What happened
The FDA on Monday warned that GLP-1 drugs carry a potential risk for a rare but serious eye condition sometimes called an "eye stroke" [3]. It required pharmaceutical companies to inform patients and doctors of the risk [3].
The FDA warned that GLP-1 drugs carry a potential risk for a rare but serious eye condition and required pharma companies to inform patients and doctors [3]. Headlines from CNN and the Financial Times also report that the agency ordered new warnings, naming Ozempic and Zepbound in the CNN headline [1][2].
The condition is called non-arteritic anterior ischemic optic neuropathy, or NAION, and is caused by insufficient blood flow to the optic nerve [3]. It typically causes sudden vision loss and, in severe cases, can lead to blindness [3].
STAT reports there are currently no proven treatments for the condition [3]. It adds that side effects can show up in real-world use that were not observed in clinical trials [3].
