Hayfever

Hayfever, also known as seasonal allergic rhinitis, is a very common condition, affecting between 10-20% of the population. It is caused by an allergy to pollen or sometimes mould spores.

The body’s immune system over reacts to the allergen, as if it is something toxic. This results in irritation and inflammation. Hayfever often runs in families and is also related to asthma and eczema.

Symptoms vary in severity and start at different times of the year depending on the type of pollen or allergen causing the reaction. Common symptoms include sneezing, runny/blocked nose, red, watery and itchy eyes and an associated itchy throat. Poorly controlled hayfever can lead to poor quality sleep and daytime fatigue as well as undermining performance at school and work. Hayfever can affect a sufferer’s quality of life for several months of the year.

For those people who are allergic to tree pollens, symptoms can start as early as January. The grass pollen season normally runs from May to the end of July when pollen counts are highest. Fungal spores are present all year but counts are highest in late summer and autumn.

Treatment

As with all allergies, the first step to reducing symptoms is to try to avoid the allergen (see prevention advice). There are also a number of products available from your pharmacy to treat the symptoms of hayfever.

Antihistamines are available as tablets or liquids and may be sedating, (causes drowsiness) and non-sedating, (causes less drowsiness). They work by blocking the release of histamine, a chemical released by the body which causes the allergic reaction of irritation in the eyes and nose.

Check with your pharmacist to see if antihistamines are suitable for you. Steroid nasal sprays help to prevent hayfever symptoms and can therefore be used at the first onset of symptoms or when you know symptoms are likely to occur.

These products can be very effective when used regularly. Eye drops act by reducing the release of histamines from the eyes and help to reduce itching and swelling. These often contain the active ingredient sodium cromoglycate.

Prevention

There are several things you can do to lessen symptoms by avoiding contact with all allergens. These include:

  • Keep windows at home, in the office and in the car closed.
  • Use an air conditioner or filter when possible at home, work and in the car to remove pollen
    from the air.
  • Wear sunglasses to prevent pollen reaching the eyes.
  • Avoid pollen-rich areas, particularly when the pollen count is at its highest in the afternoon
    and evening.
  • Shower and wash hair to remove pollen after being outside.
  • Check pollen forecast in the media.
