Traveling With a GLP-1 Pen: TSA Rules, Storage and Packing

You can travel with a GLP-1 pen. Two sets of rules matter: the TSA's rules for getting through security, and the storage instructions printed in your pen's own paperwork. This guide puts both in one place and ends with a packing checklist.

Can you bring a GLP-1 pen through airport security?

Yes. On its page for liquid medications, the TSA says it allows “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip,” in both carry-on and checked bags. The usual carry-on limit is 3.4 ounces (100 milliliters) per container in a quart-size bag, and the TSA lists medications as an exemption. The one condition: you must declare them to TSA officers at the checkpoint for inspection.

Needles follow the same logic. The TSA says unused syringes are allowed when accompanied by injectable medication, and that you must declare them too. It recommends, but does not require, that your medication be labeled.

At the checkpoint, the TSA's page on disabilities and medical conditions asks you to:

• Take medically necessary items out of your carry-on and place them in a bin.
• Tell the officer what they are. You can say it out loud, show a TSA Notification Card, or show medical documentation.
• Tell the officer if you do not want your liquid medication to be X-rayed or opened.

If you want extra help, you can ask TSA Cares for a Passenger Support Specialist, a TSA officer with specialized training. The TSA asks you to reach out at least 72 hours before departure, through its online form or at (855) 787-2227 (8 a.m. to 11 p.m. ET on weekdays, 9 a.m. to 8 p.m. ET on weekends and holidays). That support does not exempt you from screening, and the TSA says the final decision on any item rests with the officer.

Can you bring ice packs to keep your pen cool?

Yes, and the medical rule is more relaxed than the everyday one. For ordinary freezer packs, the TSA says they must be frozen solid at screening, and partly melted or slushy packs fall under the liquids limit. For medical needs, the TSA's disabilities page says ice packs, freezer packs and gel packs used to keep medically necessary items cool “may be presented at the screening checkpoint in a frozen, partially frozen or melted state.” Its gel ice pack page adds that medically necessary gel packs in reasonable quantities are allowed whatever their state, as long as you tell the officer.

An insulated travel case with a cold pack is the simplest setup. Look for one that holds your pens in their original carton, closes fully and fits in the bag you keep at your seat. The Next Size Club accessories shop carries a pen travel case if you need one.

One caution. Every label in the table below says not to use a pen that has been frozen, and Novo Nordisk's labels say not to store pens directly next to a refrigerator's cooling element. So don't let a frozen pack press straight against the pen. If you're unsure how to pack yours, ask your pharmacist.

Should your pen go in your carry-on or your checked bag?

The TSA allows both, but your carry-on is the safer place. The CDC's guide to traveling with medicine says to “pack medications in a carry on in case your luggage is lost or delayed.” Eli Lilly's travel FAQ for the Zepbound KwikPen, written for Canada, goes further: it says not to pack the pen in checked luggage, because luggage holds can have wide temperature swings that may be too cold or too hot for it.

For trips abroad, the CDC also recommends that you:

• Keep medicines in their original, labeled containers.
• Bring enough for the whole trip, plus extra in case of travel delays.
• Carry copies of your prescriptions, and ask your provider for a note if you use an injectable medicine.
• Contact the embassy of your destination, and of any country where you have a layover, to make sure your medicines are allowed.

The CDC adds that extreme temperatures can reduce the effectiveness of many medicines. That is where your pen's label comes in.

How long can a GLP-1 pen stay out of the fridge?

It depends on the product and on the type of pen, and the numbers are not the same. Here is what each manufacturer's current US prescribing information says. Use it to plan, then follow the instructions that came with your own pen, because pen types and labels get updated.

A few rules repeat across these labels:

• Never freeze it. All four labels say not to use a pen that has been frozen.
• Keep it away from heat and light. Lilly's labels say to keep pens in the original carton to protect them from light. Novo Nordisk's labels say to protect pens from excessive heat and light.
• Keep the cap on and the needle off. The Ozempic and Wegovy FlexTouch instructions say to keep the pen cap on when not in use and to remove the needle after each injection.
• Write the date down. The Ozempic instructions suggest writing the disposal date on your calendar, and the Wegovy prefilled syringe instructions say to record the date it left the fridge. Doing the same for any pen keeps the countdown simple.

Don't leave a pen anywhere that could get hotter than 86°F (30°C), like a parked car or a sunny windowsill. If a pen froze, got too hot or ran past its time limit, the labels say not to use it. Call your pharmacist or prescriber to ask what to do next.

What if your trip crosses time zones?

Ask your prescriber how to handle dose timing, before you leave. Bring your travel dates to that conversation and write the answer down so it travels with your pens. This guide does not give timing advice, because the right answer depends on your medication and your treatment plan.

How do you get rid of used needles and pens while traveling?

Plan this before you go. The FDA says to place needles and other sharps in a sharps disposal container immediately after use, and to “always carry a small, travel-size sharps disposal container in case other options are not available.”

• What goes in it. The Wegovy instructions say to put a used single-dose pen in an FDA-cleared sharps disposal container right away, not in household trash. For pens that take a new needle each time, like Ozempic, the label says to remove and safely discard the needle after each injection.
• Flying home with it. The TSA allows used syringes in carry-on and checked bags when they are in a sharps disposal container or a similar hard-surface container.
• No container with you? The Wegovy instructions allow a household container that is made of heavy-duty plastic, closes with a tight-fitting, puncture-resistant lid, stays upright and stable, resists leaks, and is labeled to warn of hazardous waste. The FDA gives a laundry detergent container as an example.
• Never loose. The FDA says never to put loose needles in household or public trash cans or recycling bins, and never to flush them down the toilet.
• When it is about three-quarters full, the FDA says to follow your community's guidelines for disposal. Rules vary by state, and Safe Needle Disposal (1-800-643-1643), listed by the FDA, can tell you what applies where you are.

Your GLP-1 travel packing checklist

• Pens for the whole trip, plus extra in case of delays.
• Pens in their original carton, with the pharmacy label.
• New pen needles, if your pen uses them.
• An insulated case and ice or gel packs, with a layer between the pack and the pen.
• A travel-size sharps disposal container.
• Copies of your prescriptions and, for trips abroad, a note from your provider.
• The instructions that came with your pen, or a photo of the storage section.
• Your prescriber's answer on dose timing, written down.
• The date each pen came out of the fridge.
• The TSA Cares number, (855) 787-2227, if you want help at security.
• An empty water bottle to fill after security. Our guide to staying hydrated on a GLP-1 has simple habits for travel days.
• Comfortable layers that fit you now. See what to wear while you're losing weight fast.

Pack the pens last so they come out first. At security, put them in a bin and tell the officer what they are.
