How Long Can Wegovy Be Out of the Fridge? Storage and Travel Rules
Proper storage of Wegovy (semaglutide) is critical to maintaining medication effectiveness and safety. While unopened U.S. single-dose pens require standard refrigeration between 36°F and 46°F (2°C to 8°C), official guidelines permit pens to be kept at controlled room temperatures (46°F to 86°F / 8°C to 30°C) for up to 28 days prior to removing the pen cap.
<strong>Note:</strong> <em>This article covers the U.S. Wegovy single-dose injection pen. Storage rules may differ for Wegovy FlexTouch pens, prefilled syringes, tablets, and products supplied outside the United States.</em>
If you are wondering whether Wegovy needs to be refrigerated or how long it can remain outside the fridge, the answer depends on the product form and storage temperature.
Quick Answer
A U.S. Wegovy single-dose pen should normally be refrigerated at <strong>36°F to 46°F (2°C to 8°C)</strong>. If needed, before the cap is removed, it may be kept in its original carton at <strong>46°F to 86°F (8°C to 30°C) for up to 28 days</strong>. Do not use a pen that has been frozen, exposed to temperatures above 86°F, exposed to light, or kept outside refrigeration for 28 days or longer.

Does Wegovy Need to Be Refrigerated?
Wegovy contains semaglutide and must be stored within the temperature conditions specified in its prescribing information.
Before first use, unopened Wegovy single-dose pens should normally be kept refrigerated between <strong>36°F and 46°F (2°C to 8°C)</strong>. When stored as directed, an unopened pen may be kept refrigerated until the expiration date printed on the package.
Keep the pen refrigerated in its original carton. Do not store it in the freezer or directly next to the refrigerator cooling element.
How Long Can Wegovy Be Out of the Fridge?
If refrigeration is unavailable or you need to carry your pen with you, <strong>can Wegovy be stored at room temperature or outside the fridge?</strong>
According to the official U.S. prescribing information, a Wegovy single-dose pen can remain at <strong>46°F to 86°F (8°C to 30°C) for up to 28 days</strong> prior to removing the pen cap.
Essential Rules for Non-Refrigerated Storage:
- 1<strong>28-Day Limit:</strong> If the pen is kept outside refrigerated storage at 46°F to 86°F (8°C to 30°C), it may remain under those conditions for up to 28 days before cap removal. Record when non-refrigerated storage begins, and ask a pharmacist if the storage history is unclear.
- 2<strong>Light Protection:</strong> Keep the pen cap on and leave the pen in its original carton until administration to protect it from light.
- 3<strong>Maximum Temperature Ceiling:</strong> Never expose the pen to temperatures above 86°F (30°C). If a pen has been exposed to temperatures above 86°F (30°C), do not use it. Follow the disposal instructions or contact a pharmacist or Novo Nordisk if the exposure conditions are uncertain.
Can Wegovy Be Put Back in the Refrigerator?
The U.S. prescribing information states that, if needed, a Wegovy single-dose pen may be kept at 46°F to 86°F (8°C to 30°C) for up to 28 days before the cap is removed. It does not provide detailed instructions for repeatedly moving a pen between refrigerated and non-refrigerated storage or for resetting the storage period. If the storage history is uncertain, contact a pharmacist or Novo Nordisk before using the pen.
Rules for Traveling with Wegovy
When <strong>traveling with Wegovy</strong>, careful preparation can reduce the risk of accidental heat exposure or freezing:
- 11. <strong>Keep Wegovy in Your Carry-On Bag:</strong> Keeping Wegovy in your carry-on bag allows you to monitor its temperature and reduces the risks associated with lost luggage, excessive heat, or freezing. Check the medication and security requirements for every airport and country on your itinerary.
- 22. <strong>Prevent Direct Ice Contact:</strong> If traveling in warm weather with a cooling wallet or insulated pouch, make sure the pen is buffered so it does not directly touch ice or frozen gel packs, which can freeze the liquid.
- 33. <strong>Retain Original Packaging:</strong> Keep the pen in its original carton to protect it from light. Carry the prescription label or supporting documentation when available, particularly for international travel, and check the entry requirements of your destination.
What to Do If Wegovy Freezes or Is Exposed to High Heat
- 1<strong>If Frozen:</strong> Do not use Wegovy if it has been frozen, even if the pen later thaws and the solution looks normal.
- 2<strong>If Heated Above 86°F (30°C):</strong> Do not use a pen that has been exposed to temperatures above 86°F (30°C).
- 3<strong>Visual Inspection Before Use:</strong> Check the pen and expiration date before use. The medicine should appear clear and colorless through the pen window. Do not use the pen if the solution appears cloudy or colored or contains particles. A normal appearance does not override the storage rules: do not use a pen that has been frozen, exposed to temperatures above 86°F (30°C), exposed to light, or kept outside refrigeration for 28 days or longer.
