An increasing number of people are filing Mounjaro and Ozempic lawsuits for NAION “eye stroke” vision loss in 2026, and that trend is expected to continue in 2027.
Here is a 10-point “explainer” to give you a better understanding of why these people are seeking legal compensation for losing their eyesight, and sometimes essentially becoming blind.
- Non-arteritic anterior ischemic optic neuropathy (NAION) is an eye-related side effect of Mounjaro and Ozempic, as well as other popular medications in the glucagon-like peptide-1 receptor agonists (GLP-1) class of drugs.
- NAION is sometimes called an “eye stroke,” and it occurs when the optic nerve does not receive enough blood flow.
- NAION typically causes sudden vision loss and, in severe cases, can lead to blindness.
- There are currently no proven treatments for NAION.
- The active ingredient semaglutide has been linked to NAION; Ozempic as well as Wegovy are semaglutide-containing drugs.
- The active ingredient tirzepatide has been linked to NAION; Mounjaro as well as Zepbound are tirzepatide-containing drugs.
- As of September 2026, the drug labels for Ozempic, Wegovy, Mounjaro, and Zepbound do not include warnings about the NAION eye-related side effect of these medications and other GLP-1 drugs.
- Based on this failure to warn about NAION and the vision loss resulting from this serious side effect, NAION drug injury lawsuits have been filed against the responsible pharmaceutical companies seeking legal compensation for patients diagnosed with NAION and suffering vision loss.
- These lawsuits for NAION “eye stroke” vision loss for patients using Ozempic or Wegovy are being filed against the responsible drug company, Novo Nordisk, which last week announced it had shortened its name to “Novo”.
- Drug injury lawsuits for NAION “eye stroke” vision loss involving Mounjaro or Zepbound are being filed against Eli Lilly.
