This report displays the potential drug interactions for the following 2 drugs:
- alendronate
- Mynatal PN (multivitamin, prenatal)
Interactions between your drugs
multivitamin, prenatal alendronate
Applies to: Mynatal PN (multivitamin, prenatal) and alendronate
ADJUST DOSING INTERVAL: Products containing aluminum, calcium, magnesium and other polyvalent cations such as antacids or vitamin with mineral supplements are likely to interfere with the gastrointestinal absorption of oral bisphosphonates. For example, the bioavailability of tiludronate has been shown to decrease 80% during simultaneous administration with calcium, and 60% when aluminum- or magnesium-containing antacids were administered one hour before tiludronate.
MANAGEMENT: Antacids or other oral medications containing aluminum, calcium, magnesium and other polyvalent cations should be administered at least 30 minutes after the bisphosphonate dose.

Drug and food interactions
multivitamin, prenatal food
Applies to: Mynatal PN (multivitamin, prenatal)
ADJUST DOSING INTERVAL: Concomitant use of some oral medications may reduce the bioavailability of orally administered iron, and vice versa.
Food taken in conjunction with oral iron supplements may reduce the bioavailability of the iron. However, in many patients intolerable gastrointestinal side effects occur necessitating administration with food.
MANAGEMENT: Ideally, iron products should be taken on an empty stomach (i.e., at least 1 hour before or 2 hours after meals), but if this is not possible, administer with meals and monitor the patient more closely for a subtherapeutic effect. Some studies suggest administration of iron with ascorbic acid may enhance bioavailability. In addition, administration of oral iron products and some oral medications should be separated whenever the bioavailability of either agent may be decreased. Consult the product labeling for specific separation times and monitor clinical responses as appropriate.

alendronate food
Applies to: 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.
