Seasonal allergic rhinitis is characterized by seasonal rhinorrhea, nasal congestion/stuffiness, nasal and ocular
pruritus, and paroxysmal sneezing. Allergen avoidance is the first step in the management. Symptomatic relief and improved
quality of life can be achieved in the majority of patients by the appropriate use of pharmacotherapy. Mild to moderate
cases can be managed with either an oral/intranasal second generation antihistamine or an intranasal corticosteroid
alone. More severe cases may require treatment with an intranasal corticosteroid in combination with various agents. Patients
who require medications for more than 6 months per year, two or more seasons of unacceptable pollinosis, or have
intolerable side effects from pharmacotherapy, especially those with co-morbid conditions are candidates for immunotherapy.
