Mucinex D has guaifenesin and pseudoephedrine.
Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
Mucinex DM contains guaifenesin and dextromethorphan.
Dextromethorphan is a cough suppressant. It affects the signals in the brain that trigger cough reflex.
