Cyclobenzaprine: Flexeril is not tested for in a urine drug screen. Try not to take other's medications in the future. Take care.

Cyclobenzaprine: http://www.rxlist.com/flexeril-drug/clinical-pharmacology.htm Half life is about 18 hours (up to 37 hrs) so by 10 days , you should be through 7-13 half lives so the amount in your blood should be negligible. So would not worry. Do not take any more unless you have a prescription( if you have a valid prescription, then it usually does not cause problems with drug testing). f/u/ w/ doc.
