Ozempic lawsuit: gastroparesis and vision loss claims
Lawsuits over Ozempic and other GLP-1 drugs fall into two federal groups: claims of severe stomach and intestinal problems, and claims of sudden vision loss called NAION. Both are before the same federal judge in Philadelphia. No trial dates or settlements have been announced.

Which drugs are involved
Claims name semaglutide products (Ozempic, Wegovy and Rybelsus) made by Novo Nordisk and tirzepatide products (Mounjaro and Zepbound) made by Eli Lilly. These drugs are approved to treat type 2 diabetes or for weight management.
Stomach and intestinal injury claims (MDL 3094)
Plaintiffs allege the manufacturers did not adequately warn about gastroparesis (delayed stomach emptying), ileus and intestinal blockage. As of October 1, 2026, the federal panel reported 4,025 pending cases before Judge Karen S. Marston in the Eastern District of Pennsylvania.

A separate MDL created in December 2025 covers claims of non-arteritic anterior ischemic optic neuropathy (NAION), a sudden loss of vision that is often permanent. It had 247 pending cases as of October 1, 2026, before the same judge. European regulators added NAION as a very rare side effect of semaglutide in 2025; plaintiffs argue U.S. labels should also warn about it.
JPML: Pending MDL dockets by actions pending (October 1, 2026) ↗Where the cases stand
Both MDLs are in pretrial stages. The court has prioritized early questions such as whether the drugs can cause the alleged injuries and whether the warnings were adequate. No bellwether trials or global settlement have been announced, and any settlement figures you see online are estimates.
Records that matter
Prescription and pharmacy records showing which drug you took and when, medical records documenting the diagnosis (for example a gastric emptying study or an eye exam confirming NAION), and records of other conditions that could explain the injury.
Keep taking prescribed medicine until you talk to your doctor
A lawsuit is not medical advice. Do not stop or change a prescribed medicine without talking to the prescriber, and seek urgent care for sudden vision loss or severe abdominal symptoms.
Deadlines
Each state sets its own filing deadline, and the clock often starts when you knew or should have known about the injury and its possible cause. Joining an MDL does not pause your state’s deadline, so ask a lawyer promptly if you are considering a claim.
Talking to a lawyer
Mass tort lawyers usually work on contingency, meaning they are paid a percentage of any recovery. Ask how the fee is calculated, which costs you could owe, whether your case would be filed in the MDL or in state court, and who will handle it day to day. SettlementLift is not a law firm and does not take or refer these cases.
ABA: Questions to ask a lawyer ↗Frequently asked questions
Is there an Ozempic class action?
Most federal claims are individual cases grouped in two MDLs, not a single class action. Each person must show their own injury and its connection to the drug.
Has there been an Ozempic settlement?
No global settlement had been announced as of October 19, 2026.
