Lorazepam 0.25 mg BID Taper Schedule
For lorazepam 0.25 mg twice daily (total daily dose 0.5 mg), reduce the dose by 25% every 1-2 weeks, which translates to decreasing by 0.125 mg (one-eighth of a milligram) every 1-2 weeks until discontinuation. 1, 2
Specific Taper Protocol
Week-by-week reduction:
- Weeks 1-2: 0.25 mg in AM, 0.125 mg in PM (total 0.375 mg/day)
- Weeks 3-4: 0.125 mg twice daily (total 0.25 mg/day)
- Weeks 5-6: 0.125 mg once daily (total 0.125 mg/day)
- Week 7: Discontinue
This represents a 4-6 week taper for this relatively low dose. The FDA label explicitly recommends gradual tapering to reduce withdrawal risk 3, and the 25% reduction every 1-2 weeks is the most commonly cited evidence-based schedule that has been "used safely and with moderate success" 1, 2.
Critical Implementation Details
Dose preparation: At these low doses, you'll need either:
- Liquid formulation (lorazepam oral concentrate) for precise dosing 3
- Tablet splitting (though 0.125 mg requires splitting 0.25 mg tablets in half)
- Compounded formulations for very small final doses 4, 5
Monitoring frequency: Follow up at least every 2 weeks during the taper 6. More frequent contact (weekly phone calls or visits) may be needed if withdrawal symptoms emerge.
Withdrawal Symptom Management
Watch for: Anxiety, insomnia, irritability, tremor, diaphoresis, tachycardia, and in severe cases (rare at this dose), seizures 3.
If withdrawal symptoms occur:
- Pause the taper at the current dose until symptoms resolve 6, 3
- Consider reverting to the previous dose if symptoms are severe 5
- Slow the taper rate (e.g., reduce by 10% every 2-4 weeks instead) 6
Adjunctive support:
- Cognitive behavioral therapy significantly increases taper success 1, 2
- Address underlying anxiety with evidence-based psychotherapy or non-benzodiazepine medications (SSRIs, SNRIs, buspirone) 1, 2
- Short-term use of trazodone, gabapentin, or mirtazapine may help with insomnia/anxiety during taper 7
Important Caveats
Slower may be necessary if:
- Duration of use >1 year: Consider 10% monthly reductions instead 6
- Patient has history of failed tapers: Use hyperbolic (proportional) reductions rather than linear 4, 5
- Elderly or debilitated patients: May need even slower taper 3
Concurrent opioid use: If the patient is also on opioids, taper the opioids FIRST before addressing benzodiazepines, as benzodiazepine withdrawal carries greater risk (including seizures) 1, 2. The combination quadruples overdose death risk 2, 3.
Protracted withdrawal: Some patients experience anxiety, insomnia, or dysphoria for weeks to months after discontinuation 7, 3. This should be anticipated, discussed beforehand, and managed with non-pharmacologic strategies and non-benzodiazepine medications.
Patient agreement: Obtain informed consent using a written taper agreement that outlines the schedule, withdrawal risks, management strategies, and provisions for taper failure 8.
The evidence strongly supports that abrupt discontinuation is dangerous and should never be attempted 3. Even at this low dose of 0.5 mg/day total, gradual reduction over 4-8 weeks minimizes withdrawal risk while maintaining safety.
