Travel & storage rules, drug by drug
Every GLP-1 injectable ships refrigerated, but each one has an official room-temperature window — long enough for most trips, if you know your drug's number. Here they are, from the prescribing information, plus what TSA actually allows at the checkpoint.
Verified Aug 11, 2026Quick answer: keep pens in your carry-on, declare them at security, and know your drug's room-temperature limit — from 21 days (Mounjaro, Zepbound) to 56 days (Ozempic). Refrigeration at 36–46°F is the default; freezing ruins the medication permanently.
How long can it stay out of the fridge?
From each medication's FDA prescribing information. Before first use, all of these stay refrigerated at 36–46°F (2–8°C). Never use a pen that has been frozen — even if it has thawed.

| Wegovysemaglutide | 28 days | Single-dose pen: may be kept at 46–86°F for up to 28 days before use.Source: Wegovy prescribing information (PDF) |
| Mounjarotirzepatide | 21 days | May be stored at room temperature up to 86°F for a total of 21 days.Source: Mounjaro prescribing information |
| Zepboundtirzepatide | 21 days | May be stored at room temperature up to 86°F for a total of 21 days.Source: Zepbound prescribing information |
The windows differ because they're set per-product in each label — count from the day the pen leaves the fridge, and if a pen exceeds its window, the labels say to discard it.
Flying with your medication: the TSA rules
These come from TSA's own "What can I bring?" pages — not airline folklore. Final decisions always rest with the officer at the checkpoint, so declare early and travel with the prescription label visible.
Your medication is exempt from the liquids rule
TSA allows medically necessary liquids in quantities larger than 3.4 oz in your carry-on. You don't have to fit them in the quart-size bag — but you do need to declare them to the officer at the start of screening and remove them from your bag for inspection.
Pens and unused needles are allowed in carry-on
Unused syringes and injection pens are permitted in carry-on bags when they accompany injectable medication. Declare them at the checkpoint. Used needles need a hard-sided sharps disposal container to travel.
Ice packs for medication are allowed, even partially melted
Ordinary frozen gel packs must be solid at screening — but medically necessary gel ice packs used to cool medication are allowed in reasonable quantities regardless of their state. Tell the officer the pack is for medication.
Keep it in your carry-on, not checked baggage
TSA permits medication in checked bags, but carry-on is the safer choice for injectables: the cabin protects it from cargo-hold temperature swings, and it stays with you if a bag is delayed or lost. The American Diabetes Association gives the same advice for insulin, which shares these storage constraints.
This page summarizes official storage labeling and TSA screening rules. It is not medical advice — if a pen has been exposed to heat, cold, or time beyond its window, ask your pharmacist before using it.
