Iron supplements interact with a long list of drugs used to treat a variety of conditions. Cholesterol -lowering drugs including cholestyramine and colestipol interfere with the absorption of iron. So do acid blockers like ranitidine (Zantac), famotidine (Pepcid), and cimetidine (Tagamet). Conversely, iron decreases the absorption of some drugs including antibiotics like quinolones and tetracyclines and ACE inhibitors that treat high BP. Iron may reduce blood levels of thyroid replacement hormone (Levothyroxine) and Parkinson's treatments like carbidopa and levodopa (Sinemet). Birth control pills may increase blood levels of iron. Check your multivitamin. It may contain iron that can interfere with drugs you are taking. If you must take iron, ask your doctor or pharmacist how many hours before or after you should take it if you are on such medications.
