What is Guiatuss AC (codeine and guaifenesin)?
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.
Codeine and guaifenesin is a combination medicine used to treat cough and chest congestion caused by allergies, the common cold, or the flu.
This medicine will not treat a cough that is caused by smoking, asthma, or emphysema.
Codeine and guaifenesin may also be used for purposes not listed in this medication guide.
