How Is Xanax Tapered Safely, Step by Step?

Key Takeaways

• Xanax (alprazolam) is tapered slowly, in small steps, over months, with a prescriber who understands the drug.
• Feeling ill when a dose is late or reduced after months or years of prescribed use is physical dependence, and the Xanax Medication Guide itself says dependence is not the same as addiction.
• Xanax is potent and short acting, so the blood level rises and falls with every tablet, and many people feel withdrawal creeping back between doses.
• Never stop Xanax suddenly, because the 2020 boxed warning on every benzodiazepine label says abrupt stopping can cause withdrawal reactions, including seizures, and a seizure is a reason to call 911.
• The taper begins from a steady daily dose, and many patients then cross over to diazepam (Valium) one dose at a time, because its level falls smoothly and it comes in small tablets and as a liquid.
• Reductions get smaller as the dose gets lower, the way a pilot slows the descent near the ground, and the pace belongs to the patient.
• A flare of anxiety, insomnia or tremor after a cut means the step was too big, so the taper holds, and a small step back up agreed with the prescriber is a legitimate move, not a failure.
• Near the end, a liquid form of the medication makes the smallest steps possible, and the stopping point is agreed in advance with the prescriber.

How is Xanax tapered safely, step by step?

Slowly, in small steps, over months, and with a prescriber who understands the drug. Xanax, or alprazolam, is a benzodiazepine prescribed for anxiety and panic disorder. It is also one of the harder benzodiazepines to come off of, because it is potent and short-acting.

Most people who ask this question took Xanax exactly as prescribed, often for years, and now find that a late or reduced dose makes them feel ill. That is physical dependence, and dependence is not addiction. In fact, the Medication Guide that comes with Xanax says so in plain words: physical dependence is not the same as drug addiction.

What is dependence, then? Benzodiazepines enhance gamma-aminobutyric acid (GABA), the brain’s natural calming chemical. In Chapter I of the Ashton Manual, Professor C. Heather Ashton explains that with regular use the receptors for GABA and benzodiazepines become less responsive.

The brain is not short of GABA. Its receptors have adjusted to the drug, and they need time to adjust back. So, what are the steps, and why does Xanax need them more than most?

Xanax is potent and short-acting, and both facts shape the taper.

Table 1 of the Ashton Manual lists a half-life of 6 to 12 hours for alprazolam, and the drug’s own United States Food and Drug Administration (FDA) label puts the average at about 11 hours in healthy adults. Half-life is the time the blood level takes to fall by half. With a half-life that short, the level rises and falls with every tablet.

Many people feel those dips. The Xanax label reports early morning anxiety, and anxiety emerging between doses, in patients with panic disorder taking prescribed maintenance doses. Patients call this interdose withdrawal, and a person who takes a tablet at 8 am may feel symptoms creeping back by mid-afternoon, before the next one is due.

The second fact is potency. Chapter II of the Manual points out that the smallest Xanax tablet, 0.25 mg, is equivalent to about 5 mg of diazepam (Valium). While a quarter of a milligram sounds small, it is a large step for a nervous system that has adapted to the drug.

First, do not stop suddenly.

In 2020, the FDA required the boxed warning on every benzodiazepine label to be updated. The agency said that physical dependence can occur when these drugs are taken steadily for several days to weeks, even as prescribed, and that stopping abruptly or reducing the dose too quickly can cause withdrawal reactions, including seizures, which can be life-threatening. For a seizure or any other medical emergency, call 911.

The Xanax label carries that warning and tells prescribers to use a gradual taper. Chapter II of the Ashton Manual adds that abrupt or over-rapid withdrawal may increase the risk of protracted withdrawal symptoms.

Unfortunately, fast tapers still happen, in facilities where a discharge date sets the timeline and in offices where a prescription is not renewed. The FDA’s advice to patients is not to stop suddenly without first discussing a plan for slowly decreasing the dose.

Second, steady the dose before changing it.

A taper starts from a stable baseline. That means the same total dose each day, taken at regular times. Extra tablets on bad days and skipped tablets on good days make what follows harder to read.

While this step can feel like standing still, it does real work. Once the days are even, a rough afternoon can be traced to the last reduction, and not to the ordinary dip before the next dose.

Third, decide with the prescriber whether to cross over to diazepam.

For potent, short-acting drugs such as alprazolam, Chapter II of the Ashton Manual advises a switch to a long-acting, slowly eliminated benzodiazepine such as diazepam. Its level falls smoothly between doses, and it comes in small tablets and as a liquid, so the reductions can be small. The switch, followed by the gradual reduction, is known as a crossover taper.

Dr. Mark Leeds, an osteopathic physician and deprescribing specialist in Fort Lauderdale, Florida, generally prefers the crossover. In his clinical experience, patients who are able to taper with diazepam tend to have a more comfortable taper. A separate article explains switching from Xanax to Valium.

Yet, the crossover does not suit everyone. Some people find diazepam too sedating, and some process it unusually slowly or quickly. For alprazolam, Dr. Leeds’ preferred alternative is then a crossover to clonazepam (Klonopin), and some patients taper alprazolam itself, using a liquid. The choice is made with the patient.

Fourth, the switch is made one dose at a time.

The crossover is not a one-day swap made before the taper begins. It is the first phase of the taper. The Manual says to substitute one dose at a time, usually starting with the evening or night-time dose, and then to replace the other doses one by one.

In Schedule 1, the Manual’s example for a person taking a high daily dose of alprazolam, nothing is reduced in the opening stages. Part of the day’s alprazolam is exchanged for diazepam, the new arrangement is held for about a week, and then the next part is exchanged.

Why so gradual? Because the equivalence figures are approximate, and Table 1 notes that they may vary from person to person. Going one dose at a time lets patient and prescriber find the dose of diazepam that prevents withdrawal symptoms without causing sleepiness.

Fifth, the dose comes down in small steps over months.

Once the dose is stable, the reductions begin. The Manual suggests steps of up to one tenth of the dose, and it says the person taking the medication must be in control of the pace. The Maudsley Deprescribing Guidelines describe the shape as hyperbolic, meaning that each step gets smaller as the dose gets lower.

Think of landing an airplane. Nobody lands by flying straight down. The pilot descends gradually, levels off when needed, and slows the descent near the ground, so that the touchdown is barely felt.

While this is not a perfect analogy, a taper follows the same rule. Come down slowly, and slowest at the end.

How long does it take? The Manual’s example schedules are set out by drug and by dose, and it describes the pace as an individual matter. Professor Ashton wrote that the rate, as long as it is slow enough, is not critical, and that whether it takes 6 months, 12 months, or 18 months is of little significance for someone who has taken benzodiazepines for years. The steps for any one person are worked out with that person’s own prescriber, not copied from a page.

What happens when a step is too big?

Anxiety, insomnia, tremor, sweating, nausea, and muscle pain can flare after a reduction. A flare of this kind says that the step was too large or came too soon. It is not a failure.

So, the taper holds at the current dose for a short stretch while things settle, and then continues with smaller steps. A hold that does not settle within a few weeks is a reason to talk with the prescriber about the next step, which on alprazolam may be a slower rate, a crossover to diazepam, or continuing the taper, planned together and never by stopping suddenly, rather than an open-ended wait. The Xanax label tells prescribers much the same: if withdrawal reactions develop, consider pausing the taper or going back to the previous dose, and then decrease more slowly. A small increase after a cut that proved too large is a legitimate part of a taper.

Sixth, a liquid makes the smallest steps possible.

Near the bottom of a taper, the steps a person needs are smaller than any piece a pill cutter can make. The Ashton Manual notes that liquid preparations allow slow reduction by decreasing the volume of each dose with a graduated syringe.

A compounding pharmacy can prepare alprazolam or diazepam as a liquid at a strength the prescriber chooses, and diazepam is also manufactured as an oral solution. The liquid is the same medication in a form that can be measured finely. Nothing else is mixed in to treat withdrawal.

Where does the taper stop? Dr. Leeds’ plain rule is that the last step should feel like just another step, and the stopping point is agreed in advance. A separate article covers how low a taper should go before the last dose.

What about the months after the last dose?

Symptoms usually ease with time. Yet, for some people they come and go for a while, in the windows and waves that patients describe. The Xanax label acknowledges a protracted withdrawal syndrome that, in some cases, lasts from weeks to more than 12 months.

A gradual taper is thought to lower that risk, which is one more reason not to rush. Fortunately, withdrawal does get better with time, and protracted withdrawal is covered in its own article.

The pace belongs to the patient.

If the pace is too fast, the doctor must slow it. If the patient is doing well and wants to move on, patient and doctor may agree to take the next step.

Frequently asked questions

Can Xanax be stopped suddenly after it was taken as prescribed?

No. The 2020 boxed warning on every benzodiazepine label says that stopping abruptly or reducing the dose too quickly can cause withdrawal reactions, including seizures, which can be life-threatening, and the Xanax label tells prescribers to use a gradual taper. In fact, the Ashton Manual adds that over-rapid withdrawal may raise the risk of protracted symptoms. For a seizure or any other medical emergency, call 911.

Why is Xanax often switched to Valium before the taper?

Because alprazolam is potent and short acting, its level falls between doses, and even the smallest tablet is a large step for a nervous system that has adapted to the drug. Chapter II of the Ashton Manual advises switching to a long-acting benzodiazepine such as diazepam, whose level falls smoothly and which comes in small tablets and as a liquid. Dr. Leeds generally prefers this crossover. Yet, when diazepam does not suit a patient, a crossover to clonazepam or a direct taper of alprazolam with a liquid are the alternatives.

What is interdose withdrawal?

It is withdrawal that arrives between doses. The Xanax label reports early morning anxiety, and anxiety emerging between doses, in patients taking prescribed maintenance doses. So, a person who takes a tablet at 8 am may feel symptoms returning by mid-afternoon, before the next one is due. A steady daily dose, and for many patients the crossover to a longer-acting benzodiazepine, is what smooths those dips.

What should happen when a reduction causes withdrawal symptoms?

The taper holds at the current dose for a short stretch while things settle, and then continues with smaller steps. A hold that does not settle within a few weeks is a reason to talk with the prescriber about the next step, which on alprazolam may be a slower rate, a crossover to diazepam, or continuing the taper, planned together and never by stopping suddenly, rather than an open-ended wait. The Xanax label tells prescribers much the same: if withdrawal reactions develop, consider pausing the taper or going back to the previous dose, and then decrease more slowly. A flare after a cut says the step was too large or came too soon. Fortunately, a small increase agreed with the prescriber is an ordinary part of a taper, and it does not mean the taper has failed.

How long does a Xanax taper take?

There is no fixed timeline. Professor Ashton wrote that whether a taper takes 6 months, 12 months, or 18 months is of little significance for someone who has taken benzodiazepines for years, and the steps for any one person are worked out with that person’s own prescriber, not copied from a page.
