muscle spasm
"I took this among many other muscle relaxers for spasms and pain. Not sure if Xanax would interfere but it did nothing for me at all. Neither did many others. Best success was with Flexeril once you get past the first week of feeling like butter and sleeping like a rock. Was prescribed 3 10mg a day...no way, would have slept all day. Take one about 2-3 hours before bed and you are gold."
