Interactions between your drugs

Moderate

alendronate sucroferric oxyhydroxide

Applies to: Fosamax (alendronate) and sucroferric oxyhydroxide

ADJUST DOSING INTERVAL: Coadministration with sucroferric oxyhydroxide may reduce the oral bioavailability of bisphosphonates. The proposed mechanism is chelation of bisphosphonates to the ferric ion component of sucroferric oxyhydroxide, forming an insoluble complex that is poorly absorbed from the gastrointestinal tract. According to the product labeling for sucroferric oxyhydroxide, an in vitro interaction with alendronate was observed when studied in aqueous solutions that mimic the physico-chemical conditions of the gastrointestinal tract.

MANAGEMENT: Alendronate should be administered at least 1 hour before sucroferric oxyhydroxide. No dosing recommendations are available for use with other bisphosphonates. Patients may follow the manufacturers' suggestion provided in the individual bisphosphonate label regarding use with mineral supplements and other polyvalent cation-containing products (i.e., administer sucroferric oxyhydroxide at least 30 minutes after risedronate, 1 hour after ibandronate, and at least 2 hours before or 2 hours after clodronate, etidronate, or tiludronate).

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.
