking melatonin with extended release nifedipine reduces the effects of nifedipine.
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. The mechanism of this interaction is not known.
Seizure Threshold Lowering Drugs
Theoretically, taking melatonin with drugs that lower the seizure threshold might increase the risk of seizure activity.
Some clinical evidence suggests that melatonin may increase the frequency of seizures in certain patients, particularly children with neurological disabilities.
Warfarin (Coumadin)
Theoretically, melatonin may have antiplatelet effects and may increase the risk of bleeding with warfarin.
Three cases of increased prothrombin time have been reported for patients aged 48-72 years who took melatonin orally in combination with warfarin. 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. Until more is known, use melatonin cautiously in patients taking warfarin.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, melatonin might increase levels of drugs metabolized by CYP2D6.
Laboratory research suggests that certain lots of melatonin inhibit CYP2D6. 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.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, melatonin might increase levels of drugs metabolized by CYP3A4.
Laboratory research shows that certain lots of melatonin inhibit CYP3A4. 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.
Flumazenil (Romazicon)
Theoretically, taking flumazenil with melatonin might reduce the effects of melatonin.
Animal research shows that flumazenil may inhibit the effect of melatonin.
Ashwagandha Root Extract
Antidiabetes Drugs
Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.
Antihypertensive Drugs
Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
Benzodiazepines
Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.
Cns Depressants
Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.
Hepatotoxic Drugs
Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.
Immunosuppressants
Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.
Thyroid Hormone
Ashwagandha might increase the effects and adverse effects of thyroid hormone.
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. 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.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.
Serotonergic Drugs
Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Sarpagandha root powder
Antipsychotic Drugs
Theoretically, concomitant use might increase the risk of adverse effects.
Concomitant use of neuroleptics with Indian snakeroot may potentiate the effects of these drugs, as well as the alkaloid constituents of Indian snakeroot.
Beta-Blockers
Theoretically, taking Indian snakeroot with beta-blockers might increase the risk of bradycardia and/or hypotension.
Indian snakeroot contains small amounts of reserpine. Reserpine causes catecholamine-depletion. Concomitant use of Indian snakeroot and beta-blockers might increase the risk or bradycardia and/or hypotension.
Digoxin (Lanoxin)
Theoretically, taking Indian snakeroot with digoxin might increase the risk of bradycardia.
Bradycardia has been reported in clinical trials using Indian snakeroot. Concomitant use of digoxin with Indian snakeroot might potentiate this effect.
Levodopa
Theoretically, taking Indian snakeroot with levodopa may reduce the effectiveness of levodopa.
Extrapyramidal motor symptoms and Parkinson-like symptoms have been reported in clinical trials using Indian snakeroot. Concomitant use of Indian snakeroot with levodopa may reduce the effectiveness of levodopa and increase extrapyramidal motor symptoms.
Anticoagulant/Antiplatelet Drugs
Theoretically, taking Indian snakeroot might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Indian snakeroot contains small amounts of the drug yohimbine. In vitro research shows that yohimbine inhibits platelet aggregation.
Antidiabetes Drugs
Theoretically, concomitant use of Indian snakeroot with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that Indian snakeroot lowers blood glucose levels. This effect has not been reported in humans.
Antihypertensive Drugs
Theoretically, concomitant use of Indian snakeroot and antihypertensive drugs might increase the risk of hypotension.
Indian snakeroot, which contains reserpine, can reduce both systolic and diastolic blood pressure.
Cns Depressants
Theoretically, taking Indian snakeroot might cause additive sedative effects.
Sedation and drowsiness have been reported in clinical trials using Indian snakeroot.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, Indian snakeroot might inhibit CYP2D6 enzymes and reduce the metabolism of CYP2D6 substrates.
Indian snakeroot contains small amounts of the drug yohimbine. In vitro research shows that yohimbine inhibits CYP2D6 enzyme activity.
Ephedrine
Theoretically, taking Indian snakeroot with ephedrine might alter the effects and side effects of ephedrine.
Indian snakeroot contains small amounts of reserpine. Reserpine reduces indirect sympathomimetic drug activity. However, another constituent of Indian snakeroot, yohimbine, has stimulant activity and may increase the risk of adverse effects with ephedrine.
Monoamine Oxidase Inhibitors (Maois)
Theoretically, taking Indian snakeroot with MAOIs might cause additive effects.
Yohimbine, a constituent of Indian snakeroot, has MAO inhibitory effects. At high doses, yohimbine is a non-selective inhibitor of MAO.
Stimulant Drugs
Theoretically, concomitant use might cause additive effects.
Yohimbine, a constituent of Indian snakeroot, has sympathomimetic effects and increases blood pressure in a dose-dependent manner. Theoretically, taking Indian snakeroot with stimulant drugs can have additive stimulant and hypertensive effects.
Tricyclic Antidepressants (Tcas)
Theoretically, concomitant use might alter the effects of Indian snakeroot and increase the risk of adverse effects.
A small clinical study in patients taking TCAs for at least 4 weeks shows that receiving doses of intravenous yohimbine, a constituent of Indian snakeroot, 2.5-20 mg daily for up to 7 days precipitates severe anxiety, agitation, and tremor. Also, concomitant use of TCAs with Indian snakeroot may decrease the effects of other rauwolfia alkaloids.
Gamma Amino Butyric Acid
Antihypertensive Drugs
Theoretically, taking GABA with antihypertensive drugs might increase the risk of hypotension.
Some clinical research shows that GABA can decrease blood pressure in patients with hypertension.
Cns Depressants
Theoretically, GABA might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Endogenous GABA has well-established relaxant effects and GABA(A) receptors have an established physiological role in sleep. However, the effects of GABA supplements are unclear, as it is unknown whether exogenous GABA crosses the blood-brain barrier. Although there have been limited reports of drowsiness or tiredness with GABA supplements, 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.
5-Hydroxytryptophan
Carbidopa (Lodosyn)
Combining 5-HTP and carbidopa can increase the risk of serotonergic side effects.
Carbidopa is sometimes used with 5-HTP to minimize peripheral 5-HTP metabolism and boost the amount that reaches the brain. However, this combination might also increase the risk of some side effects including hypomania, restlessness, rapid speech, anxiety, insomnia, and aggressiveness. Combining carbidopa and 5-HTP might also increase the risk of scleroderma-like skin changes due to elevated serotonin levels.
Cns Depressants
Theoretically, concomitant use of 5-HTP with medications that cause sedation might have additive effects.
In clinical trials, 5-HTP has been associated with drowsiness and somnolence.
Serotonergic Drugs
Combining serotonergic drugs with 5-HTP might cause additive serotonergic effects.
5-HTP can increase serotonin levels and cause serotonergic effects. Theoretically, combining serotonergic drugs with 5-HTP might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders. However, serotonin syndrome with 5-HTP has not yet been reported in humans. Monitor patients for signs of serotonin syndrome and other serotonergic side effects if using 5-HTP with serotonergic drugs.
Magnesium
Levodopa/Carbidopa (Sinemet)
Magnesium can reduce the bioavailability of levodopa/carbidopa.
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.
Aminoglycoside Antibiotics
Concomitant use of aminoglycoside antibiotics and magnesium can increase the risk for neuromuscular weakness.
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.
Antacids
Use of acid reducers may reduce the laxative effect of magnesium oxide.
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. 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.
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)
Magnesium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after magnesium containing products.
Bisphosphonates
Magnesium can decrease absorption of bisphosphonates.
Cations, including magnesium, can decrease bisphosphonate absorption. Advise patients to separate doses of magnesium and these drugs by at least 2 hours.
Calcium Channel Blockers
Magnesium can have additive effects with calcium channel blockers, although evidence is conflicting.
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, although some contradictory evidence suggests that concurrent use of magnesium with nifedipine does not increase the risk of neuromuscular weakness. High doses of magnesium could theoretically have additive effects with other calcium channel blockers.
Digoxin
Magnesium salts may reduce absorption of digoxin.
Clinical evidence suggests that treatment with oral magnesium hydroxide or magnesium trisilicate reduces absorption of digoxin from the intestines. This may reduce the blood levels of digoxin and decrease its therapeutic effects.
Potassium-Sparing Diuretics
Potassium-sparing diuretics decrease excretion of magnesium, possibly increasing magnesium levels.
Potassium-sparing diuretics also have magnesium-sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics. Theoretically, increased magnesium levels could result from concomitant use of potassium-sparing diuretics and magnesium supplements.
Quinolone Antibiotics
Magnesium decreases absorption of quinolones.
Magnesium can form insoluble complexes with quinolones and decrease their absorption. Advise patients to take these drugs at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
Skeletal Muscle Relaxants
Parenteral magnesium alters the pharmacokinetics of skeletal muscle relaxants, increasing their effects and accelerating the onset of effect.
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. Magnesium also has vasodilatory actions and increases cardiac output, allowing a greater amount of muscle relaxant to reach the motor end plate. 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). 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. 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. It does not affect the activity of subsequently administered neostigmine.
Sulfonylureas
Magnesium increases the systemic absorption of sulfonylureas, increasing their effects and side effects.
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. A similar interaction occurs between magnesium hydroxide and glipizide. 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.
Tetracycline Antibiotics
Magnesium decreases absorption of tetracyclines.
Magnesium can form insoluble complexes with tetracyclines in the gut and decrease their absorption and antibacterial activity. Advise patients to take these drugs 1 hour before or 2 hours after magnesium supplements.
Anticoagulant/Antiplatelet Drugs
Theoretically, magnesium may have antiplatelet effects, but the evidence is conflicting.
In vitro evidence shows that magnesium sulfate inhibits platelet aggregation, even at low concentrations. Some preliminary clinical evidence shows that infusion of magnesium sulfate increases bleeding time by 48% and reduces platelet activity. However, other clinical research shows that magnesium does not affect platelet aggregation, although inhibition of platelet-dependent thrombosis can occur.
Gabapentin (Neurontin)
Gabapentin absorption can be decreased by magnesium.
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%. Advise patients to take gabapentin at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
Sevelamer (Renagel, Renvela)
Sevelamer may increase serum magnesium levels.
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.
