By the book, 10 days: The 'antabuse' (or disulfiram) effects of Metronidazole may last many days, in some cases as many as 10 days after a usual 7-10 day course of flagyl, and the potential to get nausea, vomiting, flushing, severe headache and even fainting from an antabuse-reaction may be present for that long.
