CAP: St John Ambulance gives advice on how to treat an allergic reaction

This week – recognising and dealing with allergic reactions.

An allergy is an abnormal reaction to an allergen or trigger substance. One of the most common allergens is plant pollen which often causes hay fever. Other allergens include animal hair, bee stings, medication (especially penicillin) and food such as nuts and shellfish.

Allergies develop when the body has an abnormal immune response to a normally harmless substance and mistakes it for a threat, like an infection, and tries to fight it off.
