  • Management
  • Benzodiazepine Taper Schedules
  1. Monitor every 1 to 2 weeks
  2. Calculate Diazepam to Benzodiazepine Equivalents
    1. See Benzodiazepine Equivalents
    2. Convert from short acting (e.g, Alprazolam) to long acting Benzodiazepines (e.g. Diazepam) at start of taper
  3. Protocol: Typical for on longterm prescribed Benzodiazepines
    1. Start at 50% of calculated Valium dose
    2. Reduce dose by 25% each week for the first 2 weeks, until 50%, then decrease dose by 12.5% every 4-7 days
    3. Decrease dose by no more than 5 mg Diazepam equivalents/week until <20 mg/week, then decrease by 1-2 mg/week
    4. Decrease Alprazolam by no more than 0.5 mg increments
      1. Alprazolam >=6 mg/day decrease by 0.5 mg every 2 to 3 weeks
      2. Alprazolam <= 2 mg/day decrease by 0.25 mg every 2 to 3 weeks
  4. Example: Rapid Taper for Detox in Benzodiazepine Abuse
    1. Alprazolam 6 mg is equivalent to 60 mg Diazepam
    2. Alprazolam 10 mg is equivalent to 100 mg Diazepam
    3. Start taper at 50% or 50 mg Diazepam per day
    4. Decrease dosing per Diazepam taper below
      1. Days 1-3: 10 mg orally three times daily (30 mg/day)
      2. Days 4-6: 5 mg orally four times daily (20 mg/day)
      3. Days 7-9: 5 mg orally three times daily (15 mg/day)
      4. Days 10-12: 5 mg orally twice daily (10 mg/day)
      5. Days 13-15: 5 mg orally daily (5 mg/day)
  5. Indications for slower taper (over 6 to 12 weeks)
    1. Alprazolam (esp. high dose >4 mg/day)
    2. Benzodiazepine use >2 to 3 months
    3. Seizure Disorder
    4. Panic Disorder
      1. Decrease dose by no more than 10% of dose weekly (typically over 2 to 7 months)
  6. Other adjunctive medications for Benzodiazepine Withdrawal symptoms
    1. Valproate
    2. Tricyclic Antidepressants
