Currently, the only adrenaline injector available in Australia is EpiPen® and EpiPen®Jnr.
Anapen® 500 is unavailable and Anapen® 150 and 300 have been discontinued.
From February 2026 neffy® 1mg and 2mg devices will be available on private prescription only. We anticipate they will become available on PBS prescription and over the counter in the future.
If someone is experiencing anaphylaxis, an adrenaline device (injector or nasal spray) should be given.
If the prescribed dosage or brand of adrenaline device is not available, any available adrenaline device should still be given using the following dosing guide. This includes any brand (Anapen® or EpiPen® or neffy®).
Injector devices:
| In children 7.5kg–20kg (around 1–5 years of age) | An adrenaline injector containing 150 mcg of adrenaline should be used (EpiPen® Jr). However, if only a higher dose injector is available (containing 300 mcg) this should be used rather than not using one at all. |
| In children over 20kg (aged around 5 years or over) | A device containing 300 mcg of adrenaline should be used. However, a 500 mcg device can be given if an injector containing 300 mcg of adrenaline is not available. If only an EpiPen® Jr (150 mcg) is available, this should be used rather than not using one at all. |
| In children and adults over 50kg | A device containing either 300 mcg (EpiPen®) OR a device containing 500 mcg (Anapen®) should be used. However, if only an EpiPen® Jr (150 mcg) is available, this should be used rather than not using one at all. |
Nasal spray device
| In children 4 years and older Weighing 15kg to less than 30 kg | neffy® 1mg |
