The aim of the present case report is to describe a potential interaction between valproic acid and oxcarbazepine that resulted in hepatic injury.
We report the case of a 46-year-old man with schizoaffective disorder who was cross-titrated from valproic acid to oxcarbazepine because of liver injury.
Initiation of oxcarbazepine four days after stopping valproic acid produced a significant elevation in liver enzymes that normalized with oxcarbazepine discontinuation and did not reappear with its reintroduction five days later.
Our findings suggest that a longer washout period or another agent should be considered when transitioning from valproic acid to oxcarbazepine.
