codeine syrup is used for:
Treating cough 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.
Promethazine/codeine syrup is a phenothiazine antihistamine 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 cough suppressant works in the brain to decrease the cough reflex.
Do NOT use promethazine/ codeine syrup if:
you are allergic to any ingredient in promethazine/codeine syrup, any other codeine-related medicine (eg, oxycodone), or phenothiazines (eg, chlorpromazine)
you have severe drowsiness
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
you have diarrhea caused by food poisoning or antibiotic use
you are taking sodium oxybate (GHB)
the patient is a child and has just had surgery to remove tonsils or adenoids
Contact your doctor or health care provider right away if any of these apply to you.
