Underlying liver disease is a risk factor for drug-induced liver injury and may complicate the differential diagnosis of acute transaminitis in patients taking medications associated with hepatotoxicity. Ms L presented with 2 months of new psychotic symptoms resulting in hospitalizations. Although psychosis previously improved with haloperidol, she reported symptoms concerning for akathisia. Restlessness improved and psychotic symptoms resolved after initiation of olanzapine. Concurrently, her alanine aminotransferase (ALT) was elevated, prompting further workup and new diagnosis of acute hepatitis C. Over the course of hospitalization, her ALT increased exponentially. Initially attributed solely to acute hepatitis C infection, ALT rapidly decreased after holding olanzapine, implying it was contributing to her liver injury. Subsequently, given her prior response, haloperidol was retrialed with close monitoring for adverse effects. Her subjective restlessness was treated with additional agents, and she was then transitioned to monthly haloperidol decanoate injections to further assist her adherence. Prior to discharge, she had resolution of psychosis and transaminitis. Olanzapine may contribute to hepatotoxicity with concurrent viral hepatitis, and clarity can be obtained by a trial of stopping the suspected medication. Furthermore, olanzapine, when combined with underlying liver disease, may have an additive effect on liver injury, resulting in accelerated elevations in liver aminotransferases.<\/jats:p>","DOI":"10.9740\/mhc.2022.06.210","type":"journal-article","created":{"date-parts":[[2022,6,10]],"date-time":"2022-06-10T11:17:19Z","timestamp":1654859839000},"page":"210-213","source":"Crossref","is-referenced-by-count":4,"title":["Identifying olanzapine induced liver injury in the setting of acute hepatitis C: A case report"],"prefix":"10.9740","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5099-2245","authenticated-orcid":true,"given":"Andrea","family":"Brelje","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8381-8278","authenticated-orcid":true,"given":"Bailey","family":"Fay","sequence":"additional","affiliation":[{"name":"2 Resident Physician, Department of Psychiatry, University of Michigan Hospital, Ann Arbor, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1971-6215","authenticated-orcid":true,"given":"Scott","family":"Mariouw","sequence":"additional","affiliation":[{"name":"3 Assistant Professor, Department of Psychiatry, University of Michigan Hospital, Ann Arbor, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2294-2694","authenticated-orcid":true,"given":"Amy","family":"VandenBerg","sequence":"additional","affiliation":[{"name":"4 Adjunct Clinical Associate Professor, College of Pharmacy, University of Michigan, Ann Arbor, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4719","published-online":{"date-parts":[[2022,6,10]]},"reference":[{"key":"2022061015152557700_i2168-9709-12-3-210-b01","doi-asserted-by":"crossref","unstructured":"Bernal\n              W,\n            \n            \n              Wendon\n              J.\n            \n          \n          Acute liver failure.\n\t\t\t\t\tN Engl J Med.\n\t\t\t\t\t2013;\n\t\t\t\t\t369(26):\n\t\t\t\t\t2525-\n\t\t\t\t\t34.\n\t\t\t\t\tDOI: 10.1056\/NEJMra1208937.
