benazepril-hydrochlorothiazide

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.

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.

Drink adequate fluids to prevent from becoming dehydrated. If you are on restricted fluid intake, consult your doctor for further instructions.

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.

Keep 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 4 hours before or at least 4 to 6 hours after either of those drugs.

You may experience dizziness, light-headedness, drowsiness, headache, fatigue, blurred vision, dry cough, or vomiting as your body adjusts to the medication. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
