OUTCOME FOR THE CASE PATIENT
Following discharge, the patient was monitored closely with regular clinic visits and blood work. Her liver test results improved gradually, with consideration of a repeat biopsy to evaluate for overlap or missed autoimmune disease. Her repeat ANA was negative and IgG was within normal limits. Within three months of admission, her liver tests normalized and repeat biopsy was deferred.

Upon review of the herbal beauty supplement the patient reported taking, shark cartilage was noted as a primary ingredient. In a case report, shark cartilage was identified as a hepatotoxin.25 The patient was advised never to ingest the offending supplement, or any other substances not regulated by the FDA, again. Furthermore, the offending medication was listed as a medication allergy in her electronic health record.

CONCLUSION
It is crucial to emphasize to patients the potential hepatotoxicity of medications and herbal and dietary supplements, especially OTC medications that pose an overdose risk. Patients should review all new supplements with their providers prior to therapy initiation. With known hepatotoxins, providers should closely monitor patients for liver injury while treatment is ongoing. In suspected cases of DILI, a thorough history and physical exam will greatly inform the diagnosis. In the majority of cases, the suspect medication should be discontinued immediately, with subsequent assessment of liver response. Identification of DILI early in the course increases the likelihood of full hepatic recovery and improves patient outcomes.
