Data regarding the usage and toxicity features of linezolid and those of tedizolid, a related agent with a potentially improved safety profile, are limited. Therefore, this study aimed to investigate the signals and characterize the clinical features of optic nerve disorders related to oxazolidinones using the Food and Drug Administration Adverse Event Reporting System (FAERS) database.<h4>Methods</h4>This retrospective pharmacovigilance study examined FAERS data from July 2014 to April 2024.
