What is TEVA-AMLODIPINE used for?
TEVA-AMLODIPINE is used in adults and children 6 years of age and older to:

How does TEVA-AMLODIPINE work?

TEVA-AMLODIPINE relaxes your blood vessels, which lets your blood flow more easily. This helps to lower your blood pressure.
TEVA-AMLODIPINE controls chest pain by improving the supply of blood and oxygen to the heart. This reduces the amount of work that your heart has to do.
