How should I manage Xanax (alprazolam) withdrawal in an adult patient, including tapering protocol, conversion to a long‑acting benzodiazepine, and adjunctive treatments?

Managing Xanax (Alprazolam) Withdrawal

Alprazolam withdrawal must be managed with a gradual taper reducing the dose by 10–25% of the current dose every 1–2 weeks for short-term users (<1 year), or 10% per month for long-term users (≥1 year), with conversion to a long-acting benzodiazepine like diazepam strongly preferred due to alprazolam's high potency and short half-life that increase rebound and withdrawal severity. 1

Critical Safety Framework

Abrupt discontinuation of alprazolam can cause seizures and death—never stop suddenly. 1, 2 The FDA label explicitly warns that withdrawal symptoms including seizures have been reported after only brief therapy at doses within the recommended range (0.75–4 mg/day), and the risk of withdrawal seizures increases at doses above 4 mg/day. 2

Benzodiazepine withdrawal carries greater risks than opioid withdrawal and must always be conducted gradually. 1 If a patient is taking both opioids and benzodiazepines, taper the benzodiazepine first due to higher withdrawal risks. 1

Pre-Taper Assessment

Before initiating any taper, assess for: 1

• History of withdrawal seizures (requires immediate specialist referral)
• Concurrent substance use disorders (refer to specialist)
• Unstable psychiatric comorbidities (requires specialist involvement)
• Current dose and duration of use (determines taper speed)
• Check the Prescription Drug Monitoring Program to identify all controlled substances the patient is receiving 1

Recommended Tapering Protocol

Option 1: Direct Alprazolam Taper (Less Preferred)

For patients on alprazolam less than 1 year: 1

• Reduce by 10–25% of the current dose every 1–2 weeks
• Example: 2 mg/day → 1.5 mg/day (25% reduction) for weeks 1–2, then → 1.1–1.2 mg/day (20–25% of current dose) for weeks 3–4

For patients on alprazolam more than 1 year: 1

• Reduce by 10% of the current dose per month
• Example: 2 mg/day → 1.8 mg/day (10% reduction) month 1, then → 1.6 mg/day (10% of 1.8 mg) month 2

Critical principle: Always reduce by a percentage of the current dose, not the original dose, to prevent disproportionately large final reductions. 1

Option 2: Conversion to Diazepam Then Taper (Strongly Preferred)

Diazepam is preferred for tapering because its longer half-life provides more protection against seizures and withdrawal symptoms. 1 Research demonstrates that chlordiazepoxide substitution at a ratio of 50 mg per 1 mg alprazolam (or 25 mg in elderly) allows rapid, well-tolerated withdrawal. 3

Conversion protocol: 1, 3

1. Convert alprazolam to equivalent diazepam dose using a gradual cross-taper
2. Typical conversion: 1 mg alprazolam ≈ 10 mg diazepam
3. Reduce alprazolam by 10–25% while simultaneously introducing diazepam at equivalent dosing
4. Once fully converted to diazepam, taper diazepam by 10–25% of current dose every 1–2 weeks (short-term use) or 10% per month (long-term use)

Managing Withdrawal Symptoms

Monitor for withdrawal symptoms at every visit: anxiety, tremor, insomnia, sweating, tachycardia, headache, weakness, muscle aches, nausea, confusion, and seizures. 1 The FDA label notes that withdrawal can include abdominal and muscle cramps, vomiting, and convulsions. 2

Clinically significant withdrawal symptoms signal the need to slow the taper rate or pause entirely. 1 Maintain the current dose for 2–4 weeks while optimizing supportive measures before resuming the taper. 1

Adjunctive Pharmacological Support

Gabapentin can mitigate withdrawal symptoms: 1

• Start 100–300 mg at bedtime or three times daily
• Increase by 100–300 mg every 1–7 days as tolerated
• Adjust dose in renal insufficiency
• Titrate cautiously to avoid dose-dependent dizziness and sedation

Other adjunctive options: 1

• Carbamazepine may help, though it can affect alprazolam metabolism
• Pregabalin has shown potential benefit
• SSRIs (particularly paroxetine) may manage underlying anxiety during tapering
• Trazodone 25–200 mg for short-term insomnia management

For muscle aches: NSAIDs or acetaminophen 1

Non-Pharmacological Interventions (Essential)

Cognitive-behavioral therapy (CBT) during the taper significantly increases success rates and should be incorporated. 1, 4 Research shows that CBT targeting avoidance behaviors (skipping events, alcohol use, benzodiazepine reliance) improves taper success and reduces relapse. 1

Additional supportive measures: 1

• Mindfulness and relaxation techniques
• Sleep hygiene education
• Exercise and fitness training
• Patient education about benzodiazepine risks and benefits of tapering

Monitoring Requirements

Follow up at least monthly during the taper, with more frequent contact during difficult phases. 1 Monitor for: 1

• Withdrawal symptoms and their severity
• Depression, anxiety, and suicidal ideation
• Substance use disorders that may emerge
• Functional decline (inability to maintain daily activities)

Advise patients of increased overdose risk if they return to previous doses after tolerance is lost. 1

When to Pause the Taper

Pause the taper when: 1

• Clinically significant withdrawal symptoms emerge (anxiety, tremor, insomnia, sweating, tachycardia)
• Severe psychological distress (depression, panic attacks, suicidal ideation)
• Functional decline (patient cannot maintain daily activities)

Restart criteria after pause: 1

• Withdrawal symptoms have resolved or returned to baseline
• Patient expresses readiness
• Supportive measures are optimized
• Restart at the same dose where the pause occurred—never increase

Special Populations

Elderly Patients

• Use lower doses and more gradual tapers 1
• Consider 10% reduction per month regardless of duration of use
• Alprazolam is particularly inappropriate for elderly due to high potency, rapid onset, and association with cognitive impairment, falls, and fractures 1

Pregnant Patients

Do not taper benzodiazepines during pregnancy without specialist consultation—withdrawal can cause spontaneous abortion and premature labor. 1

Hepatic Dysfunction

Patients with liver disease require extra caution with dose adjustments and may benefit from specialist consultation. 1

Mandatory Specialist Referral

Refer immediately to a specialist for: 1

• History of withdrawal seizures
• Unstable psychiatric comorbidities
• Co-occurring substance use disorders
• Previous unsuccessful office-based tapering attempts

Expected Timeline and Realistic Goals

The taper will likely take 6–12 months minimum, possibly longer. 1 Research shows that even a 10% reduction every 3 days resulted in only 24% of patients completing withdrawal successfully. 1

Both complete discontinuation and attainment of a reduced, functionally acceptable dose are considered acceptable outcomes. 1 Maintenance therapy is a legitimate outcome for patients who cannot complete tapering—never abandon the patient. 1

Critical Pitfalls to Avoid

• Never taper too quickly—research shows gradual 8-week tapers are superior to 4-week tapers for alprazolam 5, 6
• Never use straight-line percentage reductions from the starting dose—this subjects patients to disproportionately large final decrements 1
• Never abandon the patient even if tapering is unsuccessful—maintain the therapeutic relationship and consider maintenance therapy 1
• Never add new psychotropic medications during taper when current symptoms are manageable 1
• Never prescribe additional CNS depressants during the tapering period 1

Distinguishing Withdrawal from Recurrence

The FDA label notes that distinguishing between withdrawal symptoms and recurrence of illness is often difficult. 2 Key differences: 2

• Withdrawal syndrome: New symptoms, appears toward end of taper or shortly after discontinuation, decreases with time
• Recurrence: Symptoms similar to pre-treatment, may occur early or late, persist over time

Research confirms that 27% of alprazolam-treated patients experience rebound panic attacks during taper, and 35% experience a distinct withdrawal syndrome. 5 However, both typically subside by the second week post-discontinuation. 5
