I was initially diagnosed with a rash & itching characterized as GD 2 years ago, however was inconsistent with other symptoms such as itching with no rash, and from head to feet. The itching was maddening, and nothing worked to sufficiently reduce the pain & itching sufficiently to sleep more than an hour at a time. The rash, where it did occur, seemed to morph into Eczema-type characteristics, and my Dermotologist suggested I try Dupixent. I can tell you this was a game changer, after 5 weeks of being on it, the rash and itching was 80-90% abated, and feel normal again. I’ve been on it for 3 months now with no side effects. My Derm told me there would be several other new biologics coming to market and hopefully might offer others the same type of miraculous results Dupixent gave me.
