Chlorpheniramine/ codeine suspension is used for:
Relieving runny nose; sneezing; coughing; itchy, watery eyes; or itching of the nose and throat caused by colds, upper respiratory infections, and allergies. It may also be used for other conditions as determined by your doctor.
Chlorpheniramine/codeine suspension is an antihistamine and narcotic cough suppressant combination. The antihistamine works by blocking the action of histamine, which helps reduce symptoms, such as itchy, watery eyes and sneezing. The cough suppressant works in the brain to help decrease the cough reflex, which reduces a dry cough.
