For Fibromyalgia "As strange as this may sound, I have found that good old Mucinex, that is, active ingredient *guaifenesin,* really helps amazingly with my stiff and achy hip/haunch muscles, tendons, and ligaments. I suffered a very minor injury years ago, but the area around it became stiffer and more painful over time. I noticed once when I had a bad cold and was taking the usual cold remedies that my hip area felt suddenly better. I narrowed it down to the effect of guaifenesin. Since then, I have found that many fibromyalgia sufferers also report an amazingly beneficial effect of guaifenesin on their stiff muscles! It really does work, is sold over-the-counter, and I notice no side effects. They make 600mg tabs, but even 1/2 tab per day really helps me. I hope it helps you too!!"

Mucinex (guaifenesin) for Fibromyalgia "I bought some Mucinex 3 weeks ago for a very bad cough that would not go away. Within a few days, my fibromyalgia seemed to be getting better. Places that always had pretty much the same amount of pain seemed less painful and even the more painful ones were hurting less. The pain has continued to decrease, and I am starting to feel more energetic. This is the best I have felt in years. It was only after doing research online that I found the Mucinex/fibro connection. I only learned that I had fibro last fall, and the prescription drugs have too many bad side effects for me to take them, though I was afraid I would be forced to someday. The Mucinex has had no side effects, and I am feeling better every day."

For Fibromyalgia "I am a 57-year-old male with fibromyalgia. I was diagnosed 22 years ago. I suffered with it for several years prior. Doctors were reluctant to diagnose because it is a difficult diagnosis and rarely affects males. The symptoms were nearly debilitating. Treatment recommended at the time was Elavil and lots of rest. I had some relief from chiropractic, acupuncture, also from B12 and magnesium chloride injections. All relief was quite temporary. After suffering for several years, another doctor started me on the Guai Protocol. He did his research and knew the best results come from true slow-release Guaifenesin only available from a compounding pharmacy. I take 3000 mg per day with few side effects. With Mucinex, relief is far less constant and long-lasting."

For Fibromyalgia "Guaifenesin works to break up the fascia knots in fibromyalgia. It does take a few months to work. Pain is still a major issue, but the knots being gone is a major bonus and helps with the pain factor - a lot!"

Mucinex (guaifenesin) for Bronchitis "I've tried this twice, once for allergy-related coughing and bronchitis. For some reason, for me, this medicine always makes me cough more than I need to. It does thin the phlegm and helps make my coughs productive, but when I need to sleep, this isn't the medicine I can take at night. I use Robitussin DM for nighttime use."

For Fibromyalgia "Many years ago, I was in an FMS support group that filled out forms for Bennett. Not sure if Dr. Armand was around then. During this time, many members of the group did the Guaifenesin protocol as it was just being discussed then. Whenever I had a cold, I took Guaifenesin and felt much better, but when I went off it, Fibromyalgia pains returned. I was diagnosed at the time as a severe, hard-to-treat case. I got into Hormones, which helped immensely. Recently, I've had a bad cold and am taking Guaifenesin again. A lot of very bad pain I’ve had from an injury that affected the muscles, ligaments, and tendons on the right side from neck to knee were alleviated by taking the Guaifenesin. No other reason for it. My cold was awful, but my body pains had subsided. I’m thinking of going on the Guaifenesin Protocol again to see if relief continues. I’ve had FM for 30 years. It has affected every aspect of my life. I will try Guaifenesin again and see what happens. Thank you for your interest."

Mucinex (guaifenesin) for Cough "One of the best things for coughs. The Mucinex DX green does a great job of thinning mucus as well as stopping cough. The blue is good for colds and allergies without cough. I prefer the 600 mg tablets. For me, they wear off after five hours. Take with a lot of water. The more water, the better it works. 16 ozs every 90 minutes makes it work the best."

For Fibromyalgia "Guaifenesin saved my life! I follow Dr St Amand’s protocol precisely, salicylic acid free. I was mostly bedridden, everything hurt from washing my hair to getting dressed. IBS symptoms got so severe that it didn’t matter what I ate, it hurt. As I started the protocol with guaifenesin, my symptoms slowly started to disappear and I started having more good days than bad. It no longer hurts to eat! It no longer hurts to get hugs! I can open jars again! I work 30-50 hours a week and survive without crashing! Every doctor should be prescribing this protocol! Guaifenesin has zero side effects for me, and I am very sensitive to the efficacy of drugs, alcohol, sugar, caffeine, and pain and allergy medications."

For Fibromyalgia "A few years ago I took Mucinex for a cough before going on a hike. I noticed that after the hike, I didn't hurt as much and my recovery time was much shorter. I had bad leg and back pain at the time. A few months ago, I got Q-Tussin for a cough. Wow! For the first time in years, I had the desire to clean the house, and I was able to. I looked up other uses for guaifenesin, and there it was - it helps with fibromyalgia. I have since been diagnosed with fibro, and I try to take the 600 mg of Mucinex twice a day. It may not work for everyone, but it makes me a functioning human being again. I am much happier, in less pain, and my irritable bowel syndrome has cleared up."

For Fibromyalgia "I started a store brand guaifenesin three months ago, 600 mg extended release 2x a day for fibromyalgia. Within two weeks, the extreme muscle cramps in my legs, feet, and torso had decreased by 95%. Now that I have been taking this for three months, my IBS symptoms have decreased. I follow the salicylate protocol, meaning no aspirin or related products, and have changed my toothpaste and facial products to eliminate those that might negate the guaifenesin. I have also eliminated any herbal supplements to give this a try."

For Fibromyalgia "I use 600 mg of guaifenesin twice a day as part of the Guaifenesin Protocol, as outlined in the book 'What Your Doctor May NOT Tell You About Fibromyalgia.' I also avoid topical and dental salicylates (also in the book), and I have begun the process of reversing my fibromyalgia symptoms by expelling the excess phosphates from my system, which contribute to my fibro pain (please read the aforementioned book to get the complete description of the mechanism for this). Guaifenesin is the only thing that has ever worked on my insomnia (suffered for over 40 years of sleep issues), and now I can get good quality sleep! I have had no bad side effects, and guaifenesin has no interaction with other drugs. But I don't need any drugs for pain or fibro!"

Mucinex (guaifenesin) for Cough "At first I thought this was making me worse because of thinning my mucus but I read someone's comment on here who said to drink a lot of water (64 oz) and I tried that and it definitely made a difference. If you don't drink a lot of water with this you are not going to clear out the mucus."

For Fibromyalgia "I tried Mucinex about 6 years ago, but decided it didn't work after only a week of use. About 8 months ago, I started taking Mucinex because I developed a chronic cough (M.D. feels it is due to allergies/sinus drip), and after 3 weeks, I suddenly noticed every cell in my body no longer hurt. Yes, I still have neck and low back pain, but that is unrelated to fibromyalgia. The fibromyalgia pain has decreased by about 75-80% (deep tissue is still sensitive if tested). I take 12 mg Mucinex DM before bed. Both my physician and pharmacist approve. None of the prescribed meds worked and none were without side effects. Sometimes I take a generic, but mostly I stick to Mucinex. I am so grateful to have relief after so many years of suffering."

Mucinex (guaifenesin) "For fibromyalgia: I have been taking two 600 mg tabs per day of the 100% guaifenesin Mucinex since June 2014. Previously was on Lyrica (I now have liver damage I think was caused from that and Cymbalta), which really didn't seem to help much. Can't claim to be totally pain-free because it appears I have a 'weather' body. Whenever a high-pressure storm system comes in, my pain levels go up. I am convinced, however, that guaifenesin therapy works. I have seen other websites that say it is only having a placebo effect, but then how do you explain those people who accidentally helped themselves stop fibro pain when they took it for sinus problems? I now have to be very careful what I take due to liver problems, and guaifenesin has no side effects... So? :)"

For Fibromyalgia "I've had fibro for 15 years. I tried guaifenesin years ago, but not regularly. I was on Lyrica and Cymbalta, but the side effects were awful. I started guaifenesin (Mucinex) again less than a month ago. So far, I feel great. I still have pain, but I can move now. The pain isn't debilitating like it was. It even helped my mood, which has been a huge struggle for me lately. I'm taking 400 mg twice daily for now. I can only have hope. Right?"

Mucinex (guaifenesin) for Bronchitis "I have read multiple Scientific studies of Mucinex comparing it to placebo. Scientists claim there was zero benefit from Mucinex. Drug is expensive and does not have any clinical test results they can point to about it’s efficaciousness. You are much better off inhaling steam, drinking plenty of fluids, sleeping with a humidifier, and using some kind of prescription bronchodilator like Flovent to keep your lungs from getting tight. In severe cases, you should probably try prednisone in the form of pills or try a bronchodilator. Over the counter medication is a poor substitute for seeing your doctor and take the medicine that actually works!"

Mucinex (guaifenesin) for Fibromyalgia "I heard about this treatment from a nurse at the local CVS Pharmacy. I went online and looked up the research done. I've been on it for around 3 months now and it works. I ran out at one point and didn't think much of it, and my pain came back. I suggest you try it; it really does help. I use it along with Pure Malic Acid, and the two things together gave me my life back."

Mucinex (guaifenesin) for Fibromyalgia "I had severe tendinitis after 5 rounds of high dose chemo, probably as a side effect of the antibiotic Levaquin. I had my RA factor checked to be sure rheumatoid arthritis hadn't kicked in with the chemo and it was normal. But I was in serious pain. Then I got a cold last week and picked up some Mucinex for the cough. Amazingly, the tendinitis has settled way down. I only took Mucinex for 3 days and now, a week later, I am still enjoying the benefit. I am not 100% pain free, but probably 90%."

For Fibromyalgia "My right foot has been extremely painful for the last 10 years. I realized there were days when I limped quite a bit. Friends started telling me, even on days when I thought I was walking normally, 'I didn't know you were limping.' I blame my foot pain on playing racquetball for 20 years. Finally had to quit. Recently, I had a cold that is now just clearing up. I began taking 400 mg of guaifenesin yesterday. I took one during the day and one at bedtime. This morning, I stopped at the grocery. When I got out of the car, I immediately noticed that the pain in my foot was gone. I remember saying to myself, as I walked into the grocery store, 'What is this with my foot? It feels like it did over 10 years ago.' I was able to run on it. Amazing!"

For Bronchitis "I have COPD and have been using guaifenesin for several years. It works wonders for coughs, I think the liquid soothes your throat better. BUT IT IS IMPORTANT NOT to get the 'DM' or any version of it with dextromethorphan in it. Those of you having dream disturbances or nervous reactions are surely using this. You want to buy the plain 'TUSSIN' that is only an expectorant and nothing else. Also, drink plenty of fluids to help liquidize the mucus. I will swear by this stuff, but you have to read the labels and be careful what you buy."

For Fibromyalgia "I had been a healthy, active male with no previous health issues. In 2000, I experienced a very minor injury, which all on its own progressed until all of my muscles, tendons, and deep tissues were wracked with pain...10/10. I could not sleep for more than a few hours, and I could not stay awake for more than a few hours. My life was destroyed. After prolonged testing, I was diagnosed with fibromyalgia. Amitriptyline only masked the pain, but I've had to increase the dosage over the years, and the fogginess in my head was terrible. A month ago, I tried Mucinex 2x/day, and the pain and fatigue and fog have since evaporated! I can run long distances again!!! No pain; no fatigue. I feel like Rip Van Winkle...where did the last 16 years go?"
