telmisartan

What is the most important information I should know about telmisartan?

If you have diabetes, do not take telmisartan with any medicine that contains aliskiren (a blood pressure medicine).

What is telmisartan?

Telmisartan is an angiotensin II receptor blocker (sometimes called an ARB) that is used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack.

Telmisartan 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.

Telmisartan may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking telmisartan?

If you have diabetes, do not take telmisartan with any medicine that contains aliskiren (a blood pressure medicine).

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

Tell your doctor if you have ever had:

• a heart condition other than one being treated with telmisartan;
• liver disease;
• kidney disease (or if you are on dialysis); or
• if you are on a low-salt diet.

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.

How should I take telmisartan?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

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

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.

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.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
