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