For the prevention of nausea and vomiting due to chemotherapy, the recommended Kytril dosage is 2 mg once daily or 1 mg twice daily on the days of chemotherapy. To prevent nausea and vomiting caused by radiation, the recommended dosage is 2 mg once daily. Your Kytril dose should be taken one hour before chemotherapy or radiation.
The dose of Kytril® (granisetron hydrochloride) 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 Kytril dose unless your healthcare provider specifically instructs you to do so.
The recommended Kytril dose for the prevention of nausea and vomiting due to radiation is 2 mg once daily, taken within one hour before radiation.
The recommended Kytril dose for the prevention of nausea and vomiting due to chemotherapy is 2 mg once daily or 1 mg twice daily on the days of chemotherapy. Kytril should be taken within one hour before chemotherapy (and 12 hours later, when taken twice a day).
There is also an injectable form of Kytril that can be given by IV within 30 minutes before chemotherapy.
Considerations for people taking Kytril include the following:
- Kytril comes in tablet form. It is taken by mouth, usually one hour before chemotherapy or radiation. When used for radiation, it is taken once daily, and when used for chemotherapy, it is taken once or twice a day.
- Kytril can be taken with or without food. However, you may need to have an empty stomach for your chemotherapy or radiation. Be sure to ask your healthcare provider if you may take Kytril with food.
- For the medication to work properly, it must be taken as prescribed.
- If you are unsure about anything related to your Kytril dosage, please talk to your doctor, nurse, or pharmacist.
