My dr has prescribed Flexerall 10 mg and has 3x a day., I was taking 1-2 pills at bedtime. I went to get my prescription, and there is a script for zanaflex 1/2 pill at bedtime. Looking at them the are both muscle relaxers. I have fibromyalgia, and CIDP (which is a nerve disorder) I do have muscle spasms, but he didnt tell me he was sending this in. it seems like it would be better to use just one?? Just looking for an answer till I can call my dr in 2 days when he will be in the office..
