Exforge is used alone or together with other medicines to treat high blood pressure (hypertension) in adults. Lowering blood pressure may lower your risk of a stroke or heart attack.

Exforge contains a combination of amlodipine and valsartan. Amlodipine is a calcium channel blocker. It works by relaxing the muscles of your heart and blood vessels.

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

Do not use Exforge if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away.

If you have diabetes, do not use Exforge together with any medication that contains aliskiren (such as Amturnide, Tekturna, Valturna, or Tekamlo).

In rare cases, Exforge can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness especially if you also have fever, unusual tiredness, and dark colored urine.

Do not use potassium supplements or salt substitutes while you are taking Exforge, unless your doctor has told you to.

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
