It works by blocking serotonin, a natural substance in the body that causes nausea and vomiting. Granisetron comes as a tablet and a solution (liquid) to take by mouth. When taken to prevent nausea and vomiting caused by chemotherapy, Granisetron is usually taken 1 hour before chemotherapy is begun. A second dose may be taken 12 hours after the first dose. When taken to prevent nausea and vomiting caused by radiation, Granisetron is usually taken within 1 hour before treatment. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Granisetron exactly as directed.
