What is Amlodipine?

Amlodipine is part of a class of medicines known as calcium channel blockers. It lowers blood pressure by relaxing blood vessels so that the heart doesn't have to pump as much.

Amlodipine is utilized to treat certain kinds of angina (chest pain) and other disorders due to coronary arterial diseases (narrowing of blood vessels that carry oxygen to the heart).

Amlodipine reduces chest pain by enhancing the flow of blood into the heart. If it is taken on a regular basis, the medicine can help reduce chest pain, but it doesn't stop the pain after it begins. Your doctor might prescribe an alternative medication if you experience chest pain.

Amlodipine can be taken by itself or in conjunction with other medications in order to manage hypertension in adults and children who are at least six years old. The reduction in blood pressure could reduce your chance of suffering a stroke or heart attack.


Before you take amlodipine, inform your physician if you have congestive liver disease or heart failure.

Drinking alcohol may further lower your blood pressure and increase the adverse effects of amlodipine.

If you're receiving treatment to treat high blood pressure, you should continue taking amlodipine, even if you are feeling well. The condition is often accompanied by no signs. It is possible that you will need blood pressure medications throughout your life.

Amlodipine is just a small part of a comprehensive treatment that could include diet and exercise, weight loss, and various other medications. Be sure to follow your diet, medications, and exercise routines with the utmost care.

Discuss with your doctor all other blood pressure or heart medications you're taking.

Your chest pain could worsen when you first take amlodipine or increase your dosage. Contact your physician if the chest pain you experience is intense or continues to persist.

Before you Take this Drug

It is not recommended to take amlodipine if you are allergic to it.

To ensure this medication is appropriate for you, tell your physician if you have any of the following:

  • The severe narrowing of a particular valve inside the coronary artery (aortic stenosis) or other heart-related problems.
  • Coronary arterial condition (clogged arteries) or
  • Liver disease.

It is not known if amlodipine can harm an unborn baby. But elevated blood pressure during pregnancy can result in medical issues or complications for both the mother and the baby. The benefits of treating hypertension can outweigh the risks to the infant.

How to Take Amlodipine?

Amlodipine should be taken exactly as directed by your physician. Follow the directions on the prescription label, and make sure you read all the instructions or medication guides. Your doctor may alter your dosage.

Amlodipine is typically taken once a day.

Use the medicine every day, either with or without eating.

Shake to mix the oral suspension (liquid). Use the measuring device supplied (not a spoon from the kitchen).

If you are suffering from hypertension, continue taking amlodipine, even if you feel good. The presence of high blood pressure is often accompanied by no signs.

Don't alter the doses or discontinue taking any medication without consulting your physician.

Your treatment could include exercise, diet control, and blood tests.
