Corticosteroids in the management of allergic rhinitis

Allergic rhinitis unresponsive to conservative therapy with antihistamines, decongestants, and environmental control may require the use of corticosteroids for symptomatic relief, even while hyposensitization is being carried out. Such therapy may be given orally, intramuscularly, as a nasal aerosol, or by intraturbinal injection. This discussion deals with the characteristics and appropriate use of each modality.
