Drug-Induced Liver Injury Resources and Reporting for the Clinician.

Although many risk factors for developing drug-induced liver injury (DILI) have been identified and more than 1000 medications and herbal and dietary supplements are known to cause liver dysfunction, idiosyncratic drug reactions remain unpredictable and erratic. Varying effects of individual drugs on the event cascade and patient genetic polymorphisms lead to different clinical presentations. Mechanisms and causality scales have been developed to guide the clinician in diagnosis, and several databases and registries are available for reference and reporting. We identify and summarize the resources available to clinicians to help diagnose, manage, and report DILI and to identify hepatotoxic drugs.
