Ask the allergist – June 2024

June 14, 2024

Ask the allergist is a regular feature in our newsletters where Canadian allergists answer your questions! 

Please note: The allergists featured in this series answer questions on general topics, please talk to your doctor if you have questions about your own health or the health of your child. 

This month, we asked Dr. Julia Upton about epinephrine auto-injectors and expiry dates.


Is it OK to use an expired epinephrine auto-injector to treat anaphylaxis?

It’s best to use an in-date epinephrine auto-injector, as an expired device may have less active medication and be less effective than an unexpired one.

With the EpiPen® and ALLERJECT®, there is also a viewing window on the device to be able to see the medication, and it should show a clear liquid. If the liquid is dark, cloudy, discoloured (brown or pink), or looks like it has particles, the device needs to be replaced.

Ideally, try to replace auto-injectors by the expiry date. However, if someone is experiencing anaphylaxis, an expired epinephrine auto-injector is better than no epinephrine auto-injector at all.


Thank you Dr. Upton for your insight! Check out our handy epinephrine sheet for more info and tips!
