Treating cough, congestion, and other upper respiratory symptoms caused by allergies or the common cold. It may also be used for other conditions as determined by your doctor.
Codeine/phenylephrine/promethazine syrup is a phenothiazine antihistamine, decongestant, and narcotic cough suppressant combination. The antihistamine works by blocking the action of histamine to reduce the symptoms of an allergic reaction, such as runny nose and sinus drainage. The decongestant works by constricting blood vessels, which shrinks swollen and congested nasal tissue. The cough suppressant works in the brain to decrease the cough reflex.

- you have certain lung or breathing problems (eg, asthma, chronic obstructive pulmonary disease [COPD], sleep apnea), or if you have a fever and a productive cough
