What is hydrochlorothiazide and telmisartan (Micardis HCT)?

Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.

Telmisartan is an angiotensin II receptor antagonist. Azilsartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Hydrochlorothiazide and telmisartan is a combination medicine used to treat high blood pressure (hypertension).

Hydrochlorothiazide and telmisartan is usually given after other hypertension medications have been tried without successful treatment.

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