Nonallergic Rhinitis and its Management

The constellation of symptoms of rhinorrhea, nasal congestion, and nasal irritation, called rhinitis, can be related to non-allergic or allergic rhinitis. Non-allergic rhinitis is currently of diagnosis of exclusion. We validated the use of nasal provocation with intranasal capsaicin and an optical rhinometer, a device allowing for a non-invasive means of measuring blood flow through the nasal cavity and providing a means of evaluating nasal congestion, for the diagnosis of non-allergic rhinitis. We are currently conducting a clinical trial investigating the clinical efficacy of intranasal capsaicin for the management of nonallergic irritant rhinitis.
