Hydrochlorothiazide is a diuretic (water pill). Olmesartan is an angiotensin II receptor blocker (sometimes called an ARB blocker).

Hydrochlorothiazide and olmesartan is a combination medicine used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack.

Hydrochlorothiazide and olmesartan is usually given after other blood pressure medicines did not work or have stopped working.

Hydrochlorothiazide and olmesartan may also be used for purposes not listed in this medication guide.
