Children's Allergy & Hayfever

Shopping for children’s hayfever relief and allergy support? This range includes commonly used pharmacy options to support symptom relief for sneezing, an itchy or runny nose, and watery or irritated eyes. You’ll find child-friendly formats alongside some products that are only suitable from certain ages (for example 6+ or 12+), so always check the label and patient information leaflet before you buy.

Whether you’re preparing for pollen season or dealing with year-round triggers like dust mites or pets, you can compare ingredients, pack sizes and dosing guidance in one place. withaid is a UK based and regulated pharmacy with discreet delivery options, and some medicines may require a short suitability check so a pharmacist can help confirm they’re appropriate for your child.


Shop by Children's Allergy & Hayfever type

Popular types of children's allergy products

  • Once-daily antihistamine tablets often chosen for daytime routines (check age suitability)
  • Liquid antihistamine syrups / oral solutions for children who prefer a non-tablet format
  • Shorter-acting antihistamines taken as directed in the leaflet
  • Allergy eye drops designed for eye-focused irritation such as itching and watering
  • Nasal sprays used when congestion or a blocked nose is the main symptom

How to choose the right option

  • Start with the main symptom: antihistamines for broader symptoms, eye drops for eye irritation, and nasal sprays for congestion or a blocked nose.
  • Check the minimum age and dose: children’s medicines are age-specific; follow the pack and leaflet carefully.
  • Consider drowsiness warnings: some antihistamines can cause sleepiness, which may affect school, sports or activities.
  • Choose an easy format: liquids can suit younger children; tablets may suit older children.
  • Avoid duplicating active ingredients: check labels carefully if using more than one product type for different symptoms.
  • Reduce exposure where possible: check pollen forecasts, keep windows closed at peak times, and consider washing hair/face after outdoor play during high pollen days.

FAQs

What are common triggers for children's hayfever and allergies?

Seasonal symptoms are often linked to pollen (trees, grasses or weeds). Year-round allergies can be triggered by dust mites, pets or mould. Triggers vary, so noting when symptoms appear can help you choose a suitable format.

Which symptoms can children's allergy products help with?

Depending on the product, options may help relieve sneezing, an itchy or runny nose, watery eyes and allergy-related irritation. Hayfever is also known as allergic rhinitis. Choose a product that matches your child’s main symptoms and follow the directions on the pack and leaflet.

Which is better for children: cetirizine or loratadine?

Both are commonly used antihistamines, but what’s suitable depends on your child’s age, symptoms and the specific product instructions. If you’re unsure which to choose, a pharmacist can help you compare options and check suitability.

Are tablets or liquid antihistamines better for children?

It depends on your child’s age, preference and the product directions. Liquids can be easier for younger children, while tablets may suit older children. Always check the minimum age, dose and frequency for the specific medicine.

Can children's antihistamines cause drowsiness?

Some antihistamines may cause sleepiness, while others are described as non-drowsy. Effects can vary, so take extra care when trying a new product and follow the leaflet guidance.

What if my child is under 6?

Many allergy and hayfever medicines have minimum age limits. Check the label and leaflet carefully and choose an age-appropriate product. If symptoms are affecting sleep or daily life, ask a pharmacist for advice on suitable options and non-medicine measures.

When should I speak to a pharmacist or GP about my child's symptoms?

Get advice if symptoms are persistent, severe, affecting sleep or breathing, or if your child is very young. Seek urgent medical help for signs of a serious allergic reaction, such as swelling of the face or lips, wheezing, difficulty breathing, or collapse.

Safety information: Always read the label and patient information leaflet before use. Children’s medicines are age-specific—use only as directed and do not exceed the stated dose. Stop use and seek medical advice if your child develops wheezing, breathing difficulty, facial swelling, or symptoms that are severe or not improving. If you’re unsure what’s suitable, ask a pharmacist or contact your GP.
