From the Guidelines
A recommended taper regimen for a patient taking Diazepam 5mg three times a day (TID) is to reduce the dose by 25% every 1–2 weeks, as this approach has been used safely and with moderate success 1. To implement this taper, start by calculating 25% of the total daily dose, which for Diazepam 5mg TID (15mg total daily dose) would be 3.75mg.
- Begin the taper by reducing the daily dose by 3.75mg, which could be achieved by decreasing one of the daily 5mg doses to 1.25mg (5mg - 3.75mg = 1.25mg), while keeping the other two doses at 5mg, resulting in a new daily dose of 11.25mg.
- After stabilizing at this new dose for 1-2 weeks, reduce another daily dose by 3.75mg, following the same pattern until the patient is taking a significantly lower dose.
- The final stages of the taper should be slower, possibly reducing by only 1.25mg at a time, to minimize the risk of withdrawal symptoms.
- Throughout the taper, monitor for withdrawal symptoms such as anxiety, insomnia, irritability, tremors, or increased heart rate, and adjust the taper schedule as needed 1.
- If withdrawal symptoms become significant, temporarily pause the taper until symptoms subside before continuing with a more gradual reduction. This approach is supported by the contextual evidence review, which emphasizes the importance of gradual tapering to avoid rebound anxiety, hallucinations, seizures, delirium tremens, and, in rare cases, death associated with abrupt benzodiazepine withdrawal 1.
From the Research
Diazepam Taper Regimen
- A recommended taper regimen for a patient taking Diazepam 5mg three times a day (TID) is not explicitly stated in the provided studies, but general guidelines for benzodiazepine tapering can be applied 2, 3.
- Benzodiazepine dose tapering can be done faster in a hospital setting in high-dose abusers, but must be done more slowly in the outpatient setting in therapeutic dosage users 2.
- A symptom-triggered taper method, where diazepam is administered only in response to withdrawal symptoms, can be as effective as a fixed dose taper method for in-patient benzodiazepine withdrawal treatment 3.
Considerations for Tapering
- The severity of withdrawal symptoms and the patient's individual response to tapering should be closely monitored 2, 3.
- Tapering should be done gradually to minimize the risk of withdrawal seizures and other complications 2.
- The use of diazepam, with its long elimination half-life, can result in a smoother withdrawal with a lower incidence and severity of breakthrough symptoms and rebound phenomena 4.
Clinical Evidence
- Studies have shown that diazepam can be safely used for the treatment of alcohol withdrawal in patients with liver disease and elderly patients when administered using a simple symptom-based approach 4.
- Diazepam has been found to be effective in the treatment of anxiety and insomnia, but long-term use can lead to tolerance, dependence, and withdrawal effects 5.
- A loading dose of diazepam can be used to simplify the treatment of alcohol withdrawal, taking advantage of the kinetic tapering afforded by the drug's long half-life and its metabolites 6.
