About adrenaline devices (Anapen® and EpiPen®)

On this page

ADRENALINE (EPINEPHRINE) IS LIFE SAVING medication for someone experiencing a severe allergic reaction (anaphylaxis).

An adrenaline device contains one dose of adrenaline. 

Adrenaline is the first line emergency treatment for anaphylaxis. Adrenaline devices are designed to be used by anyone in an emergency.

What does adrenaline do?

Adrenaline works quickly to reverse what is happening in the body during a severe allergic reaction.

It increases blood pressure:

  • Tightens blood vessels and reduces fluid leaking out of them
  • Makes the heart beat stronger and faster

It makes breathing easier:

  • Opens the airways

Adrenaline devices are given in the outer mid thigh

There is a large muscle in the outer mid-thigh. Injecting adrenaline into this muscle helps get the adrenaline to the rest of the body quickly. The adrenaline device can be given through clothing.

Remember: hold the leg still if you are giving an adrenaline device to someone else as they may move unexpectantly.

Adrenaline training devices

It is important to practice giving an adrenaline device. Using a training device is a great way to do this. It contains no needle or medication and can be reused.

If your child is at risk of anaphylaxis, practicing with them can help you think about how you may need to hold them if you had to give the adrenaline device. It may also help the child understand what would happen if they had anaphylaxis.

It is important to store you training device away for the real adrenaline devices. You may wish to mark the training device with tape or a sticker to highlight that it is not the real thing.

You can buy Adrenaline training devices from our online shop.

Where to keep your adrenaline devices

It’s important to store adrenaline devices correctly, and to ensure the adrenaline device and ASCIA Action Plan are always with the person at risk of anaphylaxis.

Expiry dates

  • Adrenaline devices usually expire after 12 to 18 months.
  • Expired adrenaline devices are not as effective at treating anaphylaxis (but should still be given if it is the only adrenaline device available).
  • Make a note of when your adrenaline devices are due to expire and book an appointment for a new prescription with your doctor or nurse practitioner.
