Quick Answer: What to Do With Frozen or Unrefrigerated Wegovy?
Do not use frozen Wegovy. Freezing destroys the active peptide structure of semaglutide, rendering it ineffective and potentially unsafe. If your Wegovy has been frozen, even if it has thawed, you must safely discard it. However, if you simply forgot to refrigerate your Wegovy, the manufacturer guidelines state that Wegovy can be kept at room temperature (between 46°F and 86°F, or 8°C and 30°C) for up to 28 days. As long as it hasn’t exceeded 28 days or 86°F (30°C), it is still safe to use.
Understanding Wegovy Storage Guidelines
Proper Refrigeration
Wegovy should ideally be stored in the refrigerator between 36°F and 46°F (2°C to 8°C). Keeping it in its original carton helps protect it from light. It’s best to keep it on a middle shelf rather than near the cooling element at the back, which increases the risk of it becoming frozen Wegovy.
Room Temperature Storage
If needed, you can store your Wegovy pen outside of the refrigerator for up to 28 days, provided the temperature never exceeds 86°F (30°C). Keep the pen cap on until you are ready to inject. Once the 28 days have passed, any unused medication must be discarded.
Why Freezing Ruins Wegovy (Wegovi Eingefroren)
Wegovy contains semaglutide, which is a delicate protein-based medication. When liquid medications like this are frozen, the ice crystals physically break apart the peptide bonds. Once thawed, the medication will not re-form correctly. Using it in this state means you will likely not receive the correct dose, and it may cause unexpected side effects or simply not work for weight loss or blood sugar management. If you accidentally freeze it (a common issue sometimes searched as wegovi eingefroren), you must throw it away.
Frequently Asked Questions
I forgot to refrigerate my Wegovy. Has it gone bad now?
Not necessarily. Wegovy can be safely kept at room temperature (up to 86°F or 30°C) for a maximum of 28 days. If it has been out for less time than this and kept away from extreme heat, it is still safe and effective.
Can I put my Wegovy back in the fridge after leaving it out?
Yes, but putting it back in the refrigerator does not reset the 28-day room-temperature expiration clock. You still need to use it within 28 days of the first time it reached room temperature.
What should the liquid inside the pen look like?
Before using your Wegovy pen, check the window. The liquid should be clear and colorless. If it looks cloudy, discolored, or contains floating particles, do not use it.
