The UK has one of the highest percentages of people with allergies in the world, so it is likely that you will come into contact with someone who may be at risk of suffering a severe allergic reaction after coming into contact with a certain substance or food.

When allergies are severe this may result in an anaphylactic reaction. Someone who has an anaphylactic reaction is going to need a dose of adrenaline very quickly. Using conventional syringes takes way too much time, and if you yourself are having an anaphylactic attack, there is no way you will cope with drawing a drug out of a bottle in the same way a trained doctor would do. This is why auto-injectors are so useful.

There are many types of auto-injectors, and the most common ones are very easy to handle and use. They are available to anyone who could suffer from anaphylaxis. The auto injector will, when used properly, administer a set amount of adrenaline to the person suffering an anaphylactic reaction. Even though there are many types of auto injector, they should all be administered into the top quarter of the thigh. The main 3 auto injectors being used are the EpiPen®, the Jext® and the Emerade® and later on we will look into the differences between them.
