Mucinex helps dissolve the mucus buildup so you can breathe normally again.</p> <h3>Active Ingredient</h3> <p>Contains Guaifenesin, which is an expectorant that relieves chest congestion and thins &amp; loosens mucus, making coughs more productive. Guaifenesin (1200 mg) is an expectorant that helps reduce chest congestion caused by colds, infections, or allergies. It works by thinning the mucus in the air passages and makes it easier to cough up.</p> <h3>Stock Up Now</h3> <p>Stock up on Mucinex now. Future you will be very glad you did.

I prefer the Members Mark generic for its lesser price but can’t punch the tablets from out of the blister pack with the rheumatoid arthritis in my hands. Pay a higher price for the brand name to get easier to use blister packs. Wish they were still loose tablets in a bottle.

Brand Name has better packaging

Stopped my cough by loosing the mucous.  I take it whenever I get stuffed up or the wheezing starts.  Works so well and I depend on it to bring me thru this flu season.

Works

This is the only product that actually works. I take 2 a day AM & PM for 2 wks.

Sinus season remedy

Good stuff, but more expensive than the Members Mark generic. Mucinex indicates a two phase effect but I haven't really noticed a difference.

Full strength but is it worth the extra cost

Cold remedy

Works perfectly with great instructions. Highly recommended for congestion.

Fantastic Product!

Great product

Best on the shelf for loosening up mucus in your lungs. 
I have one working lung and disabled for the rest of my life, I have to worry about fluid build up in my lung. All my doctors recommend Mucinex to help me breathe healthy and stay healthy.
When I get pneumonia and have to go to the hospital, Musinex is what the doctors prescribe to help me get healthy along with restricted prescriptions.
Thank you Mucinex for helping me breathe better!

Best on the shelf…

I had ordered the wrong one on this so I took it back to store and ordered the right one but we take this every night before bed and it keeps us from coughing so much at night

walmart.com

I never received order and tried at least 3 times, management was to get in contact with me but I still have not heard back from anyone.  Was in contact with Sam’s club at least 3 times.  Not sure if it’s a production issue with employees needing to get numbers or what…..
