I am 83 and have MMP in my mouth, eyes and nose. I had 2 gum biopsies to determine the diagnosis. I was first put on Azathioprine. I am terribly allergic to yellow dye and yellow compound. I have not be able to take the other meds usually prescribed. I was put on Dapsone. As I got up to 50 mg I had symptoms of A Fib. Even at low doses I have problems. I am currently on Dapsone 25 mg every other day. I also Tacrolimus mouth rinse 2 x a day. I am fortunate to have a non aggressive form of MMP. It is a very scary condition. I see the top dermatologist on pemphigoid at the university. I see an ENT a couple times a year. I also see 3 Opthalmologists as I have bands in my eyes. The very best of luck.
