Living with it

Travelling with a GLP-1

Most GLP-1 pens are meant to live in a fridge, which makes the first trip feel complicated. It is simpler than it looks: every label says how long the medicine can be kept out of the fridge and at what temperature, and airport security has clear rules for medicines and ice packs.

The short answer

Each GLP-1 label sets how long the medicine may be kept out of the fridge: semaglutide single-dose pens up to 28 days at 8–30°C before the cap is removed, tirzepatide single-dose pens up to 21 days in total at up to 30°C, dulaglutide pens up to 14 days, while semaglutide and orforglipron tablets are stored at room temperature.1234 None may be frozen. In the US, the TSA allows medically necessary liquids above 3.4 oz in carry-on bags, screened separately, and ice or gel packs to keep them cool.56 Keep medicines in your hand luggage, and agree with your prescriber how to handle your dose day across time zones.

What each label allows

Storage out of the fridge, from each medicine's current US prescribing information. None of the injections may be frozen; keep them in the original carton, away from light. Check the leaflet that came with your own medicine.

Two practical consequences: a pen that has been left in a hot car or frozen in a hold should not be used, and a trip shorter than the label's room-temperature allowance may not need cooling at all — check your own product.

Flying

In the United States, the TSA allows medically necessary liquids, medicines and creams in quantities above 3.4 oz (100 ml) in carry-on bags; tell the officer you have them, and they will be screened separately. Injectable medicines and their accessories, including needles, are allowed after screening. Ice packs and gel packs used to keep medicines cool are allowed, including when partly melted.567 Other countries have their own rules — check before you fly.

  • Keep medicines in your hand luggage. Aircraft holds can freeze, and checked bags go missing.
  • Carry the original packaging and a copy of your prescription or a letter from your prescriber, especially abroad.
  • Pack spare needles and a small sharps container.
  • Never share a pen, even with a new needle — the labels warn this can spread blood-borne infections.1

Dose day across time zones

A weekly injection does not have to happen at the same hour, but the labels do set rules for changing the day and for late doses, and they differ between medicines. Before a long trip, ask your prescriber or pharmacist how to handle your dose day, and write the plan down. Cafeity records the dose when you log it, so a changed day shows up in the record rather than disappearing from memory.

Eating while away

Unfamiliar food, bigger portions and more alcohol are the usual travel triggers for nausea, reflux and diarrhoea. Smaller, plainer meals and plenty of fluids help — see eating out and hydration.

Keeping a record of it

Cafeity keeps the dose, the site and any change of dose day on one record, wherever you are, and works offline.

Cafeity dose screen: an estimated medication-level curve labelled "Estimate based on published half-life. Not a measurement", the last dose, the injection site (stomach, lower left), a countdown to the next scheduled dose and a side-effect check-in.
The dose record travels with you.
Cafeity shot-day checklist on the Today screen: protein before your dose, water through the day, take your pen out of the fridge, log your dose, and something to eat after — each with a time you set.
A shot-day routine you set.

Common questions

Can I take GLP-1 pens on a plane?
In the US, yes: medically necessary liquids and injectable medicines are allowed in carry-on bags after screening, and ice packs to keep them cool are allowed.56
How long can a GLP-1 pen stay out of the fridge?
It depends on the product: up to 28 days for semaglutide single-dose pens before the cap is removed, up to 21 days for tirzepatide single-dose pens, up to 14 days for dulaglutide.123
What if my pen freezes?
Do not use it. The labels say not to use these medicines if they have been frozen.21
