Allergic rhinitis can affect a child’s physical health, reduce their quality of life, sleep and concentration, and impact on school performance. Children with allergic rhinitis are at increased risk of developing asthma. Around 85% of those with asthma have allergic rhinitis, which can complicate diagnosis and management and also increase the risk of hospitalisation for asthma exacerbations. However, appropriate management of allergic rhinitis can improve asthma control. The diagnosis of allergic rhinitis can usually be made on the basis of the patient’s history and examination alone.
