Beta-blockers are a class of drugs used
to control symptoms of
heart failure that are made worse by certain hormones
catecholamines. The body releases these hormones as
part of its
response to heart failure. For this and other reasons,
beta-blockers have been shown to be effective for treating most people who have
Beta-blockers have a variety of effects throughout
the body. They are used to treat heart disease that causes chest pain, high
heart attacks, and
cardiomyopathy and irregular, rapid heartbeats
(arrhythmia). Beta-blockers are also used to prevent migraine headaches, treat
tremors, and control anxiety.
Bisoprolol, carvedilol, and metoprolol are some of the
beta-blockers that have been tested for use in the treatment of heart
Beta-blockers can slow the
systolic forms of heart failure.
Beta-blockers may be used to treat left ventricular systolic dysfunction
in people who are stable and have no symptoms or only mild to moderate heart
failure symptoms. Beta-blockers may be used together with other medicines
that are usually used to treat heart failure, such as angiotensin-converting
enzyme (ACE) inhibitors or diuretics.
Beta-blockers may be used to treat diastolic heart failure too. With diastolic heart failure, the heart does not have enough time to relax and
fill with blood before pumping it out to the rest of your body. Beta-blockers help treat diastolic heart failure, because they slow the heart rate and allow more time for your heart to fill with blood. This allows
the left ventricle to fill more completely and increases the volume of blood
that the heart pumps with each heartbeat (ejection fraction). Then, your heart can pump more blood with each heartbeat.
Certain beta-blockers have been
Beta-blockers are one of four medicines recommended for use
in most people who have systolic heart failure. Others include diuretics, ACE
inhibitors, and sometimes digoxin.
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.

Common side effects of this medicine include:
See Drug Reference for a full list of side effects.
(Drug Reference is not available in all systems.)
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 Medicines.
Cold weather. Beta-blockers may make you more sensitive to cold weather. Dress warmly and if needed, 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 sun block, 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.
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.
For tips on taking medicine for heart failure, see:
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.
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.
