Benzodiazepines such as Xanax, Klonopin and Valium are prescribed for anxiety, panic disorders, seizures and insomnia, and the body can grow dependent on them in a matter of days or weeks, even at the prescribed dose. This page explains how dependence differs from addiction, what the warning signs look like, why quitting suddenly can be life-threatening and what treatment involves.
Key Points About Benzodiazepine Addiction
- Physical dependence can start after days to weeks of steady use, even in people following their prescription exactly.
- Warning signs include using more than prescribed, running out early and visiting more than one prescriber.
- Stopping suddenly can trigger seizures and can be life-threatening, so dose changes belong with a prescriber.
- With a short-acting benzodiazepine, withdrawal often starts a day or two after the final dose and can last for weeks.
- No medication is FDA-approved for benzodiazepine addiction; treatment centers on gradual tapering and therapy.

What Is Benzodiazepine Addiction?
Benzodiazepine addiction, called benzodiazepine use disorder in clinical settings, is a pattern of taking a benzodiazepine in harmful ways, being unable to cut back, and often feeling cravings. These drugs are prescription sedatives, and MedlinePlus explains that they calm the brain by reducing its activity, which produces relaxation.
Addiction is not the same as physical dependence. Dependence can develop in anyone who takes these medications steadily for several days to weeks, even as prescribed, and on its own it is not addiction. The difference between addiction vs. dependence matters, but both make stopping suddenly risky. Every benzodiazepine carries a boxed warning, the strongest the Food and Drug Administration (FDA) requires, because of the dangers of addiction, misuse, withdrawal reactions and physical dependence. The FDA reports an estimated 92 million benzodiazepine prescriptions were dispensed from U.S. outpatient pharmacies in 2019.
In 2025, about 1.5 percent of people aged 12 or older, 4.2 million people, misused a prescription tranquilizer or sedative in the past year, a group that includes benzodiazepines, according to the Substance Abuse and Mental Health Services Administration (SAMHSA). SAMHSA also estimates that about 1.7 million people in that age group had a tranquilizer or sedative use disorder that year.
Existing guidelines generally recommend limiting benzodiazepine use to 2 to 4 weeks, with exceptions for certain conditions, according to the American Society of Addiction Medicine. Anyone who has taken one longer and is thinking about stopping should talk to their prescriber first.
Signs and Symptoms of Benzodiazepine Addiction
The earliest signs of benzodiazepine addiction often appear in the way a person uses the medication: taking larger amounts than the prescription calls for, finishing a supply ahead of schedule, visiting several prescribers, or mixing it with alcohol or opioids. Physical signs appear as well: drowsiness, slurred speech, trouble walking steadily and problems with memory. Feeling unwell when cutting back or missing a dose points to physical dependence, and the withdrawal symptoms that can follow are covered further down this page. A prescription by itself is none of these things; many people take benzodiazepines exactly as directed.
Physical signs
The Mayo Clinic lists these physical signs seen with anti-anxiety medicines and sedatives:
- Drowsiness
- Confusion
- Unsteady walking
- Slurred speech
- Poor concentration
- Dizziness
- Problems with memory
- Slowed breathing
Combining a benzodiazepine with other substances raises the risk. The Food and Drug Administration (FDA) urges particular caution when benzodiazepines are prescribed with opioids, and warns that alcohol can increase the risk of serious and life-threatening side effects.
Behavioral signs
The behavior changes the Mayo Clinic describes can be easier to spot than the physical ones:
- Taking higher doses than prescribed
- Requesting early refills or continually “losing” prescriptions, so more prescriptions must be written
- Trying to get prescriptions from more than one prescriber
- Forging, stealing or selling prescriptions
- Being hostile or having mood swings
- Sleeping less or more
Psychological signs
Craving is one of the criteria the Substance Abuse and Mental Health Services Administration (SAMHSA) describes for sedative, hypnotic and anxiolytic use disorders. Other psychological signs include:
- Strong cravings for the medication
- Mood swings
- Anxiety, irritability or insomnia when cutting back or stopping, which are withdrawal symptoms
Only a clinician can say whether these signs add up to a substance use disorder. That diagnosis rests on the full set of DSM-5 criteria, and SAMHSA describes severity by how many are met: two to three symptoms is mild, four to five is moderate, and six or more is severe. Physical dependence is a separate matter. The FDA notes that this can happen even in someone taking a benzodiazepine exactly as prescribed.
Worried About Someone?
Start with an honest, unhurried conversation. Say what you have noticed in plain terms, without blame or labels, and listen more than you talk. When the medication comes from a prescriber, urge them to raise it with that prescriber before they change anything about how they take it. When they are ready for more support, you can find a local treatment center together and share the practical work of making calls.
Signs can also differ from one benzodiazepine to another. The drug-specific pages go deeper on one medication at a time, starting with Xanax addiction. If you are reading because of someone you love, Worried about someone? is written for that situation.
Benzodiazepine Withdrawal: Symptoms, Timeline and Safety
Benzodiazepine withdrawal can be life-threatening, so nobody should stop suddenly or cut a dose quickly without medical guidance. The Food and Drug Administration (FDA) warns that quitting these drugs abruptly, or reducing the dose too quickly, can trigger withdrawal reactions that include seizures, and the National Institute on Drug Abuse (NIDA) says anyone dependent on central nervous system depressants should not attempt to stop alone. According to the World Health Organization (WHO), the first symptoms tend to show up 1 to 2 days after the final dose of a short-acting benzodiazepine, and 2 to 7 days after a long-acting one. Across the drug class, StatPearls puts onset at 2 to 10 days after the last dose, with symptoms that can last for weeks and, for some people, for months. That is why a prescriber tapers the dose slowly, so that stopping carries less risk.
Quitting a benzodiazepine all at once, or reducing the dose too quickly, can bring on seizures and can be life-threatening. Speak with your prescriber first, before you change anything about how you take it.
Withdrawal shows up in the mind and the body at the same time. StatPearls lists the common symptoms in both groups:
Psychological:
- Anxiety, agitation and irritability
- Panic attacks
- Trouble sleeping and poor memory
- Social phobia
- Psychosis, in severe cases
Physical:
- Headache and upset stomach
- Tremor
- Muscle fatigue and weakness
- Seizures
How severe withdrawal gets depends on the dose, how long the drug was taken, its potency, the half-life of the particular benzodiazepine, and how fast the dose is cut, according to StatPearls. Half-life also shapes timing: short-acting drugs such as alprazolam tend to bring withdrawal on sooner than long-acting ones such as diazepam, the WHO notes. Mixing benzodiazepines with alcohol or opioids raises the risk further.
| Phase | Typical timing | What may happen |
|---|---|---|
| Onset | Short-acting drugs (alprazolam, for example): roughly 1 to 2 days after the final dose. Long-acting drugs (diazepam, for example): roughly 2 to 7 days (WHO). Overall range 2 to 10 days (StatPearls) | Anxiety, poor sleep, irritability, headache, tremor and an upset stomach (StatPearls) |
| Acute withdrawal | Short-acting drugs: roughly 2 to 4 weeks, sometimes more. Long-acting drugs: roughly 2 to 8 weeks, sometimes more (WHO) | Panic attacks, agitation, memory problems, and muscles that feel tired and weak. Severe cases can bring a racing heart, high blood pressure, rapid breathing and psychosis (StatPearls) |
| Seizure risk | Greatest when the drug is stopped suddenly or the dose is cut quickly (FDA) | Seizures, which can be life-threatening (FDA). This is an emergency: call 911 |
| Protracted withdrawal | Starts after 4 to 6 weeks; symptoms can persist for weeks and up to 12 months (FDA) | Symptoms that linger and can come and go: anxiety, depression, poor sleep, trouble thinking clearly, a crawling or tingling sensation on the skin, twitching or weak muscles, and ringing in the ears (FDA) |
These ranges are guides, not guarantees. Timing shifts with the drug, the dose and the person. The FDA describes a protracted withdrawal syndrome that persists beyond 4 to 6 weeks after withdrawal begins, with symptoms that may last weeks to as long as 12 months.
Withdrawal is usually handled with a gradual taper: the prescriber reduces the dose slowly at first, adjusting the pace to how the person responds, and sometimes a longer-acting benzodiazepine is used for the process. The American Society of Addiction Medicine (ASAM) cautions clinicians not to stop these drugs abruptly, or cut them quickly, in anyone likely to be physically dependent, and says a taper may run a year or more for long-term users. When withdrawal involves seizures, delirium or other medical problems, StatPearls notes that treatment moves to an inpatient setting.
Some situations call for medical help right away:
- Dial 911 if there is a seizure, severe confusion, hallucinations or breathing that has slowed.
- Reach out to your prescriber before you change your dose, or when a refill is about to run out.
- Call or text 988, the 988 Suicide & Crisis Lifeline, during any mental health or substance use emergency.
- If you drink alcohol or use opioids as well and want to stop, get medical help; going through alcohol withdrawal alongside benzodiazepine withdrawal calls for medical support.
For most people, stopping safely starts with medically supervised detox, where the dose comes down gradually and symptoms are watched as they come. Every drug follows its own clock, which is why withdrawal timelines by substance differ as much as they do.
Go deeper: Xanax withdrawal.
Treatment for Benzodiazepine Addiction
Care typically begins with a slow taper under medical supervision, paired with counseling like cognitive behavioral therapy (CBT). The FDA has approved no medication for benzodiazepine addiction, so care centers on tapering safely, addressing the anxiety or sleep problem that led to the prescription, and support through therapy. Someone who also uses alcohol or opioids needs care for each one, including treatment for alcohol addiction when drinking is part of the picture.
Medications
No medication has FDA approval for treating addiction to CNS depressants, the class benzodiazepines belong to, according to the National Institute on Drug Abuse (NIDA). Prescribers use a gradual dose reduction instead, sometimes switching the person to a longer-acting benzodiazepine first, an approach StatPearls reports has been used in the outpatient setting. NIDA describes this as medically supervised detoxification, because the dose has to come down slowly. It is a safe way off a medication, not a treatment for the addiction itself. The American Society of Addiction Medicine (ASAM) recommends starting slowly and adjusting the pace to how the person responds, and notes a taper can take a year or more for long-term users. Any dose change belongs in the prescriber’s hands.
Behavioral therapies
Because no pill treats the addiction itself, therapy carries much of the work. NIDA reports that people tapering off benzodiazepines often do well with CBT, which gives them practical ways to manage the anxiety, sleep problems and cravings that can surface along the way. Individual, group and family counseling are common parts of treatment, and mutual-help support groups are widely available alongside them.
Where treatment happens
Many people taper through their prescriber’s office or an outpatient rehab program. Inpatient rehab or hospital care is used when withdrawal brings seizures, delirium or other medical problems, according to StatPearls, or when someone is stopping more than one substance at once. These settings, from office visits to a hospital stay, are called levels of care, and the treatment team matches the setting to each person’s medical needs.
Outpatient tapering
Regular follow-up
Inpatient or hospital care
Medical detoxAfter treatment
Recovery does not end when the taper does. Many people keep up counseling or a support group afterward, and care for the anxiety or sleep problem behind the original prescription stays part of the plan.
For many people, the first step is telling their prescriber they want to stop, and there are plain words for how to ask for help when that conversation feels hard. Knowing what to say when you call a rehab makes that first call easier, and the directory makes it easy to find treatment near you.

Types of Benzodiazepines
Benzodiazepines come under many brand names, and pills like Xanax, Ativan, Klonopin, Restoril and Valium are prescribed for anxiety, panic, insomnia and certain seizures. They are often grouped as short-acting or long-acting, based on how long the drug stays active in the body. Five of the most commonly prescribed are below.
Ativan
Ativan is the brand name for lorazepam. According to MedlinePlus, it is used to relieve anxiety and to treat insomnia.
Klonopin
Klonopin is the brand name for clonazepam. MedlinePlus lists its uses as treating certain seizures and panic attacks. DailyMed’s Klonopin prescribing information puts it this way: “clonazepam’s elimination half-life usually runs 30 to 40 hours.” A half-life is the time the body takes to clear half of a dose, so this is one of the benzodiazepines that stays in the system longer.
Restoril
Restoril is the brand name for temazepam. According to MedlinePlus, temazepam is used to treat insomnia.
Valium
Valium is the brand name for diazepam. MedlinePlus lists its uses as relieving anxiety, easing the agitation alcohol withdrawal can bring on, and controlling muscle spasms and seizures.
Xanax
Xanax is the brand name for alprazolam. According to MedlinePlus, it is prescribed for anxiety disorders and panic disorder.
Whichever one is prescribed, every benzodiazepine carries the same risk of physical dependence with steady use, so the withdrawal symptoms and safety guidance on this page apply to all five.
What Are the Risks of Benzodiazepine Addiction?
The most serious risk is overdose, and the danger grows sharply when benzodiazepines are mixed with opioids or alcohol. In 2021, nearly 14% of opioid-involved overdose deaths also involved benzodiazepines, according to the National Institute on Drug Abuse. On August 31, 2016, the Food and Drug Administration (FDA) added Boxed Warnings, its strongest warnings, to both drug classes after warning of serious risks, including death, when opioid pain or cough medicines are taken with benzodiazepines. StatPearls explains why: combining these drugs with opioids can bring on sedation, severe respiratory depression, coma and death. Alcohol is no safer to mix. StatPearls notes that benzodiazepines taken with alcohol increase respiratory depression through a synergistic effect, and the FDA warns that drinking while taking these medications makes serious and life-threatening side effects more likely. Even one occasion of mixing Xanax and alcohol can slow breathing more than either substance would alone.
A benzodiazepine overdose is a medical emergency. Warning signs can include extreme sleepiness, confusion, very slow or shallow breathing and being unable to wake up. If someone shows these signs, call 911 right away, especially if they may have also taken opioids or been drinking.
Long-Term Effects on Memory and Thinking
Not every risk involves an overdose. Used over time, benzodiazepines can affect memory and thinking, even at prescribed doses. The Mayo Clinic names drowsiness, confusion, memory problems and unsteady walking among their effects. These effects matter most for older adults. NCQA reports that the sedation these medications cause brings drowsiness, slower reaction times and poorer balance, and that this raises the chances of falls, hip fractures and other injuries from falls in older adults. That is why, NCQA reports, the 2023 AGS Beers Criteria advise against benzodiazepines for older adults, pointing to the risk of falls, fractures, delirium, cognitive impairment and motor vehicle crashes. Long-term use in this age group is also linked to a higher risk of dementia, NCQA notes, an observed association rather than a proven cause.
Frequently Asked Questions About Benzodiazepine Addiction
Physical dependence can, and it is not the same as addiction. The Food and Drug Administration (FDA) warns that dependence can set in within days to weeks of steady use, even for someone following the prescription exactly. Addiction goes further: it involves harmful use and a loss of control, the pattern behind benzodiazepine addiction itself. Anyone concerned about their use should talk to the prescriber, and the National Institute on Drug Abuse (NIDA) cautions against stopping on one’s own.
Yes. Quitting a benzodiazepine all at once, or lowering the dose too quickly, can bring on withdrawal reactions including seizures, and the FDA warns these can be life-threatening. Prescribers avoid that risk by lowering the dose gradually, an approach both NIDA and the American Society of Addiction Medicine (ASAM) describe. The withdrawal timeline and safety guidance on this page shows what a managed stop involves.
It depends on the drug. Acute withdrawal often lasts about 2 to 4 weeks for a short-acting benzodiazepine and 2 to 8 weeks for a long-acting one, according to the World Health Organization. Some symptoms can persist far longer: the FDA describes cases lasting up to 12 months. These are ranges, not guarantees, and timing shifts with the drug, the dose and the person.
There is no single schedule, the FDA says. The 2025 joint guideline from ASAM recommends starting slowly and adjusting the pace to how the person responds, rather than following a fixed calendar. For long-term users, ASAM says a taper can take a year or more.
No. NIDA states that no FDA-approved medication treats addiction to central nervous system depressants such as benzodiazepines. Treatment instead combines gradual tapering with therapy, and cognitive behavioral therapy (CBT) is one approach used to help people adapt to stopping.
No. The FDA cautions that combining benzodiazepines with alcohol can lead to serious and life-threatening side effects. With opioids the danger is worse: StatPearls and a 2016 FDA warning describe severe breathing problems, coma and death when the two are taken together. Specific combinations such as mixing Xanax and alcohol carry the same class-wide risks.
