About this item
Product details
No one likes to be sick, but Mucinex 12-Hour Maximum Strength Chest Congestion Expectorant Tablets make every sick day a little easier. Mucus is a master of mayhem. It crowds your nose, throat, and makes you miserable.
Does Mucinex Start Working Quickly?
The best chest congestion medicine provides quick, long-lasting relief. When it comes to chest congestion medicine, Mucinex provides great relief. And that relief is just one dose away. Mucinex expectorant tablets get to work fast and last for 12 hours. Mucinex 12-Hour Chest Congestion Expectorant Tablets give you the relief you need whenever the untimely cold comes your way.
What Does Mucinex Relieve?
Mucinex 12-Hour Chest Congestion Expectorant Tablets relieve chest congestion that's caused by excessive mucus. Mucinex works by thinning and loosening mucus. And with extended-release, Bi-Layer™ tablets, you'll have effective relief for up to 12 hours. Chest congestion occurs when the mucus membranes in your airways are pushed into overdrive. Whether it's the common cold or irritants like dust, your mucus membrane becomes inflamed and causes excess mucus buildup in your airways. The buildup of mucus serves as a way to rid your body of your illness or the irritant you breathed in. Mucinex helps dissolve the mucus buildup so you can breathe normally again.
Active Ingredient
Contains Guaifenesin, which is an expectorant that relieves chest congestion and thins & 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.

Brand Name has better packaging
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.
