How to store and travel with GLP-1 pens

Blog · Updated September 26, 2026 · By the team building Embera

Short answer

All four are stored in the fridge (36 to 46°F) and must never be frozen. Out of the fridge, the labels allow limited time: Wegovy pens up to 28 days at 46 to 86°F before the cap is removed, Ozempic pens 56 days after first use at 59 to 86°F or in the fridge, and Zepbound and Mounjaro pens up to 21 days at up to 86°F. When flying, keep them in your carry-on, never in checked bags.

GLP-1 pens are sensitive to temperature. Here are the storage rules from the labels, and how to handle trips.

Storage at home

Pen Before use Out of the fridge
Wegovy Fridge, 36 to 46°F Up to 28 days at 46 to 86°F, before removing the cap
Ozempic Fridge, 36 to 46°F After first use: 56 days at 59 to 86°F, or in the fridge
Zepbound Fridge, 36 to 46°F Up to 21 days at up to 86°F
Mounjaro Fridge, 36 to 46°F Up to 21 days at up to 86°F

For all of them: do not freeze, and do not use a pen that has been frozen. Keep pens in their carton or with the cap on to protect them from light. Always check the leaflet for your exact product, as details can differ between presentations.

Travel basics

Flying

TSA allows medically necessary liquids and cooling packs for medication in carry-on bags. Tell the officer at screening. For international trips, check the rules of the country you are visiting, and time zones if you want to keep your shot day. Changing your shot day has its own rules: see the best day for your GLP-1 shot.

Questions

Can GLP-1 pens go in checked luggage?

Keep them in your carry-on. The cargo hold can get very cold, and a frozen pen should not be used according to the labels. Your bag could also be delayed.

What if my pen froze or got too hot?

The labels say not to use a pen that has been frozen. If a pen may have been outside its temperature range, ask your pharmacist before using it.

Can I bring ice packs through airport security?

TSA allows medically necessary items like cooling packs for medication in carry-on bags. Tell the officer at screening. Rules can change, so check tsa.gov before you fly.
