No specific antidote is known.
No cases of overdose have been reported. However, the following information may prove useful: Supportive care is advised together with maintenance of glomerular ﬁltration. Approximately 30% of a linezolid dose is removed during 3 hours of haemodialysis, but no data are available for the removal of linezolid by peritoneal dialysis or haemoperfusion.
The two primary metabolites of linezolid are also removed to some extent by haemodialysis.
Signs of toxicity in rats following doses of 3000 mg/kg/day linezolid were decreased activity and ataxia whilst dogs treated with 2000 mg/kg/day experienced vomiting and tremors.
