Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from
absorbing too much salt, which can cause fluid retention.
Candesartan is in a group of drugs called angiotensin II receptor antagonists. Candesartan
keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
The combination of candesartan and hydrochlorothiazide is used to treat high blood pressure
(hypertension).
Candesartan and hydrochlorothiazide may also be used for other purposes not listed in this
medication guide.
