It's 25mg Promethazine
PROMETHAZINE (PhenerganÃ‚Â®) is an antihistamine. It relieves moderate to severe allergic reactions, reduces or prevents nausea and vomiting from illness or motion sickness, helps to make you sleep before surgery, and may help with pain relief or nausea after surgery
That pill will help nausea and make you VERY drowsy. They give it to patients along with pain shots to prevent sickness of the stomach. I'm new to this Forum...I just thought I'd let you know that. I know alot about those pills.
