2ADVERSE REACTIONS
The following clinically significant adverse reactions are described elsewhere in the labeling:
- Myelosuppression [
- Peripheral and Optic Neuropathy [
- Serotonin Syndrome [
- Clostridioides difficile-Associated Diarrhea [see ]
- Lactic Acidosis [
- Convulsions [
- Rhabdomyolysis [
- Hypoglycemia [
- Hyponatremia and/or Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) [
2.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
2.2Postmarketing Experience
The following adverse reactions have been identified during post-approval use of ZYVOX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure:
- Anaphylaxis, angioedema, bullous skin disorders including severe cutaneous adverse reactions (SCAR) such as toxic epidermal necrolysis and Stevens-Johnson syndrome, and hypersensitivity vasculitis.
- Myelosuppression (including anemia, leukopenia, pancytopenia, and thrombocytopenia). Thrombocytopenia has been reported more often in patients with severe renal impairment and in patients with moderate to severe hepatic impairment [
- Peripheral neuropathy, and optic neuropathy sometimes progressing to loss of vision [
- Serotonin syndrome has been reported in patients receiving concomitant serotonergic agents, including antidepressants such as selective serotonin reuptake inhibitors (SSRIs) and opioids, and ZYVOX [
- Lactic acidosis [
- Convulsions [
- Rhabdomyolysis [
- Hypoglycemia, including symptomatic episodes [
- Hyponatremia and/or Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) [
- Superficial tooth discoloration and tongue discoloration have been reported with the use of linezolid. The tooth discoloration was removable with professional dental cleaning (manual descaling) in cases with known outcome.
3OVERDOSAGE
In the event of overdosage, supportive care is advised, with maintenance of glomerular filtration. Hemodialysis may facilitate more rapid elimination of linezolid. In a Phase 1 clinical trial, approximately 30% of a dose of linezolid was removed during a 3-hour hemodialysis session beginning 3 hours after the dose of linezolid was administered. Data are not available for removal of linezolid with peritoneal dialysis or hemoperfusion. Clinical signs of acute toxicity in animals were decreased activity and ataxia in rats and vomiting and tremors in dogs treated with 3,000 mg/kg/day and 2,000 mg/kg/day, respectively.
