Promethazine suppository is used to prevent and treat nausea and vomiting related to certain conditions (e.g., motion sickness, before/after surgery). It is also used to treat allergic symptoms such as rash, itching, and runny nose. It may be used for a short time to treat a runny nose due to the common cold. It may also be used to help you feel calmer before/after surgery or to help certain narcotic pain relievers (e.g., meperidine) work better. The suppository form is used when medications cannot be taken by mouth. Promethazine is an antihistamine. It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. Its other effects (e.g., anti-nausea, calming, pain relief) may work by affecting other natural substances (e.g., acetylcholine) and by acting directly on certain parts of the brain.
