Telmisartan — Uses, Dosage, Side Effects & Safety

Drug class: Angiotensin II Receptor Blocker (ARB)

Overview

Telmisartan is a prescription medication used to treat high blood pressure (hypertension) and to reduce the risk of cardiovascular events such as stroke and heart attack in certain patients. By lowering blood pressure, telmisartan helps protect the heart, kidneys, and blood vessels from damage. Telmisartan works by blocking the action of a substance in the body called angiotensin II, which causes blood vessels to tighten. When angiotensin II is blocked, blood vessels relax and widen, making it easier for blood to flow and lowering blood pressure. Key points for patients: Telmisartan is usually taken once daily, with or without food. It is important to take it regularly, even if you feel well, as high blood pressure often has no symptoms. Do not stop taking telmisartan without talking to your doctor, as this may increase your risk of serious heart problems.
