What “expiry date” means for Wegovy (and where to find it)
Wegovy’s expiry date is the date shown on the label of your specific pen. You should not use the medicine after that date. The label is the most reliable source because it can vary by batch and production date.
How long Wegovy lasts after opening or first use
If you’re asking about shelf life beyond the printed expiry date, the key detail is whether the pen has been started (first use) and how it’s been stored. Storage rules can differ depending on whether the pen is unopened versus in use, and they also depend on manufacturer instructions for that presentation.
Can patients use Wegovy past the printed expiry date?
No. Using Wegovy past its labelled expiry date is not recommended because drug potency can decline over time and the manufacturer’s stability testing only covers up to that date.
What to do if your Wegovy looks expired or has temperature issues
If the pen’s label shows it’s expired, or if it may have been exposed to temperatures outside recommended storage conditions, you generally should not use it and should contact your pharmacist for guidance on replacement and safe handling.
How to check the exact expiry date on your pen
Look for the expiry/best-by date printed on the Wegovy carton and the pen label (often alongside other batch/lot information). If you tell me the exact wording on your label (for example “EXP” or “Use by”) and whether the pen has been started, I can help interpret what that date means for your situation.
Related: patent “expiry” vs medicine expiry
Sometimes people search “Wegovy expiry” meaning drug exclusivity or patent expiration rather than the expiration date on the prescription pen. If that’s what you meant, share whether you want regulatory exclusivity/patent timelines instead of the medicine’s use-by date.
If you want, paste the expiry wording from your Wegovy box/pen (no personal info), and tell me whether it has been used yet.
