What is Amlodipine?
Amlodipine belongs to a class of medications called calcium channel blockers. It lowers blood pressure by relaxing the blood vessels so the heart does not have to pump as hard.
Amlodipine is used to treat certain types of angina (chest pain) and other conditions caused by coronary artery disease (narrowing of the blood vessels that supply blood to the heart).
Amlodipine controls chest pain by increasing the supply of blood to the heart. If taken regularly, this medicine controls chest pain, but it does not stop chest pain once it starts. Your doctor may prescribe a different medication to take when you have chest pain.
Amlodipine is also used alone or in combination with other medicines to treat high blood pressure (hypertension) in adults and children at least 6 years old. Lowering blood pressure may lower your risk of a stroke or heart attack.
Warnings
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.

If you have high blood pressure, keep using amlodipine even if you feel well. High blood pressure often has no symptoms.

Before Taking
You should not take amlodipine if you are allergic to it.
To make sure this medicine is safe for you, tell your doctor if you have ever had:
-
severe narrowing of a certain valve in your heart (aortic stenosis), or other heart problems;
-
coronary artery disease (clogged arteries); or
-
liver disease.
It is not known if amlodipine will harm an unborn baby. However, having high blood pressure during pregnancy may cause complications or medical problems in both mother and baby. The benefit of treating hypertension may outweigh any risks to the baby.
Tell your doctor if you are breastfeeding.
What happens if I miss a dose?
Take the medicine as soon as you can, but skip the missed dose if you are more than 12 hours late for the dose. Do not take two doses at one time.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store the tablets at room temperature and away from excess heat and moisture (not in the bathroom). Store the suspension in the refrigerator and avoid freezing; protect it from light.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
