Symptoms of an allergic reaction to an insect sting may appear right away, or may be delayed as much as four hours to a week later. Symptoms may be minor, or may manifest as a potentially life-threatening reaction known as anaphylactic shock. Children are more likely than adults to suffer reactions to insect stings, as the venom can more powerfully affect their lower body mass and smaller airways.   

Parents should seek immediate medical help if their children are stung and experience any of the following symptoms:

• Sudden breathing difficulties (e.g., shortness of breath, wheezing)
  
• Dizziness
  
• Weakness, collapse or unconsciousness
  
• Hives
  
  

  

• Severe swelling of the eyes, lips or genitals (angioedema)
  
  

  

  
  
• Stomach cramps
  
• Nausea
  
• Vomiting
  
• Diarrhea
  
• Low-grade fever

Young children suffering a severe allergic reaction may not be able to express the symptoms they are experiencing to a parent or other caregiver. Hoarseness, difficulty talking, coughing, choking and drooling may suggest that the child is experiencing anaphylaxis.

Parents should also seek immediate medical help for a child stung in the mouth, on the face or on the neck. A child who has had severe reactions to an insect sting in the past should receive emergency medical attention as well.
