promethazine (injection) (cont.)

What should I discuss with my health care provider before I receive promethazine injection (Adgan, Anergan 50, Phenergan)?

You should not use this medication if you are allergic to promethazine or to similar medicines such as chlorpromazine (Thorazine), fluphenazine (Prolixin), mesoridazine (Serentil), perphenazine (Trilafon), prochlorperazine (Compazine), thioridazine (Mellaril), or trifluperazine (Stelazine).

To make sure you can safely use promethazine, tell your doctor if you have any of these other conditions:

FDA pregnancy category C. It is not known whether promethazine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.

It is not known whether promethazine passes into breast milk or if it could harm a nursing baby. Do not receive this medication without telling your doctor if you are breast-feeding a baby.

How is promethazine injection given (Adgan, Anergan 50, Phenergan)?

Promethazine is given as an injection deep into a muscle. You will receive this injection in a clinic or hospital setting. This medication is usually given every 2 to 4 hours depending on the condition it is used for.

Promethazine injection is usually given for only a short time until no longer needed or until you can take promethazine by mouth.

This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you have recently received promethazine injection.
