Robitussin helps to loosen congestion in your chest, making it easier to cough out. It can be used to relieve symptoms when you have a cold or allergies.
What Is Robitussin DM?
Robitussin DM contains two active ingredients, dextromethorphan and guaifenesin. Dextromethorphan relieves coughing by decreasing activity in your brain that gives you the urge to cough. Guaifenesin helps to loosen up mucus in your throat and lungs causing chest congestion.
How Long Does Robitussin Take To Work?
As soon as dextromethorphan enters the blood stream, it starts to work with your body. This usually happens around 15 minutes of ingestion. The peak efficiency of the medicine occurs at 2 hours.
