Acebutolol - a beta-blocker

About acebutolol

Acebutolol belongs to the group of medicines known as beta-blockers. 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 high blood pressure (hypertension), 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.

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:

• Om du är gravid, försöker bli gravid eller ammar.

• Om du har några problem med hur dina njurar fungerar.

• If you have asthma or any other breathing disorder.

• If you have 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.

• If you have a skin problem called psoriasis.

• Om du har ett tillstånd som orsakar muskelsvaghet, kallat myasthenia gravis.

• If you have a tumour on your adrenal gland, called phaeochromocytoma.

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• If you have ever had an allergic reaction to a medicine, or if you have ever had any other serious allergic reaction.

• 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.

• If you forget to take a dose, take it as soon as you remember. If when you remember, it is nearly time for your next dose then take your next dose when it is due but leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

• Försök att hålla dina regelbundna möten med din läkare. Detta är så att din läkare kan följa upp din utveckling.

• 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.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with acebutolol. You will find a full list in the manufacturer's information leaflet supplied with your tablets/capsules. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to acebutolol, speak with your doctor or pharmacist for further advice.

• Förvara alla läkemedel utom räckhåll och synhåll för barn.

• Förvara på en sval, torr plats, borta från direkt värme och ljus.
