Disulfiram tablets

About disulfiram

Disulfiram is used alongside other treatments and counselling for alcohol dependency. It is only suitable for people who have been through detoxification ('detox') and have stopped drinking alcohol. It acts as a deterrent to drinking further alcohol.

Disulfiram works by interfering with the way your body breaks down alcohol. Usually when you drink alcohol, your body breaks the alcohol down into a substance called acetaldehyde. This is then broken down further so that it can be removed from your body. Disulfiram blocks the enzyme which breaks down the acetaldehyde. This leads to high levels of acetaldehyde in your blood and causes an unpleasant effect.

If you drink even a small amount of alcohol with disulfiram, it will produce an extremely unpleasant reaction. It will give you a throbbing headache, a flushed face, and the sensation of having a 'thumping heart' (palpitations), and it will make you feel very sick. This reaction starts within about 10 minutes of drinking alcohol and can last for several hours. Knowing this will happen will help stop you from drinking alcohol. Because drinking larger amounts of alcohol can cause potentially dangerous reactions, disulfiram is only prescribed by specialists to people who are determined to stay off alcohol.

Before taking disulfiram

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 disulfiram it is important that your doctor knows:

• Wenn Sie schwanger sind, ein Kind erwarten oder stillen.

• If you have a problem with your heart, or if you have high blood pressure.

• If you have had a mental health problem called psychosis, or if you have ever had a personality disorder.

• If you have had a stroke or a transient ischaemic attack (TIA).

• Wenn Sie Probleme mit der Funktionsweise Ihrer Leber oder Ihrer Nieren haben.

• Wenn Sie Diabetes haben.

• Wenn Sie Epilepsie haben.

• If you have problems with your breathing.

• Wenn Sie an einer seltenen Erbkrankheit namens Porphyrie leiden.

• Wenn Sie andere Arzneimittel einnehmen. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

How to take disulfiram

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The manufacturer's leaflet will give you more information about disulfiram and a full list of the side-effects which you may experience from taking it.

• It is important that you have not drunk any alcohol for at least 24 hours before you take your first dose of disulfiram.

• Take disulfiram exactly as your doctor tells you to. You may be asked to take several tablets a day during the first few days of treatment, but after this your dose will be reduced. As a guide, the usual recommended daily dose is one 200 mg tablet, although your dose may be different to this.

• If you forget to take a dose, take it as soon as you remember, if it is still within 12 hours of when the dose was due. If you do not remember until more than 12 hours later, skip the missed dose. Do not take two doses together to make up for a forgotten dose.

Das Beste aus Ihrer Behandlung herausholen

• Disulfiram will be started in hospital or in a clinic, and then it is supervised by a specialist. Keep your regular appointments with your doctor and counsellor. This is so your progress can be checked on a regular basis.

• Make sure your family and friends know how important it is that you do not drink any alcohol, so that they can be a support to you. Even low alcohol, 'non-alcohol' or 'alcohol-free' beers and wines may cause a reaction.

• Even relatively small amounts of alcohol with disulfiram can produce severe reactions. Many liquid medicines, toiletries and mouthwashes contain sufficient alcohol to produce an effect. Always read the contents on the label and avoid any product which contains alcohol. If you buy any medicines, check with a pharmacist that they are safe for you to take.

Can disulfiram cause problems?

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 disulfiram. 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.

If you experience any other symptoms which you think may be due to this medicine, discuss them with your doctor or pharmacist.
