Pathway Overview
14 steps
Algorithm Steps
14 total
01Start 02Action 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
03Decision 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
04Warning 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
05Action 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
06Action 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)
07Action 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
08Warning ⚠️ 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)
09Action Phenobarbital Substitution
Alternative for refractory withdrawal
- Convert to phenobarbital equivalents
- 30mg phenobarbital = 10mg diazepam (rough)
- Load with phenobarbital, then taper
- Longer half-life = smoother taper
- Requires inpatient monitoring
10Action Psychological Support
Essential for successful discontinuation
- CBT for anxiety/insomnia
- Address underlying anxiety disorder
- Education about withdrawal course
- Support groups
- Regular follow-up visits
11Action Protracted Withdrawal Syndrome
Symptoms lasting weeks-months
- Anxiety, insomnia, cognitive issues may persist
- Gradual improvement over 6-18 months typical
- Not indication to restart benzodiazepines
- Reassurance and supportive therapy
- Treat symptoms with non-benzodiazepine options
12Outcome Successful Discontinuation
Long-term management
- Complete benzodiazepine cessation
- Alternative anxiety management strategies
- Relapse prevention
- Avoid benzodiazepines in future if possible
- Document history for future providers
13Action Adjunctive Medications
For symptom management during taper
- Carbamazepine/Gabapentin: Anti-seizure, anxiety
- Propranolol: Tremor, tachycardia
- Hydroxyzine: Anxiety (non-addicting)
- Trazodone/mirtazapine: Insomnia
- Avoid substituting with other controlled substances
- Path rejoins step 10Shared downstream outcome
14Action Outpatient Taper
Gradual reduction with monitoring
- Path rejoins step 05Shared downstream outcome
