For Fibromyalgia "Guaifenesin really does work. I'm a 26 year old female recently diagnosed with Fibromyalgia. I have been to several doctors within the past several months because of the pain that Fibromyalgia has caused. Out of all the potentially harmful meds I've been prescribed, this is the only medication that has actually helped and to this day continues to help. I have used Mucinex for over a month without any side effects. It has also helped with Irritable Bowel Syndrome, acid reflux. I would highly recommend this to anyone suffering from a terrible disease such as Fibromyalgia."

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 "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!"

For Fibromyalgia "Many yrs 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 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 a bad cold and taking Guaifenesin again. A lot of very bad pain I’ve had from an injury that affected the muscles, ligaments, tendons on 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 Guaifenesin Protocol again to see if relief continues. I’ve had FM for 30 yrs. Has affected every aspect of my life. Will try Guaifenesin again and see what happens. Thank you for your interest."

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 where 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 on-line 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 everyday."

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, Drs 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. Had some relief from Chiropractic, acupuncture, also from b12 and magnesium chloride injections. All relief was quite temporary.After suffering for several years, another Dr 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 RX. I take 3000 mg per day with few side effects. With Mucinex, relif ia far less constant & long lasting."

Mucinex (guaifenesin) for Cough "One of the best thing 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 tables. For me, they wear off after five hours. Take with a lot of water. The more water the better it works. 16ozs every 90 minutes makes it work the best."

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 "I started a store brand guaifenisin three months ago 600mg extended release 2x a day for the 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 guaifenisin. Have also eliminated any herbal supplements to give this a try."

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."

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 use 600mg 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!"

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 12mg Mucinex DM before bed. Both my physician and pharmacist approve. None of the prescribed meds worked and none were without side effect. 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 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!"

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 are 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 help my mood, which has been a huge struggle for me lately. Im taking 400mg twice daily for now. I can only have hope. Right????"

Mucinex (guaifenesin) "For Fibromyalgia: I have been taking two 600 mg tabs per day of the 100% guafenesin 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 guafenesin 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 guaf has no side effects... So? :)"

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 which 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!"

Mucinex (guaifenesin) for Fibromyalgia "I heard about this treatment from a nurse at the local CVS Pharamacy. 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 Bronchitis "I have COPD and have been using guaifenesin for several years. It works wonders and 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. "

Mucinex (guaifenesin) for Bronchitis "Mucinex works great for colds and to help get the nasty stuff up before it takes root in the lungs, but for Bronchitis you will definitely need something much stronger (see a doctor) unless you want to be sick for about 4 weeks."

Mucinex (guaifenesin) for Bronchitis "Have been taking 1200 mg slow release Mucinex (plain guaifenesin) for two weeks and it has helped loosen mucus in my lungs. It does require drinking LOTS of water to be effective. In my case 64 ounces a day. Noticeable difference in breathing and timbre of my voice. All that said, hoping I can stop taking the medicine and simply work on staying hydrated."

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. Amitryptaline 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 distance again!!! No pain; no fatigue. I feel like Rip VanWinkle...where did the last 16 years go?"

For Fibromyalgia "My regular meds from my Rheumatologist stopped working and I could barely get out of bed or even hold a glass of water. I found out about the use of guaifenesin and started the protocol. It’s not easy, as you have to be so careful about what you eat and put on your skin, so I wouldn’t recommend it unless you’ve tried other options first. The Guaifenesin absolutely worked for my fibromyalgia and all my pain has subsided as well as my fatigue. It was well worth it! Make sure you read up on the protocol first though and follow it exactly or it won’t work."
