Thank you @lol for your helpful feedback! I have previously considered taking Xolair per my dermatologist’s recommendation as a last resort. Because of XOLAIR’s possible serious side effects, I am holding off on it and trying to obtain first-hand information on the experiences of people who have completed their Xolair regimen. I am currently on my 10th month journey of Dermatographia. My severe rashes first appeared in April, 2022 twelve days after receiving my second Moderna booster shot. My doctor prescribed Allegra 180 mgs. twice a day (AM and PM), Montelukast once a day, and one Zyrtec before bedtime on an as needed basis. After six months, I was able to comfortably decrease the treatment from 1 Allegra daily to 1 Allegra every other day which lasted for two months; then 1 Allegra every other three days for one month. I feel I am now ready to space my Allegra intake of 1 tablet out every other four days (my 10th enduring month). The over-the-counter CUREL Anti-Itch lotion is my go-to remedy for sporadic brief itching. I am hoping that this dermatographia would soon clear itself out of my system and skip Xolair treatment altogether. I wonder where Moderna and Pfizer stand on this issue?
