Abstract
Background: Fexofenadine is one of several second-generation H1-antihistamines approved for the treatment of various allergic disorders; however, it shows numerous unique properties that make it an optimal choice for many patients. Objective: To review the pharmacology, efficacy and safety of fexofenadine and the attributes differentiating it from other H1-antihistamines. Methods: We performed a literature search in PubMed/MEDLINE (1966 – March 2009) using the keywords fexofenadine, antihistamine, allergic rhinitis and chronic urticaria. We also reviewed data provided by the manufacturer in addition to reports from various governmental agencies. Results/conclusions: Fexofenadine is devoid of sedative and anticholinergic effects and may offer equivalent or greater efficacy in treating allergic disorders compared with other currently available second-generation H1-antihistamines. In addition, fexofenadine may offer cost savings over other selected H1-antihistamines owing to its recent availability in generic form in the US.
