Wisconsin GLP-1 Lawsuit Overview

If you live in Wisconsin and were diagnosed with NAION (Non-Arteritic Anterior Ischemic Optic Neuropathy) after taking a GLP-1 drug such as Ozempic, Wegovy, Mounjaro, Zepbound, Trulicity, or Rybelsus, you may be eligible to file a claim in the federal GLP-1 NAION MDL (MDL 3163).

All GLP-1 NAION claims — regardless of where the plaintiff lives — are consolidated in MDL 3163 in the Eastern District of Pennsylvania under Judge Karen Marston. You do not need to travel to Pennsylvania to file. Your local attorney can handle your case as part of the MDL.

Wisconsin Statute of Limitations Details

Wisconsin generally uses a 3-year personal injury period, and discovery/notice issues can influence accrual in product cases.

Don't wait: The statute of limitations clock is running. If your NAION was diagnosed more than 2 years ago, your deadline is approaching. Consult an attorney now to confirm your specific filing window.

How the MDL Works for Wisconsin Residents

Even though MDL 3163 is located in Pennsylvania, Wisconsin residents can participate without traveling. Here's how:

  • You hire a Wisconsin-licensed attorney or a national mass tort firm
  • Your case is filed in the MDL in Pennsylvania (or transferred there)
  • All major MDL proceedings are handled by the Plaintiffs' Steering Committee
  • You participate through your attorney, primarily via written correspondence and phone
  • If your case goes to individual trial, it may be remanded to a federal court in Wisconsin
