USES: Promethazine injection is used to treat nausea and vomiting related to certain conditions (e.g., after surgery, motion sickness).

The injectable form may be used to treat milder allergic reactions when you cannot take another medication by mouth. It may also be used before/after surgery, other procedures, or labor and delivery to help you feel calmer, to prevent nausea/vomiting, and to help certain narcotic pain relievers (e.g., meperidine) work better.Promethazine is an antihistamine (phenothiazine type). 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.This medication should not be used in children younger than 2 years.
