What is acetaminophen, codeine, guaifenesin, and pseudoephedrine (Maxiflu CD, Maxiflu CDX)?
Guaifenesin is an expectorant. It helps loosen mucus congestion in your chest and throat, making it easier to cough out through your mouth.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
The combination of acetaminophen, codeine, guaifenesin, and pseudoephedrine is used to treat stuffy nose, cough, pain and fever, and to reduce chest congestion caused by upper respiratory infections or the common cold.
Acetaminophen, codeine, guaifenesin, and pseudoephedrine may also be used for other purposes not listed in this medication guide.

Read the label of any other medicine you are using to see if it contains acetaminophen (sometimes abbreviated as "APAP"), guaifenesin, or pseudoephedrine.
