Which drugs are in the GLP-1 lawsuit: Wegovy, Mounjaro, Zepbound?

Short answer: Eight drugs are at issue in the federal stomach-injury MDL: Ozempic, Wegovy, Rybelsus, Victoza and Saxenda made by Novo Nordisk, and Trulicity, Mounjaro and Zepbound made by Eli Lilly. The court’s August 15, 2025 opinion lists all eight.

All are GLP-1 receptor agonists (Mounjaro and Zepbound also act on a second hormone, GIP). They slow how fast the stomach empties, which helps blood sugar and appetite but is also the basis of the injury claims.

  • Wegovy lawsuit: same MDL and same claims as Ozempic, because both are semaglutide.
  • Mounjaro and Zepbound lawsuits: tirzepatide claims against Eli Lilly in the same MDL.
  • Compounded semaglutide: pharmacy-made versions are not made by these defendants, so they raise different questions.
  • Vision loss: NAION claims go to a separate MDL, 3163.
