Pseudoephedrine/Codeine/Guaifenesin/Acetaminophen is used for:
Relieving pain, congestion, cough, fever, and throat and airway irritation due to respiratory tract infections and other related conditions. It may also be used for other conditions as determined by your doctor.
Pseudoephedrine/Codeine/Guaifenesin/Acetaminophen is a decongestant, narcotic cough suppressant, expectorant, and analgesic combination. The decongestant works by constricting blood vessels and reducing swelling in the nasal passages. The expectorant works by loosening mucus and lung secretions in the chest, making coughs more productive. The cough suppressant works in the brain to help decrease the cough reflex. The analgesic works in the brain to reduce pain and fever.
