Carvedilol tablets - a beta-blocker

About carvedilol

Carvedilol is a type of beta-blocker that is used to treat high blood pressure, chest pain (angina), and heart failure.

It is a medicine which works on the heart and blood vessels. It does this by blocking tiny areas (called beta-adrenergic receptors) where messages sent by some nerves are received by your heart and blood vessels. As a result, your heart beats more slowly and with less force. The pressure of blood within your blood vessels is reduced and it is easier for your heart to pump blood around your body.

These actions are of benefit if you have high blood pressure (hypertension), or if you have heart failure which is a condition where your heart is not working as well as it should. Because your heart is using less energy, it also helps to reduce chest pain if you have angina.

The most common side effects of carvedilol are:

• Feeling dizzy or lightheaded.

• Feeling sleepy or tired.

• Headache.

You may also experience other common side effects such as:

• Känna sig illamående (illamående).

• Kräkningar.

• Indigestion.

• Diarré.

• Magont.

• Cold fingers and toes.

• Infections.

• Feeling depressed.

• Weight gain.

• Swollen feet and ankles.

• Slow heartbeat.

• Eyesight problems.

• General aches and pains.

You will find a full list in the manufacturer's information leaflet supplied with your medicine. 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.

Om du upplever några andra symtom som du tror kan bero på tabletterna, tala med din läkare eller apotekare för vidare råd.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking carvedilol it is important that your doctor knows:

• Om du är gravid eller ammar.

• If you have asthma or any other breathing disorder.

• Om du har några problem med hur din lever fungerar, eller om du har några problem med hur dina njurar fungerar.

• If you have low blood pressure or poor circulation.

• If you have diabetes.

• If you have a skin problem called psoriasis.

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

• If you have been told you have a slow heartbeat or heart block (a slow and irregular heartbeat).

• If you have been told you have chest pain caused by spasms of your heart's blood vessels, called Prinzmetal's angina.

• 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.

• Read the manufacturer's printed information leaflet from inside the pack. It will give you more information about carvedilol and will provide you with a full list of the side effects which you may experience from taking it.

• Take the tablets exactly as your doctor tells you to. Depending on the reason you are taking carvedilol, you will be asked to take either one or two doses a day.

  • People with high blood pressure are usually asked to take one dose a day, whilst people with angina or heart failure will be asked to take two doses a day.

  • Your doctor will tell you which dose is right for you, and the directions for taking the tablets will also be printed on the label of the pack to remind you about what the doctor said.

• Carvedilol tablets are available in several different strengths. When starting your treatment your doctor may give you a low-strength tablet and then gradually increase the strength of the tablets over a few days or weeks.

  • Each time you collect a fresh supply of tablets it is a good idea to check to make sure you receive the strength you are expecting. If you have any questions, please ask your pharmacist to advise you.

• You can take the tablets either with or without food, but try to take your doses at the same time of day each day as this will help you to remember to take carvedilol regularly. The tablets are best swallowed with a drink of water.

• If you forget to take a dose, take it as soon as you remember (unless it is nearly time for your next dose, in which case leave out the missed dose and take the next dose as normal). 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.

• The tablets can reduce the amount of tears your eyes make. If you wear contact lenses and this causes your eyes to feel drier than usual, speak with your doctor or optician for advice.

• If you drink alcohol, ask your doctor for advice about taking carvedilol and alcohol. Alcohol will add to the blood pressure-lowering effect of carvedilol which will make you feel dizzy and so may not be recommended for you.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take with carvedilol. Some medicines may not be (including some anti-inflammatory painkillers, and cold or flu remedies).

• 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 particularly important if you are likely to be given an anaesthetic.

• 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.

• If you have diabetes, carvedilol can hide the symptoms of low blood sugar. Your doctor will advise you about this.

• Treatment with carvedilol is usually long-term. Continue to take the tablets 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.

• Förvara alla läkemedel utom räckhåll och synhåll för barn.

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