From the Guidelines
Safely tapering a patient off benzodiazepines requires a gradual reduction in dose by 10-25% every 1-2 weeks, with slower reductions as the dose gets lower, under medical supervision. This approach is supported by the most recent and highest quality study, which emphasizes the importance of a gradual tapering schedule to minimize the risk of withdrawal symptoms 1. The study suggests that a reduction of 25% of the daily benzodiazepine dose each week can be effective, but notes that withdrawal should often be more gradual, considering the desirable end point.
Key Considerations for Tapering Benzodiazepines
- Gradual tapering approach to minimize withdrawal symptoms
- Reduction in dose by 10-25% every 1-2 weeks
- Slower reductions as the dose gets lower
- Medical supervision throughout the tapering process
- Monitoring for withdrawal symptoms such as anxiety, insomnia, irritability, and seizures
Adjunctive Therapies to Support Tapering
- Cognitive-behavioral therapy (CBT) to increase tapering success rates
- Anti-depressants or other nonbenzodiazepine medications approved for anxiety
- Adjunctive medications like propranolol for physical symptoms or trazodone for sleep
Importance of Gradual Tapering
The gradual approach is necessary because benzodiazepines cause neuroadaptation in GABA receptors, and abrupt discontinuation can lead to dangerous withdrawal symptoms including seizures and delirium 1. A study published in the Mayo Clinic Proceedings in 2021 found that a gradual withdrawal strategy is recommended to minimize potential discontinuation effects, and that withdrawal should be gradual, in most cases extending over a period of greater than 1 month 1.
From the FDA Drug Label
To reduce the risk of withdrawal reactions, use a gradual taper to discontinue clonazepam or reduce the dosage (a patient-specific plan should be used to taper the dose) Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages, and those who have had longer durations of use. Do not stop taking this medication abruptly or decrease the dose without consulting your physician, since withdrawal symptoms can occur In all cases, it is important that your physician help you discontinue this medication in a careful and safe manner to avoid overly extended use of alprazolam tablets.
The safest method to taper a patient off benzodiazepines without precipitating withdrawal symptoms is to use a gradual taper. A patient-specific plan should be used to taper the dose. It is essential to consult a physician before stopping or decreasing the dosage of benzodiazepines, as withdrawal symptoms can occur. Patients taking higher dosages or those with longer durations of use are at an increased risk of withdrawal adverse reactions. Physicians should help patients discontinue the medication in a careful and safe manner to avoid extended use and potential withdrawal reactions 2 3.
- Key considerations:
- Gradual taper
- Patient-specific plan
- Consult a physician before stopping or decreasing the dosage
- Monitor for withdrawal symptoms
- Increased risk for patients taking higher dosages or with longer durations of use
From the Research
Tapering Methods
- Gradual tapering of benzodiazepines is recommended to minimize withdrawal symptoms 4, 5, 6, 7, 8
- The rate of tapering can vary, but a common approach is to reduce the dose by 25% per week 4, 8 or 0.25 mg per week for clonazepam 5
- For high-dose withdrawal, a rate of 10% per day is suggested, with patients being tolerance tested with diazepam and tapered off as inpatients 6
- Substitution of diazepam for another benzodiazepine can be helpful, as diazepam is available in a liquid formulation 7
Adjunctive Therapies
- Carbamazepine may have promise as an adjunctive drug therapy for benzodiazepine withdrawal syndrome, particularly in patients receiving high doses of benzodiazepines 4, 7
- Antidepressants can help if the patient is depressed before withdrawal or develops a depressive syndrome during withdrawal 7
- Psychological interventions, such as cognitive-behavioral therapy (CBT) and group therapy, can be effective in supporting patients during the withdrawal process 7
Predictors of Withdrawal Severity
- Personality factors, such as high Eysenck neuroticism, female sex, and mild-to-moderate alcohol use, can contribute significantly to the patient's difficulties with gradual benzodiazepine discontinuation 8
- Baseline personality and daily benzodiazepine dose or benzodiazepine half-life are not as significant predictors of withdrawal severity as previously thought 8
