Question: what is the best treatment for non-allergic rhinitis?
Answer: Try a prescription antihistamine spray such as azelastine (Astelin, Astepro) and olopatadine hydrochloride (Patanase). While oral antihistamines don't seem to help nonallergic rhinitis, nasal sprays containing an antihistamine may reduce symptoms of nonallergic rhinitis. Anti-drip anticholinergic nasal sprays.
