Updates in Pediatric Drug Allergy

Key Points

To provide an overview of recent international updates in the classification, diagnosis, and management of pediatric drug allergies, particularly focusing on antibiotics and NSAIDs.
Reviewed guidelines for standardizing nomenclature and classification of drug allergies.
Outlined the new standard amoxicillin dose for direct provocation challenges.
Discussed a defined severity scale for immediate reaction assessments.
Highlighted changes in skin testing practices in favor of direct oral challenges.
New guidelines encourage the use of standard doses and rapid challenges for amoxicillin.
Skin testing is being replaced with more efficient oral challenges conducted in a single day.
The threshold for drug provocation challenges has decreased for those showing serum sickness-like reactions.
Emphasis on further research into reaction phenotypes and safety of drug challenges.

Abstract

This review is aimed to update clinical allergists on recent international changes in classification, diagnosis, and management of pediatric drug allergy with a focus on antibiotics and NSAID allergy labels. Guidelines have begun to standardize nomenclature, classification, and diagnostic approaches. In a progressive update, there is now a standard amoxicillin dose for direct provocation challenges, a defined severity scale for immediate reactors, and decreased threshold to drug provocation challenges for patients with serum sickness like reactions. Within antibiotic allergy label investigation, skin testing is being bypassed in favor of direct oral challenges performed in a single day without the use of extended challenges. Continued investigation of the index reaction phenotypes, safety of drug challenges, and diagnostic certainty of in vitro studies will continue to advance the field of pediatric drug allergy.
