Hi there, I have been on Antabuse for the past 2 weeks at a dose of 200mg once daily. I stopped taking antabuse on Monday morning. Is it safe to drink on Friday night? How can I 'test' if the antabuse is safely all out my system? If it is not what will happen when I consume alcohol, and in what amount before I notice symptoms of the antabuse perhaps still in my system? If I have no reaction does it mean I am safe to drink? Would a reaction occur in say 20 minutes of a few mouthfuls of low alcohol beer say? Thanks in advance.
