ENALAPRIL/HYDROCHLOROTHIAZIDE – ORAL
COMMON BRAND NAME(S): Vaseretic
WARNING: This drug can cause serious (possibly fatal) harm to an unborn baby if used during pregnancy. Therefore, it is important to prevent pregnancy while taking this medication. Consult your doctor for more details and to discuss the use of reliable forms of birth control while taking this medication. If you are planning pregnancy, become pregnant or think you may be pregnant, contact your doctor immediately.
USES: This medication is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains 2 medications, enalapril and hydrochlorothiazide. Enalapril belongs to a class of drugs known as ACE inhibitors. It works by relaxing blood vessels so that blood can flow through the body more easily. Hydrochlorothiazide is a “water pill” (diuretic) and causes your body to get rid of extra salt and water. This effect may increase the amount of urine you make when you first start the medication. It also helps to relax the blood vessels so that blood can flow through the body more easily.
OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
