Drug and food interactions


ferrous fumarate food

Applies to: ascorbic acid/ferrous fumarate

Food may reduce the absorption and blood levels of ferrous fumarate. In addition, some oral medications can also interfere with ferrous fumarate absorption into the bloodstream, which may make the medication less effective in treating your condition. Likewise, ferrous fumarate may interfere with the absorption of other orally administered medications. You should take ferrous fumarate on an empty stomach at least one hour before or two hours after a meal. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Talk to your doctor or pharmacist if you have questions about how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
