Summary

Many children diagnosed with penicillin allergy tolerate penicillin well. Clinical investigation, not just history, is crucial for accurate penicillin allergy diagnosis in pediatric patients.

Area of Science:

  • Allergy and Immunology
  • Pediatric Medicine
  • Pharmacology

Background:

  • Penicillin allergy is frequently diagnosed in children.
  • Adverse reactions to penicillin are common concerns in pediatric care.
  • Accurate diagnosis of penicillin allergy is essential for appropriate antibiotic selection.

Purpose of the Study:

  • To evaluate the actual incidence of penicillin allergy in children with a history of adverse reactions.
  • To determine the safety and tolerance of penicillin V re-challenge in this pediatric population.
  • To assess the long-term outcomes of children previously labeled as penicillin allergic.

Main Methods:

  • Radioallergosorbent test (RAST) for penicillin metabolites.
  • Skin prick testing (SPT) with penicillin V.
  • Controlled oral penicillin V challenge.
  • Long-term follow-up interviews.

Main Results:

  • No severe reactions occurred during oral penicillin challenge.
  • Slight to moderate skin reactions were observed in 10% of subjects.
  • 94% of children tolerated subsequent penicillin treatment well, with no adverse reactions reported during follow-up.

Conclusions:

  • The diagnosis of penicillin allergy is often overused in children.
  • Clinical evaluation, including objective testing and challenge, is necessary to confirm penicillin allergy.
  • Many children presumed to be penicillin allergic can safely receive penicillin medications.
