Granisetron Dosing

For the prevention of nausea and vomiting due to radiation, granisetron dosing typically starts at 2 mg once daily. To help prevent nausea and vomiting associated with chemotherapy, you can take 2 mg once daily or 1 mg twice daily. To help ensure the effectiveness of the medication, be sure to take your granisetron dosage within one hour before radiation or chemotherapy.

Granisetron Dosage: An Introduction

The dose of granisetron hydrochloride (Kytril®) that your healthcare provider recommends will vary depending on a number of factors, including:
  • Whether you are having radiation or chemotherapy
  • Other medications you may be taking
  • Other medical conditions you may have.
As is always the case, do not adjust your granisetron dose unless your healthcare provider specifically instructs you to do so.
