Amlodipine is also used to treat high blood pressure (hypertension) in adults and children at least 6 years old. Lowering blood pressure may lower your risk of a stroke or heart attack.

Amlodipine may also be used for purposes not listed in this medication guide.

What are the possible side effects of amlodipine (Katerzia, Norvasc)?

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

In rare cases, when you first start taking amlodipine, your angina may get worse or you could have a heart attack. Seek emergency medical attention or call your doctor right away if you have symptoms such as: chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating.

The benefit of treating hypertension may outweigh any risks to the baby.
