Antabus is used alone or with other treatments for people who are dependent on alcohol.
For starting and ongoing treatment, take 1/2 to 1 tablet (100–200 mg) daily, or 2 to 4 tablets (400-800 mg) twice a week (e.g., Tuesdays and Fridays).
Dissolve the tablet in half a glass of water (about 100 ml) just before taking it, stir, and drink immediately. The best time to take it is in the morning, but if it makes you tired, you can take it in the evening.
Do not exceed 1 tablet (200 mg) daily, or 4 tablets (800 mg) on the two days a week when it is taken.
