Kytril (Granisetron) (Granisetron) — Uses, Dosage, Side Effects & Safety

Drug class: Antiemetic (5-HT3 receptor antagonist)

Overview

Kytril (Granisetron) is a prescription medicine used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, and surgery. It works by blocking serotonin, a natural substance in the body that can trigger nausea and vomiting. Granisetron is typically given before chemotherapy or radiation sessions to help control these side effects, making treatment more tolerable. It is available in several forms, including tablets, oral solution, and injection. Key points for patients: Take Kytril exactly as prescribed, usually before treatment.
