Hay Fever (Allergic Rhinitis) in Children — Belfast
Private assessment and management of hay fever and allergic rhinitis in children in Belfast and Northern Ireland. Dr Mugilan Anandarajan, Consultant Paediatrician, offers allergy testing, personalised treatment plans, and advice on allergen immunotherapy.
What is Hay Fever?
Hay fever (seasonal allergic rhinitis) is an allergic reaction to airborne pollen from grasses, trees, and weeds. It is one of the most common allergic conditions in children, affecting up to 1 in 5 school-age children in the UK.
Perennial allergic rhinitis causes similar symptoms year-round and is triggered by indoor allergens such as house dust mite, pet dander, and mould spores.
Hay Fever & Exams
The peak grass pollen season (May–July) coincides with GCSE and A-level examinations. Poorly controlled hay fever can significantly impair concentration and exam performance. Early treatment is important.
Symptoms
- Persistent sneezing
- Runny or blocked nose
- Itchy nose, mouth, or throat
- Itchy, red, or watery eyes (allergic conjunctivitis)
- Postnasal drip and throat clearing
- Fatigue and poor sleep
- Difficulty concentrating at school
- Worsening of asthma symptoms during pollen season
Pollen Seasons in Northern Ireland
Tree Pollen
February – May
Birch, alder, hazel, oak
Grass Pollen
May – August
Timothy, ryegrass, meadow grass
Weed Pollen
June – September
Nettle, dock, mugwort, plantain
Allergy testing can identify which specific pollens your child is sensitised to, allowing targeted treatment and avoidance advice.
What Happens at the Consultation?
Clinical History
Detailed history of symptoms, their seasonal pattern, potential triggers, current medications, impact on sleep and school, and family history of allergy.
Allergy Testing
Skin prick testing with a panel of grass, tree, and weed pollens, and/or specific IgE blood tests to identify which pollens are causing symptoms.
Assessment for Asthma
Assessment for co-existing asthma, which is common in children with hay fever. Lung function testing if indicated.
Treatment Plan
Personalised treatment plan including intranasal corticosteroid spray, antihistamines, eye drops if needed, and discussion of immunotherapy for eligible children.
Treatment Options
Intranasal corticosteroid sprays
First-line treatment for allergic rhinitis. Reduce nasal inflammation and congestion. Most effective when started 2 weeks before the pollen season.
Non-sedating antihistamines
Relieve sneezing, itching, and runny nose. Cetirizine or loratadine are commonly used in children.
Antihistamine eye drops
For allergic conjunctivitis (itchy, watery eyes). Sodium cromoglicate or antihistamine drops.
Allergen avoidance
Practical advice on reducing pollen exposure — checking pollen forecasts, keeping windows closed during high pollen periods, showering after outdoor activities.
Allergen immunotherapy (AIT)
Sublingual grass pollen tablets (e.g. Grazax) or subcutaneous injections for children with moderate-to-severe hay fever not controlled by standard treatment. Requires 3-year commitment.

Frequently Asked Questions
What is hay fever (allergic rhinitis) in children?
Hay fever, or seasonal allergic rhinitis, is an allergic reaction to airborne allergens — most commonly grass pollen, tree pollen, and weed pollen. It causes inflammation of the lining of the nose and eyes. Perennial allergic rhinitis is a year-round form caused by indoor allergens such as house dust mite, pet dander, and mould. Both forms are very common in children and can significantly affect quality of life, sleep, and school performance.
What are the symptoms of hay fever in children?
Symptoms include persistent sneezing, runny or blocked nose, itchy nose, itchy and watery eyes (allergic conjunctivitis), postnasal drip, and throat clearing. Children may also experience fatigue, poor sleep, and difficulty concentrating — particularly during the pollen season. Hay fever can also trigger or worsen asthma in children with both conditions.
At what age can children develop hay fever?
Hay fever can develop at any age but is uncommon before the age of 2–3 years. It becomes increasingly common from school age onwards. Many children with eczema or food allergy develop hay fever as they get older — this progression of allergic conditions is known as the "atopic march".
Do I need a GP referral to see Dr Anandarajan about my child's hay fever?
No. You can book directly without a GP referral. Dr Anandarajan sees children aged 0–16 with hay fever and allergic rhinitis at Kingsbridge Private Hospital and Ulster Independent Clinic in Belfast.
How is hay fever diagnosed?
Diagnosis is primarily clinical, based on the history of symptoms and their seasonal pattern. Allergy testing — skin prick testing (SPT) or specific IgE blood tests — can confirm sensitisation to specific pollens or other allergens and help guide management. Testing is particularly useful when the trigger is unclear, when symptoms are perennial, or when allergen immunotherapy is being considered.
How is hay fever treated in children?
First-line treatment includes intranasal corticosteroid sprays (e.g. fluticasone, mometasone) for nasal symptoms, and non-sedating antihistamines (e.g. cetirizine, loratadine) for sneezing, itching, and runny nose. Eye drops (sodium cromoglicate or antihistamine drops) are used for allergic conjunctivitis. For children with poorly controlled symptoms, allergen immunotherapy (desensitisation) may be considered.
Can hay fever affect my child's school performance?
Yes. Studies have shown that hay fever can significantly impair concentration, memory, and exam performance in children. The peak pollen season in Northern Ireland (May–July) coincides with GCSE and A-level examinations. Effective treatment of hay fever during this period is important to minimise its impact on academic performance.
What is allergen immunotherapy and is it suitable for children?
Allergen immunotherapy (AIT) — also known as desensitisation — involves giving gradually increasing doses of the allergen (e.g. grass pollen) to reduce the immune response over time. It is available as subcutaneous injections (SCIT) or sublingual tablets/drops (SLIT). It is considered for children with moderate-to-severe hay fever that is not adequately controlled with standard treatment. It requires a commitment of 3 years of treatment but can produce long-lasting benefit. Dr Anandarajan can advise on whether immunotherapy is appropriate for your child.
