FDA Issues Warning on GLP‑1
Tap title to read story
The Food and Drug Administration on Monday warned that GLP‑1 drugs carry a potential risk for a rare but serious eye condition and required pharmaceutical companies to inform patients and doctors of the risk. The condition, called non‑arteritic anterior ischemic optic neuropathy, or NAION, is sometimes referred to as an “eye stroke” and is caused by insufficient blood flow to the optic nerve. It typically causes sudden vision loss and, in severe cases, can lead to blindness. There are currently no proven treatments for the condition. GLP‑1 drugs such as Novo Nordisk’s Ozempic and Wegovy and Eli Lilly’s Mounjaro and Zepbound have exploded in popularity for their potent weight‑loss effects, but side effects can appear in real‑world use that weren’t observed in clinical trials.
