Paul, no one really knows if your very short courses of antibiotic are wise or unwise. If pouchitis were a conventional infection then very short courses would tend to lead to bacterial resistance, making the antibiotic less effective in the future. But pouchitis isn’t a conventional infection, so it’s possible that the reduced side effects (during a very short course) are worth the trade-off. You are making it up though - there’s no data to support your approach, whereas there’s a fair amount of data supporting a 10-14-day course.
