BENAZEPRIL/HYDROCHLOROTHIAZIDE - ORAL
COMMON BRAND NAME(S): Lotensin HCT
WARNING: This drug can cause serious harm to an unborn baby (possibly fatal) if used during pregnancy. Therefore, 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, contact your doctor immediately.
USES: This medication is a combination of two drugs, an ACE inhibitor (benazepril) and a "water pill"/diuretic (hydrochlorothiazide). It is used to treat high blood pressure (hypertension). Benazepril works by relaxing blood vessels, causing them to widen. The hydrochlorothiazide diuretic increases the amount of urine you make, therefore decreasing excess water and salt in your body. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.
OTHER USES: 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 and help protect the kidneys from damage due to diabetes.
HOW TO USE: Take this medication by mouth, usually once a day; or as directed by your doctor. You may take this drug with or without food. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day.

The dosage is based on your medical condition and response to therapy. For the treatment of high blood pressure, it may take 2 weeks before the full benefit of this drug occurs or several weeks to months when used for congestive heart failure.
It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.
If you are also taking cholestyramine or colestipol, take benazepril/hydrochlorothiazide at least 2 hours before either of those drugs.
