For each ingredient in MagnaPower Complex with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Magnesium Stearate15 drug types · 295 drugs

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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence A
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.

Likelihood Probable Evidence B
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.

Likelihood Probable Evidence D
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.

Likelihood Unlikely Evidence B
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.

Likelihood Unlikely Evidence B
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.

Likelihood Possible Evidence B
Magnesium Stearate full monograph & interactions

Sodium Bicarbonate14 drug types · 257 drugs

Aminoglycoside Antibiotics

Theoretically, sodium bicarbonate may increase the risk for hypokalemia in patients receiving aminoglycosides.
Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, when administered intravenously, the most common complication of sodium bicarbonate is hypokalemia. Nephrotoxicity caused by aminoglycosides may lead to increased urinary losses of various electrolytes, including potassium.

Likelihood Possible Evidence D
Amphotericin-B (Abelcet, Others)

Theoretically, sodium bicarbonate may increase the risk for hypokalemia in patients receiving amphotericin B.
Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, when administered intravenously, the most common complication of sodium bicarbonate is hypokalemia. Amphotericin B increases urinary potassium losses due to toxic effects on renal tubular epithelium. Hypokalemia can occur in up to 50% of patients.

Likelihood Possible Evidence D
Aspirin

Theoretically, sodium bicarbonate may reduce the levels and clinical effects of aspirin.
In humans, oral or intravenous administration of sodium bicarbonate increases salicylate elimination. Although the exact mechanism of this effect is not clear, some researchers hypothesize that sodium bicarbonate increases urinary pH, which increases salicylate ionization and subsequent excretion by the kidneys. In patients with urine pH of about 5.5, renal clearance of salicylate is approximately 55 mL/min. When urine pH is increased with oral sodium bicarbonate to about 7.5, renal clearance of salicylate increases to approximately 100 mL/min. Similarly, urine alkalinization with sodium bicarbonate increases the mean total body clearance of salicylate by approximately 60% compared with urine acidification.

Likelihood Probable Evidence B
Beta-Adrenergic Agonists

Theoretically, sodium bicarbonate may increase the risk for hypokalemia in patients taking beta-adrenergic agonists.
Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common adverse effect of intravenous sodium bicarbonate is hypokalemia. Oral, parenteral, or inhaled beta-adrenergic agonists can reduce serum potassium levels, especially during acute use of high doses.

Likelihood Possible Evidence D
Cefpodoxime Proxetil (Vantin)

Theoretically, sodium bicarbonate might reduce the levels and clinical effects of cefpodoxime.
Cefpodoxime proxetil is an oral prodrug that is de-esterified in the intestine to the active drug cefpodoxime. Drugs or supplements that increase gastric pH can inhibit the activation of cefpodoxime proxetil and reduce the peak plasma concentrations of cefpodoxime. In humans, taking sodium bicarbonate 12.6 grams orally along with cefpodoxime proxetil 200 mg reduces peak plasma concentrations and area under the plasma concentration-time curve (AUC) of cefpodoxime by 35% to 50%.

Likelihood Probable Evidence B
Chlorpropamide (Diabinese)

Theoretically, sodium bicarbonate might reduce the levels and clinical effects of chlorpropamide.
The elimination of chlorpropamide by the kidneys depends strongly on urine pH. At a pH of 5, the renal clearance of chlorpropamide ranges from 0.5 to 3 mL/hr. At a pH of 8, renal clearance of chlorpropamide ranges from 500 to 1000 mL/hr. When taken in combination with oral sodium bicarbonate, the elimination half-life of chlorpropamide is shortened from 49.7 to 12.8 hours and urinary excretion of chlorpropamide is increased four-fold.

Likelihood Probable Evidence B
Cisplatin (Platinol-Aq)

Theoretically, sodium bicarbonate may increase the risk of hypokalemia in patients receiving cisplatin.
Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common complication of intravenous sodium bicarbonate is hypokalemia. Cisplatin can cause renal tubular damage, with increased losses of electrolytes including potassium.

Likelihood Possible Evidence D
Corticosteroids

Theoretically, sodium bicarbonate may increase the risk of hypokalemia in patients taking corticosteroids.
Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common intravenous complication of sodium bicarbonate is hypokalemia. Some glucocorticoids (corticosteroids) can also cause hypokalemia by causing sodium retention, resulting in compensatory renal potassium excretion. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.

Likelihood Possible Evidence D
Loop Diuretics

Theoretically, sodium bicarbonate may increase the risk of hypokalemia in patients taking loop diuretics.
Loop diuretics increase urinary potassium excretion. Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common complication of intravenous sodium bicarbonate is hypokalemia.

Likelihood Possible Evidence D
Methylxanthines

Theoretically, sodium bicarbonate may increase the risk of hypokalemia in patients taking methylxanthines.
Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common complication of intravenous sodium bicarbonate is hypokalemia. Theophylline and related drugs can reduce serum potassium levels, possibly by increasing intracellular uptake of potassium. Hypokalemia is most likely to occur after acute overdose of these drugs. However, reduced potassium levels can occur with therapeutic doses, and the incidence and degree of hypokalemia increases with increasing serum theophylline levels.

Likelihood Possible Evidence D
Pseudoephedrine (Sudafed)

Theoretically, sodium bicarbonate may increase levels and adverse effects of pseudoephedrine.
In humans, intravenous or oral administration of sodium bicarbonate can increase urinary pH. Clinical evidence shows that urine alkalinization increases the serum elimination half-life of pseudoephedrine by approximately 10-fold. In one patient with persistently alkaline urine, treatment with pseudoephedrine resulted in hallucinations and personality changes.

Likelihood Probable Evidence B
Sodium-Containing Drugs

Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related adverse effects.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium bicarbonate, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, sodium bicarbonate may increase the risk of hypokalemia in patients taking stimulant laxatives.
Long-term use of stimulant laxatives, or acute use of high doses (e.g., in bowel-cleansing regimens), can result in potassium loss and hypokalemia. Orally, use of excessive sodium bicarbonate (such as intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common complication of intravenous sodium bicarbonate is hypokalemia.

Likelihood Possible Evidence D
Thiazide Diuretics

Theoretically, sodium bicarbonate may increase the risk of hypokalemia in patients taking thiazide diuretics.
Thiazide diuretics increase urinary potassium excretion. Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common complication of intravenous sodium bicarbonate is hypokalemia.

Vanadyl Sulfate2 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, vanadium might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
In vitro research shows that the sodium orthovanadate form of vanadium prolongs clotting time, likely through inhibition of thrombin and factor Xa.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, vanadium might increase the risk of hypoglycemia when taken with antidiabetes drugs.
A few very small clinical studies in patients with type 2 diabetes show that the vanadyl sulfate form of vanadium increases insulin sensitivity and might lower blood glucose levels.

Likelihood Probable Evidence B
Vanadyl Sulfate full monograph & interactions

Chromium Picolinate5 drug types · 178 drugs

Antidiabetes Drugs

Theoretically, chromium may have additive effects with antidiabetic agents and increase the risk of hypoglycemia.
Some research shows that taking chromium might lower blood glucose levels, especially in patients with poorly controlled type 2 diabetes.

Likelihood Possible Evidence A
Insulin

Theoretically, concomitant use of chromium and insulin might increase the risk of hypoglycemia.
In clinical research, chromium has been shown to increase insulin sensitivity,

Likelihood Possible Evidence B
Levothyroxine (Synthroid, Others)

Chromium might bind levothyroxine in the intestinal tract and decrease levothyroxine absorption.
Clinical research in healthy volunteers shows that taking chromium picolinate 1000 mcg with levothyroxine 1 mg decreases serum levels of levothyroxine by 17% when compared to taking levothyroxine alone. Advise patients to take levothyroxine at least 30 minutes before or 3-4 hours after taking chromium.

Likelihood Probable Evidence B
Aspirin

Theoretically, aspirin might increase chromium absorption.
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood.

Likelihood Possible Evidence D
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)

NSAIDs might increase chromium levels in the body.
Drugs that are prostaglandin inhibitors, such as NSAIDs, seem to increase chromium absorption and retention.

Likelihood Possible Evidence D
Chromium Picolinate full monograph & interactions

Calcium Carbonate18 drug types · 168 drugs

Ceftriaxone (Rocephin)

Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction. So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.

Likelihood Probable Evidence D
Dolutegravir (Tivicay)

Calcium seems to reduce levels of dolutegravir.
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation.

Likelihood Probable Evidence B
Elvitegravir (Vitekta)

Calcium seems to reduce levels of elvitegravir.
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation.

Likelihood Probable Evidence B
Aluminum

Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease. However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption.

Likelihood Possible Evidence B
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Calcium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and calcium can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, calcium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Calcium reduces the absorption of bisphosphonates.
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates.

Likelihood Probable Evidence C
Calcipotriene (Dovonex)

Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. However, one retrospective analysis of clinical data suggests that intravenous calcium does not increase the risk of dysrhythmias or mortality in patients receiving digoxin.

Likelihood Possible Evidence B
Diltiazem (Cardizem, Others)

Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.

Likelihood Probable Evidence D
Levothyroxine (Synthroid, Others)

Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Advise patients to take levothyroxine and calcium supplements at least 4 hours apart. Calcium reduces levothyroxine absorption, probably by forming insoluble complexes. Calcium carbonate supplements reduce effectiveness of levothyroxine in patients with hypothyroidism.

Likelihood Probable Evidence B
Lithium

Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients. Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.

Likelihood Possible Evidence B
Quinolone Antibiotics

Calcium seems to reduce the absorption of quinolone antibiotics.
Advise patients to take oral quinolones at least 2 hours before or 4-6 hours after calcium supplements or calcium-fortified foods. Taking calcium at the same time as oral quinolones can reduce quinolone absorption. Calcium binds to quinolones in the gut.

Likelihood Probable Evidence B
Raltegravir (Isentress)

Calcium may reduce levels of raltegravir.
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir. However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure.

Likelihood Possible Evidence B
Sotalol (Betapace)

Calcium seems to reduce the absorption of sotalol.
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes.

Likelihood Possible Evidence B
Tetracycline Antibiotics

Calcium seems to reduce the absorption of tetracycline antibiotics.
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut.

Likelihood Probable Evidence C
Thiazide Diuretics

Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Thiazides reduce calcium excretion by the kidneys. Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.

Likelihood Probable Evidence C
Verapamil (Calan, Others)

Theoretically, calcium may reduce the therapeutic effects of verapamil.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.

Likelihood Probable Evidence D
Calcium Channel Blockers

Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects. But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers.
