Clinical pearls

  • Beers Criteria 2023: All benzodiazepines (regardless of duration of action) are potentially inappropriate in elderly — risk of cognitive impairment, delirium, falls, fractures, and motor vehicle accidents
  • STOPP v3: Avoid benzodiazepines in elderly with falls or at risk of falls (increases fracture risk 50%)
  • Paradoxical excitation (increased agitation, aggression) occurs in some elderly patients — discontinue if this occurs
  • Schedule 3 Controlled Drug in UK — prescription requirements apply
  • If already prescribed long-term, gradual tapering is essential — abrupt withdrawal risks seizures and severe anxiety
