Carry-on details
Allowed. Naloxone nasal spray (brand name Narcan) is a medically necessary liquid medication, so it's exempt from the standard 3.4 oz (100 mL) liquids limit and doesn't need to go in your quart-size bag. It is not a controlled substance and TSA does not require a prescription to carry it. Declare it to the TSA officer at the checkpoint for separate screening, and keep it in your carry-on so it's on hand if you or someone nearby needs it during the flight.
Checked-bag details
Allowed without restriction, though carrying naloxone in your carry-on is strongly recommended so it's immediately accessible in an emergency and isn't exposed to cargo-hold temperature extremes.
Special instructions
You do not need a prescription or a doctor's note to carry naloxone. Keeping it in its original packaging can help speed up screening but isn't required.

FAQ
- Is Narcan a controlled substance I need to declare specially?
- No. Naloxone is not a controlled substance and carries no abuse risk under TSA rules — it's treated like any other liquid medication. You still declare it to the TSA officer, the same as other medically necessary liquids over 3.4 oz.
- Do I need a prescription to bring naloxone on a plane?
- No. TSA does not require a prescription or documentation to carry naloxone nasal spray, whether it was obtained over the counter or prescribed.
- Can I bring more than one dose of Narcan?
- Yes. As a medically necessary liquid, naloxone is exempt from the 3.4 oz limit, so you can bring a reasonable quantity for your trip as long as you declare it at the checkpoint.
