Alprazolam (Xanax) is among the most prescribed benzodiazepines but also among the most difficult to stop. Its short half-life (~11 hours) produces rapid drug level changes and intense interdose withdrawal. How to taper off alprazolam typically requires switching to a longer-acting benzodiazepine and slow tapering. Cold turkey is dangerous and can cause seizures. Always work with your prescriber.
Why alprazolam is difficult
- Short half-life produces interdose withdrawal symptoms
- High potency requires precise tapering
- Rapid onset/offset increases addiction potential
- Long-term users develop physical dependence quickly
Switching to diazepam
Standard approach for difficult alprazolam tapers — switch to longer-acting diazepam (Valium, half-life 20-100+ hours):
- Approximate equivalence: 1 mg alprazolam = 20 mg diazepam
- Switch over 1-2 weeks
- Stabilize on diazepam
- Taper diazepam slowly (much easier than alprazolam)
The Ashton manual provides detailed guidance for benzo conversions and tapering. See our Ashton method guide.
Direct alprazolam tapering
If staying on alprazolam:
- Reduce by 0.25-0.5 mg every 1-2 weeks
- Slower at lower doses (0.25 mg cuts at low end)
- Use 0.25 mg tablets for precise dosing
- Total duration: months
Withdrawal symptoms
- Severe anxiety, panic
- Insomnia
- Tremor
- Sweating, autonomic effects
- Sensory hypersensitivity
- Cognitive issues
- Seizures (cold turkey or rapid taper)
Seizure risk
Benzodiazepine withdrawal seizures can be fatal. Risk factors:
- Long-term use
- High doses
- Prior seizure history
- Cold turkey or rapid taper
Medical supervision is essential.
Frequently Asked Questions

Discuss with prescriber. Some medications complicate tapering.
The bottom line on tapering off alprazolam
Alprazolam tapering requires slow approach with medical supervision. Switching to diazepam first is often beneficial. Cold turkey is dangerous. The Ashton manual provides detailed guidance. Plan months for the full process. Discuss with prescriber experienced in benzo tapering.
