What is Micardis?

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). It is sometimes given together 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.

Important information

Stop using Micardis and tell your doctor right away if you become pregnant. Telmisartan can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.
