Abstract
Background : In a retrospective study in 4 Belgian hospitals, we showed that the use of linezolid (LZD) was larger and the rate of adverse drug reactions (ADRs) higher (especially anemia and thrombocytopenia) than described in the summary of product characteristics (1). Associated risk factors for ADRs were long treatment duration, renal impairment at the treatment initiation, and presence of comorbidities (evaluated by the Charlson index (2)). Moreover, literature suggests that trough levels (Cmin) > 9 mg/L increase the risk of hematological toxicity (HT) [...].
