"Mucinex is great and it works well but whatever you do, DO NOT take it on an empty stomach. I did this morning and as the day went by I kept feeling worse and worse. When I finally got the chance to eat something, my stomach was so upset that it just came right back up. Again, its a great medication but eat something before taking it."

"This medicine really helped me out with a bronchitis attack. I have been suffering with acute bronchitis for about 3 weeks now, after taking all of the medication that my doctor prescribed I still have no relief. After reading reviews I decided to give Mucinex (liquid) a try, to my surprise it really helps to bring up all of that sticky mucus that was stuck in my lungs. Although I'm not fully well yet, I can see better days ahead!"

"It works good, you will feel the congestion breaking down. It does make you cough more to loosen up mucus and yes you probably will stay up a bit a night. I took the pill not liquid. Have to say I was surprised."

"I’m a second-grade teacher and have had an exhausting case of bronchitis for four months now. Many of those loveable little petri dishes I teach have been sick too. This week I’m much worse with very painful throat and ear pain and congestion. Went to dr. yesterday feeling like I’ll do anything to get better! So amoxicillin for ear and throat, two shots of I don’t know what in the backside, Mucinex for the thick nasty phlegm, and Flonase, Claritin, and Zyrtec to alternate. Best thing—- the cough is finally actually bringing the stuff up about 6 hours after taking a 12-hour Mucinex. And lots draining out the nose too. I’ve never tried it before but it’s sure working. All that yuk is finally getting out of there!"

"I took Mucinex for a bad case of bronchitis. It worked very well and I was finally able to stop coughing and start breathing again. The only problem was that it interfered with my sleep. I was awake most of the night and was not tired the next day. I had to quit taking it."

"My dry cough turned into a wet (mucous) cough, later diagnosed as bronchitis. I was getting very little sleep, and then saw a commercial about Mucinex DM for coughs which is the guaifenesin and Dextromethorphan. I tried it, one tablet every 12 hours. In that first 12 hours, I got relief enabling me to finally sleep well all night. I had no problem with it affecting my sleep like some others experienced in these reviews, but hey may have taken the one with pseudoephridrine which keeps you awake. What I have noticed is that the cough is suppressed until you get close to the 12-hour period, then the cough begins. But it's productive, and mucous is expelled much easier, and then it's over. Then it's time for another pill. I highly recommend this product for coughs."

"I get asthma “colds” that turn into Bronchitis once a year. I find Mucinex “keeps the elephant off my chest”. And, you’ll know what that means if you’ve had bronchitis! I will take Mucinex in the morning, and feel fine most of the day, thinking I’m getting past the infection. Then WHAM! Elephant...on...chest!! Cough, cough.... Mucinex may not work for everyone, but it sure helps me breath deeper and easier!!"

"I have used it twice now. And it feels like it makes me worse. I cough so hard that my back and my stomach is now hurting. My cough is so deep and nothing is coming up. It just makes me cough non-atop. However I'm not taking any today I'm also not coughing so I put the two together when you take it it makes you cough unfortunately in my case nothing came up"

"Made coughing a lot easier after feeling like I was going to die from the phlegm that was blocking my air passage. I didn't give it a full 10 because it gave me a slight headache and a bit numb/tingling feeling all over my body but nothing to be alarmed about. Oh my goodness what a difference. I can breathe and finally sleep knowing I'm not going to choke to death. Thank you Mucinex."

"Mucinex worked like a charm for me. When it ran out, I made the mistake of waiting a few days before I went out and got some more!!! Since I have Chronic Bronchitis, I will always have this medicine on hand. I had to see a doctor before taking it, since I am taking other medications, and had to make sure there would not be any dangerous interactions. This medicine is a wonder drug for me. I have now quit smoking, and am using nicotine gum. If your Bronchitis is caused by smoking, you also need to quit. The nicotine gum will keep your nerves calm, and that way you won't have to quit cold turkey. When on the gum, you can take care of the psychological withdrawls, and later take care of the physical withdrawls. Not both at same time."

"First time Mucinex DM user. I like the extended relief because it really does provide extended relief from the severe coughing that is characteristic of bronchial infections. The medication did make me a little drowsy, so some caution is recommended especially if you are not able to take time off to rest. I also recommend drinking lots of fluid too. You may notice that your urine smells like the medication."

"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."

"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 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."

"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."

"I read many reviews some positive and some negative. But people need to remember it will work for some and others it won't. In the 80's my allergist prescribed "Guaifenesin" for me. It really was the best for me. Then it was taken off the market for a while. Several months I was looking for something to help me with my congestion and allergies. Found Mucinex and have been using it as needed and I feel great."

"I have Moderate COPD. Got some kind of Crud (I call it) in my chest and was coughing and so sick. Couldn't cough up any thing but knew it was there. Took regular Mucinex generic label. Felt like I was drowning. Post nasal drip putting fluid in my lungs and I was drowning. Please go to the Dr. if this sounds like you - it turned out I had Community Acquired Pneumonia."

"I began a cough 4 weeks ago. Then the mucus started. Couldn't get it up. Pharmacy suggested Robitussin which worked ok, but still needed stronger meds. Dr. Put me on steriods and antibiotics. Still mucus choking me. Tried Musinex 600. Nothing. Made me worse. The coughing started and was horrible for about an hour. I stopped using Mucinex went back to Robitussin. This drug is not for everyone. Would not recommend."

"Although Mucinex contains the exact same drugs as Robitussin D it doesn't work nearly as well for me as Robitussin D. Maybe because the Robitussin is a liquid? Mucinex has spent a lot more money on advertising but I would choose Robitussin D every time!"

"After struggling for 3 nights with excessive phlegm and trying literally everything (Expectorants etc...) to loosen up mucus, nothing made me have the real improvement that I needed, until I took the first Mucinex tablet and in the hour improvement did occur to my total surprise how effective it was... I am an anti-medicine guy but the situation was suffocating... I just feel sorry for all people who don't know this medicine that is why I write, so that someone will improve as I did... I rate it at 9 because no medicine can be 10 due to possible side effects, BUT NO SIDE EFFECTS FELT FOR ME AFTER 48 HOURS OF USE."

"Jayce Wyatt My chronic bronchitis started out with post-nasal drip and a cough and I felt tired and turned in early. The next day the cough got worse and I felt lousy, so I called in sick. I felt steadily worse for another day, then on day three the fever started, and I couldn't sleep for more than an hour or so at a time for a whole week. When I went to the doctor I was given a Z-Pak, albuterol inhaler (the only thing that did me any good), oral steroids, cough pearls which didn't do any good, and was told to take Mucinex. In all, the fever lasted six days. I coughed so much I hurt my back and ended up in the emergency room because my back went into such spasms I couldn't move without extreme pain. They shot me full of morphine."

"I'm reading a lot of reports of Mucinex making people feel worse, as is the case with me. The main ingredient apparently thins down your mucus so basically, while already sick, this medicine gives you a runny nose. I've taken Mucinez twice and both same results."

"I’ve been using Mucinex to thin and loosen mucus for YEARS now. The one that’s pseudoephedrine and guaifenesin is for sinus congestion, and the other one is for chest congestion. Pseudoephedrine WILL keep you awake and that’s the one people use that drug to make illegal substances; primarily why you have to go to the pharmacy counter to get it. Guaifenesin is highly effective for loosening mucus and excreting it through nose blowing or coughing. I’ve never had issues with either version or Mucinex when taking them during a sinus infection or bronchitis infection. For a bacterial infection you’re going to need antibiotics as well, or the bacterial infection will just fester. Like Shrek says “Better out than in, I always say”. A person’s reaction to meds always differs from another’s experience, but I’ve never had a bad one."
