Expert: Dr. David replied 3 years ago. clonazepam has a half life of between 20-50 hours. that means that there is a pretty good chance that in 2.5 days it might be detected in your urine.
21 Apr 2010. vick222, I take clonazepam 2mgs. 2x a day for well over a year they don't begin leaving your system for even approx. 48 hours.They can take a little as 5 days and as long as twenty.You have to factor in certain things like your dosage and how long you have been on them. Some other benzo's (like xanax) will leave your system about 8-12 hours since your last dose as they have a very short half-life.
