Abstract

Background: Benzodiazepines are also used as intoxicants. This can be dangerous, particularly in multi-substance abuse. We describe cases of acute poisoning related to substance abuse of benzodiazepines in patients at the main A&E clinic in Oslo.

Material and method: We included all patients treated for substance abuse poisoning with benzodiazepines and/or z-hypnotics at the Oslo Accident and Emergency Outpatient Clinic from 1 October 2013 to 30 September 2015. The patients were found through a retrospective review of the A&E clinic's registers. Data were taken from patient records. Diagnosis of the toxic agent was based on the attending doctor's recorded clinical evaluation.

Results: Of 1 037 cases, 787 (76 %) were men. The median age was 36 (interquartile range 28-46, range 14-78). Clonazepam (Rivotril) was the most frequently occurring drug, with 575 cases (55 %), followed by diazepam (Stesolid, Valium, Vival) 158 (15 %), alprazolam (Xanor) 125 (12 %) and oxazepam (Sobril) 94 (9 %). Zopiclone (Imovane, Zopitin) and zolpidem (Stilnoct) occurred rarely, in 25 (2 %) and 11 (1 %) cases, respectively. Benzodiazepines were combined with other intoxicants in 936 (90 %) cases, most frequently heroin 484 (47 %), ethanol 321 (31 %) and amphetamine 199 (19 %).

Interpretation: In substance abuse poisoning, benzodiazepines were very often combined with other intoxicants, most frequently opioids, ethanol and/or amphetamine.
