Robitussin Cough & Chest Congestion review
Controls coughs and helps clear chest congestion.It contains both a cough suppressant Dextromethorphan which helps quieten the cough for up to 8 hours and an expectorant Guaiphenesin which helps increase the flow of natural secretions along the lower respiratory tract.This combination works together to help control an irritating persistent cough with occasional phlegm.
