Rash after new medicine

Mia • M O M M Y 💕

Okay, my son has bronchitis (I’ve posted multiple times) they gave him a steroid, antibiotic and a breathing treatment twice a day for all of it. Today, he has this rash. Is this normal? I’m waiting for the nurse to call me back! His temp is only 99.5. Nothing has changed in his life but the medication and him being sick.

UPDATE- he is allergic to penicillin! So they called in a new medication! Poor baby!
