This Olmo CT 40mg/12.5mg Tablet combines two medications. It aids in the management of hypertension in a variety of ways. Heart attacks, strokes, and renal failure can result from untreated high blood pressure. Olmesartan and chlorthalidone are the two medications that make up the Olmo CT 40mg/12.5mg Tablet combination. It is typically used when blood pressure cannot be adequately controlled by a single medication. Olmesartan facilitates easier blood flow by relaxing and enlarging your blood vessels. Your blood pressure will drop as a result. Chlorthalidone is a diuretic, or water pill, that 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. Taking this medication normally has no immediate effects on you, but it keeps you healthy over time.
