What is amlodipine?
Amlodipine is a calcium channel blocker that dilates (widens) blood vessels and improves blood flow.
Amlodipine is used to treat chest pain (angina) and other conditions caused by coronary artery disease.
Amlodipine is also used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack.
Amlodipine is for use in adults and children who are at least 6 years old.
Before taking amlodipine, 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 amlodipine.
If you are being treated for high blood pressure, keep using amlodipine 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.
Amlodipine is only part of a complete program of treatment that may also include diet, exercise, weight control, and other medications. Follow your diet, medication, and exercise routines very closely.
Tell your doctor about all other heart or blood pressure medications you are taking.
Your chest pain may become worse when you first start taking amlodipine or when your dose is increased. Call your doctor if your chest pain is severe or ongoing.
Before taking this medicine
You should not take amlodipine if you are allergic to it.
To make sure amlodipine is safe for you, tell your doctor if you have ever had:
Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether amlodipine will harm an unborn baby. However, having high blood pressure during pregnancy may cause complications such as diabetes or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of treating hypertension may outweigh any risks to the baby.
Amlodipine can pass into breast milk, but effects on the nursing baby are not known. Tell your doctor if you are breast-feeding.
Amlodipine is not approved for use by anyone younger than 6 years old.
