WHAT ARE POSSIBLE DRUG INTERACTIONS WITH LEVITRA?
Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. LEVITRA and other medicines may affect each other. LEVITRA can cause your blood pressure to drop suddenly to an unsafe level if it is taken with medicines called nitrates. With a sudden drop in blood pressure, you can get dizzy, faint, or have a heart attack or stroke.
