GlidedoseTravelling with GLP-1 pens: flights, heat, cold and fridge days
Short answer: carry GLP-1 pens in your carry-on, declare them at security, keep them at or below 30°C (86°F) and never let them freeze. The part that changes by product is how long a pen can go without a fridge. An in-use Ozempic or Wegovy FlexTouch pen is fine at room temperature for the rest of its 56 days (8 weeks in Canada), but a spare unused Ozempic, Wegovy FlexTouch or Saxenda pen has no room-temperature allowance on its label and needs a cooler. Below: a trip-length table for all eight GLP-1s, TSA and CATSA rules, hot-car and freeze wording quoted from the US labels and Canadian monographs, Rybelsus tablets, time zones and what to log in a GLP-1 tracker.

What the labels say that matters on a trip
- Refrigerated range: 2°C to 8°C (36°F to 46°F) for every unused GLP-1 pen, in both countries.
- Ceiling: 30°C (86°F). No US label or Canadian monograph allows room-temperature storage above it.
- Never frozen: every pen label says do not freeze and do not use the medicine if it has been frozen.
- Light: keep single-dose pens and KwikPens in the original carton; keep the cap on Ozempic, Wegovy FlexTouch, Victoza and Saxenda pens. The Victoza and Saxenda US labels add "protect from excessive heat and sunlight."
- Car warning: the US Instructions for Use for Ozempic, Wegovy and Saxenda say: "Do not leave it in a car or other place where it can get too hot or too cold."
- No needle attached: the Novo Nordisk multi-dose pen labels say to remove the needle after each injection and store the pen without one, to reduce contamination, infection and leakage.
Spare pens: how long each can go without a fridge
For an unused pen, this is the label allowance at room temperature, not above 30°C (86°F). "Not listed" means the label gives no room-temperature allowance before first use, so the pen should stay at 2°C to 8°C until you start it.
| Product | Unused, US label | Unused, Canada monograph | After first use | Travel-relevant wording |
|---|---|---|---|---|
| Ozempic pen (multi-dose) | Not listed (keep cold) | Not listed (keep cold) | 56 days (US) / 8 weeks (Canada) | Keep the pen cap on; "Do not leave it in a car or other place where it can get too hot or too cold" (US Instructions for Use) |
| Ozempic single-dose prefilled syringe (US) | 28 days | Not sold in Canada | One dose | If needed, 8–30°C (46–86°F) up to 28 days |
| Wegovy single-dose pen | 28 days | 28 days | One dose | Before the cap is removed, in the carton; throw away if exposed to light or above 30°C (86°F) |
| Wegovy FlexTouch (multi-dose) | Not listed (keep cold) | Not listed (keep cold) | 56 days (US) / up to 8 weeks (Canada) | Throw away if exposed to light or above 30°C (86°F) (US Medication Guide) |
| Mounjaro or Zepbound single-dose pen or vial | 21 days | 21 days | One dose | Running total of 21 days; Canada: Mounjaro single-dose only |
| Mounjaro or Zepbound KwikPen (4 doses) | 30 days | 30 days | 30 days after first use or 4 doses, whichever first | Also discarded after a total of 30 days at room temperature |
| Trulicity single-dose pen | 14 days | 14 days | One dose | Running total of 14 days; glass parts, do not use if dropped on a hard surface |
| Victoza pen (daily) | 30 days | Not listed (keep cold) | 30 days (Canada patient info: 1 month) | US: a pen left out "by mistake" before first use must be used or thrown away within 30 days; throw away if above 30°C (86°F) |
| Saxenda pen (daily) | Not listed (keep cold) | Not listed (keep cold) | 30 days (Canada patient info: 1 month) | "Do not leave it in a car or other place where it can get too hot or too cold" (US Instructions for Use) |
Two Canada vs US differences matter for travellers. The Victoza "left out by mistake" 30-day allowance is in the US patient instructions; the Canadian monograph storage wording counts its 30 days from initial use, so treat a spare Canadian Victoza pen as fridge-only. And the Ozempic single-dose prefilled syringe is listed on the US label only; the Canadian Ozempic monograph covers the multi-dose pen. Zepbound in Canada is the KwikPen, so the 30-day rule applies.
Trip-length table: can a spare unused pen stay out the whole trip?
"Yes" means the label's room-temperature allowance (not above 30°C / 86°F) covers the full trip if the pen has not been out of the fridge before. "Cooler" means plan for 2°C to 8°C storage for at least part of the trip. Running-total pens (Mounjaro/Zepbound single-dose, Trulicity) lose any days they already spent out.
United States labels

| Saxenda pen (daily) | cooler | cooler | cooler | cooler | cooler | cooler | cooler |
* The US Victoza 30-day allowance for an unused pen is for one left out of the fridge by mistake, not a planned travel allowance, so spare Victoza pens are shown as cooler.
Canadian product monographs
| Unused pen | 3 days | 7 days | 10 days | 14 days | 21 days | 28 days | 30 days |
|---|---|---|---|---|---|---|---|
| Ozempic pen (multi-dose) | cooler | cooler | cooler | cooler | cooler | cooler | cooler |
| Wegovy single-dose pen | yes | yes | yes | yes | yes | yes | cooler |
| Wegovy FlexTouch (multi-dose) | cooler | cooler | cooler | cooler | cooler | cooler | cooler |

| Victoza pen (daily) | cooler | cooler | cooler | cooler | cooler | cooler | cooler |
| Saxenda pen (daily) | cooler | cooler | cooler | cooler | cooler | cooler | cooler |
The in-use pen you are already injecting from is usually easier: Ozempic and Wegovy FlexTouch can stay out of the fridge for the rest of their 56-day (8-week) window, Victoza and Saxenda for the rest of 30 days, and an opened KwikPen until 30 days after first use or its 4th dose. Use the out-of-fridge date calculator for exact dates and the pen end-date calculator for in-use pens.
Airport security: TSA and CATSA
| Rule | TSA (US) | CATSA (Canada) |
|---|---|---|
| Liquid medication over 100 mL / 3.4 oz | Allowed in reasonable quantities for your trip; declare it at the checkpoint | Allowed in carry-on; does not have to go in the 1 L bag; present it to the screening officer |
| Carry-on or checked | Both allowed | Recommends all medication in carry-on, easy to reach |
| Ice and gel packs | Medically necessary gel ice packs allowed in reasonable quantities whether frozen, melted or slushy; tell the officer | Exempt when used to refrigerate medicine; use gel packs or non-electric insulated containers and declare them |
| Electric or battery coolers | Not addressed on the medication pages | Place in checked luggage; may get extra screening |
| Pen needles and syringes | Allowed with the medication; declare them | Allowed when you have the medication with you; needle guard in place |
| Labels and paperwork | Labelling recommended, not required | Original container with pharmacy label recommended; documentation not required |
| Help in advance | TSA Cares | Contact CATSA at least 48 hours before the flight; Family and Accessible Line |
CATSA also suggests telling your airline about medication that needs special handling or in-flight refrigeration when booking or at check-in. Customs and import rules at your destination are separate from airport security; check them before international travel.
Packing checklist
- The in-use pen in its cap or carton, in your carry-on, plus enough new pen needles for the trip if your pen uses them (Ozempic, Wegovy FlexTouch, Victoza and Saxenda labels say to use a new needle for each injection). Single-dose pens have the needle built in.
- Spare unused pens that the table above marks "cooler", in an insulated case with gel packs and a barrier so they don't touch the pack.
- Original packaging and pharmacy label, as CATSA recommends; a copy of your prescription is useful if a pen is lost or damaged away from home.
- A small sharps container or a sturdy travel sharps case for used needles.
- Rybelsus tablets in the original bottle (US) or blister card (Canada).
Heat, hot cars and beach days
Every label stops at 30°C (86°F). On a trip that limit is easy to pass in a parked car, a sunny windowsill, a beach bag or a hotel room with the air conditioning off. The label wording:
| Product | Heat wording (US label or Instructions for Use) |
|---|---|
| Ozempic | Protect from excessive heat and sunlight; do not leave the pen in a car or other place where it can get too hot or too cold |
| Wegovy | Throw away the single-dose pen or FlexTouch if exposed to light or temperatures above 86°F (30°C); do not leave it in a car |
| Mounjaro, Zepbound | Room temperature only up to 86°F (30°C); store in the original carton to protect from light |
| Trulicity | Room temperature below 86°F (30°C) for a total of 14 days; protect from direct heat and light |
| Victoza | Protect from heat and sunlight; throw away if exposed to temperatures above 86°F (30°C) |
| Saxenda | Protect from excessive heat and sunlight; do not leave the pen in a car or other place where it can get too hot or too cold |
The Canadian monographs use the same ceiling, "below 30°C" or "not above 30°C", and the same "protect from excessive heat and light" wording for the Novo Nordisk pens. See Canada heat, freeze and light for the monograph-by-monograph table. If a pen may have overheated, ask a pharmacist before you use it; on a trip, a local pharmacy can help.
Freezing: ice packs, hotel fridges and winter cars
A frozen pen cannot be used, on any label. On a trip the common causes are a pen resting directly on a frozen gel pack, the back of a small hotel or rental fridge near the cooling element (Ozempic, Wegovy, Victoza and Saxenda labels warn against storing next to it), and a car left overnight in a Canadian or northern US winter. Use a barrier against gel packs, keep pens in the main compartment of a fridge rather than against the back wall, and bring them inside with you in winter.
Rybelsus and other oral semaglutide on a trip
Tablets don't need a cooler, but moisture is the label's concern. The US label: store at 20°C to 25°C (68°F to 77°F), excursions 15°C to 30°C (59°F to 86°F) permitted, in a dry place, in the original bottle until use. The Canadian Rybelsus monograph: room temperature, 15°C to 30°C, in the original blister packaging to protect from moisture and light, and take each tablet directly after removing it from the blister. That points against a weekly pill organizer or a steamy bathroom shelf. CATSA has no volume limit for solid tablets. For the water and 30-minute wait rules, see how to take oral semaglutide.
Time zones and your weekly injection day
None of the labels has a travel or time-zone rule. What they do set is a minimum gap between doses if the day changes, which is useful to know before a long-haul trip. This is the label wording, not advice on what to do; ask your pharmacist or prescriber before travel.
| Product | Minimum gap when changing the weekly day |
|---|---|
| Ozempic | At least 2 days (48 hours), US and Canada |
| Wegovy injection | 2 days (US); at least 3 days / 72 hours (Canadian monograph) |
| Mounjaro, Zepbound | At least 3 days (72 hours) |
| Trulicity | Last dose at least 3 days (72 hours) before the new day |
| Victoza, Saxenda, Rybelsus | Daily products; see the missed-dose guide for what the labels say about a missed daily dose |
If a dose ends up late because of travel, the missed-dose guide has each label's window and a date calculator.
What to log in a GLP-1 tracker while travelling
Label limits are all dates and temperatures, so a log is the simplest way to stay inside them away from home. A GLP-1 tracker such as Glidedose can help you keep:
- The date each spare pen left the fridge, and running days out for Mounjaro/Zepbound single-dose and Trulicity pens.
- The first-use date of the pen you are travelling with, so its 30-day, 56-day or 8-week end date is visible.
- Each injection with the local time and time zone, and the injection site.
- Any heat or freeze scare (a hot car, a pen against an ice pack), so you can ask a pharmacist before the next injection.
- Side effects on the trip, which can help at your next appointment (see tracking GLP-1 side effects).
Glidedose is a GLP-1 tracker. It never suggests a dose or a schedule change, and it does not replace the leaflet in your box or your pharmacist.

This page summarizes official product labels and airport security guidance as general information. It is not medical advice. Follow your prescriber's or pharmacist's instructions and the leaflet that came with your medication, and ask a pharmacist if a pen may have been frozen or overheated. Labels and security rules change; check the current versions before you travel.
Frequently asked questions
Can I fly with Ozempic, Wegovy, Mounjaro or Zepbound pens?
Yes. TSA (US) allows medically necessary liquids in reasonable quantities for your trip in carry-on bags, above the usual 3.4 oz (100 mL) limit, as long as you declare them at the checkpoint. CATSA (Canada) allows prescription liquid medication over 100 mL in carry-on, outside the 1 L bag, and asks you to present it to the screening officer. Both agencies allow pen needles and syringes when you carry the medication that needs them.
Should GLP-1 pens go in checked luggage?
TSA permits liquid medication in checked bags, but CATSA recommends packing all medication in your carry-on, in an easy-to-reach place. Carry-on keeps pens with you, where you can see the temperature, and protects against lost bags. Every GLP-1 pen label says do not use it if it has been frozen, and the room-temperature limit on every label is 30°C (86°F).
Do I need a cooler to travel with my GLP-1 pen?
It depends on the pen and the trip length. Unused Ozempic pens, Wegovy FlexTouch and Saxenda pens have no room-temperature allowance before first use on their labels, so spare pens need to stay at 2°C to 8°C (36°F to 46°F). An in-use Ozempic or Wegovy FlexTouch pen can stay at room temperature (up to 30°C / 86°F) for the rest of its 56 days (US) or 8 weeks (Canada). Mounjaro and Zepbound single-dose pens allow a running total of 21 days unrefrigerated, KwikPens 30 days, and Trulicity 14 days.
Are ice packs allowed through airport security for medication?
Yes. TSA says medically necessary gel ice packs in reasonable quantities are allowed regardless of whether they are frozen, melted or slushy; tell the officer at the checkpoint. Ordinary frozen items must be frozen solid. CATSA exempts ice or gel packs used to refrigerate medicine and suggests cooling gel packs or non-electric insulated containers; battery-operated or electric coolers should go in checked luggage.
Can my pen touch the ice pack?
Keep a layer between them. Every GLP-1 pen label says not to freeze the medicine and not to use it if it has been frozen, and the Novo Nordisk labels (Ozempic, Wegovy, Victoza, Saxenda) also say not to store pens directly next to the fridge cooling element. A cloth, the carton or a divider stops the pen freezing against a frozen pack.
I left my pen in a hot car. Can I use it?
The labels say no room-temperature storage above 30°C (86°F). The Wegovy US Medication Guide says to throw the pen away if it has been exposed to temperatures above 86°F (30°C), and the Victoza US instructions say the same. The Ozempic, Wegovy and Saxenda US instructions say not to leave the pen in a car or other place where it can get too hot or too cold. Ask your pharmacist before using a pen that may have overheated.
Does a trip reset the out-of-fridge days?
No. Mounjaro and Zepbound single-dose pens (21 days) and Trulicity pens (14 days) use a running total, so days out of the fridge on a trip add to any earlier days out. In-use windows for Ozempic, Wegovy FlexTouch, Victoza, Saxenda and the KwikPen count from first use, wherever the pen is stored.
How do I travel with Rybelsus tablets?
Rybelsus is not refrigerated. The US label says to store tablets at 20°C to 25°C (68°F to 77°F), with excursions to 15°C to 30°C (59°F to 86°F), in a dry place, in the original bottle until use. The Canadian monograph says room temperature (15°C to 30°C) in the original blister packaging to protect from moisture and light. Solid tablets have no CATSA volume limit, but keep them in their original pack rather than a pill organizer.
What about my weekly injection day when I cross time zones?
The labels do not have a time-zone rule, but they do set a minimum gap if you move your weekly day: Ozempic at least 2 days (48 hours); Mounjaro, Zepbound and Trulicity at least 3 days (72 hours); Wegovy 2 days on the US label and at least 3 days (72 hours) in the Canadian monograph. Ask your pharmacist or prescriber how to time doses on a long trip before you go. Glidedose never suggests a dose or a schedule change.
What should I log in a GLP-1 tracker while travelling?
The date each pen left the fridge and the date of first use, running days unrefrigerated for single-dose pens, any heat or freeze scare, the time and time zone of each injection, and which injection site you used. Glidedose is a GLP-1 tracker for those dates and events; it does not tell you what dose to take.
