Non-allergic rhinitis is characterized by sporadic or persistent perennial nasal symptoms that do not result from IgE-mediated immunopathologic events. The symptoms can be similar to allergic rhinitis, but with a less prominent nasal itch and conjunctival irritation. The database analysis revealed high hyper-reactivity prevalence in AR (63.4%) and NAR (66.9%). There were no differences between AR and NAR in terms of the number or type of hyper-reactivity stimuli. Hyper-reactivity to physical stimuli did not exclude a response to chemical stimuli, or vice versa. CDA provocation resulted in a significant increase in rhinitis symptoms and the amount of nasal secretions in AR and NAR patients, but not in controls.
Avoidance of inciting factors such as sudden in temperature, humidity, blasts of air or dust.Intranasal corticosteroids and intranasal antihistamines are useful. 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 rhinorrhoea. For patients with non-allergic rhinitis, the treatment is: Use a barrier nasal emollient to prevent the airborne irritants from coming into contact with the nasal lining in the first place. The only FDA-approved medication to treat non-allergic rhinitis is the prescription nasal spray Astelin which is an anti-histamine nasal spray.
