Codeine is a narcotic cough suppressant. It affects the signals in the brain that trigger cough reflex.
Guaifenesin is an expectorant. It helps loosen 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).
Codeine, guaifenesin, and pseudoephedrine is a combination medicine used to treat stuffy nose, cough, sinus congestion, and chest congestion caused by allergies, the common cold, or the flu.
