Question: are nyquil and robitussin the same?
Answer: Nyquil Cold And Flu (Acetaminophen / Dextromethorphan / Doxylamine) Breaks up mucus that causes cough. Robitussin (Guaifenesin) is a useful medicine for loosening congestion in your chest and throat, but it doesn't last as long as other guaifenesin products. Relieves cold and flu symptoms, and helps you sleep.
