Allergic rhinitis affects a large portion of the population. These patients often suffer from daytime fatigue, both as a result of the mechanics of the nasal airway in patients with allergic rhinitis as well as through central effects on sleep by immune mediators. By understanding these mechanisms and by becoming familiar with effective treatments for allergic rhinitis that are beneficial in alleviating rather than worsening daytime somnolence, physicians may improve patient quality of life.
