Amlodipine (Norvasc) is used alone or in combination with other medications to treat high blood pressure and chest pain (angina). It lowers blood pressure by relaxing the blood vessels so the heart does not have to pump as hard. It controls chest pain by increasing the supply of blood to the heart. If taken regularly, amlodipine controls chest pain, but it does not stop chest pain once it starts.

Amlodipine controls high blood pressure and chest pain (angina) but does not cure them. Continue to take amlodipine even if you feel well. Do not stop taking amlodipine without talking to your doctor.

• Tell your doctor if you have or have ever had heart failure or liver disease.
