Valsartan Hydrochlorothiazide Tablets can be taken for a long period of time if blood pressure is well controlled during use and side effects are not obvious. Valsartan Hydrochlorothiazide Tablets is a combination antihypertensive tablet, including valsartan and hydrochlorothiazide, which is not usually used as an initial medication, and is generally indicated for the control of high blood pressure that is not well controlled with a single medication. Valsartan hydrochlorothiazide tablets are a combination drug consisting of valsartan, an angiotensin II receptor antagonist, and hydrochlorothiazide, a diuretic, which work synergistically to control mild to moderate essential hypertension. Common adverse effects of the drug can cause elevated serum urea nitrogen levels, as well as nasopharyngitis, and serious adverse effects may cause hepatitis, angle-closure glaucoma, renal impairment, and angioedema.
