Adrenaline auto-injectors

Adrenaline autoinjector EpiPen

What is an adrenaline auto-injector?

The most effective first aid treatment for anaphylaxis is adrenaline given using an auto-injector (such as an EpiPen®) into the outer mid-thigh muscle. Adrenaline auto-injectors are designed for use by non-medical people so that anyone can use them in an emergency.

What is anaphylaxis?

Anaphylaxis is the most severe form of allergic reaction and is potentially life threatening.

It should be treated as a medical emergency, requiring immediate treatment.

About adrenaline auto-injectors

  • Designed to give a single fixed dose of adrenaline into the outer mid‑thigh.
  • Can be administered through a single layer of clothing.
  • Temperature sensitive – store at (15 to 25 °C). Do not refrigerate. Do not leave in heat.
  • Shelf life of approximately is 12 to 18 months.
  • Only the EpiPen® is currently available in Australia.

How to treat anaphylaxis using an adrenaline autoinjector

  • Lay the person flat and do not allow them to stand or walk.
  • If breathing is difficult, allow the person to sit. If they are unconscious or vomiting, place them on their side in the recovery position.
  • Without delay, administer an adrenaline auto injector (EpiPen®) into the patient’s outer mid-thigh.

Instructions for how to administer EpiPen. Step 1 pull off blue safety release. Step 2 push orange end hard into outer thigh so it clicks and hold for 10 seconds. After administering EpiPen, call 000

It is important to practise regularly with an adrenaline auto-injector trainer device

People with anaphylaxis and their carers are encouraged to regularly practise how to use the prescribed adrenaline auto-injector using an adrenaline-auto injector trainer device. The trainer device:

  • does not contain adrenaline
  • does not have a needle
  • simulates the injecting action and ‘click’ sound
  • can be repeatedly reset.

A complementary trainer device is provided to you when you join EpiClub (external site)

Adrenaline auto injector trainer devices are also available from Allergy & Anaphylaxis Australia’s (external site).

How do I get an adrenaline auto-injector through the Pharmaceutical Benefits Scheme (PBS)?

Adrenaline auto-injectors are prescribed to patients assessed to be at risk of anaphylaxis.  A personal ASCIA Action Plan for Anaphylaxis (external site) should be completed by the person’s medical doctor at time of prescribing an adrenaline auto-injector. 

Adrenaline auto-injectors are available on a Pharmaceutical Benefits Scheme (PBS) (external site) authority prescription. The authority prescription is provided by, or in consultation with, a specialist, with a maximum of 2 adrenaline auto-injectors per patient at any one time. No repeats can be issued. Renewal is required prior to the device’s expiry.

Continuing PBS authority prescriptions for adrenaline auto-injectors can be provided by your GP. If required, additional devices can be purchased at full price over the counter from a pharmacy.

A prescription will be provided upon discharge from a hospital or emergency department following treatment for anaphylaxis with adrenaline.

Disposing of adrenaline auto-injectors

Used adrenaline auto-injectors that have been administered to treat anaphylaxis can be handed over to the ambulance officer when they arrive for the patient. It is also important to report to the ambulance officer the time at which each adrenaline auto injectors was administered.

Adrenaline auto-injectors that cannot be used (for example, if they have expired, have been accidentally fired or the liquid is discoloured or contains granules) should be disposed of appropriately.

Community pharmacies participate in a return of unwanted medicines service, and can accept medicines for disposal. Your local public hospital also has biohazard bins (yellow or purple), and can dispose of adrenaline auto injectors for you.

Where to get help

  • If you have severe symptoms, always dial triple zero (000) to call an ambulance in a medical emergency
  • See your doctor
  • Visit a GP after hours
  • Ring healthdirect on 1800 022 222

Remember

The most effective first aid treatment for anaphylaxis is adrenaline given using an adrenaline auto-injector.
