What is Norvasc?

Norvasc (amlodipine) belongs to a group of drugs called calcium channel blockers. Norvasc relaxes (widens) blood vessels and improves blood flow.

Norvasc is used to treat high blood pressure (hypertension) or chest pain (angina) and other conditions caused by coronary artery disease. This medication is for use in adults and children who are at least 6 years old.

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

Important information

Before taking Norvasc, tell your doctor if you have congestive heart failure or liver disease.

Drinking alcohol can further lower your blood pressure and may increase certain side effects of Norvasc.

If you are being treated for high blood pressure, keep using Norvasc even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

If you are also taking a beta-blocker drug (such as Betapace, Blocadren, Corgard, Coreg, Inderal, InnoPran, Lopressor, Normodyne, Tenoretic, Tenormin, Toprol, Trandate, Zebeta, and others) do not suddenly stop using the beta-blocker without first talking to your doctor.
