GENERIC NAME: amlodipine besylate
BRAND NAME: Norvasc
GENERIC AVAILABLE: Yes
USES: Chest pain or heart pain (angina) occurs because of insufficient oxygen delivered to the heart muscles. Insufficient oxygen may be a result of coronary artery blockage or spasm, or because of exertion which increases the need of the heart for oxygen in patients with coronary artery narrowing (coronary artery disease or atherosclerosis). Amlodipine is used for the treatment and prevention of angina resulting from coronary spasm as well as from exertion. Amlodipine also is used in the treatment of high blood pressure.
SIDE EFFECTS: Side effects of amlodipine are generally mild and reversible. The two most common side effects are:
Other side effects include:
More serious side effects include:
- increase in the frequency and severity of angina,
- heart attacks, and
- congestive heart failure.
Increase in the frequency and severity of angina or heart attack due to amlodipine happens on rare occasions in patients with severe coronary artery disease when first starting amlodipine, or at the time of an increase in dosage. Excessive lowering of blood pressure during initiation of amlodipine treatment can occur, especially in patients already taking other medications that lower blood pressure. In rare instances, congestive heart failure has been associated with amlodipine, particularly in patients already taking a beta blocker.
