Abstract
Non-allergic rhinitis is a term used for situations where no allergen can be detected as the cause of rhinitis. In non-allergic rhinitis; Skin test positivity or specific Ig E response cannot be detected. The pathophysiology of nonallergic rhinitis (NAR) is heterogeneous. The most common type is vasomotor rhinitis, also called idiopathic. In addition, there are many types such as hormonal, gustatory, occupational, atrophic, cold air-induced and systemic diseases. Patients; They present with symptoms such as nasal congestion, runny nose, sneezing, and itching in the nose, the symptoms of the patients do not show a seasonal pattern. There are family stories, but they are not as common as allergic rhinitis (AR). An underlying factor such as infection, sinusitis or polyps cannot be detected in patients. It was determined that the patients showed more neurogenic abnormalities in the pathophysiology. These patients have been shown to be hypersensitive to substances with ingredients such as cold air or capsaicin. The diagnosis is made clinically, the onset of the disease is in adolescence. Oral/nasal antihistamines, steroids, leukotriene antagonists are used in the treatment.
