Hello,

The Zanaflex contains Tizanidine and is used as antispastic in MS and spinal injury. The half life of Tizanidine is 2.5 hours but its metabolites have half life of 20-40 hours. So the single dose will take 80-90 hours to get out of system and in hair follicle test it will take 90 days.

Take care
