Valsartan (Diovan) is a member of a class of drugs known as angiotensin-II receptor blockers (ARBs). These medications are often used to treat hypertension (high blood pressure) and heart failure.
In people with heart failure, Valsartan also reduces the likelihood of having emergency heart issues and helps people live for longer post heart attack. This medication works by relaxing the blood vessels so blood can flow more easily through the veins, which lowers blood pressure and helps to prevent heart attacks, strokes, and kidney problems. However, along with the benefits of this medication, there are common and serious symptoms.
