Like any other allergy, allergic rhinitis is an inappropriate immune system response to an allergen - most commonly house dust mite, pet dander, pollen and mould.
About 20% of the general population suffers from allergic rhinitis. Of these people, about one third develops problems before the age of 10.
This leaflet discusses the symptoms, how to get a diagnosis and treatment options.
