One common issue on consult service is patients taking chronic benzodiazepines. A few practical principles are helpful when thinking about tapering.
1️⃣ Short-Term Use
Patients on a benzodiazepine (except alprazolam) for:
- < 1 month
- At manufacturer-recommended doses
- Example: Lorazepam 2–6 mg/day
Usually do not require a taper.
2️⃣ Longer-Term Use at Standard Doses
Patients on a benzodiazepine (except alprazolam) for:
- > 1 month
- At manufacturer-recommended doses
➡️ Can typically be tapered over ~4 weeks as an outpatient. Reduce by 25% q2week, may slow down to 12.5% q2weeks closer to stopping if needed.
If Inpatient, can reduce by up to 10mg diazepam equivalents per day with CIWA monitoring
However:
- Some patients may require much slower tapers
- tapering may be months to 1+ year
3️⃣ Very High-Dose
Approximately ≥ 100 mg diazepam equivalents per day
If taken for several months, these patients are:
- At highest risk for severe withdrawal
- At risk for seizures, delirium, autonomic instability
Inpatient management is recommended
Approach:
- Convert to a long-acting benzodiazepine (e.g., diazepam)
- Rationale:
- Smoother taper
- Less rebound anxiety
- Less severe withdrawal
- Lower dropout rates
- Taper the long-acting agent by approximately 10% per day inpatient
- Monitor closely for withdrawal symptoms and seizures
***Special Note: Alprazolam
Alprazolam is different because:
- Short half-life
- Higher rebound anxiety
- Less predictable cross-coverage when switching to long-acting agents
If patients do not tolerate conversion to a long-acting benzodiazepine: You may need to switch back to alprazolam and taper directly.
