Insect sting & medication allergies in children
A dramatic reaction to a bee sting, or a rash during a course of antibiotics, leaves families with a label — “allergic” — and a lot of worry. Sometimes that label is right and needs a proper plan. Surprisingly often, it’s wrong and can be safely removed.
Both outcomes are valuable. A child with a genuine sting allergy needs an action plan; a child wrongly labelled penicillin-allergic deserves to have first-line antibiotics back for the rest of their life.

Why Dr O’Reilly
Specialist care, not a fifteen-minute appointment
Dr Elize O’Reilly (BMedSci, MBBS(Hons), MHL, FRACP) is a paediatric immunologist and allergist and a general paediatrician — the specialist in the room at every appointment. Care at Little Reactions is unhurried, evidence-based and explained in plain language, and your GP stays in the loop with letters you can both read.
- FRACP specialist
- Paediatric-only practice
- Same-day test results
How we investigate
These are areas where careful specialist assessment changes the label — in both directions:
- A precise history of the reaction: timing, appearance, treatment needed
- Skin and blood testing for sting allergy where the reaction warrants it
- Assessment of drug-allergy labels, with referral for supervised challenge testing where appropriate
How we manage it
Clear, proportionate plans — neither dismissive nor alarmist:
- ASCIA action plans and adrenaline injector training for confirmed sting allergy
- Practical sting-avoidance advice for Queensland outdoor life
- De-labelling documentation when a drug allergy is excluded, shared with your GP and pharmacist
- Referral for venom immunotherapy where it’s indicated
