PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 21193765Guggenheimer/2011N/ASystematic Review
Key resultsIncreased use of acetaminophen has increased the number of cases of hepatotoxicity. Since acetaminophen is found in many analgesics, unintentional overdose can occur.
Evidence Search Liver toxicity and acetaminophen
Comments on
The Evidence
The study is a systematic review of articles. The authors reviewed the literature in which investigators examined data related to the epidemiology of APAP-related liver toxicity, studies in which the investigators evaluated the risk factors for its occurrence and case reports. They included articles that were used by the FDA as the basis for establishing the new labeling requirements. Overall, it was found that the use of acetaminophen has caused a substantial increase in the number of cases of acute liver failure.
Applicability When prescribing acetaminophen to patients with post-operative pain risk factors for hepatotoxicity should be considered.

A PubMed search was performed October 2014. More recent evidence was found to support the conclusion of the CAT. Notably expert opinion by McGill 2014, PubMed: 24836926 showing mechanism of action of APAP-related hepatotoxicity, and a literature review by Blieden 2014, PubMed: 24678654 support the 2011 review cited.
