Adrenaline injectors Anapen® and EpiPen® both have windows on the devices to check to see what the fluid (adrenaline) inside the injector looks like.
The adrenaline nasal device neffy® does not have a window to check colour of the fluid.
Check the colour of the fluid in the adrenaline injector when it is not an emergency, for example, check the fluid when you check the device expiry. A&AA recommends you routinely check your device to make sure it is still clear and not discoloured and has not expired.
Adrenaline injectors with discoloured adrenaline or expired adrenaline devices do not work as well and should not be relied on to treat anaphylaxis. However, the most recently expired adrenaline device available should be used if there is no in-date device available.
