The Telvilite H 40mg/12.5mg Tablet aids in the management of hypertension. Telmisartan and hydrochlorothiazide are the two medications that make up the Telvilite H 40mg/12.5mg Tablet. It is typically used when blood pressure cannot be adequately controlled by a single medication. In order to facilitate easier blood flow, telmisartan relaxes and widens your blood vessels. Your blood pressure will drop as a result. As a diuretic (water pill), hydrochlorothiazide lowers blood pressure by increasing urine production. Controlling your blood pressure lowers your chances of kidney issues, heart attacks, and strokes. For the medication to work, it must be taken as directed on a regular basis.
