<<Disclaimer: Verify this information before applying it to your situation.>> I just thought I would put my 2 cents in on this, but I thought I had read somewhere that all dapsone does is mask the symptoms and suppress them, not eliminate them, so it would follow that for those taking it it is merely covering up the DH, not eliminating the deposits. Logically speaking, then, if those deposits can't dissapate on their own (how do they do that anyway?) they are going to continue to be a problem. Maybe the reason that it is possible to taper off is that the body is able to get rid of the dh slowly, but say more slowly than for those off dapsone I don't know.... Just for the record, I have never used dapsone or anything topical for DH, so I can't give an informed opinion on taking it, and was told that there was NOTHING topical that could help.
