For Fibromyalgia "It was very helpful for the spasms in my neck, shoulders, back, and hips. It took a while before the muscles released. I weaned myself off the medicine, and within 2 weeks, I was experiencing severe pain again. I'm back on now. I take 10 mg at night. It does make me tired in the morning, but it's worth it. I would recommend this for back pain and spasms. It helps to take it consistently."

For Muscle Spasm "I use Flexeril for muscle spasms that I have in my left arm and shoulder. One of the side effects of this medication is that it causes severe drowsiness. Once I take the medication, I must go to bed immediately. I am able to sleep through the night where before the spasms would wake me throughout the night. When I first began to take the medication, I found that I was very tired when I awoke in the morning. To combat this, I go to bed about two hours earlier. This is appearing to work out well. Now I awake rested and free of tightness, aches, and pains."

For Muscle Spasm "For context, I had an issue with my hip for about 2 months that was diagnosed as SI joint inflammation; I also have several chronic conditions. I was prescribed a Medrol dose pack and 5 mg Flexeril three times daily as needed for muscle spasms. Because of what I do for work, I have only been taking it before bed. The cyclobenzaprine makes me mildly tired, blocks most of the pain signals, and I wake feeling energized with a little bit of dry mouth. The troubling side effect is the weird dreams. They are mundane in nature but take weird and violent turns. In one dream, I was at work and was almost killed by a new coworker who turned out to be a serial killer; in another dream, I had bought a house and was moving things in, but now had to take care of some $8k marine fish that was left behind; and in another, I was in a panicked frenzy looking for my socks so I could go home. I don't mind the dreams once I wake up and realize they are dreams; it's just a little jarring in the moment."

For Muscle Spasm "Stay away from this garbage. I was stupid enough to try it for 3 days, 10 mg before bedtime. All those days, I was like a zombie. Dry mouth. Crazy dreams. Constant nausea. Stomach stabbing pain. No energy at all. Sleepy during the day and crazy at night. I don't know who's writing positive reviews, maybe pharma people, lol. Do your research. Stay away from this drug!"

For Migraine "I have used Flexeril for back pain but took one the other night because I had a migraine and couldn't sleep. I've never had relief from any migraine, so I was amazed when, after about 2 1/2 hours, I got out of bed and felt OK to move around. After another hour or two, I was feeling drowsy, so I ended up going to bed, but I was happy to discover that Flexeril helped my migraine. It does make me VERY sleepy, so I only take it when I don't have much to do the next day. I usually feel lethargic the day after."

For Muscle Spasm "5 or 10 mg works for muscle spasms, but dangerous if taken during the daytime. Caused uncontrolled drowsiness, deep sleep, difficulty waking up, constipation, blurred vision, and sudden unbearable headaches, leaving me unable to function. (5 or 10 mg doses had the same effects.) Lost a new job just 2 months after starting due to not realizing it was this medication's side effects of blurred vision, migraines, and exhaustion. I was unable to keep up with the workload and didn't relate it to Flexeril because I had been on it many years ago when I was much younger. I tried to explain to my PCP, but some docs just don't listen. I have since stopped Flexeril, no more headaches!"

"It's amazing to me that so many people feel this is a strong medication. I took 10 mg Flexeril for carpal tunnel a few years ago and felt absolutely nothing. No lethargy, no sleepiness, no relief of symptoms. I also tried Soma, which didn't help either. My doctor finally switched me to a real, well-known, tried and true muscle relaxant-diazepam (Valium) 10 mg, which would knock most folks out. But not me, and I'm of average weight for my height. The Valium helped some, symptoms improved a bit with rest, but still not a whole lot. So, after 2 months of trying meds and hand therapy, hot wax treatments, and rest... my doc and I decided I needed to have the carpal tunnel surgery to get some relief. That's what helped the most."

For Muscle Spasm "I was apprehensive about taking this after reading the reviews, but my experience has been positive. I had jaw surgery 6.5 weeks ago, and at about 5 weeks, my left condyle slipped off the disc and stayed there (slipped TMJ disc). I couldn't open my mouth anymore without sharp pain. Swallowing hurt, talking hurt, sometimes even moving my head hurt. It was like this for 6 days before I was able to see my surgeon and get a prescription. The next day after I started Flexeril, the pain improved. The day after, I could chew a little. Today is day four, and I'm amazed at how much better my joint feels, I can open comfortably, and I'm not in constant pain anymore. The side effects for me have been minimal. Maybe a little more tired, but honestly, I hardly notice. My mouth is a bit dry too. The great irony, however, is that I still get jaw spasms. On that count, it's been completely ineffective. But they don't bother me too much, I only get a few per day, and if I open too wide."

"I've tried Flexeril before and could hardly move, my muscles seemed so weak. However, my doctor prescribed it again. I just had a knee replacement and have been doing extensive therapy, but I'm still in pain. Plus, because of my slipped disc and spinal stenosis, I could only stand for a few minutes or walk much. I only take the medicine once in a while at night, but I can't wake up the next morning, and when I do, I am dizzy and exhausted. I'm 75 years old, and once before, I received a letter from Medicare telling me that, at my age, I should not be on a muscle relaxer. I definitely slept through the night on the medicine, but know not to take it if I have to go out the next day. It does affect my breathing because of my asthma."

For Muscle Spasm "I took Flexeril for my back, and it did help, but it made me extremely tired and gave me bad cotton mouth. I would take it and be drowsy for 16 hours afterward."

For Migraine "I agree that Flexeril is helpful because it helps me relax enough to sleep when I have a severe migraine. I can only take it at home at night, though, because it makes me tired."

For Muscle Spasm "Works well for spasms in my trapezius muscles. However, makes me lethargic for the next 24 hrs."

For Muscle Spasm "It really helps with the bad headaches from surgery. Lets me relax to sleep. Sleep gives the strength I need to help heal. Only problem is once I take it, I can't do anything else, I get very tired."
