Hay fever is the common name for a condition called allergic rhinitis, which means an allergy that mainly affects the nose. However, hay fever can also affect your eyes, throat, sinuses and ears.
Seasonal hay fever occurs mainly in spring and summer, and affects people allergic to pollens. Hay fever can also occur all year round – this is called perennial hay fever.
Hay fever is very common, and affects up to 30 per cent of children. Children with hay fever commonly also have other sensitivities, like asthma, eczema or food allergy.
If your child has hay fever, they may have:
If hay fever is left untreated it can lead to poor quality sleep, tiredness and daytime sleepiness. In some cases, hay fever can also:
Hay fever is triggered by what we breathe in. The small hairs and mucus in the nose trap dust, pollens and other tiny particles. Someone with hay fever is allergic to some of the particles that get trapped in their nose.
If your child has perennial (all year) hay fever, they will most likely be allergic to dust mites, animal dander and/or mould spores.
Hay fever cannot be cured, but there are a number of ways you can improve the symptoms and give your child some relief.
The best way to reduce the frequency of your child's hay fever is to identify what causes your child's allergic reaction and then try to avoid contact with it, or at least minimise contact.
Sometimes the cause is obvious, such as a pet. If you are having trouble working out the cause of your child's hay fever, see your GP. The doctor will ask questions and may suggest allergy tests (such as skin prick tests) to identify the cause.
If your child is allergic to pollen, checking the pollen count for your region can help you be aware when your child's hay fever might be worse.
Your doctor may suggest using medication to help relieve your child's symptoms, such as:
Your doctor or pharmacist can give advice on which medication may be best for your child.
Immunotherapy may be a suitable treatment option if your child has severe hay fever. Immunotherapy is a long-term treatment that involves exposing your child to small amounts of the allergen (the substance they are allergic to). This allows your child to gradually build up their
tolerance to the allergen. Talk to your doctor about immunotherapy if your child has serious allergic reactions.
Are skin prick tests reliable?
Skin prick testing can be helpful for working out what your child is allergic
to. If the skin test is negative this suggests that the allergen tested is not
the cause of the hay fever. However, some children will have a positive allergy
test but do not develop symptoms when exposed to the allergen. Your child's
allergist will discuss the findings with you.
Are nasal steroid sprays safe to use?
Nasal steroid sprays are the most effective medicine
available for hay fever, and some products are safe for use in children. Talk
to your doctor or pharmacist about which products can safely be used on your
child. Always follow the instructions on the packaging. Some nasal steroids are
only suitable in children over two years old, and some are not recommended for
children under 12 years old.
What does immunotherapy involve?
If your child is having immunotherapy, they will
be given a small amount of the allergen, either by injection
or orally in tablet or liquid form. A typical treatment course requires monthly
injections over a period of three to five years, or taking the allergen orally
each day for two to three years. Immunotherapy may be suitable for older
children whose symptoms are not well controlled by antihistamines and steroid
nasal sprays. Before starting immunotherapy, it is important that your child's
allergens are clearly identified.
