Amlodipine is used for:
Treating high blood pressure and angina (chest pain). It may be used alone or with other medicines. It may also be used for other conditions as determined by your doctor.
Amlodipine is a calcium channel blocker. It works by widening blood vessels to reduce chest pain and high blood pressure. It also widens arteries in the heart, which increases blood flow to the heart.

- you are allergic to any ingredient in amlodipine
Contact your doctor or health care provider right away if any of these apply to you.
