GLP-1 guide
Storage and travel: keep the label, keep the temperature.
Most injectable GLP-1s need refrigeration before first use. After that, the room-temperature limit depends on the product and device. This guide summarizes the labels and gives you a practical travel checklist — without guessing.
Cold chain, not guesswork.
The two rules that matter most: do not freeze it, and do not leave it in a hot car. Everything else depends on your product, device, and label.
Quick answer
Refrigerate first. Watch the room-temperature clock.
A short answer, before the product table.
Before first use, most injectable GLP-1s should be refrigerated at 2–8°C (36–46°F). After first use, some products can stay at room temperature for a limited time; others have shorter limits or must stay cold. Never freeze a GLP-1, and do not use one that has been frozen.
For travel, keep the pen in its original carton with the prescription label, carry it in your carry-on, and use a cooler bag with an ice pack — not direct ice. If you are unsure whether the temperature stayed in range, contact your pharmacy or the manufacturer before using it.

Summarized from FDA prescribing information via DailyMed, accessed November 9, 2026. Labels change; use the instructions that come with your product. Oral products — Rybelsus, the Ozempic tablet, the Wegovy tablet, and Foundayo — have different storage instructions; follow their labels.
Keep it cold before first use.
Refrigerate at 2–8°C (36–46°F). Keep it in the original carton, away from the freezer compartment or cooling element.
Track the room-temperature days.
Once you start using a pen, note the date. The allowed time at room temperature is product-specific and does not reset.
Freeze it or cook it.
Do not freeze, and do not leave it in a hot car. Do not use a pen that has been frozen or exposed to excessive heat.
Travel
Keep it with you, not in the hold.
A simple packing routine reduces the two biggest risks: freezing and losing the pen.
- Keep the pen in its original carton with the prescription label.
- Carry it in your carry-on, not checked luggage.
- Use a cooler bag with an ice pack; do not place the pen directly on ice.
- Do not freeze the pen or put it next to a freezer element.
- Allow extra time at security; medication is allowed in carry-on.
- Check the temperature when you arrive; if it was frozen or overheated, do not use it.
The short list.
- Original carton and prescription label.
- Cooler bag and ice pack.
- Alcohol swabs and new needles, if your device needs them.
- Sharps container or travel sharps case.
- Enough supply for the trip, plus a buffer if your prescriber and pharmacy allow.
- Pharmacy and prescriber contact information.
Temperature questions
What to do when the cold chain breaks.
When in doubt, do not use it. Ask the pharmacy or manufacturer.
It was left in a hot car.
Excessive heat can reduce potency. Do not use a pen that has been exposed to high heat. Contact your pharmacy or the manufacturer for guidance.
It froze.
Do not use a product that has been frozen. This is consistent across the labels summarized here. Replace it rather than guessing.
The power went out.
Check how long the refrigerator was out of range and the product’s storage instructions. If you are unsure, do not use it; call your pharmacy.
It looks cloudy or discolored.
For products that should be clear, cloudiness, particles, or discoloration can be a sign of a problem. Do not use it; contact your pharmacist.
Record it
A storage note is part of the record.
If temperature exposure is ever questioned, a simple note helps.
- Date the pen was started.
- Room-temperature days used.
- Travel dates and how the pen was carried.
- Any temperature exposure or damage.
- Supply and refill dates.
Supply with context.
The GLP-1 tracker keeps supply and use-by dates, doses, and notes in one place. It does not monitor temperature or replace the label.
Limits
What this guide does not do.
A short list, so the scope is clear.
- It does not replace the storage instructions that come with your product.
- It does not cover every device, vial, or regional label.
- It does not tell you whether a specific pen is still safe to use.
- It does not provide travel insurance, customs, or airline advice.
