While some patients with allergic rhinitis can be managed fairly conservatively, for many patients this disease represents a major burden in their lives and puts them at risk for greater co-morbidity. Treatments can include immediate symptom relief but preferably pediatricians should consider approaches that aim for long-term modification of these diseases.
