Drug hypersensitivity reactions in children in clinical practice: A WAO Statement

testing, risk stratification, and personalized approaches. Antibiotics, particularly β-lactams, and non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequently implicated drugs, with non-immediate reactions, such as maculopapular exanthema, being the most common presentation. The document also addresses emerging concerns, including monoclonal antibody-induced anaphylaxis and drug-induced enterocolitis syndrome. It underscores the need for specialized care in allergy centers with expertise in pediatric populations and advocates for multidisciplinary programs to manage complex cases, such as chemotherapy hypersensitivity and perioperative drug allergy. By addressing diagnostic challenges and clinical uncertainties, this document aims to improve the management of DHRs in children, reduce mislabeling, and enhance patient outcomes worldwide.
