I can't lie, it's a nice buzz, but, who's got time to sit around all day and ask yourself why you just took a "useless pill!"

 5  fibromyalgia I started taking flexeril ages ago for pain from fibromyalgia. Back then, I could only take it at bedtime, as it turned me into a zombie. But it allowed me to get a good nights sleep, and I woke up fine in the morning. However, if I tried to take it during the day, it would knock me out. After years of taking it PRN, it no longer knocks me out, which I actually miss, because I'm having trouble finding something that does that a dr will continually prescribe me. But now that I can take it whenever... I have a reverse curve in my neck from multiple whiplash injuries, and flexeril is the ONLY thing that will take away my neck pain once it starts (driving long distances really aggravates it). It works absolute wonders for that. After taking for 7 yrs PRN though, I do need 20 mg or occasionally even 30 to kill the pain. F 29 7 years

 1  nerve pai This was the most severe drug allergy I've ever had. I woke in the night to severe sweating clamminess that changed to extreme heart tightness/pounding. I almost fainted, and then felt nauseous with chills. We almost called paramedics and then symptoms started to reduce. It scared me terribly and I'm an otherwise healthy adult. I realize it was severe but if thus can help anyone then I want it shared. F 40 2 days

 3  Degenerative Disc - hip & foot pain Very frequent hot flashes and DAILY HORRIBLE EXCESSIVE AND EMBARRASSING SWEATING!!!! Also occasional numbness in my left hand, leg and foot. Taking due to degenerative disc that has caused a domino effect of pain on the right side of my body to include shoulder, hands, hip, knee and heel of foot. This medicine has done wonders to the pain, however the side effect of the EXCESSIVE SWEATING is far too embarrassing to continue. I also suffer with daily headaches and it has really eased that pain as well. F 41 6 days

 3  sciatica slight swelling of feet and ankles. Mild drowsiness. I have lower back issues and I take Flexeril to help with the pain. I am prescribed 10mg and I DO NOT have any of the same side effects as other users on this site. No hallucinations, no coma like sleep, it just takes the edge off the pain so I can go to work and take care of my daily responsibilities. Just be careful and you will be fine. Do not take more than recommended and start with a half dose on a day when you can stay home to see how it affects you. After a few consecutive days of taking Flexeril I do get swelling of the feet and ankles, but that goes away as soon as you stop taking it. F 36

 1  severe muscle tension Relieves tension but is Horrible and frightening! Unlike everyone else, it seemingly slows my heart rate severely which corresponds with the sensation of my body slowing down so much it feels like a body wide shut down. I only take half of a 10mg pill before bed when the pain is completely unbearable (I'm allergic to all opioids) and have startled myself awake several times from not breathing which triggers anxiety (and why wouldn't it when you wake up because you realize you're not breathing) F 22 1 days

 5  Muscle knots, spasm and stiftness. Marked drowsiness 3-4 hrs. after taking it. Dry mouth. I've found Flexeril superior to Valium for muscle stiffness & pain in back and neck -- believe it or not. However, Valium of course is more powerful on a psychological level. Flexeril mixes well with therapeutic doses of codeine and tramadol. But Flexeril doesn't mix with Valium -- apparently it raises serum levels of Valium substantially, making it feel like you took 2x Valium. Anyhow, Flexeril, despite it's heavy side effects, is the most effective drug I've taken for muscular stiffness and pain. M 49 9 months

 5  Herniation of the C4, C5, C6 Drowsiness. My dosage is 3x daily at 10mg. However, I typically will take just 1 as needed, unless I'm not planning to do something productive, like work the next day, then I will take 2 at most. It's very helpful for the muscles spasms in my neck and back after a car accident. I don't take it daily, just as needed. I haven't experienced any of the other side effects others have noted, just extreme drowsiness which is helpful when trying to get some rest. F 43 3 years

 1  Neck tension headache I'd had a really bad tension headache for about 2 weeks and when I went to urgent care they gave me 10 mg of the generic flexeril. I saw that it may cause drowsiness so I took it at 3 pm when I got home. I slept from 3 to 6 and then again from 8 to 5 the next morning and I still felt messed up like I shouldn't drive to work. It took 24 hours for me to feel functional again after taking the 1 pill. I am a smaller female weighing 110 lbs so things tend to hit me harder but I was not prepared for this. The next couple of days I have had some of the worst anxiety I have ever experienced. After reading other reviews on here I have come to the conclusion they are most likely related. I will not be taking this drug again. F 32 1 days

 3  Chiropractic adjustment went wrong Dry mouth, fogginess, sleepy, trouble concentrating. The worst part was my throat went numb. I told one doctor this and they said it wasn't the drug. Then I read tons of patient reports and the side effects listed by the pharmaceutical companies and there it is. I was told to go to a ENT specialist. That is just more bills. I have stopped taking it and hope that the numbness will go away soon. If it does not then I will have to assume that it is part of my injury. It has been about 36 hours and it still feels like I sprayed my throat with numbing spray. I had bad spasms after my neck locked. This did help to be honest with the spasms, but I think it should only be used for a week or so. I Think after that, it will start to do damage. M 40 30 days

 3  neck and back injury I injured my neck and back in 1990. I have had four neck fusions and one back surgery without a fusion. I have no pain tolerance what so ever. I took Flexerils before surgeries so I could cope with life. After my fusions I tapered back to 20mlg at bedtime so I could wake up after 12 hrs of sleep and make it through the day. I will tell you from my long experience (20 years) on this medicine that it works well to give you a somewhat active life back, but eventually it will weaken your muscles, eliminating support thus creating more pain and will Wreak HAVOC in your body later on in life as you age. I now have TACHYCARDIA (fast heart beats150 to 250 per minute) that I have to control with medication for the rest of my life. It also causes overactive mucus secretions that contribute to bronchial irritations that can lead to COPD (chronic obstructive pulmonary / lung disease) With these two side effects, it makes managing them difficult. The bronchial medicines aggravate the Tachycardia USE WITH GREAT CAUTION SHORT TERM and "DO" READ LOTS OF RESEARCH !! Type in query: "ADVANCED" SIDE EFFECTS OF Whatever Drug you are researching for a fully exposed listing of all side effects with any drug !!!!!! Get all the Facts ! Not just a few !!! Bless us ALL !

 3  Neck spasms Extreme sedation, lethargy, slight slurred speech, disorientation I use only very occasionally for neck spasms. Absolutely cannot use during the day - I would be completely useless. Can sleep 15 hours+ easily, and then wake up feeling drugged and hungover. It's odd because I feel like the side effects get worse every time I use it. I'm not sure of the dosage I'm taking, but I'm going to try to take 1/2 the pill next time I need it. If I still feel like this, I'm going to ask for another medication. Not worth it if you can't function. Took it at 7pm last night -- it's 11 am next day and I feel like a zombie. F 27 5 months

 2  low back spasms Extreme dry mouth. Localized muscle weakness in right triceps muscle and in two fingers on the right hand. Numbness over much of right arm. Have had these side effects for three days and would like to know how long it takes for these symptoms to go away. Took the pills for lower back spasms. They weren't that effective, but did not experience the drowsiness or dizziness that other users reported. Stopped taking the drug as soon as weakness/numbness side effects appeared. Fortunately physical therapy is helping with the back spasms. I would not take it again because of the side effects experienced. I have taken the drug before but never experienced the weakness and numbness until now. M 55 11 days

 4  Muscle spasms / pulled back/spine Slight drowsiness My first time with a hurt back and first time taking this type of medication. I was concerned about some of the low ratings on this website but this medication helped quite a lot. I was able to sleep much better and my back didn't hurt quite as much. Only small feedback...one night I drank 2 beers and almost fell on the floor...I wouldn't imagine even druggies like this sensation. Avoid mixing alcohol and Flexeril. Otherwise an effective med.

 5  fibromyalgia & chronic pain. Miracle drug for me. Accident in '96 completely disabled me. Many Drs & failed scripts later, found that oxycontin, percocet & flexeril gave me my life back. Skip to 2013 & no Dr will treat me severe chronic pain with percs or oxy. Even having problems getting anyone to write me flexeril now. My life is a nightmare of rock hard muscles, tmj, nerve pain & more. Family & friends now send me any flexeril they get so I can sleep, work, drive, be mom & function somewhat normal. I take 20-30mgs b4 bed & 10mgs as needed for muscle stiffness & spasms. Life is unbearable without it. ER treated me like a pill seeker after I fell & blacked out during a time I had ZERO meds & no insurance it dr, when I asked for flexeril to prevent severe spasms. Wtf? I don't get high off my meds, I get a life & work on them. Without them, I'm unable to dress, shower, climb stairs, eat, think, etc. Thank god I have family & friends who give up their meds so I can maintain some semblance of a normal life. Fuck you DEA for taking away our meds so you can shake down Dr Geeks who fold under the threats of losing their licenses so you can stop a small amount of junkies who ruin it for the ones who really need flexeril & oxycodone to function. May you have an accident & get denied pain relief by a Dr you made stop writing pain meds. FIGHT BACK AGAINST THE DEA! I want my scripts back!!! F 42 10 years

 4  Back Pain - Severe Scoliosis Flexeril has been very effective for me. My doctor initially prescribed 10 mg to take at night as needed for back spasms. It works great for getting rid of back spasms - by the next day they are gone! But over time I realized that 10 mg was too much because I felt groggy and irritable the next day. Cut back to 5mg and that works just as well without as much grogginess. As I said, I realized that 10 mg was too much for me, and I am a big person (~225 pounds and 6'1" tall), so I started taking only 5 mg on my own. That works much better for me - still relieves my back spasm, and I am not as groggy or irritable the next day. I do not take flexeril every night - only when I have a spasm. F 47 10 years

 1  muscle spasms Awful, it helped with the back pain but I hated the feeling. First night I felt really out of it and fell asleep for 6 hours, woke up for a brief 30 minutes then back to sleep for 10 hours. I had really strange detailed dreams. I felt really tired when I woke up (coffee didn'tdidn't help) and groggy/hungover all day. As the day went on, I felt extremely dizzy if I stood up to fast and even blacked out.

 1  Sciatica Muscle spasms lower back Couldn't sleep because of sciatic pain so Dr prescribed Flexeril for pain relief and so I could sleep. First night slept for 14 hours. All next day severe sleepiness, hangover type headache, pain behind eye, didn't want to do anything and didn't get dressed until 3pm, total loss of motivation to do anything ! Next few nights, no pain relief at all and worse symptoms of sleepiness, headache and even anger. Will not take this again. I tried it once for TMJ and it took the muscle spasms away. This time for sciatica it is totally useless and caused so many negative symptoms, I will not take it again. Horrible drug F 60 4 days

 1  spasms following neck sprain/strain Dry mouth, tachycardia, hypertension, arrhythmias, extreme sedation, depression. On discontinuation: continued tachycardia/hypertension, vomiting/diarrhea, "hangover" feeling, continued sedation 24 hours after last dose. WelI, I can move my neck again--that's the only good thing I can say. Eased the spasms after 2 doses, but the side effects were intolerable. Pretty sure I was having intermittent A-fib. If I hadn't been so out of it I would've gone straight to the ER. It's a bad scene, when you need help but are too out of it to get it, both from the same drug. It's in the trash now. F 42 3 days
