title: Adolescents' misperceptions of the dangerousness of acetaminophen in overdose.
abstract: Clinical observations suggest that adolescents commonly and naively use acetaminophen in suicide attempts even when they do not wish to die. It is estimated that 18,500-mg acetaminophen tablets can lead to hepatotoxicity, while death is usually associated with ingestion of 50 or more tablets. A sample comprising 569 adolescent students completed an author-designed survey assessing teenagers' knowledge of acetaminophen's therapeutic and harmful effects. The findings support our original data that adolescents have ready access to acetaminophen and use it in suicide attempts, but underestimate its potential for toxicity. Forty-two percent of this sample underestimated the dose to cause harm, believing it would require 20 or more tablets, and 50% underestimated the dose to cause death, stating 100 or more pills would be necessary. Adolescents appear to seriously underestimate the dangerousness of acetaminophen in overdose, and lack knowledge regarding side effects of overdose.
