Why is this medication prescribed? Return to top

The combination of benazepril and hydrochlorothiazide is used to treat high blood pressure. Benazepril 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. Hydrochlorothiazide is in a class of medications called diuretics ('water pills'). It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine.

How should this medicine be used? Return to top

The combination of benazepril and hydrochlorothiazide comes as a tablet to take by mouth. It is usually taken once a day.
