Drug Interaction Report

Risedronate and zinc acetate should not be taken orally at the same time. Products that contain magnesium, aluminum, calcium, iron, and/or other minerals may interfere with the absorption of risedronate into the bloodstream and reduce its effectiveness. You should take zinc acetate at least 30 minutes after the risedronate dose. Talk to a healthcare professional if you are not sure whether a product contains something that could potentially interact with your medication or if you have questions on 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.

You may experience reduced absorption of zinc acetate in the presence of certain foods. Bread, bran, hard boiled eggs, coffee, and milk may significantly decrease the absorption of zinc acetate. Take zinc acetate on an empty stomach 1 hour before or 2 hours after a meal unless otherwise directed by your doctor. This will make it easier for your body to absorb the medication. Zinc acetate may be taken with small amounts of protein such as meat.

Food may reduce the absorption of risedronate, which may lead to lower blood levels of the medication and possibly reduced effectiveness. You should take risedronate first thing in the morning, at least 30 minutes before you eat or drink anything or take any other medication. Take each dose with a full glass (6 to 8 ounces) of water, and use only plain water (not mineral or vitamin water). Do not take risedronate if you cannot sit upright or stand for at least 30 minutes. Because risedronate can cause irritation and ulcer in the stomach or esophagus (the tube that connects your mouth and stomach), you will need to stay upright for at least 30 minutes after taking this medication. Talk to your doctor or pharmacist if you have questions on 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.
