An Uncommon Side Effect of Rivaroxaban: A Drug-Induced Liver Injury.

Rivaroxaban is rarely associated with drug-induced liver injury (DILI). A 57-year-old male was sent to the emergency room from an endocrine clinic for a presyncope evaluation. His exam was non-focal, and his laboratory work was remarkable for the hepatocellular pattern of liver injury. Upon detailed assessment, he was found to have DILI due to rivaroxaban. The liver function tests improved after its discontinuation. This case emphasizes the need for early recognition and timely intervention to prevent further hepatotoxicity from the culprit drug.
