Zepbound release date?

When did Zepbound first launch?

Zepbound (tirzepatide) was released in the U.S. in late 2023, shortly after its approval. The drug’s first availability date is commonly cited as November 2023 following FDA approval.

Why does the “release date” vary by source?

Different sites may list different dates depending on what they mean by “release,” such as:
- FDA approval date (when it was authorized)
- First commercial shipment / pharmacy availability
- First reported start of prescribing in practice

If you’re looking for the specific “first day patients could get it” in the U.S., that can differ from the approval date.

What you may be looking for if you meant FDA approval

People often search “release date” when they actually want the FDA approval date (the date the product became legally available to market). That date is the cleanest reference point if your goal is regulatory timing.

Patent/exclusivity timing (if you’re using the release date for market research)
