Promethazine DM is a prescription medication that combines promethazine, an antihistamine, and dextromethorphan, a cough suppressant. It's primarily used to relieve symptoms associated with the common cold, allergies, or other respiratory illnesses, such as cough, runny nose, sneezing, and itching of the nose or throat. Promethazine works by blocking the effects of a natural chemical in the body to reduce allergy symptoms, while dextromethorphan suppresses the cough reflex in the brain.
