Anaphylaxis Management and Prevention

Immediate Post-Episode Requirements

The American Academy of Pediatrics recommends prescribing two doses of epinephrine autoinjector before discharge from any healthcare facility, with dosing of 0.15 mg for patients weighing 10-25 kg and 0.3 mg for patients ≥25 kg 1
Patients must carry autoinjectors at all times, as anaphylaxis is unpredictable and can occur with accidental allergen exposure 2, 3
A monitoring system should be established for tracking autoinjector expiration dates 1
Patients should receive a written anaphylaxis emergency action plan detailing recognition of symptoms and step-by-step treatment 1, 3
The American Academy of Pediatrics emphasizes that delayed epinephrine administration is associated with fatalities, and injection should occur at the first sign of anaphylaxis 1, 4

Referral to an allergist-immunologist is mandatory for all patients post-anaphylaxis, according to the American Academy of Allergy, Asthma, and Immunology 2, 5
The allergist-immunologist should identify allergic triggers through comprehensive allergy diagnostic testing 2
Evaluation for allergen-specific immunotherapy, assessment for desensitization protocols, management of recurrent or difficult-to-control symptoms, and evaluation when diagnosis is incomplete or uncertain should also be performed 2

The American Academy of Pediatrics identifies adolescents and young adults as the highest risk demographic for fatal anaphylaxis 1
Patients with concomitant asthma, especially poorly controlled or severe, are also at increased risk 1, 3
Those with a previous history of anaphylaxis or known allergy to peanuts, tree nuts, fish, or crustacean shellfish are at higher risk 1

The American Academy of Allergy, Asthma, and Immunology states that avoidance is the most effective treatment for most causes of anaphylaxis 2
Intensive education regarding specific allergen avoidance based on identified triggers should be provided 2
For food allergies, education on reading labels, cross-contamination risks, and restaurant dining precautions is necessary 1

Regular follow-up with an allergist-immunologist to reassess triggers and management strategies is recommended 2, 5
Periodic retraining on autoinjector use is necessary, as many patients and caregivers demonstrate incorrect technique despite prior training 3
Continuous assessment for development of new allergies or changes in sensitivity should be performed 2
The American Academy of Pediatrics emphasizes that any anaphylaxis episode requires immediate epinephrine injection followed by emergency department evaluation, even if symptoms improve 1, 4
