Can I use fosinopril if I am taking antacids?

If you are taking antacids, you can use the blood pressure medication fosinopril, but you should not take the two drugs at the same time. Antacids may interfere with your body's ability to absorb fosinopril.

Take these medications two hours apart from each other. Talk to your doctor about a dosing schedule to avoid interactions between these medications.

Other common heartburn drugs known as acid blockers -- specifically, histamine blockers and proton pump inhibitors -- don't seem to cause this problem. Pepcid AC and Tagamet HB 200 are examples of histamine blockers, also known as H2 blockers; Prevacid 24 HR and Prilosec OTC are examples of proton pump inhibitors, or PPIs.
