Amlodipine is used with or without other medications to
treat high blood pressure. Lowering high blood pressure helps prevent
strokes, heart attacks, and kidney problems. Amlodipine belongs to a class
of drugs known as calcium channel blockers. It works by relaxing blood
vessels so blood can flow more easily.
Amlodipine is also used to prevent certain types of
chest pain (angina). It may help to increase your ability to exercise and
decrease the frequency of angina attacks. It should not be used to treat
attacks of chest pain when they occur. Use other medications (such as
sublingual nitroglycerin) to relieve attacks of chest pain as directed by
your doctor.
Read the Patient Information Leaflet if available from
your pharmacist before you start taking amlodipine and each time you get a
refill. If you have any questions, ask your doctor or
pharmacist.
Take this medication by mouth with or without food as
directed by your doctor, usually once daily.
