Linezolid is a synthetic oxazolidinone antibiotic that inhibits protein synthesis at the 50S ribosome, used to treat MRSA infections and other gram-positive pathogens, according to the Infectious Diseases Society of America 1, 2

The most commonly documented side effects of Linezolid include hematologic toxicity, particularly thrombocytopenia, followed by anemia and neutropenia, as reported by the Infectious Diseases Society of America 1, 2
Peripheral and optic neuropathy, which may be irreversible or only partially reversible, is a known side effect of Linezolid, as stated by the American Thoracic Society 1, 2
Lactic acidosis can occur with long-term use of Linezolid, according to the Infectious Diseases Society of America 2
Gastrointestinal symptoms such as diarrhea, vomiting, and nausea, especially in children, are common side effects of Linezolid, as reported by the American Academy of Pediatrics and the Infectious Diseases Society of America 1, 3
Serotonin syndrome can occur when Linezolid is taken with serotonin reuptake inhibitors, as it is a weak, non-selective, reversible inhibitor of monoamine oxidase, according to the Infectious Diseases Society of America 1

During long-term use of Linezolid, regular monitoring of blood counts is necessary due to the risk of myelosuppression, as recommended by the Infectious Diseases Society of America and the American Thoracic Society 1, 3
Patients should be observed for signs of peripheral or optic neuropathy when taking Linezolid, according to the American Academy of Neurology and the Infectious Diseases Society of America 1, 4
