<<Disclaimer: Verify this information before applying it to your situation.>> Cindy, I have sufferred DH for 35 years. I have been on 4 dapsone a day all this time. I do know dapsone is safe. One phamacutical company told me that all generic drugs are gluten free. I always call before taking a new drug. On the internet you can pull up large chains like Eckerd's and search for gluten free drugs. The celiac assoc puts out a book with gluten free drugs. The quickest way is to call the pharmacutical company or search for them on the internet. They are always most helpful to me. Mary
