Abstract
AbstractIntroductionγ‐hydroxybutyrate (GHB) is a GABA‐B agonist that rapidly produces effects that are likened to both alcohol and MDMA/ecstasy. GHB use can lead to neuroadaptation with a characteristic withdrawal syndrome. There is currently a paucity of data on the progression of GHB withdrawal, however, due to the drug's short half‐life it is generally considered to be typically 5–7 days, although some cases can be severe and complicated by life threatening delirium. Here, we present a case of severe GHB withdrawal, which recurred on multiple occasions over 56 days, despite initial clinical stabilisation on each occasion and toxicological evidence of abstinence from GHB between episodes.Case PresentationA male patient in his 30s presented with agitated delirium on a background of severe GHB use disorder with a 15‐year history of daily high dose GHB use. Following 3 hospital admissions over 8 weeks, all requiring intravenous sedation and tracheal intubation, the patient's withdrawal delirium was successfully treated with a slow benzodiazepine and baclofen wean over a period of 6 months. Relapse to GHB use between hospitalisations was excluded toxicologically via blood analysis performed at an institute of forensic pathology.Discussion and ConclusionsThis case highlights that GHB withdrawal can be more prolonged than previously reported in the literature and in some cases may require slow and prolonged tapering of treatment to prevent re‐emergence of delirium. Similar to previous case reports, benzodiazepines and GABA‐B receptor agonists appear to be appropriate drug classes to manage GHB withdrawal.
