How long is an EpiPen good for?
An EpiPen is good until the expiration date printed on it. Neither of the FDA-approved EpiPen labels states a shelf life counted from manufacture; both simply say to replace the pen before its expiration date.
How much time that leaves you depends on when the pen was made and how long it sat before it reached you, so check the date when a new pen arrives rather than assuming a set number of months. The FDA’s records show the EpiPen’s shelf life was set at 20 months in 2002, down from 27 months, but that is a historical figure: no current FDA document states today’s.
Two things can end a pen’s life before its date. Epinephrine breaks down when it’s exposed to light, air or temperature extremes, so the label says to replace a pen that has been through extreme heat or cold. And the label says to check the liquid regularly: it should be clear and colorless. If it looks pink or brown, is cloudy or has particles in it, replace the pen whatever the date says.
The EpiPen label also suggests talking with a doctor about extra pens for work, school or other places a person spends time, and replacing a used pen so two are always on hand. EpiPen 2-Paks come with a gray trainer that has no medicine, no needle and no expiration date.
How to find an EpiPen’s expiration date
The expiration date is printed on the pen’s label and on the carton. On the redesigned EpiPen in the FDA’s 2026 label, it sits in a black panel on the side of the pen.
The FDA approved a redesigned EpiPen in March 2026, with a twist-off safety cap, an outer carton in place of the carrier tube, and new product codes. Both versions may be in circulation for a while, so learn to read both. A date that shows only a month and year runs through the last day of that month, as the 2019 EpiPen notice posted by the FDA explains.
While you’re looking, check the rest of the pen:
- The liquid: hold the pen against a white background in good light and look through the viewing window. It should be clear and colorless.
- The safety top: on the older version, if the blue safety release is already raised, don’t use the pen and don’t push it back down; replace it. On the 2026 version, check the tamper-evident seal.
- Damage: a pen that has been dropped should be checked for cracks and leaks, and replaced if you find or suspect either.
For a school nurse’s office or a workplace first aid station with several pens, write each pen’s date in your log, or track it so a reminder reaches you before it passes.
Can you use an expired EpiPen?
The FDA’s general advice on expired medicine is not to use it: after the expiration date there’s no guarantee a drug is safe and effective. The EpiPen label says to replace the pen before its date. Neither addresses an emergency where an expired pen is the only one at hand.
The FDA explains that an expiration date marks how long the maker has shown the drug keeps its strength and purity when stored as the label says. After that, a drug may lose strength or break down. For epinephrine, a pink or brown color is a sign of that breakdown.
The FDA has extended EpiPen dates before, but only for specific lots during a shortage. In August 2018, a Mylan and Pfizer notice posted by the FDA extended listed lots of EpiPen 0.3 mg and its generic that were dated April to December 2018. In June 2019, a second notice added four months to every EpiPen 0.3 mg lot then on the market. EpiPen Jr was left out both times. The FDA’s current list of extended dates, checked in September 2026, includes no epinephrine products.
What to do with an expired pen in a real emergency is a question for the prescriber, or for your school or organization’s medical protocol. The practical answer is to never be in that position: replace pens on time, keep a spare, and call 911 for anyone having a severe allergic reaction.
How to store an EpiPen
Store EpiPens at room temperature, 68 to 77°F (20 to 25°C), in their carrier tube or carton. Don’t refrigerate or freeze them, and don’t leave them in a car.
The label allows short trips between 59 and 86°F (15 and 30°C), the kind of exposure a pen gets in a bag on the way to school. It names a car’s glove box and trunk as places not to store it, because they get far hotter and colder than that. If a pen has been through extreme heat or cold, replace it.
Light breaks epinephrine down too. On the older version, the carrier tube is what protects the pen from light, and the label notes the tube isn’t waterproof. The 2026 version comes in an outer carton instead, and the label says to keep the pens in it. The 2026 label also says to keep the trainer somewhere separate from the real pens, so nobody grabs the wrong one in an emergency.
For a school or workplace that stocks pens, pick a spot that stays at room temperature, is easy to reach fast, and is out of direct sunlight. Keeping them beside the AED means one trip for both.
Other epinephrine auto-injectors and nasal sprays
Generic auto-injectors, Auvi-Q and the nasal spray neffy all carry their own expiration dates and storage rules. Most share EpiPen’s room-temperature range; neffy tolerates more heat.
| Product | Form | Store at | Light protection | Worth knowing |
|---|---|---|---|---|
| EpiPen and EpiPen Jr (Viatris) | Auto-injector | 68 to 77°F, trips 59 to 86°F | Carrier tube; outer carton on the 2026 version | Don’t refrigerate or freeze |
| Epinephrine auto-injector (Viatris authorized generic) | Auto-injector | 68 to 77°F, trips 59 to 86°F | Carrier tube | Same application and rules as EpiPen |
| Epinephrine auto-injector (Teva) | Auto-injector | 68 to 77°F, trips 59 to 86°F | The pen body itself | Keep away from water; replace if darker than slightly yellow |
| Epinephrine auto-injector (Amneal) | Auto-injector | 68 to 77°F, trips 59 to 86°F | Carrier tube | The date is on the auto-injector’s own label |
| Auvi-Q | Talking auto-injector | 68 to 77°F, trips 59 to 86°F | Outer case | Still works if the voice fails |
| neffy | Nasal spray | 68 to 77°F; tolerates up to 122°F | Blister or carry case | Freezes below 5°F; usable once thawed |
A few differences matter for storage. Teva’s generic has no carrier tube: the pen body itself shields the drug from light, and its label uses a slightly different color check. neffy, which the FDA approved in August 2024 as the first epinephrine nasal spray for anaphylaxis, handles heat up to 122°F but freezes below 5°F, and won’t spray while frozen. Its label says it can be used once thawed, but not to wait for it to thaw in an emergency.
None of these labels states a shelf life from manufacture. Like EpiPen, each says to replace the product before its printed date.
What to do with an expired EpiPen
Replace it first, then put the expired pen in an FDA-cleared sharps container. An EpiPen holds a needle, so it doesn’t go in the household trash.
The EpiPen label covers expired, unused and used pens the same way: into a sharps container. If you don’t have an FDA-cleared one, the label allows a sturdy household container made of heavy-duty plastic, with a tight-fitting, puncture-resistant lid, that stays upright, doesn’t leak and is labeled as hazardous waste. A pen used in an emergency goes to the person’s health care provider. The 2026 label adds that a pen whose safety cap has been removed must be thrown away, even if it was never used.
The FDA’s sharps guidance, which covers home, work and travel, is two steps: put sharps in the container right away, then dispose of the container the way your community allows once it’s about three-quarters full. Options vary by area, and can include drop boxes at doctors’ offices, hospitals, pharmacies, health departments and police or fire stations, household hazardous waste sites and mail-back programs.
Don’t flush epinephrine: it isn’t on the FDA’s list of medicines that may be flushed.
Tracking EpiPen expiration at schools and workplaces
A school or workplace with stock epinephrine needs to know where every pen is, when each one expires and who checks them. A monthly check and a reminder before each date keeps pens from lapsing unnoticed.
Pens get bought at different times, so their dates never line up, and the person who bought them may have moved on by the time they expire. A simple routine prevents that:
- Keep a list of every pen: product, dose (0.3 mg or 0.15 mg), lot number, expiration date and storage spot.
- Check each pen monthly: date, liquid color, safety top or seal, and whether it’s still where it belongs.
- Order replacements a month or two before the date, so there’s no gap.
- Replace any pen that’s used, damaged or has been somewhere too hot or cold.
AED Log’s EpiPen and epinephrine tracking records each pen’s brand, dosage, lot, expiration date, quantity and storage location, runs the monthly check on any phone, and alerts the people responsible before a pen expires. It’s an add-on at $8 per unit per year, alongside the AEDs most schools already track in it. The same applies to naloxone: see our guide to Narcan expiration.
