Approach to management of nonallergic rhinitis

In patients with nonallergic rhinitis caused by a clinically obvious irritant, minimise exposure to the irritant if possible. Exclude other causes of rhinitis, such as rhinitis medicamentosa caused by overuse of intranasal decongestants.

Topical antihistamines and oral antihistamines are not indicated for nonallergic rhinitis.

Intranasal corticosteroids are the mainstay of treatment. Dosages are the same as those used for allergic rhinitis; see here.
