Clonazepam Withdrawal

Man in clonazepam withdrawalClonazepam (Klonopin) is a benzodiazepine drug prescribed to manage panic attacks and seizure disorders.1,2 When taken as directed, clonazepam is generally safe. However, regular use is associated with tolerance and physical dependence.

Over time, the body adapts to the presence of clonazepam and will require higher doses or more frequent doses to produce the desired effects.4 With frequent use and higher doses, the body begins to function normally only when clonazepam is present, which is known as physical dependence.3,4 At this point, when the person reduces their clonazepam use or stops completely, withdrawal symptoms will appear.3,4

During withdrawal from clonazepam, a person may experience symptoms ranging from mild to severe, which can last up to two weeks.1,5,10 The greatest immediate health risk associated with clonazepam withdrawal is the possibility of seizures.1,6 For these reasons, clonazepam withdrawal should always be managed by medical professionals to increase patient comfort and reduce potential danger.7

Clonazepam withdrawal symptoms usually begin within a day or two following the last dose. The symptoms will vary based on the individual, the dose of the medication, and how long the person has taken the medication. When symptoms begin, the individual may experience:1,5,6

  • Anxiety.
  • Muscle tension and pain.
  • Insomnia.
  • Tremors.
  • Low mood.
  • Poor memory and concentration.
  • Restlessness.
  • Seizures.

These symptoms may resolve quickly but can continue for up to 2 weeks after last use.10

Withdrawing From Clonazepam: Treatment Methods and Options for Help

Clonazepam withdrawal symptoms can be reduced by tapering.

Clonazepam withdrawal symptoms can be reduced or prevented with a gradual reduction of the dose.5,6 This process is called tapering or weaning. Often, a person will first be switched from clonazepam to another long-acting benzodiazepine, such as diazepam, or a long-acting barbiturate, such as phenobarbital.5,6

In either case, the treatment providers will determine a dose of the long-acting medication that is equivalent to the amount of clonazepam the person used and establish stability at that dose.5,6 From there, the provider will gradually reduce the dose and frequency of the medication. This process can take days, weeks, or months depending on the person’s needs and the withdrawal symptoms the person experiences when the dose is lowered.5,6

For some, completing the withdrawal process at an inpatient clinic may be more comfortable than withdrawing at home, because physicians can help people manage symptoms as they emerge. Detoxing in a clinic also prevents access to clonazepam and minimizes relapse.

On the other hand, people that require a long taper may not be able to remain away from home for that length of time, which makes outpatient more appealing.

The recommended course of action will depend on:

  • The person's level of dependence.
  • Whether the person has a history of withdrawal complications.
  • The existence of other physical or mental health conditions.
  • Abuse of other drugs or alcohol, and their level of support.

Detoxing, Addiction Treatment, Rehab, and Recovery

Detoxification is an important part of recovery, but it alone is rarely enough to maintain a drug-free life.8 Fortunately, there are many treatment options to consider following detoxification.8,9

  • Residential options.

    • Therapeutic communities. Long-term treatment with structured, intense programs.
    • Shorter-term residential. Transitions people from detox to other forms of ongoing treatment and lasts for several weeks.
    • Recovery housing. Supervised housing that helps people gain their independence after rehab.
  • Outpatient options. Outpatient treatment is flexible and offers a range of programs that can include 30 hours of treatment per week down to one hour per month.
  • 12-step and other support programs. While receiving professional treatment from counselors and physicians, people in recovery should also consider meeting with support groups such as SMART Recovery or Narcotics Anonymous. For many people in recovery, these types of groups eventually become primary sources of ongoing support.

Regardless of the treatment setting, the professional will conduct individual or group counseling sessions that use several forms of therapy, including the following:8

  • Cognitive-behavioral therapy (CBT) to help people recognize, avoid, and cope with problematic situations.
  • Family therapy to improve the entire family unit.
  • Motivational interviewing (MI) to build internal drive and motivation to remain drug-free.
  • Contingency management (CM) to provide tangible rewards as positive reinforcement for continued abstinence.

These treatment styles can provide introductions to different stress management techniques as well as help to address any underlying mental health conditions. Rehabilitation, whether it is provided through inpatient or outpatient facilities, can also assist people with social or interpersonal issues, housing and career options, relapse prevention, family difficulties, and legal issues.
