Robitussin PS

Chest Coughs and Nasal Congestion

Robitussin PS provides symptomatic relief from congested chests and coughs as well as nasal stuffiness due to the common cold.

Robitussin PS contains the expectorant Guaiphenesin which increases the flow of natural secretions along the lower respiratory tract. This liquefying effect helps break up a cough - helps loosen congestion so you can cough it up and get it off your chest. It also contains Pseudoephedrine, an effective decongestion to clear nasal and sinus congestion, making breathing easier.
