What is the recommended taper schedule for clonazepam (Klonopin)?

Recommended Clonazepam (Klonopin) Tapering Schedule

For patients taking clonazepam, the recommended tapering approach is to reduce the dose by 10% of the most recent dose every 2-4 weeks, with slower tapers of 10% per month or less for long-term users (≥1 year). 1

General Tapering Principles

• Tapering should be individualized based on duration of use, with longer-term users requiring slower tapers to minimize withdrawal symptoms 2, 1
• Patient agreement and involvement in the tapering plan significantly improves success rates 2, 1
• For most patients, reducing by 10% of the most recent dose (not the original dose) every 2-4 weeks provides a balance between progress and tolerability 1, 3
• Long-term users (≥1 year) may require much slower tapers of 10% per month or less 2, 1

Specific Clonazepam Tapering Protocol

• For patients on clonazepam, research supports reducing the dose by 0.25 mg per week after reaching 1 mg daily 4
• For higher doses, begin with reductions of 0.5 mg every 2 weeks until reaching 1 mg daily, then slow to 0.25 mg weekly reductions 4
• Example: For a patient on 2 mg daily
  • Weeks 1-2: Reduce to 1.5 mg daily
  • Weeks 3-4: Reduce to 1 mg daily
  • Week 5: Reduce to 0.75 mg daily
  • Week 6: Reduce to 0.5 mg daily
  • Week 7: Reduce to 0.25 mg daily
  • Week 8: Discontinue 4

Monitoring and Management

• Monitor patients at least monthly during the tapering process 2, 1
• Watch for withdrawal symptoms including anxiety, insomnia, tremor, sweating, tachycardia, nausea, and headache 2, 4
• If withdrawal symptoms become severe, return to the previous well-tolerated dose and slow the taper further 2, 1
• Consider adjunctive medications for specific withdrawal symptoms:
  • α2-agonists like clonidine or tizanidine for autonomic symptoms 2, 1
  • Trazodone, gabapentin, or mirtazapine for short-term management of insomnia or anxiety 2

Special Considerations

• Never abruptly discontinue clonazepam except in cases of confirmed diversion or serious medical toxicity 2, 1
• Patients with seizure disorders require even slower tapers to prevent withdrawal seizures 3
• For patients also taking opioids, consider tapering the benzodiazepine first 3
• Incorporate non-pharmacological approaches during tapering:
  • Cognitive behavioral therapy for anxiety management 1, 3
  • Stress reduction techniques and physical activity 3

Common Pitfalls to Avoid

• Tapering too quickly (faster than 10% reduction every 2-4 weeks) increases withdrawal risk 1
• Setting arbitrary time limits for completing the taper often leads to failure 1
• Failing to pause the taper when patients experience significant withdrawal symptoms 2, 1
• Not prescribing the lowest available dose before complete discontinuation 5

Follow-up Recommendations

• If the taper becomes difficult, consider pausing at the current dose rather than abandoning the patient or the tapering plan 2, 3
• Educate patients about increased risk of overdose if returning to previous higher doses 2, 3
• Continue monitoring for several months after complete discontinuation to assess for recurrence of underlying conditions versus withdrawal symptoms 2, 1
