Key takeaways
Granisetron (Kytril) and Sancuso (granisetron) are both antiemetics used to prevent nausea and vomiting caused by chemotherapy. However, they differ in their forms and administration. Granisetron (Kytril) is available as an oral tablet or intravenous infusion, while Sancuso is a transdermal patch. You take granisetron tablets about an hour before chemotherapy, but you apply the Sancuso patch 1-2 days before chemotherapy, and it can stay on for up to 7 days. Granisetron tablets can be more expensive and are not suitable for children, whereas the Sancuso patch is a good option for those who prefer not to take pills. Both medications can cause serotonin syndrome and severe constipation, but the Sancuso patch also requires you to avoid direct sunlight and heat sources.
