muscle spasm
"I was prescribed Lorzone recently by a pain specialist when I explained that all other muscle relaxants I have previously used were too sedating. I was pleased to find that though it is a 'new' medication (presumably repatented, since Paraflex was around since the 1990's), my insurance covered its generic form, Chlorzoxazone. 



In my experience, this is not a medication that is going to alter your mental state or give a drowsy effect; I do notice significantly reduced muscle spasm activity when taking it and none of the negative effects so common with other medications of its class. It does exactly what is expected and no unwanted side effects for me."
