This stuff works wonders for my husband who has serious sinus pressure issues and is prone to sinus infections. He had previously been using a similar product for sinus pressure and pain, but it didn't work nearly as well as this product. Guaifenesin for the win!

Great

Better than the rest!

This product works. I like being able to get from Sam’s in a large package.

We use mucinex forallergy or colds in winter. Good product and we re-order several times. Good deal on price.

Its that time of the year! The yellow hazard is everywhere. Pollen which is the only gateway to beautiful flowers. I can survive now with this Mucinex product. It works fast, long, and no drowsiness.

My doctor recommended that I take Mucinex every day to help control congestion, as I have major lung/breathing issues. Mucinex helps keep my sinuses clear.

Allergies impact chest congestion but the 12 hours pills keeps congestion out of lungs and bronchial areas. Keeps me breathing better even as pollen and other allergens at worse

The Member's Mark brand worked just as well but I can't seem to find it any more. That's the only reason I didn't give it five stars (because it's not as inexpensive as the generic).

I swear by Mucinex for taking with the onset of a cold because it helps me with not being so stuffed up and it keeps it from ending up in my chest. I keep this in my house for colds.
