Acetaminophen Poisoning

      In 2003, the American Association of Poison Control Centers reported more than 127,000 exposures involving acetaminophen (acetyl-para-amino-phenol or APAP). Of these exposures, 65,000 patients received treatment in a medical facility, and 16,500 received N-acetylcysteine (NAC). There were 214 deaths involving overdose where an analgesic agent was thought to be primarily responsible. In 62 of these cases, APAP was the single agent involved [

      ]. APAP toxicity is also a major cause of fulminant hepatic failure (FHF) and is implicated in as many as 39% of cases presenting to tertiary care hospitals [
