Penicillin Allergy in Children: Myths, Diagnosis, Delabelling, and Safe Antibiotic Choices

Penicillin allergy is one of the most commonly reported drug allergies in children — but many children labelled as “penicillin allergic” are not truly allergic. In this episode, we explore why penicillin allergy labels matter, how they can affect antibiotic choices, and why accurate assessment is so important for safer, better care.We discuss the difference between true allergic reactions and common childhood rashes, the key features clinicians look for in the history, and when referral or allergy testing may be needed. The episode also looks at penicillin allergy “delabelling” — the process of safely removing an inaccurate allergy label — and how this can help children access first-line antibiotics, reduce unnecessary use of broad-spectrum alternatives, and support antimicrobial stewardship.This episode is ideal for parents, healthcare professionals, medical trainees, nurses, pharmacists, and anyone interested in paediatric allergy and safe antibiotic prescribing.Listen now to understand penicillin allergy in children, how it is diagnosed, and why many allergy labels deserve a second look.Sources:Barbaud, A., Garvey, L.H., Torres, M., Laguna, J.J., Arcolaci, A., Bonadonna, P., Hofmeier, K.S., Chiriac, A.M., Cernadas, J., Caubet, J.C. and Brockow, K.
