Chlorpheniramine/ codeine/ pseudoephedrine liquid is used for:
Treating symptoms of the common cold, flu, or hay fever, and other upper respiratory allergies, such as cough, congestion, runny nose, sneezing, itching of the nose and throat, and itchy, watery eyes. It may also be used for other conditions as determined by your doctor.
Chlorpheniramine/codeine/pseudoephedrine liquid is a narcotic antitussive (cough suppressant), antihistamine, and decongestant combination. The antitussive works by suppressing the cough center in the brain. The antihistamine works by blocking the action of histamine, which reduces the symptoms of an allergic reaction, such as itchy, watery eyes and runny nose. The decongestant shrinks swollen nasal passages, which relieves nasal congestion.
