Interactions between your drugs

Moderate

torsemide alendronate

Applies to: torsemide and Fosamax (alendronate)

MONITOR: Coadministration of bisphosphonates and loop diuretics may potentiate the risk of hypocalcemia. Bisphosphonates alone often cause mild, asymptomatic hypocalcemia via inhibitive effects on bone resorption and possibly chelation of blood calcium. These effects may be additive with those of loop diuretics, which tend to increase the urinary excretion of calcium.

MANAGEMENT: Caution is advised if bisphosphonates are coadministered with loop diuretics. Renal function as well as serum calcium levels should be monitored during and after treatment, since the effects of bisphosphonates can continue for many weeks after discontinuation. Patients and clinicians should be alert to signs and symptoms of clinical hypocalcemia such as muscle spasm, carpopedal spasm, laryngeal spasm, tetany, convulsions, mental changes (irritability, depression, psychosis), increased intracranial pressure, papilledema, QT interval prolongation, and cardiac arrhythmias.

Drug and food interactions

Moderate

alendronate food

Applies to: Fosamax (alendronate)

ADJUST DOSING INTERVAL: Food significantly decreases the bioavailability of alendronate, possibly to negligible levels.

MANAGEMENT: Alendronate should be administered with 6 to 8 ounces of plain water, at least 30 minutes before the first food, beverage, or medication of the day. Patients should remain upright for at least 30 minutes following administration of alendronate.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
