Administration: Read the Medication Guide provided by your pharmacist before you start using granisetron and each time you get a refill. If you have any questions, ask your doctor or pharmacist. This medication is given as directed by your doctor, usually 30 minutes before chemotherapyon day 1 of your treatment cycle. It is given by slow injection under the skin on the back of your upper arm or the skin on your abdomen by a health care professional. The dosage is based on your medical condition and response to treatment. This medication is a long-acting form of granisetron so you should not receive it more often than once every 7 days. Tell your doctor if your nausea or vomiting does not get better or if it gets worse.

Details: Granisetron is used to help prevent nausea and vomiting caused by cancer chemotherapy. It works by blocking the effect of a natural substance in your body (serotonin) that may cause nausea or vomiting.
