How It Works

Beta-blockers interrupt the normal chemical signals transmitted by nerves that stimulate, and sometimes overstimulate, the pacing of the heart. They slow down the heartbeat and reduce blood pressure.

Why It Is Used

Beta-blockers are used for mitral valve prolapse to relieve symptoms of palpitations or chest pain that might happen with this condition. Beta-blockers do not improve the functioning of the mitral valve.

How Well It Works

Beta-blockers can relieve symptoms of palpitations or chest pain in people with mitral valve prolapse. 1

Side Effects

All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

Here are some important things to think about:

  • Usually the benefits of the medicine are more important than any minor side effects.
  • Side effects may go away after you take the medicine for a while.
  • If side effects still bother you and you wonder if you should keep taking the medicine, call your doctor. He or she may be able to lower your dose or change your medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.

Call 911 or other emergency services right away if you have:

  • Trouble breathing.
  • Swelling of your face, lips, tongue, or throat.
  • Fainting or severe dizziness.

Call your doctor right away if you have:

  • Hives.
  • Very slow heart rate (less than 50 beats per minute).
  • Swelling in legs or feet.
  • Shortness of breath or wheezing, especially if you have asthma.
  • Cold hands and feet.

Common side effects of this medicine include:

  • Dizziness or lightheadedness.
  • Feeling tired.
  • Trouble sleeping.

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

What To Think About

Check your pulse. Your doctor may ask you to take your pulse regularly to make sure your heart rate is not too slow. To learn how to take your pulse, see the topic Taking a Pulse (Heart Rate) .

Diabetes. If you have diabetes, beta-blockers may cause higher blood sugar levels. Watch closely for symptoms of low blood sugar, because beta-blockers can hide your symptoms.

Grapefruit juice. Grapefruit juice may affect how beta-blockers work. Ask your doctor if you need to make any changes to avoid problems. For more information, see Grapefruit Juice and Medicine.

Cold weather. Beta-blockers may make you more sensitive to cold weather. Dress warmly and if necessary, limit your time in cold weather.

Sun exposure. Beta-blockers may make you more sensitive to sunlight. You might get sunburnt easily or get a rash. To prevent problems, try wearing sunblock, long-sleeved shirts, and hats.

Allergic reactions. If you have food, medicine, or insect-sting allergies, beta-blockers may cause allergic reactions to be worse and harder to treat. If you have a severe allergic reaction, tell your doctor that you are taking a beta-blocker.

Taking medicine

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.

There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.

Advice for women

If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.

Checkups

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
