LISINOPRIL is an antihypertensive (blood pressure lowering agent) known as an ACE inhibitor. Lisinopril controls high blood pressure (hypertension) by relaxing blood vessels; it is not a cure. High blood pressure levels can damage your kidneys, and may lead to a stroke or heart failure. Lisinopril also helps to treat patients with heart failure (heart does not pump strongly enough). Generic lisinopril tablets are available.

Lisinopril may increase the risk of dangerous allergic reactions. Before taking lisinopril, tell your doctor if you have ever had an allergic reaction that involved swelling of your lips, face, tongue, or throat or difficulty breathing. Seek emergency medical attention if you develop any of these symptoms while taking lisinopril.

Do not take lisinopril in pregnancy or planning a pregnancy. When used during the second and third trimesters of pregnancy, lisinopril can cause injury and even death to the developing fetus. Notify your doctor immediately if you think you might be pregnant.
