Nonallergic rhinitis is inflammation of the inner part of the nose that is not caused by an allergy. Nonallergic rhinitis involves symptoms including chronic sneezing or having a congested, drippy nose without an identified allergic reaction. Other common terms for nonallergic rhinitis are vasomotor rhinitis and perennial rhinitis. The prevalence of nonallergic rhinitis in otolaryngology is 40%. Allergic rhinitis is more common than nonallergic rhinitis; however, both conditions have similar presentation, manifestation and treatment. Nasal itching and paroxysmal sneezing are usually associated with nonallergic rhinitis in comparison to allergic rhinitis. Types
Rhinitis medicamentosa – rebound nasal congestion suspected to be brought on by extended use of topical decongestants and certain oral medications that constrict blood vessels in the nose. Treatment includes withdrawal of nasal drops, short courses of systemic steroid therapy and in some cases, surgical reduction of turbinates, if they have become hypertrophied. Rhinitis of pregnancy – pregnant women may develop persistent rhinitis due to hormonal changes. Nasal mucous become edematous and block the airway. Some may develop secondary infection and even sinusitis in such cases. Care should be taken while prescribing drugs. Generally, local measures such as limited use of nasal drops, topical steroids and limited surgery (cryosurgery) to turbinates are sufficient to relate the symptoms. Safety of developing fetus is not established for newer antihistamines and they should be avoided. Honeymoon rhinitis – this usually follows sexual excitement, leading to nasal stuffiness.
A Cochrane review concluded that it is unclear whether intranasal corticosteroids, when compared with a placebo, reduce patient‐reported disease severity in people with nonallergic/vasomotor rhinitis due to the low certainty of the evidence available from clinical trials. However, intranasal corticosteroids probably increase risk of nosebleeds.Astelin (azelastine) "is indicated for symptomatic treatment of vasomotor rhinitis including rhinorrhea, nasal congestion, and post nasal drip in adults and children 12 years of age and older." Surgical
Reduction of hypertrophied turbinates, correction of nasal septum deviation, removal of polyps, sectioning of the parasympathetic secretomotor fiber to nose (vidian neurectomy) for controlling refractory excessive rhinorrhea. See also
