Teleshal is a medicine used to treat a condition called hypertension or high blood pressure. It contains a drug called Telmisartan that helps to lower elevated blood pressure. Hypertension can be dangerous if left untreated, as it can lead to serious health problems. Teleshal works by blocking the action of certain substances that tighten the blood vessels. Telmisartan can help reduce risk of heart attacks, stroke, and other complications in hypertensive patients. Teleshal H fixed dose combination is indicated in adults whose blood pressure is not adequately controlled on telmisartan alone.
