Compazine (Prochlorperazine) is used to treat severe nausea and vomiting from certain causes such as surgery, or cancer. This medication belongs to a class of drugs known as phenothiazines. This medication works by blocking the action of a chemical called dopamine in the brain. This stops nausea messages from being sent to a part of your brain called the "vomiting centre".
We currently have the brand Compazine from New Zealand (Buccastem) by Alliance Pharmaceuticals and the United Kingdom (Stemetil) manufactured by Sanofi. The generic Prochlorperazine comes from Canada by a different manufacturer.
