Diovan HCT (Valsartan/HCTZ)(℞) Prescription Required - Diovan HCT is also marketed as Co Diovan HCT
Diovan HCT (Valsartan/HCTZ) Dosage and Side Effects
DIOVAN HCT lowers high blood pressure. DIOVAN HCT is used to treat people after a heart attack when an angiotensin-converting enzyme (ACE) inhibitor, considered part of standard therapy for this condition, is not appropriate. DIOVAN HCT is used in patients with chronic heart failure, when they are unable to tolerate the standard treatment with medications called ACE inhibitors. There is no evidence that DIOVAN HCT provides added benefit when it is used with ACE inhibitors.
