What is amlodipine?
Amlodipine is a calcium channel blocker that dilates (widens) blood vessels and improves blood flow.
Amlodipine is used to treat chest pain (angina) and other conditions caused by coronary artery disease.
Amlodipine is also used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack.
Amlodipine is for use in adults and children who are at least 6 years old.
Important information
Before taking amlodipine, tell your doctor if you have congestive heart failure or liver disease.
Drinking alcohol can further lower your blood pressure and may increase certain side effects of amlodipine.
If you are being treated for high blood pressure, keep using amlodipine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
