Mucinex (guaifenesin) "I can't take any form of Mucinex, or it's generics, without becoming totally lethargic. I turn into a complete zombie. I'm happy for those of you who find relief with it, but for me, it's a total fail."

"I have osteoarthritis of the spine and have severe muscle aches and pains all day long and worse at night. I find that when I take 10ml of robutussin chest cough mixtureIi am pain free for the day. Another 10ml guarantees a good night sleep. Though not confirmed I suspect I have fibromyalgia...in addition to the osteoarthritis."

"I agree it probably doesn't work for the reasons set forth by St.Amand, but it did work for me (complying with the salicylate ban) in the timescales he finds, as follows: 3 days of nothing Then 2.5 days of feeling great Then 7 months of feeling worse than ever Then roughly 2 years of feeling much much better, but eventually it tailed off to nothing. Still the only effective FMS/CFS medicine I've tried except for LDN."

"Today my doctor told me to try Guaifenesin for fibromyalgia. I'm thankful for all the reviews offered here especially the one saying to purchase the single ingredient product to be safe. I get a lot of side effects. I purchased the store brand Tussin which only has Guaifenesin as the active ingredient. I'm starting today and I'm very optimistic about improvement. I will post another review as soon as I can see the benefits."

"I'll call it "guf" for short. Guf works but you have to understand your body. For a cough it helps by enabling free-er breathing, loosens, disolves flem. "Guf" used for treating fibromyalgia has done wonderfully for me, but you MUST ADHERE to a strict diet for AT LEAST ten days while dosing, I felt good results in a few days and it gave me the inccentive to keep doing it for 14 days, I felt so good, the diet is described in a small green book called "what your doctor didn't tell you about fibro."

"Was "mapped" by Dr. R. Paul St. Amand and Dr. Melissa Congdon. Their maps were a little different but both of them diagnosed me as having fibromyalgia. Began the guaifenesin protocol about a year ago. The first capsule worked a little the very first time. That was it. Nothing has improved since then. I still have the same exact problems I've had for years. All I can say is I'm glad I'm not in as much pain as some others on this message board. Was advised to take more which is strange to me because I consume 800mg twice per day."

"I never thought that an expectorant used to treat coughs could be this effective for Fibromyalgia pain. I am a pre-med student and when I heard about the possibility of Mucinex(Guaifenesin) being able to relieve pain caused by Fibromyalgia I decided to try it. It has worked better than NSAID'S (Ibuprofen, Aleve, Celebrex) for me. 400mg works great (600mg if using the extended release tablets.)"

"Good evening While watching a mystery show on the ID channel, the story was about a lady with Fibro, and she was taking Guaifenesin, and I thought, what? Never heard of that. So, here I am, reading up on it. I have fibromyalgia, and multiple sclerosis. The fibromyalgia symptoms are way worse than the MS. So, any advice, or what kind I should buy, where, dosage, etc. I’m excited to try the Guaifenesin! Thanks."

"After discovering the guaifenesin protocol for fibromyalgia 6 years ago, I have been able to reverse 90% of my symptoms. My case had been very severe, and I was giving up on life. I was 49 then and doctors were out of ideas, and told me I had the body of a 95 year old. After a dozen or more bone spur and related surgeries (and still no FM diagnosis) I researched what these accumulated deposits were made of (calcium phosphate) and sent away for a simple hair analysis test. The hair test was telling.Extremely high phosphate and calcium. After research I stumbled on the guaifenesin protocol by Dr. St. Amand, and everything suddenly made sense. The theory is centered on phosphate retention. That day I diagnosed myself with FM and have never looked back, improving daily since. The protocol can cause deep discomfort if too much guaifenesin is taken, (I only need 150mgLA/day) and you need to cycle all your old symptoms again in reverse to get "clear", but it really works and saved my life."

"When I was first diagnosed with fibromyalgia this was the first drug I was started on and what a miracle. Then it was taken off the market to go onto the OTC side of the store (Over the counter). Over the years I would get a cold and every time my pain disappeared I was happy no pain but a stubborn nose drip. Over the past 10 years I could not wait till I got a cold now I am gonna try the guaifenesin protocol even I do remember it was a higher dosage than normal this will probably be expensive but it is worth it."

"Okay so hear me out. I found this by mistake and after reading reviews I can see Mucinex has helped others with Fibromaylagia. There is no way it's a placebo. Let me start by saying I've been sick with cold viruses before and have taken the 400mg doses of mucinex and never saw a difference in pain.. This is the first time I went and picked up the 600mg extended release to take twice a day vs the 400mg twice a day for my chest congestion and there is a difference. It isn't drastic to where all my pain is gone but I do have other health and spine conditions but enough to where I knew something was very different and didn't know what. I figured maybe because I was sick that my body was in a more relaxed state so my pain was down but I never felt this way before ever. I plan on trying 800-1200 twice a a day but so far I'm extremely impressed even with the 600mg extended release twice a day. I've only been taking for 3 days and waking up without morning stiffness is huge!"

"I have been suffering with fibromyalgia for many years. Guaifensen 2400mg to 4800 mg a day loosens my muscles that are tight and painful. I'm able to breathe deeper with the relaxed muscles. My stomach isn't as irritated, and skin isn't as irritated. My anxiety is lessened. I've also included Ribose powder 10 to 15 mg a day and it helps with fatigue."

"All the other meds I've tried have made me miserable or brain fog so bad I could barely function. Even CBD didn't do as good of a job as this did. It's not 100% gone, but it's significantly better than it was to where I can function and not be distracted by the pain."

Mucinex (guaifenesin) "I was desperate with severe, throbbing pain, especially at night. I was actually envisioning suicide. In suggesting Mucinex to a friend, I happened to discover that guaifenesin has a moderate muscle-relaxing effect, and then I read some of these reviews. I also read a report of a clinical study that found no effect. Long story short, the women in the clinical study took only 600 mg twice daily, whereas most of the reviewers here seemed to have taken twice that amount. I started doing that too, only yesterday, and today my spasms are largely gone. My conclusion, therefore, is that the clinical study didn't use a large enough dosage."

"I have mild fibromyalgia and migraines. Since taking guaifenesin 1200 mg twice daily, it’s been a huge improvement. After the 3 rd or 4 th day migraines are gone! I have been doing it for 2.5 weeks now. If I am 4 or 5 hours late on the dose : a migraine comes. But if I take it consistently, I am migraine free! Simply Amazing!"

"I looked up guaifenesin to see if it actually works as an expectorant (thinking maybe the glass of water you're supposed to drink with it does most of the work), and I read some people take it off-label for fibromyalgia. It didn't seem like there was much evidence for it, and the mechanism given was vague and didn't make much sense, but other people seemed to think it helped. I also read it doesn't really interact with other meds or have much in the way of side effects, so I figured it wouldn't hurt anything to try. I took 1200 mg once a day for a few weeks. My pain varies, so it's hard to tell if it really did anything. I did feel like I noticed an increase in good days, but it wasn't obvious enough that I could say for sure. If it did help, it's possible that adding a glass of water to my day is what made the difference. I didn't really notice any change when I stopped taking it, which suggests it probably wasn't doing much. It did seem to help with mucus though."
