What Antabuse Stands For

Key active ingredient: Disulfiram.

Antabuse is a prescription medicine used in the management of alcohol dependence. It works by inhibiting aldehyde dehydrogenase so that if alcohol is consumed a toxic metabolite called acetaldehyde accumulates. This produces unpleasant symptoms that act as a deterrent to drinking. Antabuse is most effective when combined with psychological support and regular medical follow up. Regard the section described here. Who should take advantage of this? for details about suitability.

Who should employ this?

Primary indication: treatment to support abstinence in people with alcohol use disorder who have stopped drinking and want a pharmacological aid to maintain abstinence.

Antabuse is usually recommended when the treatment goal is total abstinence and also the patient understands the need to avoid all sources of alcohol. It should be prescribed only as part of a structured plan that includes counselling, peer support or specialist addiction services. For legal and prescribing information in the UK, see United Kingdom Compliance and Access Details.
