Management of Wasp Sting

Initial Assessment and Treatment

Most insect stings cause mild local reactions that are self-limiting and require no specific treatment beyond symptomatic care 1
For local reactions from wasp stings, treatment should focus on applying cold compresses to reduce local pain and swelling, as recommended by the American Academy of Allergy, Asthma, and Immunology 1, 3
Oral antihistamines can be used to reduce itching and pain associated with the sting, with a strength of evidence based on clinical guidelines from the American Academy of Allergy, Asthma, and Immunology 1, 3
Oral analgesics may be considered for pain management, according to the American Academy of Pediatrics 1

The American Academy of Allergy, Asthma, and Immunology states that antibiotics are not indicated for wasp stings unless there is evidence of secondary infection, with a high strength of evidence 1, 2
The swelling and inflammation following a wasp sting are caused by mediator release and not by infection, therefore antibiotics are not indicated, as recommended by the Infectious Diseases Society of America 1, 2

Secondary infection is uncommon following wasp stings, with a low incidence rate, according to the American Academy of Allergy, Asthma, and Immunology 2
Signs that would warrant antibiotic consideration include progressive redness, increasing pain, purulent discharge, and fever, as indicated by the American Academy of Pediatrics 1, 2

If the child develops extensive swelling around the sting site, continue with oral antihistamines and cold compresses, as recommended by the American Academy of Allergy, Asthma, and Immunology 1, 2
Oral corticosteroids may be considered for severe large local reactions, although definitive proof of efficacy through controlled studies is lacking, with a moderate strength of evidence from the American Academy of Allergy, Asthma, and Immunology 1, 2

Referral to an allergist should be considered if the child has experienced a systemic reaction to the wasp sting, as recommended by the American Academy of Allergy, Asthma, and Immunology 2, 4

Educate the child and parents about insect avoidance measures, such as avoiding bright clothing and scented products, being cautious around bushes and outdoor eating areas, and having known nests removed by professionals, as recommended by the American Academy of Pediatrics 4
