How Long Does Protracted Benzodiazepine Withdrawal Last, and Does a Slow Taper Lower the Risk?

Protracted withdrawal is what happens when the symptoms outlast the drug.

Most people who stop a benzodiazepine feel the worst of it in the first few weeks and then improve. For some, the symptoms do not fade on schedule. They persist for months, sometimes years, after the drug has left the body, and that is protracted withdrawal.

The United States Food and Drug Administration (FDA) defined protracted withdrawal syndrome in its September 2020 boxed-warning update: symptoms that persist beyond four to six weeks and may last as long as twelve months. Professor C. Heather Ashton, in Chapter III of the Ashton Manual, describes a longer tail, occasionally several years.

Many now call this injury benzodiazepine-induced neurological dysfunction (BIND), a name that also covers symptoms that begin while the drug is still being taken. The name says what it is: a disturbance of the nervous system caused by the drug and by how it was stopped, not weakness and not the return of the original anxiety. Dr. Mark Leeds, an osteopathic physician and deprescribing specialist in Fort Lauderdale, Florida, sees the same problem under both names.

Needing a long time to heal does not mean addiction.

Nearly everyone with protracted symptoms took the drug as prescribed. The FDA’s 2020 update states that physical dependence can develop when a benzodiazepine is taken steadily for several days to weeks, even as prescribed, and it defines dependence separately from abuse and addiction. Dependence is not addiction. Addiction is a pattern of behavior; dependence is a change in the nervous system, and it is treated by tapering.

That distinction decides everything that follows. A person with physical dependence needs a slow, medically supervised taper and then time to heal, not a facility stay measured in days, a label they never earned, or a doctor who doubts that the condition exists.

What does protracted withdrawal feel like?

The symptoms come in waves, and between the waves there are windows. Professor Ashton observed that symptoms wax and wane from day to day and even within a day, and that windows of normality appear after some weeks and gradually grow more frequent and longer.

The sensory symptoms are the strangest to an outsider. Chapter III of the Manual lists tinnitus, tingling, numbness, burning pain, and an inner trembling others cannot see, alongside muscle pain, weakness, cramps, tremor, and jerks. Memory and concentration suffer, sleep is fragile, digestion is disturbed, and anxiety and depression can run deeper than anything felt before the drug.

The suffering is hard to imagine for anyone who has not lived it, and tests usually come back normal, which invites the suggestion that it is all in the patient’s head. It is not. Depression in a long wave can be dangerous, and anyone with thoughts of ending their life can call or text the 988 Suicide & Crisis Lifeline.

How long does it last? The Ashton Manual gives a shape, not a date.

Nobody can give a date, and a doctor who does is guessing. What the Manual offers is a shape: anxiety gradually diminishing over about a year, insomnia over six to twelve months, and the sensory, motor and cognitive symptoms lasting at least a year and occasionally several years. Professor Ashton adds that protracted symptoms keep declining in severity over the years.

So, most people improve within a year, some carry a few symptoms longer, and the trend points toward healing the whole time. The Manual estimates that only a minority of long-term patients develop protracted symptoms at all, and adds that the incidence in those who tapered slowly, under their own control, is almost certainly very much lower.

Unfortunately, the fastest way to stop is the surest way to make it last.

Chapter II of the Manual is blunt: abrupt or over-rapid withdrawal, especially from a high dose, can produce severe symptoms and may increase the risk of protracted withdrawal. The FDA’s 2020 update agrees: stopping abruptly or reducing the dose too quickly can cause withdrawal reactions, including seizures, which can be life-threatening. A seizure or any other medical emergency is a reason to call 911 at once.

People searching for benzo detox usually find facilities offering a stay measured in days. That is the over-rapid withdrawal the Manual warns against, and safe discontinuation means a gradual, medically supervised taper over months, sometimes longer. The nervous system sets the calendar, not an insurance plan.

The Manual allows one exception: for triazolam (Halcion) the Manual lists a half-life of about two hours, so a person is practically withdrawn from it every day, and Professor Ashton says it can be stopped abruptly without substituting a long-acting benzodiazepine. Dr. Leeds prefers a gradual taper even there, consistent with the drug’s own label, and the exception covers no other drug.

Fortunately, a slow taper has a known shape.

The schedules in Chapter II of the Manual take off up to one tenth of the dose at each step and hand the pace to the patient, who Professor Ashton says is usually the best judge of it. The Maudsley Deprescribing Guidelines add the hyperbolic shape: each reduction is a fraction of the current dose, so the steps shrink as the dose falls, and the last ones are small enough to need a liquid formulation.

A good taper is a staircase with shrinking steps and a landing wherever one is needed. When a reduction brings a wave, the dose is held on that landing until the wave passes. The Manual’s advice is to avoid going backwards as far as possible: hold rather than increase. A hold is not a failure.

For the short-acting drugs the Manual adds a first move, the crossover taper to diazepam (Valium). Alprazolam (Xanax) and lorazepam (Ativan) leave the body so quickly that many people feel withdrawal between doses, so Chapter II substitutes diazepam one dose at a time, usually starting with the night-time dose, and tapers from there. Dr. Leeds uses the crossover where it helps, and the Xanax tapering guide walks through the shape.

Z-drugs such as zolpidem (Ambien) and zaleplon (Sonata) act on the same gamma-aminobutyric acid (GABA) receptor that benzodiazepines do and are tapered on the same principles, as the zaleplon guide explains. None of this is a schedule to copy from a page.

What helps once the taper is over and the symptoms remain?

Time, mainly, and it is better to say so than to sell something. The Manual’s advice for protracted symptoms is plain: stop worrying about them, because fear makes every symptom worse, exercise the body, exercise the brain, and widen the interests that fill a day. Sleep, gentle activity, regular meals, and enough fluids do more than they sound like they would.

Two things to avoid stand out. Chapter II warns against compensating for the lost benzodiazepine with alcohol, which acts on the same GABA receptor, and going back on a benzodiazepine regularly risks re-establishing the dependence, though the Manual notes that a single dose given for an operation does not bring it back.

What about supplements, massage, acupuncture, and yoga? The evidence is limited, and the Manual observes that the effects of complementary therapies tend to be short-lived and dependent on the person. They can be pleasant if they are safe and the prescriber knows, but nothing on that list shortens the course.

Family members help most by believing it.

The people closest to a person with protracted withdrawal often get it wrong in the same way the medical system did. They mistake dependence for addiction, urge the person to just stop, or wonder aloud why someone with normal tests cannot get off the couch. Each adds a burden to a nervous system already carrying too much.

What helps is simpler and harder. Believe the symptoms, learn what windows and waves are, and do the practical things on bad days, the meals, the driving, the phone calls, without keeping score. Measure progress by the month, not the week, and protect the person from anyone who pushes them to speed up. Peer communities can ease the isolation, and support-group programs are not medical care, so neither replaces a physician who understands deprescribing.

A doctor who understands deprescribing starts by believing the patient.

Many patients trust doctors less than they once did, and with reason. The drug came with an assurance that it was safe, and the same office may now say that withdrawal cannot last this long. A doctor who understands deprescribing starts from the opposite assumption: the patient is describing a real condition, and the Ashton Manual and the Maudsley Deprescribing Guidelines describe how to treat it.

Yet, knowing the guidelines is only the beginning. The doctor must be willing to hold the dose when the patient asks, to go slower than any chart suggests, and to treat the plan as the patient’s own. Informed consent means the risks are explained first, the alternatives are laid out, an exit plan exists from the first visit, and the patient may decline any step without losing the doctor.

Dr. Leeds is an osteopathic physician and deprescribing specialist, and this is the work his practice does. He also helps patients taper other psychiatric medications, since a taper plan has to account for everything a person takes.

Dr. Leeds’ practice in Fort Lauderdale, Florida, offers one service: medically supervised benzodiazepine and z-drug tapering for patients in Florida, as a concierge practice rather than through insurance. The taper follows the Ashton Manual and the Maudsley Deprescribing Guidelines at a pace the patient sets over months or longer. Contact Dr. Leeds to ask about a supervised taper.
