<<Disclaimer: Verify this information before applying it to your situation.>> Listmates, A few months ago I was diagnosed with DH through a skin biopsy. Because of a change in my health care insurance, I had the opportunity to change dermatologists, one who was closer to my home. Neither dermatologist prescribed dapsone. The first prescribed sulfapyridine; the second Azulfidine (generic name: sulfasalazine). Both physicians told me that the reason that they had not prescribed dapsone was because of possible side effects. I was wondering if anyone else had used these drugs and how effective they were. Since I've been gluten free for about 3 months, I really don't know how effective the drugs are. I still have some redness and scaring but no blisters. I've also read on the list that those with DH have a very diverse period after the ingestion of gluten and the onset of the DH symptoms. What I would like to know is how long the dermatological symptoms persist after one returns to gf diet. Thanks.. I'll summarize.. Jim Lockwood Webster, TX
