WARNING: Promethazine should not be used in children younger than 2 years since it might cause slow/shallow breathing (respiratory depression), which in some cases could be fatal. This problem has occurred even with normal doses in this age group.

Use this drug with caution in children older than 2 years. The lowest effective dosage should be used, and other drugs that affect breathing should be avoided. Seek immediate medical attention in the unlikely event that slow/shallow breathing occurs.

In children, use drugs for nausea only in cases of prolonged vomiting with a known cause. Avoid use of promethazine in children with liver disease (including possible Reye's syndrome).

USES: Promethazine injection is used to treat nausea and vomiting related to certain conditions (e.g., after surgery, motion sickness). It is also used with other medication to treat life-threatening allergic symptoms (anaphylaxis) and reactions to blood products. 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.
