Drug Interaction: Calcium Supplements/Antacids

Co-administration of Alendronate and calcium, antacids, or oral medications containing multivalent cations will interfere with absorption of Alendronate. Therefore, instruct patients to wait at least one-half hour after taking Alendronate before taking any other oral medications.


In clinical studies, the incidence of upper gastrointestinal adverse events was increased in patients receiving concomitant therapy with daily doses of Alendronate greater than 10 mg and aspirin-containing products.

Nonsteroidal Anti-Inflammatory Drugs

Since NSAID use is associated with gastrointestinal irritation, caution should be used during concomitant use with Alendronate.
