But, in the event ofanaphylaxis, an expired EpiPen is probably better than no EpiPen at all.
An EpiPen is an auto-injecting gear that delivers epinephrine to treat severe allergic reactions, including anaphylaxis.
Epinephrine, also known asadrenaline, is both a neurotransmitter and a hormone.

It’s also the medication inside of an EpiPen.
EpiPens begin to work immediately after they are injected.
Epinephrine degrades relatively quickly, particularly when exposed to light, air, or extreme temperatures.
How to Read Expiration Dates
An EpiPen expiration date can be found on the auto-injector’s label.
It is expressed as a set of letters and a number, signifying a month and year.
EpiPens always expire on the last day of the month listed.
Can I Use an Expired EpiPen?
Without a doubt, it is far better to use an expired EpiPen than none at all.
Does this mean that you should purposefully keep your EpiPens for years after they expire?
Not if you could help it.
Expiration dates aside, it’s important to regularly inspect your EpiPens for signs they have gone bad.
The liquid in an EpiPen should be clear.
Summary
The expiration date for most EpiPens is at least 12 months after its manufacturing date.
