Generic Norvasc is a calcium-channel blocker. It affects the amount of calcium found in your heart and muscle cells. This results in relaxation of blood vessels, which can reduce the amount of work the heart has to do. Generic Norvasc lowers high blood pressure (hypertension). It also relieves different types of chest pain (angina).
Take Generic Norvasc tablets orally. Follow the directions on the prescription label. Swallow the tablets with a glass of water. You can take the tablets with or without food. Take your doses at regular intervals. Do not take your medicine more often then directed. Do not stop taking except on your prescriber's advice. Elderly patients over 65 years old may have a stronger reaction to this medicine and need smaller doses.

Check your blood pressure and pulse rate regularly; this is important while you are taking amlodipine. Ask your prescriber or health care professional what your blood pressure and pulse rate should be and when you should contact him or her. You may feel dizzy or lightheaded.

To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient. Avoid alcoholic drinks; they can make you more dizzy, increase flushing and rapid heartbeats. Do not suddenly stop taking amlodipine. Ask your prescriber or health care professional how you can gradually reduce the dose.
