How Long Does Klonopin Stay In Your System

Hi, I was wondering how long Klonopin stays in your system? I take up to 1mg daily for anxiety. One of my issues even before I took Klonopin was fatigue. Would it do any good to take it before bedtime? My CNP has mixed opinions on this, and I don't know how long it stays in my system anyway. Any information would be great.



Klonopin has a very long half-life of 20 - 50 hours, depending on age and health. Since the low end of that half-life is under 24 hours, it's usually taken twice a day to keep the amount in the system level. The "normal" dosage range listed for anxiety is .25 to .50 mg twice a day, but keep in mind that this is a recommended dosage, and doctors often need to adjust that some for their patients' needs.

Hope this helps,
