title: Risperidone-induced cholestatic hepatitis.
abstract: Risperidone, a widely used atypical and potent neuroleptic drug, is assumed to induce fewer hepatic side-effects than phenothiazine anti-psychotics. Recently, we observed a case of risperidone-induced cholestatic hepatotoxicity. A 37-year-old male developed a rapid increase in liver enzymes and cholestatic parameters after starting treatment with risperidone for paranoid psychosis. Work-up for other potential aetiologies was negative. The results of a percutaneous liver biopsy were consistent with drug-induced liver injury and cholestasis. Over the course of one month after the discontinuance of all anti-psychotic agents, the liver function test results returned to near-normal values. This observation supports the need to monitor cholestatic parameters in addition to liver function enzymes during initiation and the first weeks of risperidone intake.
