Do not take quinapril if you are pregnant. If you become pregnant while taking quinapril, call your doctor immediately. Quinapril may harm the fetus.
WHY is this medicine prescribed?
Quinapril is used alone or in combination with other medications to treat high blood pressure. It is used in combination with other medications to treat heart failure. Quinapril is in a class of medications called angiotensin-converting enzyme (ACE) inhibitors. It works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly and the heart can pump blood more efficiently.
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
HOW should this medicine be used?
Quinapril comes as a tablet to take by mouth. It is usually taken once or twice a day. To help you remember to take quinapril, take it around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take quinapril exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of quinapril and gradually increase your dose, not more than once every 1 or 2 weeks.
Quinapril controls high blood pressure and heart failure but does not cure them. Continue to take quinapril even if you feel well. Do not stop taking quinapril without talking to your doctor.
