Zofran

Zofran medication is used to prevent symptoms of nausea and vomiting. Ondansetron works in the stomach to block the signals to the brain that cause nausea and vomiting. It is particularly used to avoid such symptoms after cancer treatments such as chemotherapy or radiation therapy as well as after surgery. Zofran works by restricting the action of a natural substance that occurs within the body and is responsible for causing vomiting.
