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), 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.
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.
If you have diabetes, do not use Micardis together with any medication that contains aliskiren (Amturnide, Tekturna, Tekamlo, Valturna).
In rare cases, Micardis can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness especially if you also have fever, unusual tiredness, and dark colored urine.

If you have diabetes, do not use Micardis together with any medication that contains aliskiren (a blood pressure medicine).
You may also need to avoid taking Micardis with aliskiren if you have kidney disease.
To make sure Micardis is safe for you, tell your doctor if you have ever had:
