How Do You Taper Long-Term Benzodiazepines in Older Adults?

Quick answer

Most older adults on long-term benzodiazepines can successfully taper. Switch short-acting agents (alprazolam, lorazepam) to a diazepam or clonazepam equivalent, then reduce 10–25% every 2–4 weeks, slowing the last 25% further. The EMPOWER trial showed a patient-focused educational letter doubled 6-month cessation rates. Do not abruptly stop — seizure and delirium risk is real.

EMPOWER (2014)

PMID 24733354

303 community-dwelling adults ≥65 on chronic benzodiazepine

Patient educational letter (direct-to-consumer deprescribing) — 27% discontinuation at 6 months vs 5% usual care (RR 5.5, 95% CI 2.4–12.3).

Consensus review

Benzodiazepines listed as 'avoid' in elderly due to cognitive impairment, falls, and delirium. Taper when clinically feasible.

Practical decision algorithm

IfThen
Short-acting benzodiazepine (alprazolam, lorazepam, temazepam)Convert to diazepam equivalent using a published conversion table (commonly cited Ashton Manual: alprazolam 0.5 mg ≈ diazepam 10 mg; lorazepam 1 mg ≈ diazepam 10 mg). Verify with your institution's preferred reference; equivalencies are approximate.
Low-moderate dose (≤10 mg diazepam eq.), cognitively intactReduce 1–2 mg diazepam eq. every 2 weeks. Slow the last 25%.
High-dose (>20 mg diazepam eq.) or long duration (>5 years)Consider inpatient/structured outpatient taper; 5–10% reduction every 2–4 weeks. CBT-I for sleep.
Taper withdrawal symptoms (anxiety, tremor, insomnia)Slow by 50% or pause taper. Do not restart original dose unless severe.
Rebound anxietyAdd SSRI (sertraline), CBT, or hydroxyzine PRN. Do not add an alternative benzodiazepine.

Guideline position

AGS Beers Criteria 2023: benzodiazepines potentially inappropriate in ≥65. Choosing Wisely (AGS): avoid benzodiazepines for insomnia, agitation, or delirium in older adults. Canadian deprescribing.org: structured 6-month taper protocols.

Contraindications and cautions

  • Active alcohol withdrawal or severe DTs — continue benzodiazepine
  • Refractory seizure disorder on benzodiazepine
  • End-of-life comfort care
  • Patient with severe unstable psychiatric illness (e.g., catatonia on benzo)

Frequently asked questions

What is the seizure risk in gradual taper?
Near zero with 10–25% reductions every 2–4 weeks. Abrupt stops at high doses carry 20–30% seizure risk; graduated tapering reduces this to <1%.
Is diazepam substitution always necessary?
Not always. Patients on stable low-dose lorazepam can often taper the original agent directly. Substitution helps when peak-trough symptoms dominate or the short-acting agent has been difficult to reduce.
How long does full taper take?
Low-dose, short-duration: 6–12 weeks. High-dose or long-duration: 6–12 months. Slower at the end (the last 25% is the hardest).
Can CBT-I replace benzodiazepine for insomnia?
Yes — first-line per AASM. CBT-I has equal or better efficacy and no withdrawal risk. VA and many health systems offer digital CBT-I.
What about Z-drugs (zolpidem, eszopiclone)?
Also on Beers list — similar cognitive and fall risks. Taper with similar protocols. Zolpidem has shorter half-life; taper by 25% every 2 weeks.
