Patients may differ in how slowly or quickly their body breaks down ondansetron due to the function of a certain enzyme called P450 2D6 (CYP2D6). A genetic test may be performed to see how a patient’s enzymes function. This medicine may not work well in patients who break down ondansetron faster than normal.
This medicine is typically given 30 minutes before the start of chemotherapy.

May be taken as a liquid by mouth
