Antabuse (generic name: disulfiram) is generally prescribed for the treatment of alcoholism.

It works by blocking the metabolism of acetaldehyde, which is a product of alcohol when broken down by the body. The oral tablets often take no more than 15 minutes to work and they continue to work as long as alcohol is in one's system. Typically, patients aren't given Antabuse until 12 hours have passed since they had any alcohol.

When patients are pretreated with Antabuse, the "disulfiram reaction" often kicks in. This unpleasant reaction can manifest in several ways, including:

  • Nausea and/or vomiting
  • Flushing
  • Head and neck throbbing
  • Headache
  • Sweats
  • Severe thirst
  • Chest pain and/or palpitations
  • Confusion
  • Tachycardia
