Mucinex vs. Mucinex DM: Know the Difference
By Shumaila Saeed || Published on February 27, 2024
Mucinex is a medication for chest congestion, using guaifenesin as an expectorant, while Mucinex DM adds dextromethorphan to also suppress cough.
Key Differences
Mucinex is a brand of medication primarily used to relieve chest congestion. It contains guaifenesin, an expectorant that helps loosen mucus in the airways. Mucinex DM, on the other hand, includes both guaifenesin and dextromethorphan, an additional ingredient that acts as a cough suppressant.

While Mucinex works by thinning and loosening mucus to help clear airways, Mucinex DM offers the added benefit of reducing the urge to cough. This makes Mucinex DM particularly useful for treating symptoms of cough as well as congestion.

The primary function of Mucinex is to make coughs more productive by easing the expectoration of phlegm. In contrast, Mucinex DM not only facilitates the removal of mucus but also helps control the cough reflex, providing a dual action in treating cold and flu symptoms.
