"I highly recommend drinking large amounts of water with this medication. I was not aware to do so because it was nowhere to be found on the label, and it resulted in vomiting and the runs. After hours of this and speaking with a nurse, I was able to get it under control. Will not ever take again."

"Seriously, the worst! Slightly numbs my tongue but not my throat. I’ve never tried a cough drop that doesn’t work. I thought because it’s a good brand they’d be great. But it’s awful. Now I’m sick and snowed in, so I can’t go to the store and stuck with these horrible cough drops!"

"The packaging for Mucinex is a horrible nightmare. I could not open the bottle. I did the usual push down and turn knob, but it was impossible. My doctor suggested this and other drugs and antibiotics, but I couldn’t get it open - I am so sick that I took a knife to the lid, but it only produced a small slit. So I squeezed the bottle but only got a little out. This is a nightmare, and I will never buy this again. Zero time on medication as I could not get to it."

"Very effective for the sinus congestion and sinus drip. However, continuous use resulted in leg cramps at night. Interfered with sleep. Research says that it can reduce blood flow to legs."

"The side effect was sleeplessness. First night, I was up until 4:00 AM, next night up until 07:00 AM, and again last night I could not sleep. I was taking the Mucinex as prescribed every 12 hours."

"Works okay, but for serious cough problems, get prescription-level medicine. Does help bring up phlegm. Drink lots of water, it will help bring up the mucus faster."
