What is amlodipine?
Amlodipine is in a group of drugs called calcium channel blockers. Amlodipine relaxes (widens) blood vessels and improves blood flow.
Amlodipine is used to treat high blood pressure (hypertension) or chest pain (angina).
Amlodipine may also be used for other purposes not listed in this medication guide.
You should not take this medication if you are allergic to amlodipine.
If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before taking amlodipine, tell your doctor if you have:
- congestive heart failure; or
- liver disease.
If you are also taking a beta-blocker drug (such as Blocadren, Corgard, Inderal, Normodyne, Tenormin, Toprol, Trandate, Zebeta, and others) do not suddenly stop using the beta-blocker without first talking to your doctor. You may need to use less and less before you stop the medication completely. Stopping a beta-blocker too quickly can cause serious heart problems that will not be prevented by amlodipine.
FDA pregnancy category C. Amlodipine may be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether amlodipine passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
Avoid drinking alcohol while taking amlodipine. Alcohol can further lower your blood pressure and may increase some of the side effects of amlodipine.
