Mucinex Works!
Mucinex works. I had a cold and needed to go out but was coughing and had sinus problems constantly blowing my nose, drainage. This reduced all of that quite a bit for at least 10-11 hours.

Performs great but the size of pill is not great
I use this all the time when I get sick. Works great. The only problem is the Thanksgiving Day turkey-sized pills. Why are we still making these archaic monstrosities when there are liqui-gels and other options out there? They need to develop a much easier delivery method than this.

Works just like the packages says.
This truly worked for me. Had flu like symptoms, mainly painful cough and bronchial congestion. Literally within minutes it started easing up and continued feeling better for hours.

Works well but too BIG
Good product and works well but as Horrific stated, IT'S TOO BIG! My husband is 84 and has great difficulty swelling your monster pill. Why can't it be made two pills like many other needing to be large doses in pill form separated into two?

Side Effects
Works WELL . HOWEVER. I always have a nasty side effect of sulfur smelling urine. So much so, that I won't take this medicine if I know I'm going to be around people.

Not worth it
For the cost, it should have worked much better

Does Not Work
Took two tablets with water. Did not work at all to alleviate coughing. Mucinex used to always work for coughing fits. I don’t know if they changed the formula or if the batch that this box of Mucinex came from is a knock off.
