Diovan HCT Side Effects, Usefull Information, How to Use

Diovan is a mixture of two medicines; hydrochlorothiazide and valsartan. Valsartan belongs to the family of angiotensin receptor blocker which relaxes the blood vessels thus allowing easier blood flow. Meanwhile, hydrochlorothiazide is a diuretic which helps to get rid of excess salt and water in the body by encouraging increased urine production.


Primarily, Diovan is used for treating high blood pressure which in turn helps to prevent kidney problems, heart attacks, and strokes.
