Guaifenesin "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, it's a great medication but eat something before taking it."

Guaifenesin "This medicine really helped me out with a bronchitis attack. I have been suffering from 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!"

Guaifenesin "It works well, 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 at night. I took the pill, not liquid. I have to say I was surprised."

Guaifenesin "I’m a second-grade teacher and have had an exhausting case of bronchitis for four months now. Many of those lovable 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 the doctor 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 yuck is finally getting out of there!"

Guaifenesin "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 they may have taken the one with pseudoephedrine 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 mucus is expelled much easier, and then it's over. Then it's time for another pill. I highly recommend this product for coughs."

Guaifenesin "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."

Guaifenesin "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 breathe deeper and easier!!"

Guaifenesin "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."

Guaifenesin "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."

Guaifenesin "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 withdrawals and later take care of the physical withdrawals, not both at the same time."

Guaifenesin "I have used it twice now. And it feels like it makes me worse. I cough so hard that my back and my stomach are now hurting. My cough is so deep, and nothing is coming up. It just makes me cough non-stop. 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."

Guaifenesin "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 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."

Guaifenesin "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."

Guaifenesin "Mucinex works great for colds and helps 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."

Guaifenesin "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 '80s, 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."

Guaifenesin "Took this medication for a chest cough before I went to bed. Woke up in the night with severe nausea and felt dizzy. Tried it again a week later and the same happened. I know other people who swear by it."

Guaifenesin "In our home, Mucinex is the go-to when we start getting sinus-y, mucousy, and sickly. It helps fast, glad these products are available! We use the liquid for our 9-year-old, and it usually always works! Thank you, Mrs. Perez."

Guaifenesin "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 anything 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 doctor if this sounds like you - it turned out I had community-acquired pneumonia."

"Guaifenesin is great for my bronchitis. But, I have learned that whether I take the liquid or tablet, I must eat first. If I take this on an empty stomach, which is what I did about an hour ago, I have such a reaction it almost puts me on my knees. Luckily, within 15 minutes of realizing what was going on, I was able to get something to eat. The first reaction was almost 20 years ago with the liquid, I ended up in the ER. I didn't know what was wrong. Today I took a pill on an empty stomach, and my stomach began to cramp severely within a short time. This was a sinus/mucous relief tablet with guaifenesin. I'm okay now, but do not take guaifenesin on an empty stomach! You don't want to try it first. I'll keep taking it, but eating first."

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

Guaifenesin "I'm not sure Mucinex works. I know it kept me wide awake. It was hard for me to sleep. When I was awake, I felt like my balance was off, so I felt dizzy. I couldn't go down spiral steps. I would not recommend it."

Guaifenesin "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!"

Guaifenesin "Have your local compounding pharmacy order you the pure guaifenesin syrup. You do not want the kind in the drugstore because it contains dextromethorphan ... which is probably what others have described as making them sick or drowsy. The brand my pharmacy gets for me is Robafen syrup. You can get a pint for about $8. I have COPD and have used it for years. Robitussin used to make the plain stuff, but I haven't seen it in the stores for a long time. Although it says only take 6 times daily. It's much more soothing to the throat than Mucinex pills and works instantly to get the phlegm out of your lungs. I couldn't live without it!"

Guaifenesin "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."
