Good evening @leen36. I chose the same Pfizer path as you did. So far, so good. I also have Neuropathic itch and atopic dermatitis. So itch is my greatest irritation. There is a new product available that helps me and it is called Dermeleve. You can order it online at dermeleve.com. My dermatologist brought it back from a conference she attended. It is my go-to for immediate response. Once applied, it takes about 15 minutes to work and lasts about 6 hours. So it is not the be-all, end-all, and yet it takes care of the "itch" for enough time for you to recover.

Would you please tell me what your outlook is for dermatographia at this point?
May you be safe, free and protected from inner and outer harm.
Chris
