Diovan Side Effects

Diovan (valsartan) is an angiotensin II receptor antagonist. Valsartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Diovan is used to treat high blood pressure (hypertension)in adults and children who are at least 6 years old. Diovan is also used in adults to treat heart failure, and to lower the risk of death after a heart attack. It is sometimes given together with other blood pressure medications.

You should not use Diovan if you are allergic to valsartan.

To make sure Diovan is safe for you, tell your doctor if you have any of these other conditions:

  • kidney disease;
  • liver disease;
  • heart disease;
  • if you are dehydrated; or
  • if you have ever had a severe allergic reaction to any blood pressure medication.
