What is Robitussin?
Robitussin is an OTC cough suppressant. Robitussin works by loosening congestion in your chest, which makes it easier to express your cough. It is mostly used for symptoms of a cold, but can also be used to treat certain allergy responses.
What is the difference between Robitussin DM and Children's?
Robitussin DM contains the active ingredient dextromethorphan which relieves coughing by reducing brain activity which gives you the annoying urge to cough. In children's Robitussin, there is far less dextromethorphan HBr at 5mg/serving instead of the 20mg/dose in the classic Robitussin DM.
