FDA warns about alarming eye risk with GLP-1 drugs after dozens sue over vision loss tied to the medication
The FDA warned about a potential eye condition, NAION, linked to GLP-1 drugs. It requires manufacturers like Novo Nordisk (Wegovy, Ozempic) and Eli Lilly (Zepbound, Mounjaro) to update packaging warnings. Lawsuits allege insufficient warnings, while evidence of a link remains mixed. Both companies prioritize patient safety and monitor the issue.
