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 in a group of drugs called angiotensin II receptor antagonists. Telmisartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

The combination of hydrochlorothiazide and telmisartan is used to treat high blood pressure (hypertension).

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