I would love to try Dupixent as nothing else is working very well. The issue is that it is not FDA approved for Grover's, but is approved for Atopic Dermatitis (Eczema) and my dermatologist won't put me in for it because she would be lying. It's unaffordable unless approved so if your Dr can get you approved I would definitely try it. I may start looking for a dermatologist that can do that for me. Good luck!
