BMJ Case Rep. 2023 Nov 30;16(11):e256796. doi: 10.1136/bcr-2023-256796.

Abstract

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.

Keywords: Drug interactions; Medical education; Medical management; Psychiatry (drugs and medicines).
