For Muscle Spasm "Zanaflex is great for muscle spasms as I have them from Osteoarthritis in my spine, also spinal stenosis. If you are on any heart meds, please use the interactions checker because it may cause severe drops in blood pressure. I am taking Lisinopril, Hydrochlorothiazide, and Metoprolol for heart arrhythmias and my blood pressure was dropping to dangerous levels. All of my specialists knew what medicines I was taking, but none of them noticed the interactions. I checked them myself here at Drugs.com and found the RED FLAGS myself, so be careful."

For Muscle Spasm "I've been on these for about 8 years. They work well on low back pain, DJD, and a bulging disc in my neck. Along with other painkillers, they work well, but don't drive while on them. They do make you sleepy quickly, and they also tend to lower your blood pressure, making you dizzy when standing up. You can get a good night's sleep on them. I take one 4 mg tablet 2 times a day."

For Muscle Spasm "I was prescribed Zanaflex for muscle spasms and to help me sleep. I have been diagnosed with fibromyalgia, osteo/degenerative arthritis, sciatica, and an unspecified autoimmune disorder. It was prescribed as 3-4mg tablets at bedtime but that was too high a dose for me. Sometimes, I have the side effect of really low BP, although I have been taking high BP meds for 5+ years. It doesn't happen all the time when I take it but it is very scary when it does happen. I have blackouts, feel incredibly high, and can't hold my eyes open at times. The blood pressure drops have happened in the past when I was not on Zanaflex, but this medication just seems to make it worse and I am not going to take it anymore. The side effects are too scary."

For 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 the ICU for bradycardia, hypotension, and change in the level of consciousness. Despite taking 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."
