Pseudoephedrine/ codeine/ guaifenesin is used for:
Relieving congestion and cough due to colds, flu, or hay fever. It may also be used for other conditions as determined by your doctor.
Pseudoephedrine/codeine/guaifenesin is a decongestant, cough suppressant, and expectorant combination. The decongestant works by constricting blood vessels and reducing swelling in the nasal passages. The cough suppressant works in the brain to help decrease the cough reflex to reduce a dry cough. The expectorant loosens mucus and lung secretions in the chest and makes coughs more productive.
