1. WHAT GRANISETRON IS AND WHAT IT IS USED FOR
Granisetron belongs to a group of medicines called ‘5-HT3 receptor antagonists’ or ‘antiemetics’. Granisetron tablets are only

Granisetron is used to prevent nausea and vomiting (feeling and being sick) caused by other medical treatments, such as
chemotherapy or radiotherapy for cancer.
