"Consider Discontinuing": FDA Slaps "Eye Stroke" Warning On All GLP-1 Weight-Loss Drugs

The FDA requires warnings on all GLP-1 drugs, including Ozempic, Wegovy, Mounjaro, and Zepbound, for a potential increased risk of NAION, a condition that can cause sudden vision loss. The agency's review found 10 cases among patients on GLP-1 drugs compared to 5 on placebo. The FDA advises clinicians to consider discontinuing the drug in patients who develop NAION, unless the benefits outweigh the risks.
