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!

I am happy with the product, but I was cheated out of the “Instant Savings” price when I purchased the Mucinrx. I met all requirements to receive the discount, but I was charged full price. I have not been able to get the $6+ returned to me. I expect better from Sam’s Club.

Excellent

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

These work great for removing mucous. I've tried the MM brand (that are better price) but the MM pills are huge %26 hard to swallow.

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

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

I have used Mucinex for years. When I need congestion, I turn to Mucinex for 2 reasons. Mucinex is effective at eliminating congestion and is affordable when purchased at SamsClub.

This stuff really works - an hour after I took it I sneezed and it was almost like a demon was being chased exorcised out of my nose. I’ve never been so clear

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.
