Antabuse is a prescription drug used to help individuals suffering from Alcohol Use Disorder (AUD) to reduce cravings and stop drinking. It belongs to a class of drugs called Psychiatry Agents. Antabuse works by producing an unpleasant reaction when combined with alcohol, thereby discouraging people from drinking alcohol.
Antabuse, also known as Disulfiram, is a medicine used to treat alcohol addiction. When alcohol enters the body, it is broken down into acetaldehyde by alcohol dehydrogenase, and then into acetic acid by aldehyde dehydrogenase.
Disulfiram works by blocking the conversion of acetaldehyde to acetic acid, resulting in an upsurge of acetaldehyde. This upsurge is toxic and causes the individual to become ill, leading to strong feelings of aversion to alcohol.
Uses and Dosage
Antabuse (Disulfiram) comes in tablets to be taken orally once a day. It should be taken by mouth with or without food, usually once daily in the morning or as directed by your doctor. Follow the directions on the prescription label carefully and ask your doctor or pharmacist to explain any part that is not understood. Take the medication exactly as prescribed and do not take more or less of it than is prescribed by the doctor.
Disulfiram should be taken regularly to ensure the metabolic cycle continues, reducing the desire to drink alcohol. It is available in 250 mg or 500 mg tablets, with the maximum recommended daily dosage being 500 mg.
