Neural

Patients prescribed semaglutide or tirzepatide had an increased risk of nonarteritic anterior ischemic optic neuropathy (NAION) with a hazard ratio of 1.76.

Clinicians should monitor patients on semaglutide or tirzepatide for signs of NAION.

StrongSupportsmedium confidence
During the 2-year follow-up, there were 35 patients (0.04%) with NAION in the semaglutide or tirzepatide group and 19 patients (0.02%) with NAION in the matched comparison group (hazard ratio, 1.76 [95% CI, 1.01-3.07]).
