@Terrar ,

Based on my research, zanaflex (tizanidine) may take anywhere from 3 to 5 days to get completely out of your system. This isn't counting your hair follicles though, which they say can take up to 90 days.

I also read that even though tizanidine has a short half life of 2.5 hours, its metabolites have a significantly longer half life ranging from 20 to 40 hours; making a single dose last as long as 80 to 90 hours in your system.

@Shelby (post #1):

With regards to a drug panel, my understanding is that because this medication is not a controlled substance, it's likely that it wont even be checked for in a UA.

How long have you been on this medication for?
