How long before ONE klonopin cannot be detected through urine test?

I had taken one klonopin before riding roller coasters, it helps to relax me(I don't do well on coasters.) I have a urine test 6 days after taking just one of them. Do you think I will be safe. I am not a regular user by any means. Thank you!!

Problem there is I have no prescription, my mother gave one to me :(

Klonopin is usually out of your system in about thirty to forty hours so I'd say you're safe. But in the future remember never take someone else's prescription drug because you never know how you're going to react to it. So either stay away from roller coasters or try taking an over the counter medication like diphenhydramine which is completely out of your system in twenty-four hours.
