Co-Diovan 160/25 is a prescription medication manufactured by Novartis, containing a combination of valsartan (160mg) and hydrochlorothiazide (25mg). It is used to treat high blood pressure (hypertension). The package contains 28 film-coated tablets. This medication combines two active ingredients: valsartan, which belongs to a class of drugs called angiotensin receptor blockers (ARBs), and hydrochlorothiazide, which is a diuretic (water pill). The combination works to lower blood pressure by relaxing blood vessels and removing excess fluid from the body. This medicine requires a prescription and should be taken as directed by your healthcare provider. The tablets are film-coated and come in a clearly labeled box with the Novartis logo.
