I’ve been researching this myself. My doctor got it approved for me. I was only hesitant that it was immunosuppressive but it looks like it does not suppress your whole immune system. Only IL4 and IL13 and doesn’t show any increase in malignancies. Not sleeping for 10 months due to itching and no cream, pill, or anything else I try has helped, I am going to give Dupixent a try. I’ve seen on other sites people with Grover’s said it is a game changer for them. Have you had any side effects? Especially eyes? That seemed to be most reported side effect.
