muscle spasm
"I was prescribed this medication for muscle pain related to rheumatoid arthritis and chronic tendonitis.  Personally I'm VERY sensitive to this medication and suffer the "rare: side effects slurred speech, hallucinations  (only at night) disorientation  (I've gotten lost in my own room twice when I take 4 mg) low heart rate. The highest dose I have taken is 8mg with Xanax for my anxiety,  once I stayed awake although drowsy, I watched a movie; the second time I woke up in ICU for bradycardia, hypotension and change in level of consciousness. Despite talking this daily for 2 months, I still have side effects. My husband says this medicine makes me drunk. I have been taking 1mg at a time.  It does work well."
