What is hydrochlorothiazide and benazepril?
Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.
Benazepril is an ACE inhibitor. ACE stands for angiotensin converting enzyme. Benazepril lowers blood pressure and also relieves symptoms of fluid retention.
Hydrochlorothiazide and benazepril is a combination medicine used to treat hypertension (high blood pressure).
Hydrochlorothiazide and benazepril may also be used for purposes not listed in this medication guide.
