What is the best approach for a patient experiencing tinnitus while tapering off Klonopin (clonazepam)?

Benzodiazepine Withdrawal-Related Tinnitus Management

Slow the taper immediately and consider pausing at the current dose until tinnitus resolves, as tinnitus is a recognized protracted benzodiazepine withdrawal symptom that signals the need to further slow the taper rate. 1

Understanding the Symptom

Tinnitus is explicitly listed as a protracted benzodiazepine withdrawal symptom that can persist beyond 4-6 weeks after dose reduction 1. The FDA clonazepam label specifically identifies tinnitus among the protracted withdrawal syndrome symptoms, which may last weeks to more than 12 months 1. This is distinct from acute withdrawal and represents a more concerning sign that the taper is proceeding too rapidly for this patient's physiology.

Immediate Taper Adjustment

Pause or significantly slow the current taper schedule. 1, 2

• If tinnitus is mild and tolerable, reduce the taper rate to 0.25 mg every 2-4 weeks rather than weekly 2
• If tinnitus is moderate to severe or distressing, pause the taper entirely at the current dose until symptoms resolve 1
• The appearance of clinically significant withdrawal symptoms like tinnitus signals the need to further slow the taper rate 3
• For patients on long-term benzodiazepines (≥1 year), tapers of 10% per month or slower are better tolerated than rapid tapers 3

Evidence-Based Tapering Protocol

Use a gradual percentage-based reduction approach: 2

• Decrease by 0.25 mg per 2-week period (not per week) once below 1 mg daily 2
• Each new dose should be 90% of the previous dose, not a straight-line reduction 3
• A successful study demonstrated that clonazepam can be discontinued with mostly mild withdrawal symptoms using 0.25 mg/week reductions, but this patient clearly needs slower 2
• The taper may require several months to years depending on individual tolerance 3

Symptomatic Management

Address the tinnitus symptomatically while maintaining the slower taper: 3

• Consider gabapentin for short-term use to mitigate anxiety and irritability associated with withdrawal 3
• Trazodone (25-50 mg at bedtime) can help with insomnia and anxiety without adding another benzodiazepine 3
• Mirtazapine is another option that addresses both anxiety and sleep disturbance 3
• Avoid adding other potentially dependence-forming medications 3

Critical Monitoring

Follow up at least monthly, preferably more frequently during this symptomatic period: 3

• Assess whether tinnitus is improving, stable, or worsening 1
• Monitor for other protracted withdrawal symptoms: dysphoria, irritability, insomnia, anhedonia, anxiety 3, 1
• Document the patient's functional status and quality of life 3
• Ensure the patient understands this is a withdrawal symptom, not a new medical condition requiring extensive workup 3

Common Pitfalls to Avoid

Never abruptly discontinue or make major dose reductions in benzodiazepines - this can cause significant morbidity and even death, making sudden cessation inappropriate except in extreme circumstances like confirmed diversion 3, 1. The FDA explicitly warns that abrupt discontinuation can precipitate acute withdrawal reactions including seizures, which can be life-threatening 1.

Do not push through severe withdrawal symptoms - the goal is durability over rapidity of the taper 3. Forcing a predetermined schedule when the patient is symptomatic increases dropout rates and risk of relapse to higher doses 3.

Avoid misdiagnosing withdrawal as relapse or new illness - protracted withdrawal symptoms cannot be easily differentiated from chronic anxiety symptoms, but the temporal relationship to dose reduction is key 3, 4.

Patient Communication

Explain that tinnitus is an expected potential withdrawal symptom that will resolve with appropriate taper adjustment 1. Reassure the patient that slowing or pausing the taper is not failure but rather appropriate medical management 3. Many patients actually feel and function better after successful benzodiazepine tapering, but the process must be tolerable 3.

The target dose may not be zero - some patients benefit from stabilization at a lower maintenance dose rather than complete discontinuation 3.
