Summary: Allergic rhinitis is the most common chronic airway disease in children and very common in adults. Although its pathogenesis is well understood, and the treatment approach is robust, many patients are undertreated. Allergic rhinitis may have several important consequences, including but not limited to bronchial asthma. In fact the most common of them are chronic sinusitis and upper respiratory tract infections often misdiagnosed as asthma. The review focuses on a simple, efficient and safe therapeutic approach. In our opinion, early and efficient treatment of rhinitis may prevent sequelae. Nasal steroids are the treatment of choice in many situations, including allergic rhinitis and acute and chronic rhinosinusitis.
