Never run out!

When I run out of my Mucinex, my sinuses start bothering me with drainage, scratchy throat, sinus pressure. With my other meds, it helps keep me clear.

I like Mucinex because it stops my sinuses draining down my throat. Before I discovered Mucinex, my sinus drainage problem usually resulted in bronchitis.

works great

I like the fact it is two colored so I can identify it from other pills for I have to take it four times a day because I had lung cancer and do not have all of my lungs and Mucinex keeps my lungs cleared of excess mucus and helps me breath better with oxygen
