Algorithm Steps

1. ▶

   Start

   Benzodiazepine Withdrawal/Taper

   Patient requiring benzodiazepine discontinuation

   1. ●

      Action

      Assess Dependence & Risk

      Evaluate physical dependence and withdrawal risk

      • Duration of use (>4 weeks = physical dependence likely)
      • Daily dose (higher = higher risk)
      • Type of benzodiazepine (short-acting = more severe withdrawal)
      • History of seizures
      • History of severe withdrawal
      • Concurrent alcohol/substance use
      • Psychiatric comorbidities
      1. ◆

         Decision

         Appropriate Setting?

         Inpatient vs. Outpatient

         • INPATIENT if: High-dose long-term use, prior seizures, prior severe withdrawal, polysubstance use, medical/psychiatric instability, poor social support
         • OUTPATIENT if: Lower dose, stable, reliable support, no prior complications
         1. ⚠

            Warning

            Inpatient Withdrawal

            Medical supervision required

            • Daily dose >40mg diazepam equivalent
            • History of withdrawal seizures
            • Concurrent alcohol withdrawal
            • Medical comorbidities
            • Unable to comply with outpatient taper
            1. ●

               Action

               Convert to Long-Acting Benzodiazepine

               Switch to diazepam or chlordiazepoxide

               • Diazepam preferred (long half-life, smoother taper)
               • Equivalents (approximate):
               • Alprazolam 0.5mg = Diazepam 5mg
               • Lorazepam 1mg = Diazepam 5mg
               • Clonazepam 0.5mg = Diazepam 10mg
               • Divide into 3-4 daily doses initially
               1. ●

                  Action

                  Establish Taper Schedule

                  Gradual dose reduction

                  • Standard: 10% reduction every 1-2 weeks
                  • Slower: 5% every 2-4 weeks (for long-term users)
                  • Faster: 10-25% weekly (inpatient, short-term use)
                  • Hold/slow taper if significant withdrawal symptoms
                  • Last portion often slowest (hardest to discontinue)
                  1. ●

                     Action

                     Monitor for Withdrawal

                     Recognize symptoms early

                     • EARLY: Anxiety, insomnia, irritability, tremor, sweating
                     • MODERATE: Palpitations, muscle tension, headache, nausea
                     • SEVERE: Seizures, psychosis, delirium
                     • Symptoms peak 2-4 days for short-acting, 4-7 days long-acting
                     • Use CIWA-B or similar scale for inpatient
                     1. ⚠

                        Warning

                        ⚠️ Severe Withdrawal

                        Medical emergency

                        • Seizures: Lorazepam 2-4mg IV/IM
                        • Delirium: ICU admission
                        • Return to previous dose and slow taper
                        • Consider phenobarbital substitution protocol
                        • Flumazenil contraindicated (precipitates seizures)
                        1. ●

                           • Load with phenobarbital, then taper
                           • Longer half-life = smoother taper
                           • Requires inpatient monitoring
