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 two medications, quinapril and hydrochlorothiazide. Quinapril belongs to a class of drugs known as ACE inhibitors. It works by relaxing blood vessels so blood can flow more easily. Hydrochlorothiazide (or "The thiazide diuretic") increases the amount of urine you make, removing extra water and salt from your body. These medications are used together when one drug is not controlling your blood pressure.
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.
This medication may also be used to treat congestive heart failure.
