Dangers of Benzo Withdrawal

Withdrawal from severe benzodiazepine dependence can be dangerous—even fatal—without medical supervision.1

This page will go over the potential issues someone may experience when they give up benzodiazepines and how medical detox can help make the withdrawal process safer and more comfortable.

Benzodiazepine Withdrawal Symptoms

The longer benzos have been taken and the higher (or more frequent) the dose increases the likelihood of experiencing severe benzodiazepine withdrawal symptoms.3 The duration of drug action is also a factor that influences the severity and duration of withdrawal symptoms.1,3 Even people who have been taking benzodiazepines as directed by a medical professional can experience withdrawal when they reduce or cease regular use.1,3

Benzodiazepine withdrawal can bring about a wide range of symptoms such as:1,3,4

  • Sweating.
  • Increased heartrate (greater than 100 beats per minute).
  • Anxiety.
  • Agitation.
  • Insomnia.
  • Hand tremor.
  • Perceptual disturbances (i.e., hallucinations).
  • Seizures.
  • Delirium characterized by disturbances in consciousness and cognition, with visual, auditory, or tactile hallucinations.

 Some people also experience anxiety and depression for several weeks or months following acute withdrawal.

Is Withdrawal from Benzos Deadly?

In severe cases, especially when untreated, benzodiazepine withdrawal may be fatal.1,4

Those at risk of experiencing increased severity of withdrawal symptoms include:1,5,7

  • The elderly.
  • People who misuse alcohol.
  • People who take other sedatives or sleep aids.
  • People who take opioids or are experiencing opioid withdrawal symptoms.
  • Individuals with a paternal history of alcohol use disorder.
  • Individuals with a history of seizures.
  • People with psychiatric disorders or physical health issues.

Withdrawal from benzos can carry serious risks that should be considered when deciding to discontinue or reduce use. A medically supervised detox can mitigate the risk of experiencing severe withdrawal symptoms and help to ensure a person is as safe and comfortable as possible.1 

Can I Detox from Benzos Cold-Turkey?

Detoxing from benzodiazepines cold turkey—i.e., abruptly stopping them without any medical supervision—can lead to withdrawal symptoms, some of which may be severe and life-threatening.1

Medical detox can mitigate the risk of patients experiencing seizures and other severe symptoms, as well as make the withdrawal process both safer and more comfortable.1 Medical detox can also help prepare someone for entry into more formal inpatient or outpatient drug rehab treatment.1

How to Safely Withdraw from Benzos

Many individuals benefit from  inpatient or outpatient detox programs which can help reduce the likelihood of serious adverse or life-threatening reactions.1

Medical detox may include the prescription or administration of medications to reduce the risk and potential severity of withdrawal symptoms.1

Some facilities, like Laguna Treatment Center, also provide behavioral therapy, psychoeducation, and peer support, providing a seamless link to continued treatment in addiction rehab. Detox alone is rarely  sufficient to help addicted individuals achieve long-term abstinence. Formal addiction rehab treatment can help address the social, psychological, and other factors that may contribute to someone’s substance use disorder.1,6

Continued addiction treatment after detox may involve:6,7

How Long Do Benzo Withdrawal Symptoms Last?

The timeline for when withdrawal will begin and how long it will last is dependent on various factors, including the regular dose as well as the half-life of the benzodiazepine.1,3

Withdrawal from:3,8

  • Shorter-acting benzos (e.g., Xanax, Ativan, Restoril) may begin within hours of stopping use and improve significantly by the 4th or 5th day.
  • Longer-acting benzodiazepines, (e.g., Klonopin, Valium, Librium) may not start for 1-2 days or more and may last 3 or 4 weeks.

In some cases, people may experience discontinuation symptoms for weeks or even months after acute withdrawal symptoms have subsided. Some may experience the reemergence of symptoms for which the benzo was originally prescribed (e.g., anxiety or insomnia). These reemerging symptoms sometimes reoccur with greater severity following benzo discontinuation.7

A small proportion of people may experience prolonged withdrawal following discontinuation of long-term benzodiazepine use. Symptoms of prolonged withdrawal are irregular and unpredictable, and generally include waxing and waning symptoms including: often mimic those of anxiety and mood disorders, such as:

  • Insomnia.
  • Anxiety.
  • Perceptual disturbances.
  • Sensory hypersensitivities.
  • Tremor.
