Lisinopril can cause serious (possibly fatal) harm to an unborn baby if used during pregnancy. 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, tell your doctor right away.
This medication is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains two medications: lisinopril and hydrochlorothiazide. Lisinopril is an ACE inhibitor and works by relaxing blood vessels so that blood can flow more easily. Hydrochlorothiazide is a "water pill" (diuretic) that causes you to make more urine, which helps your body get rid of extra salt and water.
This product is used when one drug is not controlling your blood pressure. Your doctor may direct you to take the individual medications first, and then switch you to this combination product. Do not continue taking the individual medications (lisinopril and/or hydrochlorothiazide) after you start this medication.
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.
