Lemborexant fda approval date?

What FDA approval date did lemborexant get?

The FDA approved lemborexant (Dayvigo) on October 23, 2014.

When did lemborexant first become available as a prescription medicine?

The approval date above marks when the drug received FDA authorization; availability can lag slightly due to labeling and distribution steps that follow approval.

Is there more than one “approval date” people might be looking for?

Sometimes searches turn up multiple dates because of:
- Initial NDA/BLA approval (the first FDA authorization date).
- Later label expansions (new indications, dosing, or subpopulations).
- Patent/exclusivity milestones that are not the same as FDA approval.

If you tell me which exact version you mean (initial approval vs. label update), I can narrow it to the right date.
