Seasonal allergic rhinitis.

Seasonal allergic rhinitis is characterized by seasonal rhinorrhea, nasal congestion/stuffiness, nasal and ocular pruritus, and paroxysmal sneezing. Symptomatic relief and improved quality of life can be achieved in the majority of patients by using pharmacotherapy appropriately. Mild cases can be managed with either an oral antihistamine or a nasal corticosteroid alone. More severe cases may require a nasal corticosteroid in combination with various agents. Immunotherapy is reserved for a selected group of patients. While all other interventions provide symptomatic relief, specific immunotherapy may have long-term effects.
