Im currently on probation and i have a hard time sleeping sometimes, my grandma gave me a whole bottle of prescription tizanidine 4mg, would that show up on my monthly urine test? my wife told me no because it wasnt a narcotic?

Unlikely, but.... This med is not a controlled substance and not likely to show up on any routine screening. However, using a prescription medication when it is not prescribed for you may get you in trouble with some authorities if they find out. It also has a potential to trigger addiction. You may want to discuss its use with your doc.

Not addressing your question directly, but to help with sleep, you need to attend to good sleeping practices. Sleep hygiene: Visit this site for info on this topic https://www.cdc.gov/sleep/about_sleep/sleep_hygiene.html Wish you good health!
