Norvasc

Generic name: Amlodipine
Dosage form: oral tablet (2.5 mg; 5 mg; 10 mg)
Drug class: Calcium channel blocking agents

Usage of Norvasc

Norvasc (amlodipine) belongs to a class of medications called calcium channel blockers. Amlodipine lowers blood pressure by relaxing the blood vessels so the heart does not have to pump as hard.

Norvasc is used to treat certain types of angina (chest pain) and other conditions caused by coronary artery disease (narrowing of the blood vessels that supply blood to the heart).

Norvasc controls chest pain by increasing the supply of blood to the heart. If taken regularly, amlodipine controls chest pain, but it does not stop chest pain once it starts. Your doctor may prescribe a different medication to take when you have chest pain.

Norvasc is also used alone or in combination with other medicines 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.

Norvasc side effects

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

In rare cases, when you first start taking Norvasc, your chest pain 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.

Norvasc may cause serious side effects. Call your doctor at once if you have:

worsening chest pain; or

a light-headed feeling, like you might pass out.

Common Norvasc side effects may include:

dizziness, drowsiness;

swelling of your legs or ankles;

irregular heartbeat;

pounding heartbeats or fluttering in your chest;

muscle stiffness;

uncontrolled muscle movements;

feeling tired;

stomach pain, nausea; or

flushing (sudden warmth, redness, or tingly feeling).

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Before taking Norvasc

You should not take Norvasc if you are allergic to amlodipine.

To make sure Norvasc is safe for you, tell your doctor if you have ever had:

severe narrowing of a certain valve in your heart (aortic stenosis), or other heart problems;

coronary artery disease (clogged arteries); or

liver disease.

It is not known if amlodipine will harm an unborn baby. However, having high blood pressure during pregnancy may cause complications or medical problems in both mother and baby. The benefit of treating hypertension may outweigh any risks to the baby.

Tell your doctor if you are breastfeeding.
