For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments. No concomitant medications were provided. No treatment medications were reported. The patient saw a dermatologist on 07Dec2021. He diagnosed it as pressure hives and dermographism. He expected it to be gone in a week to four weeks without explanation. She was taking Xyzal, which is the only thing that works. She had tried other antihistamines (Claritin, Allegra, Benadryl, and Zyrtec). It reduced the number of hives that pop up. After she took Benadryl, it made her loopy. It worked but she doesn't like to take it. Zyrtec worked, but it wears off sooner. This case was linked to MOD-2022-439146, MOD-2022-439197 (Patient Link).
