How it works
Dayquil Cold And Flu (Acetaminophen / Phenylephrine / Dextromethorphan) is a combination medicine that treats cold and flu symptoms. Acetaminophen relieves pain and reduces fever. Dextromethorphan is a cough suppressant. Phenylephrine is a decongestant that clears your sinuses.
Mucinex D (Guaifenesin / Pseudoephedrine) is a combination medicine. Guaifenesin (an expectorant) breaks up and thins out mucus. Pseudoephedrine (a decongestant) clears your sinuses.
