Benzodiazepines are helpful for treating many mental health conditions. However, quitting a benzo abruptly can lead to potentially life-threatening withdrawal symptoms.

Benzodiazepines, commonly known as benzos, are a class of prescription medications often used to treat anxiety or insomnia. Benzodiazepines are classified as Schedule IV medications under the Controlled Substances Act, meaning they carry a risk for abuse even when taken as prescribed.

Benzos can also lead to the development of dependence and addiction. When someone is dependent on benzos, they will experience uncomfortable withdrawal symptoms when they stop using the drug. Severe withdrawal symptoms such as seizures can be dangerous, so it’s important to seek help when trying to stop benzodiazepine use.

What Is Benzo Withdrawal?

Benzos slow down signals between the body and the brain by activating gamma-aminobutyric acid (GABA). Because of this, benzos have a calming or sedative effect and can effectively treat anxiety or seizures. However, when benzos are taken for a prolonged period, your body can become dependent on the drug. Dependence occurs when your body adjusts to the presence of the drug, and this can impact the drug’s effects. When you suddenly stop taking the medication, your body does not have time to adjust to the drug’s sudden absence, which can cause withdrawal.

Benzo Withdrawal Symptoms

Benzo withdrawal occurs after stopping the drug too quickly, and it creates many symptoms related to the hyper-excitability of the brain. These symptoms include:

  • Sleep changes
  • Irritability
  • Anxiety
  • Panic attacks
  • Tremors
  • Sweating
  • Difficulty concentrating
  • Nausea
  • Weight loss
  • Palpitations
  • Headache
  • Muscle pain and stiffness
  • Seizure

Benzo Withdrawal Seizure

One of the biggest risks of abruptly stopping benzos is seizures. This risk is highest about five to seven days after stopping benzo use, but seizures can happen as soon as the day after quitting the drug. Unfortunately, even if benzos are taken as prescribed, the risk of seizures is present when quitting.

Epilepsy during withdrawal can happen even if you use benzos at a low dose and for as little as one week, but the risk is higher with larger doses or long-term use. Benzo withdrawal seizures are possible for up to six months after stopping benzo use. Higher doses or longer-term use make the risk of developing epilepsy more likely.

Benzo Belly From Benzo Withdrawal

“Benzo belly” is a term that describes certain symptoms that can occur after stopping a benzo. These can include bloating, stomach pain, constipation and other painful GI symptoms. These effects may occur because of the relationship between the gut and the brain. Researchers believe that bacteria in the gut may produce some of the same chemicals used in the brain. While more information is necessary regarding benzo withdrawal, it could be possible that the changes in the brain are what cause these changes to the GI system.

Benzo Withdrawal Timeline

The benzo withdrawal timeline may vary depending on which benzo a person takes and how much. In general, benzo withdrawal occurs in a few different phases.

  • Phase one: One to four days after stopping benzos, rebound anxiety and insomnia can occur.
  • Phase two: Symptoms intensify as benzodiazepine withdrawal syndrome develops. This phase may last for 10 to 14 days.Phase three: Anxiety may return and can remain for many months if left untreated.

After a few months, most people who stop taking benzos will no longer experience withdrawal symptoms. However, some people experience protracted withdrawal syndrome, which may result in symptoms that continue for years. This syndrome may occur due to structural changes to the brain after prolonged benzo use.

Factors Affecting Benzo Withdrawal Duration

Although the general timeline of benzo withdrawal duration is a good guide, it is not possible to accurately predict how long benzo withdrawal symptoms last. Withdrawal from benzodiazepines varies from person to person. However, benzodiazepine withdrawal symptoms, duration and severity may be influenced by many factors, including:

  • Age and gender
  • General health
  • The health of the liver and kidneys
  • Genetic and biological make-up of the individual
  • Concurrent use of other drugs
  • Co-occurring mental health disorders
  • Whether the withdrawal is medically assisted or not

Can You Die from Benzo Withdrawal?

The most considerable health risk of stopping benzos is the possibility of seizures. Although it is uncommon, this type of seizure can lead to death in some cases. In addition, complications like aspiration are possible, particularly if you have an unwitnessed seizure and cannot call for help. In one case report, a woman stopped taking Xanax after running out of medication and died. She took a very large drug dose (200 mg over six days, despite the maximum recommended dose being less than 24mg).

Benzo Detox

If you want to stop taking benzos, talk with your health care provider. There are safe and effective ways to discontinue this medication while reducing your chance of uncomfortable withdrawal symptoms or health risks.

How To Taper off Benzos

Similar to how your brain needs time to adjust to the presence of benzos, it will take your brain time to adjust to the absence of them. To minimize the risk of withdrawal or seizures, the safest way to stop benzos is to taper off them. Tapering is a process in which you slowly decrease how much you take until you can safely stop. For most, this process will last at least 10 weeks.

How Long Does Detox Take?

The timeline for acute benzodiazepine withdrawal symptoms suggests that most people will have fully detoxed from benzodiazepines within 14 days. Two weeks is typically how long it takes most benzos to be eliminated from your body altogether. However, because benzodiazepine withdrawal syndrome can include protracted symptoms, it is not possible to reliably predict how long it will take to detox from benzos.

How To Find a Detox Center

Detox refers to the period when your body is eliminating substances such as benzodiazepines from its system. During this time, withdrawal symptoms can be particularly intense, leading some to return to benzo use. There are three settings where detox can happen: medical detox, where you are admitted to a medical facility; outpatient detox, where you have regular and frequent visits with a health care provider; or at home.

Medical detox can help you to get through withdrawal safely and comfortably. By providing you with 24-hour medical supervision, health care professionals can treat withdrawal symptoms while also prioritizing your mental well-being. Medical detox facilities also offer the opportunity to meet with others in similar situations and create meaningful connections.

Outpatient detox is similar to medical detox, but it does not provide around-the-clock medical care. In outpatient detox, you and your health care provider determine a safe plan for a benzo taper. Although outpatient detox provides more flexibility, a drawback is that it lacks 24-hour medical attention.

Detoxing at home is possible, but it can be dangerous because medical personnel cannot monitor you for risks such as seizures. However, detoxing at home may be an option if you have taken benzos for a short period or at low doses. A solid support system at home is essential, and you should always speak with your health care provider before attempting an at-home detox.

Benzo Detox Medications

Various medications can help with the uncomfortable symptoms of withdrawal. Detox facilities will monitor you for withdrawal symptoms and prescribe medications as needed.


Buspirone is an anti-anxiety medication that can also help to treat depression. This can be particularly helpful in patients going through benzo withdrawal who experience both anxiety and depression. This medication has few side effects and is usually well tolerated.


Flumazenil is a prescription medication that reverses benzos. It is often used in emergencies as a rescue medication to counteract benzos, similar to how naloxone reverses opioids rapidly. When used at low doses or as a subcutaneous infusion given over four days, flumazenil can help rapidly counteract benzos. However, it is essential to note that this rapid change can sometimes cause seizures, and the drug should only be used in a medical setting with extensive monitoring.


Clonidine is traditionally prescribed as a blood pressure medication. However, this medication has helped many going through withdrawal. It is believed that clonidine helps alleviate anxiety during withdrawal because of its effects on brain neurotransmitters. However, its use is limited by its effects on blood pressure.


Magnesium may be effective in helping to treat drug addiction and abuse. In one study, magnesium was found to reduce the intensity of addiction to various substances. It may also alter brain neurotransmitters in a way that reduces the intensity of withdrawal symptoms. Additionally, magnesium may become deficient in times of stress and lead to a higher likelihood of relapse, so taking magnesium supplements may help.


Keppra is the brand name of levetiracetam and is another antiepileptic medication. Keppra has demonstrated some promise as an option for benzo withdrawal in animal and small-scale human studies. However, as with many other drugs, Keppra may not be for everyone because it has the possibility of severe side effects.


Ondansetron is an antiemetic (antinausea) medication. This medication has been studied as a possible treatment for anxiety experienced during benzo withdrawal. However, more studies are necessary before ondansetron can be widely prescribed for this purpose, as it can have potential cardiac side effects.


Many anticonvulsants have been studied for benzo withdrawal, including lamotrigine, valproic acid and carbamazepine. Many are mood stabilizers that can benefit those undergoing benzo withdrawal. While each medication in this class works differently, they all work to decrease excitability in the brain. This change in the brain reduces the chances of seizures. Unfortunately, many of these drugs require close monitoring and have side effect profiles that may restrict their use.
