vasomotor rhinitis, chronic rhinitis and nasal obstruction, without allergy or infection, characterized by sneezing, rhinorrhea, nasal obstruction, and vascular engorgement of the mucous membranes of the nose. A vaporizer or humidifier and systemic vasoconstrictive agents are used to alleviate discomfort. Nose drops and nasal sprays should be avoided because continued use may cause further vasodilation of the mucous membrane and aggravation of the condition. Topical vasoconstrictors should also be avoided because the nasal mucous membrane loses sensitivity to stimuli. Vasomotor rhinitis is common in pregnancy.
