Acebutolol is prescribed to treat a number of conditions. If you are unsure why you are taking it, speak with your doctor.
Treatment with acebutolol is usually long-term. Continue to take the tablets/capsules regularly - do not stop without speaking with your doctor first, as this can cause problems.
The most commonly experienced side-effects are tiredness and stomach upset.
De un vistazo
Acebutolol is a beta-blocker medicine used for high blood pressure, angina, and irregular heartbeats.
It works by slowing your heart activity, causing it to beat more slowly and with less force.
Take acebutolol exactly as prescribed, often once, twice, or three times a day.
Do not stop taking acebutolol suddenly, as your doctor may need to reduce your dose gradually.
Common side-effects include feeling tired, dizzy, sick, or having a headache.
About acebutolol
Tipo de medicamento | Un medicamento bloqueador de los receptores beta-adrenérgicos (a menudo llamado betabloqueante) |
Usado para | High blood pressure; angina; irregular heartbeats |
También llamado | Sectral® |
Disponible como | Comprimidos |
Acebutolol belongs to the group of medicines known as betabloqueantes. It works on the heart and blood vessels.
Acebutolol slows down the activity of your heart by stopping messages sent by some nerves to your heart. It does this by blocking tiny areas (called beta-adrenergic receptors) where the messages are received by your heart. As a result, your heart beats more slowly and with less force. This allows the pressure of blood within your blood vessels to be reduced if you have presión arterial alta (hipertensión), and helps to prevent abnormally fast and uneven heartbeats if you have a heart rhythm disorder (arrhythmia). Because your heart is using less energy, it helps to reduce chest pain if you have angina.
Before taking acebutolol
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking acebutolol it is important that your doctor knows:
Si estás embarazada, intentando tener un bebé o amamantando.
Si tienes algún problema con el funcionamiento de tus riñones.
Si tienes asma u otro trastorno respiratorio.
Si tienes diabetes (diabetes mellitus).
If you have been told you have a slow heartbeat or a slow and irregular heartbeat (heart block).
If you have been told you have chest pain caused by spasms of your heart's blood vessels, a condition called Prinzmetal's angina.
If you have low blood pressure, heart failure, or poor circulation.
Si tienes un problema de piel llamado psoriasis.
Si tienes una condición que causa debilidad muscular, llamada miastenia gravis.
Si tienes un tumor en la glándula suprarrenal, llamado feocromocitoma.
Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.
Si alguna vez ha tenido una reacción alérgica a un medicamento, o si ha tenido alguna otra reacción alérgica grave.
How to take acebutolol
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about acebutolol and will provide you with a full list of the side-effects which you may experience from taking it.
Your doctor will tell you what dose is right for you, and this information will be printed on the label of the pack to remind you. Take acebutolol exactly as your doctor tells you to. You may be asked to take a dose once, twice or three times a day.
Swallow the tablet with a drink of water. Acebutolol will work the same whether you take your doses before or after food; however, taking your doses after a meal will help to reduce the risk of stomach upset. Try to take your doses of acebutolol at the same times each day. This will help you to remember to take them regularly.
Acebutolol is available in several different strengths. When starting your treatment your doctor may give you a small dose at first and then gradually increase it. Each time you collect a fresh supply, it's a good idea to check the strength on the packet to make sure they are what you are expecting.
Si olvida tomar una dosis, tómela tan pronto como lo recuerde. Si cuando lo recuerda, ya es casi la hora de su próxima dosis, entonces tome su próxima dosis cuando corresponda, pero omita la dosis olvidada. No tome dos dosis juntas para compensar una dosis olvidada.
Obteniendo el máximo de tu tratamiento
Intenta mantener tus citas regulares con tu médico. Esto es para que tu médico pueda verificar tu progreso.
Treatment with acebutolol can often be long-term. Continue to take the tablets/capsules unless your doctor tells you to stop. Stopping treatment suddenly can cause problems in some people, so your doctor may want you to reduce your dose gradually if this becomes necessary.
If you are due to have an operation or dental treatment, it is important to tell the person carrying out the treatment that you are taking a beta-blocker. This is because some anaesthetics may increase the risk of unwanted effects.
If you drink alcohol, ask your doctor for advice. Alcohol will add to the blood pressure-lowering effect of acebutolol and so may not be advisable for you.
If you have diabetes, acebutolol can mask the symptoms of low blood sugar. Your doctor will advise you about this.
If you buy any medicines, check with a pharmacist that they are suitable for you to take. Some medicines (including some painkillers, cold and flu remedies) may not be.
Your doctor may give you dietary and lifestyle advice about eating a healthy diet, not smoking, and taking regular exercise. If so, it is important that you follow the advice you are given.

Sentirse mal (náuseas) o estar enfermo (vómitos), diarrea | Stick to simple meals - avoid rich and spicy foods. If you are not already doing so, try taking your doses after meals |

Cold hands or feet, feeling short of breath, disturbed sleep, mood changes, nightmares, skin rash | Si alguno de estos se vuelve problemático, hable con su médico |
