As a Law Enforcement Officer, I am randomly tested at work. I have been prescribed Tizanidine HCL 4mgs, with instructions to take 1/2 to 2 tablets at bedtime. This medication was prescribed to me for the muscle, joint, and RA pain associated with my SLE Lupus. I am in the midst of the worst flare up since being diagnosed several years ago. I have made it very clear that I am never to be prescribed any type of narcotics- under any circumstances. I will just deal with the pain. I was assured- this medication would be fine. IS IT? I AM NOW CONCERNED???
