Linezolid-induced bradycardia: a case report

We report an episode of severe bradycardia that occurred in a 49-year-old woman with fever and malignant jaundice during antibiotic therapy with linezolid, a new oxazolidinone with activity against Gram-positive cocci. In our case, the strict temporal dependence between bradycardia and linezolid therapy seems to provide strong evidence for a causal relationship. To our knowledge, this is the first report of linezolid-induced bradycardia. This adverse event confirms that the new antibiotic linezolid should be administered with caution in patient with jaundice and hepatic insufficiency.
