Allergic rhinitis is activated when the immune system comes in contact with an allergen, such as dust, dander or pollen, and mistakenly identifies it as an intruder.(7) An allergic reaction results, involving the body's release of various inflammatory mediators, including histamine and leukotrienes, as a defense against the allergens, causing symptoms such as sneezing, nasal congestion, runny nose, and itching of the palate, eyes and nose.(8)
