Danger of sudden vision loss: the new FDA warning about GLP-1 weight loss injections
The FDA ordered manufacturers of GLP-1 drugs, including Ozempic, Wegovy, Mounjaro, and Zepbound, to add warnings about rare optic nerve damage risk. The warning follows a review of clinical trials and studies showing a higher incidence of non-arteritic anterior ischemic optic neuropathy (NAION) in patients using these drugs. Novo Nordisk and Eli Lilly, manufacturers of these drugs, have responded to the FDA's announcement.
