U.S. Lawsuits Allege Vision Loss from GLP-1 Drugs Ozempic and Wegovy
A growing number of lawsuits in the U.S. are alleging that GLP-1 class drugs, including Ozempic and Wegovy, are causing non-arteritic anterior ischaemic optic neuropathy (NAION), a condition leading to sudden, potentially irreversible vision loss. Over 90 lawsuits have been filed against Novo Nordisk in New Jersey, with additional cases in federal court in Pennsylvania, targeting manufacturers like Novo Nordisk (Ozempic, Wegovy) and Eli Lilly (Mounjaro, Zepbound). Plaintiffs claim that these manufacturers failed to adequately warn patients about the risk of NAION. NAION, often described as an 'eye stroke,' results from reduced blood supply to the optic nerve and typically affects one eye. While the U.S. Food and Drug Administration (FDA) is investigating the possible link, it has not yet added a specific NAION warning to GLP-1 drug labels. Manufacturers dispute these allegations, with Novo Nordisk stating its research found no increased risk.
