For Expectoration: “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!”

For Expectoration: “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.”

For Cough: “Medicine works very well for the specified 12 hours but wow it is very strong. I weigh 105 pounds and taking an entire pill will have me falling over and seeing double very shakey also but giving it a seven because at least I can breathe now and this is the only medication that works for that my inhaler won't even help me any more.”

For Expectoration: “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.”

For Cough: “I had flu symptoms after a flu shot. They came on immediately but the pharmacist at Walgreens said that the connection was impossible and recommended Mucinex. It does absolutely nothing to relieve the cough, runny nose or anything. She said that the Nyquil I intended to buy wouldn't work. No more Walgeens or Mucinex for me.”
