For Bronchitis "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."

For Cough "I had a runny nose, blocked ears, headache, and sore throat with mucus. It's great! I took one pill and saw relief, so 4 hours later I took the second one. Now I am wide awake. It's almost 4 am. Take it earlier."

"When I first started using Mucinex, an oval-shaped pill, about seven years ago for cough congestion, they worked great. As the years progressed, whenever I had similar symptoms, Mucinex worked less and less. I switched to the liquid formula about three years ago with the same results. I am on day three of using Mucinex congestion and cough medicine. I will never take this medicine again because I feel a lot worse after starting it. I can't sleep because of excessive coughing that I didn't originally have, headache, which I rarely get, and nausea. Not worth it. I'll try home remedies the next time."

For Bronchitis "I had tried this product in 2005, and it was not effective. So I gave it another chance to so-called redeem itself. Well, this is definitely not for me, it made me feel worse. I developed a headache."
