Myelosuppression and Serotonin Syndrome Associated with Concurrent Use of Linezolid and Selective Serotonin Reuptake Inhibitors in Bone Marrow Transplant Recipients

Abstract

We report 2 cases of serotonin syndrome and myelosuppression in bone marrow transplant recipients who received linezolid in combination with a selective serotonin reuptake inhibitor (SSRI). Given the risks to patients in this high-risk group, we recommend that this combination of medications be avoided if alternative antibiotic therapy is possible. If no alternative therapy is possible, prescribers should discontinue SSRI therapy and monitor these patients closely for evidence of serotonin syndrome or the development of hematological toxicity.
