Question: are dayquil and mucinex the same?
Answer: Mucinex D (Guaifenesin / Pseudoephedrine) is good if you have a stuffy nose and a cough with mucus, but it could keep you up at night. Dayquil Cold And Flu (Acetaminophen / Phenylephrine / Dextromethorphan) is a combination medicine that relieves multiple cold symptoms.
