<<Disclaimer: Verify this information before applying it to your situation.>> Is anyone aware of either clinical research or personal experience re: the lag time between ingestion of gluten and skin breakout in persons with DH? My own experience suggests that it is quite long, perhaps as long as several weeks, but I haven't tested this systematically. My dermatologist isn't aware of such work either. I am planning to go gluten-free but am trying to figure out when it's safe to stop taking dapsone before all the gluten consequences are out of my system. Any experience with this you could share would be very helpful. Thanks, Hal Grotevant St. Paul, MN [log in to unmask]
