"I wasn't feeling well and it was recommended that I try Musinex DM. I took one 12hr pill and started to feel better or so I thought. Half through the 12hr dose I started to have blurry vision and I could feel something covering my eye. I went to look at my eye and I had green mucus coming out of it. First it was one eye, then it was both. I thought I might have conjunctivitis (pink eye) but once I stopped taking the Musinex DM the issue went away. I will never again take this product. Just doesn't work for everyone."

"215 lb. male with headcold / chestcold and extreme congestion. Only used Mucinex for two days during daytime with lots of H2O. Broke all congestion loose resulting in sinus drainage and productive cough. Great stuff. Made me feel kind of "buzzy". I would not recommend mixing with other meds (e.g., Nyquil). This would likely cause adverse reactions. Very important to over hydrate when taking!"

"This medication combines both Dextromethorphan (suppression) and Guaifenenesin (thins mucus). As a result, the ingredients work against one another to a certain extent. Those using it and experiencing adverse effects (dizziness, racing heart rate, panic, etc.) were likely reacting to the Dextro, which triggers many of the issues that are being complained about. So my suggestion is to use Mucinex (plain basic type) first thing in the morning. It lasts for 12 hours and allows your chest to cough up the mucus and clear your lungs. Then at night, use a cough suppressant (not including Guaifenesin) medication that will allow you to sleep and bring the other benefits you seek. Do not blame a product when you have not done your homework! You should consult with the pharmacist if you have any health issues or are likely to experience any drug interactions. Also, do not take the maximum dose unless you discover you need it. Remember dosage levels relate to body weight too!"

"While taking Mucinex DM 600mg, twice a day for 7 days, I hadn't realized why I was itching something fierce. Until my 7th day when I looked up the side effects. Absolutely nothing helped to ease the itch all over but scratching. Other than that, my congestion has eased significantly."
