Short answer: refrigerate it before first use, and after that most semaglutide pens can spend a limited time at room temperature. The exact in-use window is on your product’s label. Here’s the practical version, including travel and compounded vials. This is educational, not medical advice; the label and your pharmacist are the authority.
Keep it in the refrigerator, about 36–46 F (2–8 C). Don’t freeze it — a semaglutide product that has frozen should be discarded.
Per the labels, an in-use pen can generally be kept refrigerated or at room temperature below about 86 F (30 C) for a limited window — for example, an Ozempic pen is labeled for use within 56 days after first use. Wegovy and other products have their own in-use windows, so check yours. Keep the cap on and protect it from light.
Compounded vials don’t follow the brand labels — storage comes from the compounding pharmacy’s instructions (often refrigerate, protect from light, use within a set window).
Use an insulated bag or a medical cooler for longer trips; avoid heat and freezing. On flights, keep it in your carry-on, not checked luggage (where it can freeze).
It depends on the product. An Ozempic pen is labeled for 56 days after first use (fridge or below 86 F); Wegovy and others have their own windows. Check your label.
No. A semaglutide product that has frozen should be discarded, and it should not be stored in the freezer.
Use an insulated bag or cooler for longer trips, avoid heat and freezing, and keep it in your carry-on on flights.
It varies by product — for example 56 days for Ozempic. Note your first-use date and follow the label.
Yes. Follow the compounding pharmacy’s instructions rather than a brand label.
