Mucinex and Mucinex DM are both cough and cold medicines, they act as expecto-rants. An expectorant is a medicine which helps to thin and clear the mucus or phlegm that blocks the chest and nasal tract during a cough or flu infection. Being that they both serve the same purpose of thinning and clearing mucus, the two med-icines are only slightly different in terms of their efficacy and other parameters . Here are some differences between Mucinex and Mucinex DM.

Mucinex is mainly made up of an expectorant component known as guaifenesin while Mucinex DM contains both guaifenesin and another component known as dextromethorphan HBr. Dextromethorphan HBr helps in suppressing cough.

Efficacy and strength
In terms of efficacy, Mucinex DM works more effectively to relieve coughs and colds than Mucinex. Mucinex clears chest congestion but Mucinex DM eases out mucus better than it. Mucinex DM is also capable of clearing sinus infections apart from colds and coughs. Mucinex DM is more effective in relieving coughs than Mucinex because it contains dextromethorphan HBr which is a cough suppresant. Mucinex DM can clear both dry and wet cough. People with mild cough should try Mucinex first and only opt for Mucinex DM if the cough is persistent.

Mechanism of clearing coughs and colds
Mucinex and Mucinex DM work in different ways to clear mucus which forms in the nasal cavities during coughs and colds. Mucinex works by thinning and loosening mucus. It’s believed that Mucinex irritates the gastric mucosa and thereby stimulates the secretion of respiratory fluids. Increase in the volume of respiratory fluids con-sequently leads to mucus becoming less viscous. The less viscous mucus can then be easily swept away and the nasal passages cleared.
