Two days later, I began to break out with hives and went to the emergency room. The doctor put me on Prednisone and continue to have them every day. My dermatologist had me go off Lipitor for six weeks and now I am back on Lipitor and now also on Zyrtec. Thinking this might have been caused by Pfizer COVID-19 Vaccine Bivalent Grey Cap Adult Dose. For two months I have no hives." She mentioned her doctor wants to know if any particular preservative in the vaccine is present which may have caused the hives. She wants to know if Pfizer was able to point out what caused people to have hives or react to the vaccine like this. Caller clarified she received the Pfizer booster in Sep2022 and she ended up with chronic hives for weeks and ended up going to a dermatologist, the doctors cannot figure out, they did some tests, they stopped Lipitor, and now she is back on Lipitor but she is fine, it must be the booster, asking if there are some preservatives in the booster that could have triggered the allergies.
