Ozempic, Wegovy and Mounjaro face US lawsuits over rare vision-loss risk

Dozens of U.S. lawsuits target Novo Nordisk, Eli Lilly, and other manufacturers of GLP-1 drugs like Ozempic, Wegovy, Mounjaro, and Zepbound, alleging the medicines caused a rare eye condition (NAION) that can lead to permanent vision loss. Novo Nordisk denies the claims, while Eli Lilly is reviewing data. Research on the link remains inconclusive, and no NAION warning has been added to the drugs.
