A dry cough is 'unproductive', that is not accompanied by mucus or phlegm.
Sometimes, a dry irritating cough may be accompanied with occasional phlegm. The constant coughing can dry the air passage and making the small amount of phlegm hard to move.
Robitussin DM provides symptomatic relief for congested chests and coughs.
Robitussin DM contains a cough suppressant, Dextromethorphan, which helps to reduce the amount of annoying coughs. An expectorant, Guaiphenesin, is also present in Robitussin DM, to help loosen phlegm and thin bronchial secretions, which helps to make cough more productive.
