LegitScript certification

The vocabulary of getting a claim paid, of FDA enforcement, and of what on-label and off-label really mean.

Definition

A commercial certification that an online pharmacy or telehealth operation meets LegitScript's standards; the major ad platforms require it to run pharmaceutical advertising. ⚠ It is a paid private certification, not a regulator's license. Verify any claim in LegitScript's own directory rather than trusting a badge image on a seller's footer.
