For Muscle Spasm "My doctor prescribed 10 mg Flexeril three times per day for a painful and crippling muscle spasm in my lower back. The dosage helped relax my back, but it also relaxed everything else in my body. I had difficulty controlling my extremities, as if they were detached from the rest of my body. Sometimes I didn't have enough control of my tongue to speak clearly. Sometimes I felt weak and uncoordinated, for example, I had to take my time going up and down stairs. I felt generally sleepy and spaced out most of the time, and felt thirstier than usual. I also needed more sleep than usual, 10 hours. Overall effective for helping my condition, but the side effects were a little frightening."

For Muscle Spasm "I was involved in a rear-end collision, experienced extreme neck, shoulder, and arm pain. Ibuprofen 600 mg and 10 mg Flexeril for my neck sprain, then told to stretch the muscles to keep them from locking up. I took my first dose last night, I don't even remember going to sleep, but I didn't have the pain anymore. I woke up today feeling like I have a hangover, dizziness, and my mouth was extremely dry. So, I tried to avoid taking the meds this morning for a couple of hours. Now, it is midday and the pain hasn't stopped, so I took another pill. In my opinion, Flexeril is a good pill for relaxing your muscles, especially if you're going to physical therapy. I don't recommend driving or doing anything while on this medication."

For Muscle Spasm "I was prescribed 10 mg Flexeril after pulling an abdominal muscle, which led to spasms. The Flexeril made the pain and spasms stop, but gave me severe dry mouth and made me so dizzy I couldn't get to sleep."

"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 was prescribed Flexeril 10 mg after a car accident and injuries. The first time I took it as prescribed, said three times a day, and my first dose was on my way to class at 5 pm. I parked, took my Flexeril, went to class, and within an hour, I had to leave. I felt so dizzy and nauseous, I don't know how I drove home, but thank the Lord I made it. I then took it only at night, which doesn't help when your pain is all day, but doctors refuse to put you on anything that actually helps with pain, like a narcotic that you only take as needed and not three times a day or whatever the directions are. I have gone to pain management a few times throughout the last five years since my accident. I have been given every muscle relaxer they make, and Flexeril and carisoprodol are the only two that help, but they don't recommend taking for longer than two weeks. What option does that leave daily pain patients? I didn't get the mood swings with Flexeril like I did with amitriptyline or Cymbalta. I'm on the fence with Flexeril."

For Muscle Spasm "Very helpful for spasms of the lower back. A little occasional dizziness, the only side effect, plus some drowsiness early in the course of treatment."
