Allergic Rhinitis (Hay Fever) is an allergic reaction that causes sneezing, congestion, itchy nose and sore throat [1]. It is caused by an allergic reaction to substances called allergens such as pollen from trees, grass and weeds (hay fever), house dust mites or animals [4]. When a person with Allergic Rhinitis breathes in an allergen, their body releases histamine which triggers the symptoms of hay fever [5]. Symptoms may include runny nose, itchy eyes, congestion and sneezing [2][3][6][7][10], but do not cause fever. The nasal discharge is thin, watery and clear [9]. Treatment options include avoiding allergens where possible; medications such as antihistamines; immunotherapy; or a combination of these approaches [8].

Allergic rhinitis, commonly known as hay fever, is an allergic reaction to airborne particles such as pollen, dust mites and pet dander. Symptoms of allergic rhinitis include sneezing, runny nose, itchy eyes and throat, congestion and postnasal drip. Treatment for allergic rhinitis includes avoiding triggers when possible (such as staying indoors on high-pollen days), using over-the-counter or prescription medications to reduce symptoms and allergy shots (immunotherapy).
