Zofran belongs to the group of medications called antiemetics. Zofran is used for the prevention of nausea (feeling of sickness) and vomiting during treatment for cancer (chemotherapy and radiotherapy) and for the prevention and treatment of nausea and vomiting after surgery. Treatments such as general anesthesia, cancer chemotherapy and radiotherapy are thought to cause the release of a natural substance (serotonin), which can cause you to feel sick and to vomit. Zofran helps to stop this from happening, thus preventing you from vomiting or feeling sick. Do not take more doses, or take them more often than your doctor prescribes. If, however, you vomit within one hour of taking your medicine, you should take the same amount of medicine again. If vomiting persists, consult your doctor. Ondansetron can be taken with or without food. Follow your doctor's dosing instructions very carefully. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
