Introduction: The rational use of drugs is one of the main elements of achieving the best pharmacotherapy method for patients. Linezolid is used for infections caused by gram-positive bacteria, including vancomycin-resistant staphylococci and vancomycin-resistant enterococci, but the inappropriate use of this drug has led to the emergence of linezolid-resistant strains. The purpose of this study was to investigate the manner of Linezolid prescription in Shahid Chamran Hospital of Isfahan City in 2021.
