Patients who took the frequently prescribed diabetes and weight-loss drugs Ozempic and Wegovy faced a greater risk of a stroke of the optic nerve, which can lead to blindness, according to a new study by Mass General Brigham researchers.
The study says people prescribed semaglutide, sold under the brands Ozempic for diabetes or Wegovy for weight loss, were more likely to be diagnosed with a rare condition called NAION than those with diabetes or obesity who did not take the medications. Researchers cautioned they have no evidence that semaglutide causes this potentially blinding condition, merely that the study found patients taking the diabetes or weight-loss medication faced a greater risk of developing it.
