Just curious, if your child reacted to an antibiotic with crazy hives, what was your experience with how long it took to resolve and did anything really help?

I knew she had gotten a few small hives earlier in the meds (for UTI) but didn’t think the dr would change anything based on that - well then of course she hit her threshold and the hives went insane. We stopped the med Friday but the hives are as bad or worse now. Constantly moving of course but everywhere. Dr suggested Benadryl the first day followed by Zyrtec and I do think it’s helped the itching some but wondering how long this may last? She just tested out of needing epipens for food allergies but clearly her immune system is still looking for trouble …

Also would you be totally freaked out if a kid covered in hives came to school?? (Her teacher knows.)
