Common use
Antabuse is used for treating alcoholism. Antabuse is an alcohol-abuse deterrent. It works by blocking the breakdown of alcohol, causing unpleasant side effects (eg, vomiting, upset stomach) when even a small amount of alcohol is consumed.

Antabuse may be taken with or without food.
Antabuse may be swallowed whole, chewed, or crushed and mixed with food.
Do not take the first dose of Antabuse for at least 12 hours after drinking alcohol.
If you miss a dose of Antabuse, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Antabuse.

Important safety information:
Antabuse may cause drowsiness. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to Antabuse. Using Antabuse alone, with certain other medicines, or with alcohol may lessen your ability to drive or perform other potentially dangerous tasks.
Avoid all alcohol including alcohol found in sauces, vinegar, mouthwash, liquid medicines, lotions, after shave, or backrub products. A reaction to alcohol may cause flushing, nausea, thirst, abdominal pain, chest pain, dizziness, vomiting, fast breathing, fast heartbeat, fainting, difficulty breathing, or confusion. Use caution when using topical products containing alcohol, such as cologne or perfume. Before using alcohol-containing products on the skin, test the product by applying some to a small area of the skin. If no redness, itching, headache, or nausea occurs after 1 or 2 hours, you should be able to use the product. You may have a reaction if you drink alcohol or use a product that contains alcohol for 2 weeks after your last dose of Antabuse.
Notify your doctor immediately if you experience yellowing of the skin or eyes, dark urine, weakness, tiredness, loss of appetite, or nausea and vomiting. These may be signs of a liver problem.
Before you have any medical or dental treatments, emergency care, or surgery, tell the doctor or dentist that you are using Antabuse.
Lab tests, including liver function tests and complete blood cell counts, may be performed to monitor your progress or to check for side effects. Be sure to keep all doctor and lab appointments.
Pregnancy and breast-feeding: If you become pregnant, discuss with your doctor the benefits and risks of using Antabuse during pregnancy. It is unknown if Antabuse is excreted in breast milk. Do not breastfeed while taking Antabuse.
