Benzodiazepine Tapering: Using Temazepam to Taper Off Clonazepam
Temazepam is not recommended for tapering off clonazepam (Klonopin) as long-acting benzodiazepines like diazepam provide better protection against withdrawal symptoms, including seizures and delirium. 1
Optimal Tapering Strategy
Preferred Medication for Tapering
- Long-acting benzodiazepines (diazepam, chlordiazepoxide) are the gold standard for managing benzodiazepine withdrawal 1
- Temazepam is a medium-duration benzodiazepine primarily used for short-term insomnia treatment, not for tapering 2
- The pharmacokinetic properties of temazepam make it less suitable than diazepam for a controlled, gradual taper
Recommended Tapering Schedule
- Gradual reduction of approximately 25% every 1-2 weeks is recommended by the American Academy of Family Physicians and the American College of Physicians 1
- For clonazepam specifically, a substitution to diazepam (approximately 10mg diazepam = 0.5mg alprazolam equivalent) followed by gradual reduction is preferred 1
- Tapering should ideally be completed within 6 months to prevent the withdrawal process from becoming the central focus of the patient's life 3
Risks of Inappropriate Tapering
Withdrawal Seizure Risk
- Abrupt discontinuation or rapid tapering of benzodiazepines can precipitate life-threatening withdrawal reactions, including seizures 4
- Withdrawal seizures have been reported with short, medium, and long-acting benzodiazepines when discontinued abruptly 5
- The severity of seizures ranges from a single episode to coma and death 5
Other Withdrawal Symptoms
- Common withdrawal symptoms include rebound insomnia, anxiety, irritability, tremors, and sweating 1
- More severe acute withdrawal signs include catatonia, convulsions, delirium tremens, depression, hallucinations, mania, psychosis, and suicidality 4
- Protracted withdrawal syndrome can persist beyond 4-6 weeks after initial withdrawal 4
Special Considerations
Risk Factors for Severe Withdrawal
- Higher doses and longer duration of use increase withdrawal risk 6
- Patients with polydrug use, history of withdrawal seizures, significant medical comorbidities, or unstable psychiatric conditions should be referred to specialists 1
- Concurrent use of benzodiazepines and opioids should be avoided due to risk of fatal overdose 1
Supportive Measures During Tapering
- Cognitive behavioral therapy significantly increases tapering success rates 1
- Relaxation techniques, sleep hygiene education, and support groups are beneficial for managing symptoms during tapering 1
- Patient education about risks and benefits of discontinuation is crucial for success 1
Common Pitfalls to Avoid
- Tapering too quickly: Increases risk of withdrawal symptoms and taper failure 1
- Using short-acting benzodiazepines for tapering: Provides less stable blood levels and greater risk of breakthrough symptoms 1
- Inconsistent dosing: Can lead to withdrawal symptoms 1
- Failing to address underlying conditions: Can lead to taper failure 1
If withdrawal symptoms become problematic during the taper, consider slowing the taper or temporarily returning to the previous dose before attempting a slower taper 1. The goal should be a successful, comfortable discontinuation that minimizes withdrawal symptoms while achieving freedom from benzodiazepine dependence.
