See also Warning Section.
This combination medication is used to treat symptoms caused by the common cold, flu, allergies, or other breathing illnesses (e.g., sinusitis, bronchitis). Promethazine codeine syrup dosage is an antihistamine that relieves watery eyes, itchy eyes/nose/throat, runny nose, and sneezing.

Giving more than the recommended dose or using this medication along with other cough-and-cold products has resulted in serious (even fatal) side effects, including slowed/stopped breathing. Talk to the doctor or pharmacist before giving other cough-and-cold medication that might contain the same or similar ingredients (see also Drug Interactions section). Ask about other ways to relieve cough and cold symptoms (such as drinking enough fluids, using a humidifier or saline nose drops/spray). Do not use this product to make a child sleepy.
