Tell your doctor if you are pregnant or plan to become pregnant. Do not take telmisartan if you are pregnant. If you become pregnant while you are taking telmisartan, stop taking telmisartan and call your doctor immediately. Telmisartan may cause death or serious injury to the fetus when taken in the last 6 months of pregnancy.
WHY is this medicine prescribed?
Telmisartan is used alone or in combination with other medications to treat high blood pressure. Telmisartan is also used to decrease the chance of heart attack, stroke, or death in people 55 years of age or older who are at high risk for cardiovascular disease. Telmisartan is in a class of medications called angiotensin II receptor antagonists. It works by blocking the action of certain natural substances that tighten the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently.
HOW should this medicine be used?
Telmisartan comes as a tablet to take by mouth. It is usually taken once a day with or without food. To help you remember to take telmisartan, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take telmisartan exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Telmisartan tablets come in individual blister packs that can be opened by peeling back the paper layer from the foil and pushing the tablet through the foil. Do not open a blister pack until you are ready to swallow the tablet it contains.
Your doctor may start you on a low dose of telmisartan and gradually increase your dose.
Telmisartan controls high blood pressure but does not cure it. Your blood pressure may decrease during the first 2 weeks of your treatment, but it may take 4 weeks for you to notice the full benefit of telmisartan. Continue to take telmisartan even if you feel well. Do not stop taking telmisartan without talking to your doctor.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
Are there OTHER USES for this medicine?
Telmisartan is also used sometimes to treat congestive heart failure (condition in which the heart is unable to pump enough blood to the rest of the body) and diabetic nephropathy (kidney disease in people with diabetes and high blood pressure). Talk to your doctor about the possible risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
