INTRODUCTION: Drug-induced liver injury is an important adverse effect and can be caused by various medications, including novel therapeutic agents. The risk stratification of patients susceptible to DILI is a growing field. AREAS COVERED: The current article highlights new studies on risk stratification regarding risk factors of DILI, prediction of liver injury, and predictors of severe outcomes. Studies on patient demographic and genetic risk factors are discussed, in addition to the potential role of concomitant medications that may affect the risk of DILI. EXPERT OPINION: Although much is known about patient risk factors for DILI, a better combination of these factors into risk scores is needed to predict which patients are particularly susceptible. Knowledge of these risk factors might determine drug treatment in the near future, as well as the need for routine monitoring of liver tests.
