A member asked:

Granisetron oral disintegrating 1 mg. tablet for chemo nausea is about equal to how many mgs. of oral disintegrating zofran (ondansetron) or zofran (ondansetron) regular pills?

A doctor has provided 1 answer

Zofran (ondansetron) dosing: As a single dose before certain chemotherapy regimes, Granisetron can be given as a single 2mg dose, and Zofran (ondansetron) as a single 24mg dose, but only for single day chemotherapy when a high amount of nausea is anticipated. Side effects may occur and you will need to discuss this with your oncologist.
