Treatment of Chronic Urticaria in Adolescents

Initial Management Strategy

• Cetirizine 10 mg once daily is effective in reducing wheal formation and pruritus, and may cause mild sedation (13.7% in patients ≥12 years), which can be beneficial for nighttime pruritus, according to the American Academy of Allergy, Asthma, and Immunology 1
• Topical hydrocortisone should be discontinued for urticaria management, as it has no meaningful role in treating hives, and urticaria is a systemic histamine-mediated process affecting dermal blood vessels, as recommended by the British Medical Association 2, 3

Escalation Protocol for Persistent Symptoms

• Doubling the cetirizine dose to 20 mg once daily can significantly improve wheal severity and itching in patients with urticaria refractory to standard doses, with only mild sedation as the primary side effect, according to the American Academy of Allergy, Asthma, and Immunology 1

Important Clinical Pitfalls to Avoid

• Avoid using first-generation sedating antihistamines (diphenhydramine, hydroxyzine) as primary therapy due to significant sedation, anticholinergic effects, and performance impairment, especially problematic for a school-age adolescent, as recommended by the American Academy of Allergy, Asthma, and Immunology 1, 2
• Systemic corticosteroids are not indicated for uncomplicated chronic urticaria and carry unnecessary risks, according to the British Medical Association 2, 3
