Muscle Spasm
"Seems to be working a lot better than other muscle relaxers I&#039;ve been prescribed. My doctor prescribed 500 mg tablets and to take 1-2 tablets every 8 hours as needed (PRN). I usually have to take 2 tablets in the morning, 1-2 late afternoon, and ALWAYS take 2 at bedtime or I&#039;ll be up all night in pain and constant spasms in my lower back into my buttocks. I also take a long acting narcotic and an instant release narcotic. I never experienced this type of pain until I delivered my son 4 years ago. I did receive an epidural which is the only thing I can think of that may have caused all this pain and spasms."
