Anaphylaxis · Expiration and storage
An EpiPen or epinephrine auto-injector typically lasts about 12 to 18 months from when it is dispensed. The exact expiration date is printed on the device and the box, so check it when you pick it up and set a reminder to replace it before then.
| Question | Answer |
|---|---|
| Typical shelf life | About 12 to 18 months from dispensing |
| Where to find the date | Printed on the device and the carton |
| Storage | Room temperature, away from heat and cold |
| Check the window | Liquid should be clear and colorless |
| Expired and no other option in an emergency | Better than nothing, then call 911, but replace promptly |
Always replace an expired device. But if you are ever in a true emergency with only an expired auto-injector on hand, using it is better than using nothing: epinephrine slowly loses potency past its date but does not become harmful. Use it, then call 911. The point is not to rely on this, replace expired devices so you are never in that position.
If yours is expiring, Bidwell Health can prescribe a replacement online for adults with a known severe allergy or a prior prescription, when clinically appropriate.
Tip: neffy, the needle-free epinephrine nasal spray, is more heat-stable and has a longer shelf life than auto-injectors, which some travelers prefer. See EpiPen vs. neffy.

You should always replace an expired auto-injector. But in a true emergency with no in-date device available, using a recently expired EpiPen is better than using nothing; epinephrine slowly loses potency over time but does not become dangerous. Then call 911. Replace expired devices promptly so you are not relying on this.
Store it at room temperature, away from heat and cold. Do not leave it in a hot car or checked luggage, and do not refrigerate or freeze it. Check the viewing window: the liquid should be clear and colorless. If it looks cloudy, discolored, or has particles, replace it.
If you have a known severe allergy or a prior prescription, Bidwell Health can prescribe a replacement online in a $45 visit, no video, sent to your pharmacy when clinically appropriate. Generic auto-injectors are usually the lowest-cost option.
