Purpose

  • Acetaminophen has a long history of safe use at therapeutic doses, but can cause liver injury at very high doses
  • The California Office of Environment Health Hazard Assessment (OEHHA) recently called for a scientific review of the carcinogenicity hazard potential of acetaminophen
  • This Quantitative Systems Toxicology work supported this review as part of a broader scientific weight-of-evidence assessment of the carcinogenicity hazard potential of acetaminophen
