Key Points
Symptoms of Xanax withdrawal can manifest in sleep, mood, cognitive, or muscle symptoms.
Stopping Xanax can also cause withdrawal symptoms, some of which can be life-threatening, such as seizures.
Symptoms can begin up to two days after the last dose, though this timing and the duration of symptoms vary from person to person.
People who are physically dependent can reduce withdrawal risk through a medically supervised taper.
Get immediate medical attention if you experience seizures, hallucinations, suicidal thoughts, or any other serious symptoms.
Withdrawal from Xanax can feel unpredictable.
Every new sensation and side effect can make you wonder if it’s normal, if it will pass, or if it’s a medical emergency. That is understandable. Benzodiazepine withdrawal is a difficult thing to go through, especially when you aren’t sure what to expect.
If you or someone you love is trying to quit Xanax and is concerned about withdrawals, this guide will walk you through what Xanax withdrawal looks like, how the timeline plays out, and some tips to help you get through it safely.
Why Xanax Withdrawal Happens
Withdrawal happens as your body struggles to readjust to functioning without a substance.
When you take a medication long-term, or in high doses (especially a benzodiazepine like Xanax), your body becomes accustomed to it and begins to rely on it for normal functioning.
Xanax calms anxiety by boosting GABA, a natural brain chemical that slows down the central nervous system.[1]
When you use it regularly, your brain adjusts and produces less of its calming chemicals to compensate. Once Xanax is reduced or stopped abruptly, your brain has to recalibrate. This readjustment is what withdrawal is. For benzodiazepines, this period can be extremely uncomfortable and even dangerous.
Xanax Withdrawal Symptoms
Long-term use of alprazolam can lead to clinically significant dependence, and stopping suddenly or too quickly can cause acute symptoms that are potentially life-threatening, including seizures.[2]
Not everyone experiences the same symptoms during withdrawal, but common symptoms reported include:
Anxiety, irritability, and depression
Trouble sleeping
Blurry vision
Memory problems and difficulty concentrating
Muscle pain, tremors, and heightened sensitivity
Nausea, vomiting, and loss of appetite
Profuse sweating
Stomach cramps
Behavior changes
Hallucinations
In severe cases, seizures
A person can also have rebound anxiety, which is when the symptoms of anxiety return after a person has stopped taking the medication.[3] A licensed therapist or clinician can help identify whether it is withdrawal, an anxiety disorder, depression, another health concern, or a combination.
You should be alert for seizures, muscle twitches, hallucinations, suicidal thoughts, or any other severe change in mental status, as certain symptoms require immediate attention.[4] You should not monitor these at home and wait for them to pass. Get help immediately
Because Xanax boosts GABA, which calms brain activity, when it is reduced or stopped abruptly after the brain has compensated by making less of its own calming activity, nerve cells are left more excitable. This can set off a seizure. Withdrawal can also cause hallucinations and suicidal thoughts.[6]
The risk for these dangerous side effects is higher for people who have been taking Xanax long-term, take high doses, or are misusing the medication.
This is why discontinuing Xanax or any other benzodiazepine medication should only be done under medical supervision. The safest way to discontinue benzodiazepines is through a gradual medical taper based on your symptoms, overall health, medication history, and how you respond as the dose is lowered.[7]

The Xanax Withdrawal Timeline and Acute Withdrawal
Withdrawal can start as early as two days after the last dose of Xanax, a short-acting medication, though this is only a rough estimate and can vary person to person.[8]
Not everyone will experience withdrawal in exactly the same way, but the general timeline is as follows.
Phase
When
What to expect
Early withdrawal
6 to 24 hours after the last dose
Anxiety and trouble sleeping often return first (rebound symptoms)
Peak withdrawal
1 to 4 days after the last dose
Symptoms are at their worst, then gradually ease. Seizures are possible during this period.
Fading physical symptoms
5 to 14 days
Physical symptoms decrease, but mood swings can continue
Lingering symptoms
Weeks to months
Sleep, mood, or concentration problems can continue. Some people have also reported symptoms for more than 12 months.[9]
Coping During Xanax Withdrawal
Withdrawal is difficult, but there are ways to help yourself manage it. Note that these coping strategies should be used together with professional medical care, not as a replacement for it.
Supportive steps include limiting demands on the nervous system, such as:
Reporting new, worsening, or unusual symptoms promptly
Eating at consistent times every day
Having good sleep habits
Learning grounding, relaxation, and mindfulness techniques to calm anxiety
Keeping a log of symptoms, sleep, anxiety, heart rate, blood pressure, and thinking, and sharing it with your treatment team, especially if symptoms suddenly worsen
Some days can be challenging and discouraging. If you feel discouraged, talk to your treatment team and do not change medication after a hard day.

Some people need psychological support to cope with fears, trouble sleeping, uncertainty, substance misuse, or the need for ongoing care. This support can help them reach stability after acute withdrawal.
Research shows that people with an anxiety disorder were more likely to stop taking benzodiazepines when cognitive behavioral therapy (CBT) was combined with a gradual taper.[10] Treatment should consider the person’s diagnosis, risk level, and goals.
Can Xanax Withdrawal Cause Permanent Damage?
It is unclear whether Xanax withdrawal causes permanent damage, and researchers cannot reliably predict how it will affect any one person. Some people report neurological symptoms for months or years after withdrawal, but how common this is remains unclear.[11]
Research on cognitive function is mixed. Many areas improve after withdrawal, but some tests still show impairment compared with controls.[12] That is not conclusive evidence of long-term effects, and it does not mean every continuing symptom is permanent.
If you are experiencing cognitive, sensory, or neurological symptoms, see a licensed medical professional. An assessment should consider benzodiazepine withdrawal along with other possible causes.
Frequently Asked Questions About the Ativan Half-Life
01
What is the half-life of Ativan?
The drug half-life is estimated at about 12 hours, with another clinical estimate of 14 hours and meaningful variation. “Half-life” describes how quickly the drug concentration decreases. It does not measure how long the drug’s effects last or when a drug test will become negative.
02
How long can urine tests detect Ativan?
One method-specific estimate indicates that lorazepam may be detected in a urine test for at least six days. The results will depend on how the test is performed, the cutoff point, how much of the drug you take and when, and your specific characteristics. A lab or doctor should interpret the result
03
Does a 1 mg dose of Ativan leave the body faster?
A 1 mg dose produces a lower drug concentration than a larger dose, but it does not have a separately established half-life. It will be eliminated more quickly than a larger dose, though exact timelines vary person to person.
04
Can I stop taking Ativan when its effects wear off?
Speak to your doctor or health professional before you stop or reduce the dose of this drug if you use it regularly. Withdrawal can be very serious if it happens suddenly because even though you no longer feel the drug’s effects, your body may still be dependent on it.
05
When will a benzodiazepine screen miss lorazepam?
Some routine screens use cutoffs that are not sensitive enough for lower-dose benzodiazepines such as lorazepam. A clinician or laboratory may consider more specific confirmatory testing when an accurate result is medically important.
