Are you about to have a drug test and are wondering "how long does Klonopin stay in your system?" Or perhaps you might have a random drug test in the future? Read on to find out everything you should know regarding Klonopin, and how long it will stay in your system.

How Is Klonopin Used?

Klonopin is most commonly used to treat anxiety disorders and seizure disorders.

Anxiety disorders are a type of mental illness that cause excessive worry, fear, or stress. Common types of anxiety disorders are generalized anxiety disorder, social anxiety disorder, and panic disorder.

Seizure disorders are a type of neurological condition that cause recurrent seizures. Seizures are periods of uncontrolled electrical activity within the brain that can cause convulsions, changes in behavior, and loss of consciousness. Common types of seizure disorders include epilepsy and cerebral palsy.

Klonopin may also be used to treat other conditions as prescribed by a doctor.

The elimination half-life of Klonopin is 30 to 40 hours, meaning that after this amount of time, only half of the Klonopin you take has left your body.

If you are taking Klonopin and are subject to drug testing, it is important to know how long does Klonopin stay in your system. The length of time that it can be detected depends on the test used. The main tests which are used are urine, blood, hair, and saliva.

How Long Does Klonopin Remain in Your Urine

Traces of Klonopin can be detected in urine tests for up to a month after your last dose.

How long does Klonopin Remain in Your Blood

Klonopin can be detected on a blood test about 3 days after your last dose.

How Long Does Klonopin Remain in Your Hair

Klonopin is detected in the hair follicle tests for up to a month after you have last used it.

How Long Does Klonopin Remain in Your Saliva?

A saliva test shows the presence of Klonopin up to 6 days after you have last used it.

How Easy Is It to Become Addicted to Klonopin?

Klonopin is a potent medication, and it can be easy to become addicted to it. You quickly build up a tolerance to Klonopin, which means that higher and higher doses are needed to achieve the same effect. Being addicted can lead to severe health problems, including liver damage, respiratory problems, and coma.

Klonopin Withdrawal Risks

Quitting Klonopin suddenly can cause withdrawal symptoms. These symptoms can be mild to severe, and they can include:


This can be worse if you started using Klonopin to treat underlying anxiety, and if you had been using Klonopin in a larger dose than recommended.


Trouble sleeping is common when you first stop taking Klonopin. You may have trouble falling asleep, or you may wake up frequently during the night.


You may feel cranky, short-tempered, or just generally on edge when you go through Klonopin withdrawal.

Muscle Aches and Pains

You may experience muscle aches and pains, as well as general fatigue.


Seizures are a serious risk when withdrawing from Klonopin. If you have had seizures in the past, or if you have been taking large doses of Klonopin, you should be closely monitored by a healthcare professional during withdrawal.

It is important to taper off Klonopin slowly and under the supervision of a medical professional to avoid these withdrawal symptoms.

How Can I Pass a Klonopin Drug Test?

If you have been taking drugs, there are not any reliable methods to pass drug tests. However, if you abstain from drug use for a significant period of time prior to the test, your chances of passing increase significantly.

Dangers of Combining Klonopin With Alcohol

Klonopin is a medication that doctors use to treat anxiety and seizures. It belongs to a class of drugs called benzodiazepines. Klonopin works by slowing down the nervous system.

Alcohol is a depressant that also slows down the nervous system. When someone takes Klonopin and drinks alcohol, the effects of both drugs are increased. This may lead to serious side effects including drowsiness, impaired coordination, and slowed breathing.

Mixing Klonopin with alcohol can also lead to memory problems and blackouts. In some cases, it can also lead to coma and death. If you or someone you know is taking Klonopin, it is important to avoid drinking alcohol.

How to Sleep Without Klonopin

There are a several things you can do to help you sleep, other than taking sleeping tablets. Some small lifestyle changes can make a big difference.

First, try to maintain a regular sleep schedule as much as possible. Go to bed and get up at the same time each day. This helps to regulate your body’s natural sleep rhythm.

Second, create a relaxing bedtime routine. A warm bath, reading a book, or listening to calm music can help your mind and body wind down before sleep.

Third, avoid caffeine and alcohol in the evening. Both of these substances can disrupt sleep. Caffeine should be avoided for at least six hours before bedtime, and alcohol should be limited to one or two drinks.

Fourth, limit screen time before bed. The blue light emitted by electronic screens can interfere with sleep. Try to avoid using phones, tablets, and computers for at least an hour before bedtime.

Finally, make sure your bedroom is dark, quiet, and cool. These conditions are ideal for sleep. If you can’t control the noise or light level in your bedroom, try using a sleep mask or earplugs.

If you follow these tips, you should be able to get a good night’s sleep without taking sleeping tablets. However, if you continue to have trouble sleeping, talk to your doctor. There could be an underlying medical condition that needs to be treated.

Getting Klonopin Addiction Treatment

If you or someone you care about is addicted to Klonopin, it's important to get treatment as soon as possible. Addiction to Klonopin can lead to serious health problems, including overdose and death.

Treatment for Klonopin addiction usually involves a combination of detoxification, counseling, and support groups.


Detoxification helps to rid the body of the drug and can be a difficult and uncomfortable process. Detoxification involves both physical and psychological symptoms of withdrawal. If you attend a rehab, you will be professionally tapered, which will eliminate much of the discomfort and danger caused by withdrawal.


Counseling is an important part of addiction treatment. Counselors can help you to understand your addiction, work through the underlying issues that may have contributed to your addiction, and develop a healthy lifestyle.

Support Groups

Support groups can provide social and emotional support during addiction treatment. They can also help you to develop a healthy lifestyle and provide accountability after you have completed treatment.
