Do You Keep Wegovy in the Fridge?

Wegovy (semaglutide) is a prescription-only, once-weekly injectable medicine that requires careful storage to stay effective. Here is what is generally recommended — always cross-check with your own patient information leaflet, as the authoritative source for your specific pen:

• In the fridge: Store unused Wegovy pens in a refrigerator, typically between 2°C and 8°C. Keep them away from the freezer compartment and away from the back wall of the fridge, where temperatures can drop below freezing.
• At room temperature: If you need to carry a pen with you or cannot access a fridge, Wegovy can generally be kept at room temperature (below around 30°C) for a period — check your leaflet for the specific number of days this applies to, as it can vary.
• Protect from light: Keep pens in their original packaging until use, as this helps shield them from light.
• Never freeze: A pen that has been frozen should not be used. Freezing can damage the medicine.

If you are ever unsure whether a pen has been stored correctly, contact your prescriber or pharmacist before using it — do not assume it is still effective.

For more detail on whether refrigeration is strictly required day-to-day, the page on whether you need to keep Wegovy in the fridge covers this in more depth. You may also find it helpful to read about whether you have to keep Wegovy refrigerated and what flexibility exists. If you are on Mounjaro and want to know about putting a pen back in the fridge, storage guidance for Mounjaro pens is also available.

Keeping track of which pen you are using, when you opened it, and when your next dose is due is easier when it is all in one place. GLP Trackr's dose logging feature lets you record each injection — the date, time, and dose strength — so you always have a clear record of where you are in your weekly schedule. This is especially useful if you have ever second-guessed whether you took your dose, or if you are trying to work out how long a pen has been out of the fridge.

The app's dose reminder feature means you get a gentle nudge before your next injection is due, helping you plan ahead — including making sure your pen is ready and stored correctly before the day arrives.

If you ever have concerns about a pen that may not have been stored properly, log a note in the app and bring it to your next conversation with your prescriber. GLP Trackr is a companion for your journey — it is not a substitute for advice from your healthcare professional, and any questions about whether a pen is still safe to use should go to them or your pharmacist.

You can also explore broader guidance and tracking support on the GLP Trackr medication tracking hub.
