Diovan is primarily used to treat high blood pressure (hypertension) in adults and children. It is also prescribed for heart failure, to improve survival after a heart attack, and to protect kidney function in people with diabetes.
Diovan blocks the action of angiotensin II, a natural substance that causes blood vessels to narrow. By preventing this effect, the medication allows blood vessels to relax and widen, making it easier for blood to flow and reducing overall blood pressure.
Diovan should not be used during pregnancy as it may harm an unborn baby. Common side effects may include dizziness, headache, and flu-like symptoms. Patients should inform their doctor about all medications they are taking, as drug interactions can occur. Regular blood pressure monitoring and laboratory tests may be needed during treatment.
