muscle spasm
"I have Multiple Sclerosis and was excited to begin Zanaflex as soon as it was approved in 1996. I had studied it for quite some time as it was in use in 47 countries before the US. I Love it and have had great results to this day with it. I'm not sure if it is very well presented or explained to patients; however, this is a very unique skeletal muscle relaxant & it actually targets the actual nerves of the patient. When you begin treatment it is important to note that for the 1st 2-3 weeks it is taking effect in your system. Great medicine!"
