Hay fever is an allergic reaction to pollen, typically when it comes in contact with your mouth, nose, eyes and throat. It affects up to 1 in 5 people at some point in their life.

Treatment aims to manage symptoms and avoid the causes.
Antihistamines syrups or tablets are usually divided into 2 main groups:
Antihistamine eyedrops can be helpful for eye symptoms. Some of these can be purchased from a pharmacy e.g sodium cromoglycate and others are available on prescription
Corticosteroid nose sprays are the best treatment for hay fever, especially for a blocked nose. Your child can use them safely throughout the pollen season for seasonal hay fever, or throughout the year for perennial rhinitis.Some of these can be purchased from a pharmacy and others are available on prescription.
Severe rhinitis caused by pollen or dust that won't go away, your doctor might consider sending your child to a specialist for immunotherapy. Immunotherapy is also known as desensitisation and aims to change the body's immune system and switch off the allergy. This will usually be done under the supervision of a doctor with experience in allergy and started at a hospital.
Hay fever symptoms are more common in young people. At present, it is not possible to predict whose hay fever will get better and whose will remain. Some patients will also suffer from asthma and require inhalers.
People with hay fever do not have allergies to all pollens. Pollen from different plants vary during the year. Tree pollen tends to be highest in spring, grass pollen is highest in summer and many weed pollens are highest in autumn:
