What is 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.
Amlodipine and valsartan is usually given after other blood pressure medicines have been tried without success.
Amlodipine and valsartan may also be used for purposes not listed in this medication guide.
Do not use if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away.
