Although acetaminophen and salicylate toxicity are well studied, controversies remain regarding management. This review presents a systematic approach to the emergency department management of patients with acetaminophen or salicylate toxicity, including discussion of the tools used to assess severity, guide treatment decisions, and determine prognosis.
