Can You Stop a Benzodiazepine Cold Turkey After Only a Few Days or Weeks?

Key Takeaways

• A few days of carefully prescribed use, such as after surgery, can usually be stopped without a problem.
• Withdrawal can follow even several days of steady use, although it is usually mild and short-lived.
• After about four weeks of regular use, stopping abruptly is not advised.
• As-needed use of a short-acting drug like Xanax (alprazolam) can creep up over time until dependence arrives unnoticed.
• Longer use, higher doses, and short-acting drugs all raise the risk of withdrawal.
• Most symptoms after brief use are mild and pass, but new or severe symptoms deserve medical attention.
• Decisions about stopping a benzodiazepine belong with your prescriber.

Is it safe to stop a benzo cold turkey if you only took it for a short time?

You took a benzodiazepine for a few days, or a few weeks, and then you stopped. Now you feel shaky or cannot sleep, and a late-night search has convinced you that your nervous system is damaged for good. Or, you are still taking it and wondering whether a taper is really necessary for something so brief.

The honest answer depends on three things: how long you took it, how often you took it, and which drug it was. For a few days of carefully prescribed use, stopping is usually not a problem. For daily use over several weeks, it can be. And, for as-needed use that has slowly become more frequent, the answer may have changed without anyone noticing.

So, where does short-term use end and physical dependence begin?

A few days after surgery is usually not a problem.

Surgeons sometimes prescribe a benzodiazepine such as Ativan (lorazepam) or Valium (diazepam) for a few days around a procedure, to help with sleep, muscle spasm, or nerves. In Dr. Leeds’ experience, when that prescription is careful and short, up to about a week, stopping abruptly is usually not a problem.

That does not mean the body notices nothing. The Maudsley Deprescribing Guidelines note that the 2020 United States Food and Drug Administration (FDA) boxed warning “points out that withdrawal effects from benzodiazepines can even occur when the medication is taken ‘steadily for several days’, although presumably symptoms are more likely to be mild and short-lived in these circumstances” (chapter 3, p. 310).

In practice, that may look like a few nights of poorer sleep or some edginess that fades on its own. This is rebound. It passes.

Several weeks of daily use changes the answer.

Benzodiazepines work by strengthening gamma-aminobutyric acid (GABA), the brain’s main calming messenger. When a benzo is taken every day, the brain adjusts to its presence by turning its own calming system down. Remove the drug suddenly, and the brakes are weaker than they were before you started.

That adjustment is physical dependence, and it can arrive faster than many people are told. In the first chapter of the Ashton Manual, Professor C. Heather Ashton wrote that benzodiazepines “are recommended for short-term use only (2-4 weeks maximum),” and that “psychological and physical dependence can develop within a few weeks or months of regular or repeated use.” The Maudsley Deprescribing Guidelines are just as plain: “Patients should be warned not to stop benzodiazepines abruptly if they have been used for more than 4 weeks” (chapter 3, p. 349).

Fortunately, a few weeks of use does not usually call for a long taper. The Maudsley Deprescribing Guidelines give the example that alprazolam taken for three weeks would need a taper of less than three weeks (chapter 3, p. 368). The shape is a short, gradual step down, slowed for anyone who reacts to the reductions, and planned with your prescriber rather than guessed at.

None of this says anything about character. Dependence is not addiction. A brain that adapts to a medication taken exactly as prescribed is doing what brains do, and physical dependence is what makes quitting difficult, not a lack of willpower.

Does it matter which benzodiazepine you took?

Yes, it does. The Maudsley Deprescribing Guidelines note that “A longer duration of use correlates with a greater intensity of withdrawal symptoms, as do higher doses. Shorter-acting benzodiazepines also are associated with higher risks of withdrawal” (chapter 3, p. 318).

Xanax is potent and short-acting, meaning it rises quickly and leaves quickly. Valium stays in the body much longer, so its level falls more gradually on its own. While no benzodiazepine is free of risk to stop, the short-acting ones give the brain less time to adjust as the drug disappears.

On alprazolam specifically, the Maudsley Deprescribing Guidelines say physical dependence and withdrawal can occur when it is taken “for several days to weeks, even as prescribed.” They add that “Not everyone who stops alprazolam will experience withdrawal and some of those who do will only experience mild symptoms,” yet “in a very few instances, stopping abruptly can cause seizures and can be life threatening” (chapter 3, p. 364).

As-needed Xanax can quietly turn into daily Xanax.

This is the risk Dr. Leeds sees most often, and it is the one nobody warns about. Occasional use of a potent, short-acting benzodiazepine such as Xanax may not cause dependence at first. Yet, for many people, the frequency creeps up over months, often without their being aware of it.

While this is not a perfect analogy, think of sitting on a beach as the tide comes in. No single wave seems to move the water line. An hour later, your towel is wet. Once a week becomes twice a week, then most evenings, and each step feels too small to count.

The result is a person who had no dependence for a long time and then, later, does. Stopping cold turkey was possible at the beginning. In Dr. Leeds’ view, it is no longer a safe option once that point has quietly passed.

So, look at the water line, not the wave. Signs worth bringing to your prescriber include taking it more often than you did six months ago, taking it ahead of situations rather than during them, and anxiety about running out. Feeling edgy as each dose wears off, a pattern known as interdose withdrawal, is another, as is finding that the same dose does less than it once did, which is tolerance withdrawal. None of these is a diagnosis. Each is a reason to have a conversation before making any change.

What if you already stopped abruptly and now feel unwell?

Did stopping suddenly cause lasting harm? After short-term use, that is uncommon, even though it can feel certain at two in the morning. Most symptoms after brief use are mild, and they fade as the brain readjusts.

Still, abrupt stopping is the riskiest way to come off a benzodiazepine. The Maudsley Deprescribing Guidelines note that “Abrupt cessation also probably presents the greatest risk of developing protracted withdrawal symptoms” (chapter 3, p. 330). After regular use, a benzodiazepine should never be stopped abruptly. The 2020 FDA label update calls for a gradual taper instead, because sudden stopping can bring on withdrawal reactions.

If you already stopped and feel unwell, do not restart on your own, and do not tough it out in silence. Talk with your prescriber, who can weigh whether a short, gradual plan would help. Call 911 for a seizure, and seek emergency care for confusion, hallucinations, or any symptom that feels severe. If the distress brings thoughts of harming yourself, call or text the 988 Suicide & Crisis Lifeline.

Questions people often ask about short-term use.

Is a taper needed after two weeks of Klonopin?

Possibly a short one. Klonopin (clonazepam) is longer-acting than Xanax, which softens the drop, but two weeks of daily use can be enough for the brain to adjust. Your prescriber can judge whether a brief step down makes sense for your dose and history.

Can a few days of Ativan after surgery cause withdrawal?

It can cause mild rebound, such as a few restless nights. For a carefully prescribed course of about a week or less, stopping is usually not a problem, and those symptoms pass.

Is it dangerous to stop Xanax cold turkey after only occasional use?

That depends on what “sometimes” has become. Truly occasional use carries little risk. If sometimes has drifted into several times a week for months, talk with your prescriber before stopping.

Can short-term use cause protracted withdrawal?

It is uncommon, but not impossible, and abrupt stopping carries the greatest risk. Repeated sudden stops can also make later withdrawal harder, a process called kindling, which is one more reason deprescribing designed to avoid protracted withdrawal starts with a plan rather than a sudden stop.

The brain adjusts on its own schedule.

A short prescription taken for a short time usually ends quietly. When use has stretched longer, or crept up without notice, the brain simply needs more time to readjust, and there is no shame in giving it that time.
