What is known and objective
Treatment of tacrolimus toxicity includes holding tacrolimus and supportive care. The objective is to describe considerations for pharmacologic induction of tacrolimus metabolism.
Case description
A 52‐year‐old male with a failed renal transplant on chronic haemodialysis developed tacrolimus toxicity due to a drug‐drug interaction with darunavir/ritonavir. Tacrolimus concentrations were >60 ng/mL for 10 days despite holding tacrolimus and darunavir/ritonavir. Development of encephalopathy prompted initiation of phenytoin to induce tacrolimus metabolism. Tacrolimus concentration was <2 ng/mL within 4 days and mental status normalized.
What is new and conclusion
Phenytoin metabolic induction is a therapeutic option for prolonged tacrolimus toxicity.
Tacrolimus toxicity lasting 10 days was successfully treated with phenytoin in this case report. Induction of tacrolimus metabolism is a viable option for treatment of toxicity and may have a quick onset. |
