I’m so sorry to read of your medical history, as I am not a physician I can’t make any recommendations, just tell you about my own course with Bullous Pemphigoid (BP). First off, I had a biopsy to confirm BP, I’m told this is required. Initial course of prednisone 10mg/day that stopped horrible itching and cleared skin. Dupixent injectable was recently approved for use on BP, can be hard to get insurance approved but did after one appeal. I’ve been on for six weeks and now weaning off steroids. I’m fortunate that this all seems to be working. Dermatologist says that age is the primary risk factor. I’m 75. Hope this helps.
