How Long does Klonopin Stay in Your System?

Most benzodiazepines, like Klonopin, stay in your system one to two days. Although it could be longer or shorter depending on how much you weigh, how much you have taken, how long you have been taking it, and what you eat and drink. If you are worried about a drug screening and it is prescription then simply tell the lab doing the screening what you are on. That way if they find it they know it is medication a doctor has given you.
