Generic name: Amlodipine besylate
Brand names: Norvasc
Why is Norvasc prescribed?
Norvasc is prescribed for angina, a condition characterized by episodes of crushing chest pain that usually results from a lack of oxygen in the heart muscle due to clogged arteries. Norvasc is also prescribed for high blood pressure. It is a type of medication called a calcium channel blocker. These drugs dilate blood vessels and slow the heart to reduce blood pressure and the pain of angina.
Most important fact about Norvasc
If you have high blood pressure, you must take Norvasc regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Norvasc; and you must continue taking it even if you are feeling well. Norvasc does not cure high blood pressure; it merely keeps it under control.
What side effects may occur?
Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Norvasc.
- More common side effects may include:
Dizziness, fatigue, flushing, fluid retention and swelling, headache, palpitations (fluttery or throbbing heartbeat)
Why should Norvasc not be prescribed?
If you are sensitive to or have ever had an allergic reaction to Norvasc, do not take Norvasc.
Special warnings about Norvasc
Check with your doctor before you stop taking Norvasc, as a slow reduction in the dose may be needed.

Although very rare, if you have severe heart disease, you may experience an increase in frequency and duration of angina attacks, or even have a heart attack, when you are starting on Norvasc or your dosage is increased.
