FRANZCPMRCPsychABPNMD-DNBNEET-SS

Red flags

  • Abrupt cessation after continuous benzodiazepine use — seizure, delirium, and severe rebound risk; reinstate cover then controlled taper
  • Concurrent benzodiazepines with opioids or heavy alcohol — synergistic CNS and respiratory depression and overdose death
  • Automatic long-term renewals for primary anxiety or insomnia without written exit plan or non-GABAergic treatment
  • Flumazenil as default in chronic users or mixed overdose — can precipitate seizures; highly selected use only
  • Default high-potency short-acting alprazolam for chronic anxiety — interdose rebound and hard taper
  • Using buspirone or antidepressants alone as acute GABA withdrawal cover — they do not replace benzodiazepine PAM activity

The one-line answer

Prescribe a benzodiazepine only with a named indication, the lowest effective oral dose, the shortest duration, and a written exit plan on day one. When continuous use is already established, convert high-potency short-acting agents to a long-acting vehicle (often diazepam equivalents) and reduce about 10–25% every 1–2+ weeks (slower near the end), while treating the underlying anxiety or insomnia with non-GABAergic care and never stacking opioids casually.[1][2][12][14][17]

Meet the patient

A 68-year-old retired teacher brings her repeat prescriptions to clinic in a plastic bag. Temazepam 10 mg nocte, started for grief eleven years ago by a locum nobody can name. Two falls this year, one with a wrist fracture. She has never once taken more than she was told to take.[2][9][10][19]

She reads the referral letter upside down on your desk. It says "benzodiazepine dependence", and she starts to cry, because she believes that phrase means she is an addict.[1][3]

Two questions are now live, and examiners ask both: whose prescribing produced this? and how do you get her off it without harming her? Everything below answers those two.[8][14]

This leaf is prescribing craft and taper craft. Use-disorder nosology and dual-diagnosis depth live in the benzodiazepine-dependence topic; the wider non-GABAergic class map (buspirone, pregabalin, Z-drugs, melatonin) lives in anxiolytics and hypnotics. What you must be able to do here is initiate safely, convert equipotently, deprescribe in evidence language, and refuse the classic traps.[1][8][15]
