Quinapril is used to treat high blood pressure and heart failure. It decreases certain chemicals that tighten the blood vessels so that blood flows more smoothly and the heart can pump more efficiently. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How To Use
Quinapril comes as a tablet to take by mouth. It is usually taken once or twice a 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. 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.
