Klonopin (clonazepam) is a long-acting benzodiazepine drug that can be detected in a urine test for three to 30 days after your last dose. The amount of time Klonopin stays in urine will depend on the dose and duration of use, among other factors.

How Long Can Klonopin Be Detected In Your Urine?

Klonopin, the brand name for clonazepam, is a long-acting benzodiazepine drug that can stay in urine for anywhere from three to 30 days after your last dose.

Klonopin can be detected in urine unchanged or by its primary metabolite, 7-aminoclonazepam. Urine screenings are the most common drug testing method used by doctors and employers.

Detecting Klonopin In Urine

On average, Klonopin can be detected through a urine screening for 3 to 30 days after the last use.

Factors That Can Affect How Long Klonopin Stays In Urine

Not all bodies will process Klonopin at the same rate.

The actual timeline for how long Klonopin stays in your urine will depend on multiple factors:

  • Dose: Higher doses of Klonopin will take longer for the body to eliminate from urine compared to small or moderate doses of Klonopin.
  • Frequency and duration of use: Taking Klonopin regularly for a long period can increase drug tolerance and cause drug dependence. Both can lengthen the detection time of drugs in urine.
  • Metabolic rate: People with a slower metabolism will have longer detection windows than people with a fast metabolism, on average.
  • Method of use: Injecting or smoking drugs can result in shorter detection windows compared to snorting or swallowing drugs.
  • Liver function: Impaired liver function may increase the amount of time it takes for Klonopin to leave the urine. This is because Klonopin is metabolized primarily by liver enzymes.
  • Polydrug use: Taking other drugs in addition to Klonopin may affect how long it takes for the body to clear Klonopin from the urine.

How To Get Klonopin Out Of Your System

Getting Klonopin out of urine is a common concern of people who abuse Klonopin or are addicted to it.

Getting Klonopin out of your system takes time. If you’re dependent on Klonopin, stopping your use will require gradually tapering your dosage. Do not try to stop taking Klonopin all at once.

Drug detox programs can provide the most supportive setting for people who are addicted to Klonopin to get off of the drug safely.
