What is Klonopin (Clonazepam)?

High-potency benzodiazepines, such as clonazepam (Klonopin), commonly treat panic disorder (PD) because of their prompt onset of action and good tolerability.  However, there is concern about their potential to cause withdrawal symptoms.

Klonopin detox at a medically supervised facility can lessen the severity of the symptoms and make the withdrawal process significantly more accessible and more comfortable to endure.

Clonazepam, alone or in combination with other psychoactive substances, can lead to distressing effects on health, such as motor and cognitive impairment, sleep disorders, and aggravation of mood and anxiety disorders.

Prolonged use of clonazepam may lead to physical dependence and tolerance.  There is, therefore, a need to find safer therapeutic alternatives for treating seizures and anxiety disorders. 

How long does Klonopin stay in your System?

A medication called Klonopin is used to treat panic disorder and specific kinds of seizures. It can stay in a person’s system for weeks and has a long half-life.

According to studies, Klonopin could be found in the body for up to a month in a urine test, up to 28 days in a hair test, and up to 5 or 6 days in a saliva test.

Klonopin abuse can cause physical dependence and addiction. People who are addicted to the substance should work with a doctor or addiction treatment center to gradually reduce the dose (taper), as stopping suddenly can be risky and even fatal.

The duration of Klonopin in your blood, urine, saliva, and hair

Compared to other benzodiazepines, Klonopin or clonazepam is a long-lasting benzo. This means that it can take longer for the drug to be eliminated in the body. The duration of how long clonazepam will remain in your system may vary.

The exact duration is influenced by multiple factors including the user’s age, health, body mass index, and liver function. Other factors that may affect the duration of the drug in the body include the dosage taken, the frequency and duration of use, and whether the user is taking other medications. The length of time the drug can be detected in the body will also depend on the method of drug testing that will be administered. There are four common drug tests that are usually used for Klonopin: urine test, saliva test, blood test, and hair test.

How long does Klonopin stay in Urine?

How long does Klonopin stay in Urine? Urine testing for Klonopin is commonly done because it is lower in cost compared to other types of drug tests.  When you are being tested for Klonopin, the urine test will look for the metabolite called 7-aminoclonazepam, which is the byproduct the body creates when clonazepam is processed.

This metabolite can be detected in the urine after a few hours of taking the drug. It can last in the body for a minimum of (5) five days to around 21 days or even longer.

How long does Klonopin stay in Saliva?

How long does Klonopin stay in Saliva? Saliva tests are not usually used to detect Klonopin because not only are they unreliable, but they are also quite expensive compared to other tests.

After a few hours of taking Klonopin, it can be detected in the saliva up to (5) five days after use. Klonopin metabolites can be detected for around (6) six days.

How long does Klonopin stay in Blood?

How long does Klonopin stay in Blood? When talking about the duration of the drug in the body, the term “half-life” often crops up. The half-life of a drug is the measure of time it takes for your system to eliminate half of the amount of the substance you took. Compared to other drugs, Klonopin has a very long half-life which is 30 to 40 hours.

In a blood test, clonazepam or Klonopin can be detected in the blood for 2 half-lives or more, which amounts to around 80 hours or (3) three days.

Klonopin Hair Test

It can take several days after taking the drug before you can test positive for Klonopin in a hair test. However, the drug can be detected for 28 days to 120 days in your hair. Klonopin hair tests are also not very consistent.

How to get Klonopin out of your system?

If you are about to undergo a drug test, the best way to eliminate the drug from your system is to totally stop using the drug. Do not use fake pee in a drug test or other dishonest means. If you feel that you are addicted to the substance, seek professional help to safely detox and get treated for your addiction. If you or a loved one is struggling with substance abuse, help is available.

Klonopin’s Long Half-Life

Based on the estimation of clonazepam’s 30- to 40-hour half-life, Klonopin is likely to remain in your system for approximately six to nine days after your final dose. Both Klonopin and its metabolite 7-amino-clonazepam are detectable in the urine for about four days after the last use.

Signs & Symptoms of Klonopin Withdrawal

(How Long Does Klonopin Stay In Your System?)

The symptoms of Klonopin withdrawal are similar to alcohol withdrawal. You can expect to feel edgy, irritated, and flu-ish. These symptoms may come and go. Symptoms that may have originally driven you to start taking Klonopin, such as anxiety and insomnia, may come back with a vengeance.

Unfortunately, it is impossible to predict exactly how Klonopin withdrawal will affect you. Even if you’ve gone through it before, your next time could be completely different.

Generally speaking, the severity of your symptoms will depend on the amount of Klonopin you’re currently taking, how long you’ve been taking it, and whether you’re mixing it with other drugs or alcohol.

Side effects of Klonopin abuse

(How Long Does Klonopin Stay In Your System?)

Klonopin works by depressing the central nervous system and when it is abused it causes a short euphoric high followed by an intoxicated stupor, causing sleepiness in over ⅓ of people who use it. Any use of Klonopin without prescription or in higher than recommended doses is considered abuse. Some people who abuse Klonopin will crush the tablet form of the drug into a powder and snort it to increase the drug’s effects and speed at which they are felt. 

After the initial euphoric high, people who abuse Klonopin in large doses or over long periods of time can expect to experience the following symptoms:

  • Dizziness
  • Vertigo
  • Fainting
  • Numbness
  • Impaired cognition
  • Confusion
  • Slow reaction time
  • Impaired judgment
  • Reduced libido

Getting Treatment for Klonopin Addiction

(How Long Does Klonopin Stay In Your System?)

Once an individual becomes addicted to Klonopin, it can be very challenging to stop. Individuals who use the drug regularly and for long periods of time often encounter withdrawal symptoms when they stop using, which is why they persist using even if they want to stop.

Healing from clonazepam dependence is possible. The first step to obtaining help is acknowledging to yourself that your Klonopin use is no longer beneficial. It’s easy to downplay the gravity of your addiction. Many people find it hard to face their addiction.

By entering an addiction treatment facility, you’ll benefit from medically-supervised detox, prescription management, remedy of underlying mental health disorders, group and individual therapy and an aftercare treatment plan.

What are the dangers of taking clonazepam?

Warnings: Clonazepam has a risk for abuse and addiction, which can lead to overdose and death. Taking this medication with alcohol or other drugs that can cause drowsiness or breathing problems (especially opioid medications such as codeine, and hydrocodone) may cause very serious side effects, including death.

What clonazepam does do to your brain?

Clonazepam slows down your central nervous system (CNS) and releases tension in your body. This can ease ruminating thoughts leading to severe anxiety and panic disorders. It can also inhibit muscle spasms and CNS activity associated with seizures. Klonopin can make you feel somewhat euphoric and uninhibited.

How much clonazepam can you take in a day?

Adults and children 10 years and older—At first, 0.5 milligram (mg) 3 times per day. Your doctor may adjust your dose as needed. However, the dose is usually not more than 20 mg per day
