How Long Does Clonazepam Stay in Your System?

Specialists consider clonazepam as an effective treatment for bipolar disorder in the mania phase, anxiety disorders, obsessive-compulsive disorder (OCD), and other mental conditions. It also helps with seizure relief. It occurs thanks to the medical features of clonazepam. This benzodiazepine medication is a long-acting tranquilizer and has both psychological and physical effects. [1]

Clonazepam strongly influences the human mind and psychological state, so it’s sold only by prescription. It may also be on the list of medicines sought by different drug tests. That’s why some people search for answers to the question: how long does clonazepam stay in the system? As an answer will differ depending on the medication dosage, we provide you with a detailed overview.

How Long Does It Take for Clonazepam To Get Out of the System?

Clonazepam’s half-life is usually 30 to 40 hours. This means that it takes up to 2 days for half of the medicine to leave the body. The final elimination of the drug takes much longer, depending on many factors. Among them are dosage, personal patient traits, and test type. Each of them influences the time clonazepam lasts in the system.

There are many test types, all of which target substances from particular body fluids and parts. All of them have their detection windows, which should be considered when planning drug test passing.

• Saliva test. Clonazepam doesn’t linger in the saliva, going further into the stomach. Because of that, a relatively small number of the medicine’s molecules stay here and can be revealed during tests. Therefore, it is no wonder that the detection window for clonazepam is narrow, usually 2-6 days. Saliva tests are often used for quick assessments.
• Blood test. The revealing time for this body fluid can be even shorter than for saliva, nearly 1-4 days. This is because of the high medication absorption rate into the blood. Blood tests are also beneficial in medical settings for immediate results.
• Urine test. The 10-panel and 12-panel drug tests, popular screening methods used to detect the presence of multiple drugs, including clonazepam, use urine samples to reveal the substances. Usually, tests may detect the medicine for up to 14 days. [2]
• Hair follicle test. These tests have the most extended detection window. It takes the time of growing and falling out of a hair follicle up to 90 days. Nevertheless, such tests are rarely made because they can’t pinpoint recent use. [3]

Besides the test types, many other factors impact how long it takes to get clonazepam out.

• Metabolism and body composition. Metabolism, among other things, is the capacity to absorb different substances in the organism. This also concerns clonazepam. The higher the metabolism, the quicker the drug is eliminated from the system. It’s the opposite with fat percentage in the body. Its high rates mean that the drug starts storing in fat tissues, slowing its removal.
• Age and health. They are also significant factors in clonazepam’s elimination. Younger and healthier people usually get rid of the medicine faster.
• Use of other substances. Taking other medications or alcohol alongside clonazepam may impact its metabolism. At the same time, some drugs enhance liver performance, which may also speed up the medicine’s elimination.
• Frequency of use. The simple math: consistent use of clonazepam may cause its accumulation in bodily tissues. The detection window will grow because of that. [3]

How Long Does Clonazepam 0.25 mg Stay in the System?

Clonazepam aims to help with various mental issues. Their symptoms and severity distinguish them and consequently require different doses of the medicine. Increments of 0.25 mg are one of the basic doses that can be used for treating panic disorder, for example. Such an amount of the medicine usually takes 6 to 9 days to get out of the body entirely. However, these numbers highly depend on many factors we noted before, like age, health, test types, etc. [4]

How Long Does Clonazepam 0.5 mg Stay in the System?

Clonazepam 0.5 mg is another widespread dose of this drug. It can be used, for instance, for treating seizures. It usually has the same elimination period of 6-9 days as the 0.25 mg dose. It should be mentioned that these numbers are approximate and may vary from person to person. The extending of window detection for drug revealing comes rather from the persistent use of clonazepam than from its dosage. [4]

How Long Does Clonazepam 1 mg Stay in the System?

The numbers for 1 mg of clonazepam are pretty much the same as for 0.25 and 0.5 mg. An increase in the drug elimination time may begin after 2 mg. Still, long-term use of clonazepam plays a more significant role in this than a high dose itself. [4]

Speaking about the medicine doses, the problem of overdose should be discussed. It appears when patients use clonazepam not as it was prescribed. Users may take higher doses or do it more frequently than it was meant for. Anyway, it may lead to various health issues. They range from relatively light symptoms like drowsiness, confusion, muscle weakness, and slurred speech to more serious ones. Among them can be cardiovascular issues, low blood pressure, and others.

Respiratory depression should be highlighted as a potential consequence of clonazepam overdose. As it is a drug with a powerful impact on the central nervous system, its excess in the body may cause dangerously slow breathing. Because of this patients should follow the doctor’s instructions carefully to avoid undesired effects. [5]

Clonazepam has a strong sedative effect. Specialists consider it a practical drug for treating some mental issues and seizures. On the reverse side of it, clonazepam as a benzodiazepine medication can be used only with a prescription. It also often includes different drug testing to be revealed. That’s why people seek to understand how long does clonazepam stay in the body. It varies a lot, depending on different personal factors like age, health, dose, type of test, etc. Reach out to URP Behavioral Health for safe and effective treatment of mental health concerns.
