Multidisciplinary Real-World Experience With Bilastine, a Second Generation Antihistamine

Introduction: Allergic conditions frequently require treatment with antihistamines. First-generation antihistamines can potentially interfere with restful sleep, cause "morning after" effects, impair learning and memory, and reduce work efficiency. Second-generation antihistamines, such as bilastine, have been demonstrated to decrease allergy symptoms effectively without causing night-time sleep disturbances and related adverse events. Method: A real-world case project was developed to help optimize patient care by recognizing the role bilastine can play for allergic conditions where antihistamine treatment is needed. The presented real-world patient cases conducted by the panel members are supported with evidence from the literature, where available. Any discussion concerning off-label use should be considered an expert opinion only. Results: The real-world cases presented here used bilastine in conditions such as perennial and seasonal allergic rhinitis, chronic urticaria, as well as urticarial vasculitis and pruritus associated with inflammatory skin conditions. The treated patients were between 9 and 76-years old providing information on a full spectrum of patients that require treatment with antihistamines. Conclusions: The presented real-world cases using the second-generation antihistamine, bilastine, demonstrated favorable outcomes for the treated patients. While effectively relieving symptoms, the antihistamine was reported to be safe and well-tolerated. J Drugs Dermatol. 2020;19(2)145-154. doi:10.36849/JDD.2020.4835
