# Micardis

Generic name: telmisartan [ TEL-mi-SAR-tan ]
Drug class: Angiotensin receptor blockers

Medically reviewed by Philip Thornton, DipPharm. Last updated on Jan 11, 2023.

## What is Micardis?

Micardis is an angiotensin II receptor blocker (sometimes called an ARB). Telmisartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Micardis is used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack.

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.

## Warnings

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 take Micardis with any medicine that contains aliskiren (a blood pressure medicine e.g. Amturnide, Tekturna, Tekamlo, Valturna).

You may also need to avoid taking Micardis with aliskiren if you have kidney disease.

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.

## Before taking this medicine

You should not use Micardis if you are allergic to telmisartan.

To make sure Micardis is safe for you, tell your doctor if you have:

- a heart condition other than one being treated with Micardis;

- liver disease;

- kidney disease (or if you are on dialysis); or

- if you are on a low-salt diet.

Do not use if you are pregnant. Stop using the medicine 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 plan to get pregnant, ask your doctor for a safer medicine to use before and during pregnancy. Having high blood pressure during pregnancy may cause complications in the mother and the baby.

You should not breastfeed while using this medicine.

## How should I take Micardis?

Take Micardis exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Take Micardis at the same time each day, with or without food.

Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking Micardis.

It may take 2 to 4 weeks before your blood pressure is under control. Keep using this medicine even if you feel well. High blood pressure often has no symptoms.

You may need to use blood pressure medicine for the rest of your life. Treatment may also include diet, exercise, lowering cholesterol, not smoking, and controlling diabetes.

Your blood pressure will need to be checked often. Your liver or kidney function may also need to be checked.

Store at room temperature away from moisture and heat. Keep the tablets in their original package or container, along with any packet or canister of moisture-absorbing preservative.

Keep this medicine in its original packaging until you're ready to take a tablet. Tear or cut one tablet blister from the package, peel back the paper liner, and push the tablet through the foil.

## Dosing information

Usual Adult Dose for Hypertension:

Initial dose: 40 mg orally once a day
Maintenance dose: 40 to 80 mg orally once a day
Comments: Most of the antihypertensive effect is present within 2 weeks; maximum blood pressure reduction at a given dose is generally observed within 4 weeks of starting that dose.

Usual Adult Dose for Cardiovascular Risk Reduction:

80 mg orally once a day
Comments: It is unknown whether doses lower than 80 mg are effective in reducing the risk of cardiovascular morbidity and mortality.
-When initiating this drug for cardiovascular risk reduction, monitoring of blood pressure is recommended, and if appropriate, adjustment of other medications that lower blood pressure.
Use: Reduction of risk of myocardial infarction, stroke, or death from cardiovascular causes in patients 55 years or older at high risk of developing major cardiovascular events who are unable to take angiotensin-converting enzyme (ACE) inhibitors. High risk for cardiovascular events can be evidenced by a history of coronary artery disease, peripheral arterial disease, stroke, transient ischemic attack, or high-risk diabetes (insulin-dependent or non-insulin dependent) with evidence of end-organ damage.
