Benzodiazepine detox is the medical process of safely tapering off benzodiazepines — a class of medications including alprazolam (Xanax), clonazepam (Klonopin), diazepam (Valium), and lorazepam (Ativan). Like alcohol, benzodiazepines act on the GABA system, and stopping abruptly after sustained use can produce seizures and, in severe cases, a life-threatening withdrawal syndrome.
The right way to detox from benzodiazepines is almost never abrupt. Even in medical settings, the protocol is a structured taper — gradually reducing the dose over weeks to months, often after first switching from a short-acting benzodiazepine (Xanax) to a long-acting one (Valium or Librium) that produces smoother blood levels and a more tolerable taper. SILC Health's medical benzo detox provides the structure, monitoring, and adjunct medications to do this safely.
Why medical detox
Why not just at home.
Benzodiazepines and alcohol are the two drug classes where unsupervised withdrawal can kill someone. The mechanism is the same — both work on GABA receptors, and abrupt removal of either creates dangerous central nervous system hyperexcitability. Grand mal seizures, severe blood pressure instability, and a delirium-like state are all on the table without a proper taper.
Beyond the medical danger, benzodiazepine withdrawal is one of the longest and most psychologically grueling. Post-acute symptoms (anxiety, insomnia, sensory sensitivity, depersonalization) can persist for months. Medical detox addresses the acute risk; ongoing care addresses the longer arc. Doing this at home rarely works — the symptoms drive most people back to a dose to get relief, and the protracted timeline benefits enormously from clinical structure.
Timeline
What withdrawal looks like.
Day 1 (short-acting) to Day 3 (long-acting)
Onset
- Anxiety, restlessness
- Insomnia
- Heightened sensitivity to light, sound, touch
- Sweating, tremor
- Loss of appetite
Days 2–7
Peak risk window
- Seizure risk (highest at this window)
- Severe anxiety, panic
- Blood pressure spikes
- Insomnia worsens
- Possible perceptual disturbances
Weeks 2–4
Acute taper
- Physical symptoms steadily improve with proper taper
- Anxiety, mood lability, insomnia continue
- Long-acting benzodiazepine taper continues stepwise
Months 1–12+
Post-acute withdrawal (PAWS)
- Sleep, mood, and anxiety can remain unstable
- Sensory hypersensitivity in some people
- Strongly improved by therapy, structure, and time
Medications
What we use, and why.
Long-acting benzodiazepine taper (diazepam or chlordiazepoxide)
Brand: Valium · Librium
The taper itself uses a long-acting benzodiazepine, producing smoother blood levels and a more tolerable reduction than tapering a short-acting drug like alprazolam directly. The dose is reduced incrementally over weeks to months depending on starting dose and duration of use.
Anticonvulsants (gabapentin, carbamazepine)
Reduce seizure risk and help manage anxiety and irritability during taper. Often continued through the post-acute window.
Adjunct anxiety / sleep medications
Buspirone, hydroxyzine, prazosin, or other non-benzodiazepine options for managing acute anxiety, insomnia, and autonomic symptoms.
Beta-blockers (propranolol)
Control elevated heart rate, blood pressure, and tremor during the acute window.
Our Approach
How SILC handles benzodiazepines detox.
SILC Health's medical benzodiazepine detox starts with a thorough assessment — which benzodiazepine, daily dose, duration of use, history of seizures, co-occurring conditions (chronic anxiety, sleep disorder, PTSD), and what other substances are involved. A taper plan is then built specifically for the case. Short-acting benzodiazepines (Xanax especially) are typically converted to a long-acting equivalent first, because the smoother pharmacokinetics make the taper substantially more tolerable.
The 24/7 medical setting is essential during the first 7–14 days. Vitals are monitored, anticonvulsants prevent breakthrough seizures, and the taper rate is adjusted based on how you're tolerating each step. Comfort medications support sleep, anxiety, and autonomic symptoms. Unlike alcohol detox, where 5–7 days is the standard, benzodiazepine detox often extends 14–30 days in the inpatient setting before stepping down to a residential or PHP environment where the taper continues at a slower rate.
Underneath the medical taper, our team addresses what the benzodiazepine was being used for. Most people on long-term benzodiazepine therapy have been managing anxiety, PTSD, or insomnia. Removing the medication without building alternative tools — non-benzodiazepine medication options, evidence-based therapies for anxiety and trauma, sleep architecture work — leaves people in worse shape than when they started. Detox here is not just "come off Xanax"; it's "come off Xanax with a plan for the anxiety underneath."
After Detox
What comes next.
Most people stepping out of inpatient benzodiazepine detox continue the taper in a residential or partial hospitalization setting for another 2–8 weeks. The complete clinical picture often includes treatment for an underlying anxiety, mood, or trauma condition that the benzodiazepine was managing — typically with non-benzodiazepine medications and evidence-based therapies (CBT, ACT, EMDR depending on the picture).
Post-acute withdrawal can last months. The work during this phase is supportive: maintaining structure, building sleep hygiene, continuing therapy, managing flares of anxiety with the new toolkit rather than the old one. The good news is that the trajectory is real — most people, once through the protracted window, end up with better baseline function than they had during long-term benzodiazepine use.
FAQ
Common questions.
Is 5mg diazepam strong?
5mg of diazepam (Valium) is a moderate clinical dose — equivalent to roughly 0.5mg of alprazolam (Xanax) or 0.25mg of clonazepam (Klonopin). It's commonly used as a starting dose for acute anxiety in benzodiazepine-naive patients. In a tapering protocol for someone with established tolerance, doses can range much higher. The strength depends entirely on tolerance, what it's being used for, and what other CNS depressants are involved.
How long does benzodiazepine withdrawal last?
The acute medical window is 1–4 weeks depending on starting dose and how the taper is structured. Post-acute symptoms (anxiety, insomnia, sensory sensitivity) can persist for months, sometimes longer than a year in people coming off high doses or very long-term use. Medical detox is just the start; the protracted recovery is part of why a structured aftercare plan matters so much.
Is benzodiazepine withdrawal dangerous?
Yes — benzodiazepine withdrawal is one of the two drug withdrawals (alongside alcohol) that can be fatal without medical supervision. Abrupt cessation after sustained use can produce grand mal seizures, severe blood pressure instability, and a delirium-like state. Never stop benzodiazepines cold turkey after sustained use. A supervised taper is the only safe approach.
Can I detox from Xanax at home?
Strongly not recommended. Xanax (alprazolam) is short-acting, meaning its pharmacokinetics produce particularly difficult withdrawal — and the seizure risk is real. Even "slow" home tapers from Xanax often fail because of the inter-dose withdrawal symptoms. Medical detox typically converts you to a long-acting equivalent (Valium or Librium) first, then tapers that — far more tolerable and far safer.
What's the safest way to come off benzodiazepines?
A medically supervised taper, typically over weeks to months depending on starting dose. For short-acting benzodiazepines, the standard is to convert to a long-acting equivalent first, then reduce that gradually. Adjunct medications (anticonvulsants, beta-blockers, non-benzodiazepine anxiety treatments) support the taper. Concurrent treatment for the underlying condition (often anxiety, PTSD, or insomnia) is essential — coming off without it leads to high relapse.
Will I get my Xanax back if I can't handle the taper?
Our approach is collaborative, not punitive. If the taper rate isn't tolerable, the rate slows — that's the right clinical response. The goal isn't to push you to a fall; it's to get you safely to a sustainable place. For most people, the right pace produces a workable experience, even if uncomfortable. Communication with your medical team is the way through.
What's PAWS and how long does it last?
Post-acute withdrawal syndrome (PAWS) is the protracted phase after the medical taper completes — characterized by waxing-and-waning anxiety, sleep disturbance, mood lability, and sensory sensitivity. For benzodiazepines, PAWS can last months to over a year, especially after long-term high-dose use. It's distressing, but it's transient, and people do come out the other side. Structured aftercare and ongoing therapy carry people through.
