Advances in Histamine-Mediated Allergy Management: Expanding Perspectives on Cetirizine’s Therapeutic, Safety, and Toxicological Implications

Cetirizine, a second-generation H1 receptor antagonist, has been shown to be highly effective in treating various emerging allergic conditions, including food allergies, atopic dermatitis, allergic conjunctivitis, and drug-induced hypersensitivities. Its combination with other treatments like leukotriene receptor antagonists and corticosteroids has yielded positive results in severe cases. While generally well-tolerated, cetirizine requires dose adjustments for certain populations to avoid adverse effects. Recent advancements in drug delivery systems and pharmacogenomics have enhanced its bioavailability and allowed for personalized therapy. Cetirizine remains a cornerstone in allergy management, with its role expanding in both clinical and toxicological contexts.
