Hay fever is one of the spectrum of allergic diseases that includes eczema and asthma (Wahn, 2015). It is a common condition and the symptoms are distressing and in severe cases may be extremely debilitating. Symptoms may impact upon work, study, outdoor activities and sleep — in fact, the whole lifestyle of a severely affected individual.

Depending on the cause and severity, treatment may be wholly or partially effective. The aim of treatment by avoidance, desensitisation or medication is to minimise or abolish symptoms, while also ensuring that side-effects of medication(s) are minimised. Where the specific trigger or allergen has been identified and had a seasonal effect, it is best practice to start treatment before the season begins.
