Core Tip A middle-aged woman with metastatic colon cancer on immune checkpoint immunotherapy presented with acute hepatocellular injury. This case highlights severe fenbendazole-induced hepatocellular injury in an oncology patient receiving immune checkpoint inhibitors, where timing and causality assessment were vital for accurately attributing the liver injury. Social media-driven self-medication is becoming increasingly common among cancer patients, with fenbendazole doses often far exceeding veterinary recommendations. Prompt recognition and removal of the offending agent can allow safe continuation of immunotherapy and prevent unnecessary immunosuppression. A thorough approach to medication history-taking, including non-prescription and alternative drugs, is essential when evaluating unexplained acute liver injury.
