It's an anti-emetic; it stops nausea. Very effective, but also quite sedating. In clinical settings, it's often used with narcotics such as Demerol to help potentiate the effect of the drug.
Brand name is Phenergan. For adults it is typically given in a 12.5 to 25 milligram dose, either in tablet, injectable, or suppository form. Commonly used in hospitals, it's a prescription drug.
Technically, it's an antihistamine anti-emetic and has could be used to stop an allergic response. However, in 17 years of clinical experience, I've never seen it used that way. For histamine blocking properties in allergic reactions, Benadryl is always the drug of choice.
