## Lawsuits Target GLP-1 Drugmakers
Hundreds of lawsuits have been filed against major GLP-1 makers Eli Lilly and Novo Nordisk with patients accusing the popular weight-loss drugs of causing permanent eye damage and vision loss.
## NAION Linked to Vision Loss
The lawsuits focus on non-arteritic anterior ischemic optic neuropathy, a condition causing rapid-onset vision changes and loss that can result in blindness.
## Drugmakers Omitted Warning Labels
The lawsuits claim drugmakers should have known about and informed patients of the potential for NAION, which is not included on U.S. warning labels but exists in some international labels.
## Thousands Report Serious Complications
Thousands of lawsuits allege serious complications including NAION and gastrointestinal injury, with hundreds specifically claiming NAION damage.
## Case Study: Vision Loss Timeline
A 63-year-old man prescribed Ozempic for diabetes in 2023 lost vision in one eye four months later and later in both eyes, becoming legally blind by 2024.
## Drugmakers Deny Connection
Both Novo Nordisk and Eli Lilly have denied any significant relationship between their medications and vision loss, stating patient safety is their top priority.
## Key takeaway

Patients claim Ozempic, Wegovy, and Mounjaro caused permanent vision loss through NAION.
