Q

Situation where flumazenil can be given for benzodiazepine OD

A
  • Unintentional lone paediatric benzodiazepine ingestion with compromised airway and breathing
  • When benzodiazepine overdose results in compromised airway or breathing in
    settings where resources for intubation are not available
  • Iatrogenic over-treatment with benzodiazepine
  • An elderly patient with respiratory disease/ intubation should be avoided
