Answer

Response to treatment with antihistamines supports the diagnosis of allergic rhinitis, although sneezing, itching, and rhinorrhea associated with nonallergic rhinitis can also improve with antihistamines. [35]

Response to intranasal corticosteroids supports the diagnosis of allergic rhinitis, although some cases of nonallergic rhinitis (particularly the nonallergic rhinitis with eosinophils syndrome [NARES]) also improve with nasal steroids.
