Mucinex is the brand name of an expectorant called guaifenesin that relieves chest congestion caused by colds, infections or allergies, according to Everyday Health. It loosens phlegm and thins bronchial secretions to rid the bronchial passageways of mucus, states Mucinex. It also makes coughs more productive. Guaifenesin is combined with other medications to provide relief beyond thinning mucus in the air passages and making productive coughs.Continue Reading
One combination is Mucinex D, notes Drugs.com. This medication combines guaifenesin with pseudoephedrine hydrochloride, which is a nasal decongestant. While loosening mucus in the throat and lungs, Mucinex D relieves nasal congestion caused by the common cold, hay fever and upper respiratory allergies. It promotes nasal and sinus drainage, which relieves sinus congestion and pressure and opens nasal passageways to allow freer breathing.
Another formulation is Mucinex DM, which contains guaifenesin and dextromethorphan hydrobromide, explains Drugs.com. Dextromethorphan hydrobromide is a cough suppressant. In addition to relieving chest congestion, Mucinex DM stops coughs that are caused by minor throat and bronchial irritation that occur with colds and inhaling irritants. It diminishes the intensity of coughs and controls the urge to cough while sleeping.
Mucinex, MucinexD and MucinexDM are available in regular and maximum strength doses. They are available with a doctor’s prescription and over-the-counter, reports Everyday Health.Learn more about Cold & Flu
