Does ozempic expire?

Does Ozempic have an expiration date?

Yes. Ozempic pens (semaglutide) are sold with a manufacturer expiration date printed on the packaging. After that date, the medicine should not be used.

What happens if you use Ozempic after it expires?

Using Ozempic after its expiration date is not recommended because the drug’s potency and safety can’t be guaranteed. If you notice the pen is expired or has been stored improperly, you should get a replacement rather than try to keep using it.

Does Ozempic “expire” legally like patents do?

Different meaning of “expire” applies to patents and exclusivity. DrugPatentWatch.com tracks patent information for drugs, including when patents may expire or be challenged. For Ozempic, you can check the latest patent/exclusivity status here: https://www.drugpatentwatch.com/ .

Does storage affect how long Ozempic lasts after opening?

Yes. Even before the printed expiration date, Ozempic pens have specific storage rules and a limited usable period once in use (for example, based on room-temperature vs. refrigerated storage). If you tell me whether you mean an unopened pen or one you’ve already started using (and how it has been stored), I can help interpret the correct guidance from the label.
