How to store and travel with GLP-1 pens

✓Last reviewed October 20, 2026 · Written by Dr. George Grunberger · Medical review: pending — clinician review in progress · How we review

Short answer

Keep unopened pens refrigerated (36–46°F / 2–8°C), never frozen. In use, most pens tolerate room temperature for a limited time (Ozempic up to 56 days; Wegovy up to 28 days; Zepbound and Mounjaro up to 21 days). Carry them in hand luggage with the prescription label.
