There is limited information about sodium valproate-induced hyperammonaemia encephalopathy (VPAIHE). The aim of this case report is to provide medical practitioners with a greater awareness of the possible development of hyperammonaemia due to sodium valproate use and its associated complications.This paper describes a middle-aged man with a history of bipolar affective disorder who was admitted with a manic relapse secondary to medication non-compliance. His admission was complicated by an intensive care unit admission to manage medical compromise in the context of sodium VPAIHE.
