What this medicine is used for
Amlodipine is used to lower high blood pressure (hypertension) or treat angina. It belongs to a group of medicines called calcium channel blockers.
How it works

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
There is not enough information to recommend using amlodipine in children.
