- Design
- Population-level observational study of national prescribing and ADR data
- Population
- 14 benzodiazepines prescribed in England, 2020–2025
- Primary outcome
- Prescribing rate trends, costs and fatality ratios
- Effect
- −4.3% per year (95% CI −4.5 to −4.03); clobazam +6.36% per year
This national observational study analysed prescribing, cost and adverse-reaction reports for 14 benzodiazepines in England. It was published in the British Journal of Clinical Pharmacology in September.
Prescribing fell from 15,562 to 12,284 items per 100,000 population between 2020 and 2025, a mean annual change of −4.3%, driven by diazepam, temazepam and chlordiazepoxide. Clobazam rose by 6.4% a year. The average fatality ratio among adverse-reaction reports was 4.5 per 100, highest for oxazepam (17.9), lorazepam (9.1) and alprazolam (8.6). Ethnicity modified deprivation-related prescribing patterns.
Fatality ratios from spontaneous reports reflect what gets reported, not the true risk per prescription, so they cannot rank drugs by danger. The trend shows sustained deprescribing in primary care is achievable.
- Review every long-term benzodiazepine prescription for a taper plan.
- Taper gradually, typically 10–25% of the dose every 2–4 weeks, slower near the end.
- Avoid starting short-acting agents such as alprazolam for anxiety.
- Check for co-prescribed opioids or gabapentinoids.
Why it matters
It shows population-level benzodiazepine reduction is achievable in primary care.
Don't overread it
Spontaneous-report fatality ratios do not show which benzodiazepine is most dangerous per prescription.
The statistics, in plain English
Fatality ratios here are deaths among reported adverse reactions, a number shaped by reporting habits and case severity. They are not death rates per patient treated and should not be compared directly between drugs.
