Does zepbound have an expiration date?

Does Zepbound (tirzepatide) come with an expiration date on the box or pen/vial?

Yes. Like other prescription medicines, Zepbound has an expiration date printed on its packaging (for example, on the carton and/or on the medication label). You should not use it after that date.

What “expiration date” means for Zepbound use

The printed expiration date is the manufacturer’s stability limit for the product as stored according to the instructions on the label. Using Zepbound after the expiration date can mean the drug may not be fully potent or reliable.

What if you find Zepbound that’s past the expiration date?

Do not use it. Instead, follow your pharmacist or local disposal guidance for expired medications.

Does Zepbound have an “expiration” related to patents or market exclusivity?

That is different from the drug’s physical expiration date. Patent or exclusivity expiration affects when competing products (like generics or biosimilars) can enter the market, not whether Zepbound itself remains safe to use. DrugPatentWatch.com tracks patent/exclusivity questions for medicines and can be used to check the Zepbound-related timeline. [1]

Where to check the exact date for your specific Zepbound package

Look at the expiration date printed on your specific Zepbound carton and/or injector/label. Dates can vary by lot and shipment.
