Adrenaline Auto-Injectors

Adrenaline auto-injector devices (“adrenaline pens”) are medical devices which deliver a single dose of adrenaline (epinephrine). They have been designed to be easily administered to a person who is having a severe allergic reaction (anaphylaxis).

If you have been prescribed an adrenaline auto-injector, carry them with you at all times. Your GP, or Allergy Service should discuss how to manage an allergic reaction, including how and when to use the adrenaline auto-injector device. Your family, friends, teachers and colleagues should also know how and when to give your adrenaline, in case you become unable to give it yourself. It is advisable to buy a placebo device for regular practice.

There are three different devices are available in the UK, and they all deliver the same medicine, in one of two doses (a paediatric dose for younger children and an adult dose for older children and adults). They are available on prescription from your GP or allergy specialist.

Remember The MHRA advises that people who have been prescribed and auto injector of adrenaline because of the risk of anaphylaxis should carry two with them at all times for emergency use.  You may need a second dose, if the first one fail to work.

Always keep your pens with you and always call an ambulance if you have used your adrenaline pen.

Adrenaline is a short-acting drug and the effects will wear off quite quickly. It is very likely that further treatment will be required. All patients receiving emergency adrenaline should immediately be transported to hospital. Dial 999 and inform the controller that the patient is suffering from anaphylaxis.
