Eli Lilly, Novo weight-loss drugs to get rare vision loss warning
The FDA will require a warning on GLP-1 receptor agonist drugs like Eli Lilly's Zepbound and Novo's Wegovy due to a rare eye condition risk. The FDA reviewed adverse event reports and clinical trials, finding a higher incidence rate of NAION in patients using these drugs compared to others. Common risk factors for the condition include smoking, diabetes, and high blood pressure.
