What is insect sting allergy?
Most children have a normal, local reaction to a sting — pain, redness and swelling right at the site. A minority develop an allergic reaction to venom proteins, which can range from a larger local swelling to a systemic reaction affecting skin, breathing or circulation across the whole body.
Normal reaction vs allergic reaction
- Normal: pain, redness, mild swelling confined to the sting site, settling over a few days
- Large local reaction: swelling extending well beyond the sting site, lasting several days
- Systemic allergic reaction: hives, swelling away from the sting site, breathing difficulty, dizziness — this can progress to anaphylaxis and needs emergency treatment
First-aid for a sting
- Remove a visible stinger by scraping it out (avoid squeezing, which can release more venom)
- Clean the area and apply a cold compress for local swelling
- Give an antihistamine for itching/mild swelling as advised by your doctor
- Watch closely for any spreading symptoms over the following hour
When it's an emergency
Difficulty breathing, throat tightness, widespread hives, dizziness or fainting after a sting are signs of a systemic allergic reaction — use an adrenaline auto-injector if one has been prescribed and seek emergency care immediately.
Testing & treatment
Children who have had a systemic reaction to a sting should be evaluated with a detailed history and, where appropriate, testing to confirm venom allergy, since venom immunotherapy can be highly effective at preventing future severe reactions in confirmed cases.
Talk to Dr. Narwani: If your child's symptoms are affecting sleep, school, play or growth, or you suspect a specific trigger, book a consultation for proper allergy work-up rather than guessing at home remedies.
