Micardis (telmisartan) is an angiotensin II receptor antagonist. Telmisartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
Micardis is used to treat high blood pressure (hypertension), sometimes in combination with other blood pressure medications.
Micardis is also used to reduce the risk of stroke, heart attack, or death from heart problems in people who are at least 55 years old with risk factors for serious heart disorders.
Read the Patient Information Leaflet if available from your pharmacist before you start taking telmisartan and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
