Why do I need this medicine?
Ondansetron is used to prevent nausea and vomiting associated with cancer chemotherapy (cancer treatment), or radiation therapy or nausea and vomiting after surgery.
How do I take this medicine?
Take Ondansetron exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
If you are taking this medicine to prevent nausea and vomiting due to chemotherapy, take it 30 minutes before your chemotherapy treatment.
If you are taking Ondansetron to prevent nausea and vomiting due to radiation therapy, take it 1-2 hours before your radiation therapy.
If you are taking this medicine to prevent nausea and vomiting after an operation, take it 1 hour before your operation.
Ondansetron may be taken with or without food.
Ondansetron is available as an orally disintegrating tablet (orodispersible).
If you are taking the orodispersible tablet:
1. Remove it from the foil only just before you take it. Do not leave the orodispersible tablet exposed to air. Do not push the orodispersible tablet through the foil as it is fragile and easily broken.
2. Remove the orodispersible tablet with dry hands by peeling the backing off the foil and tipping the tablet onto your dry hands.
3. Place the orodispersible tablet directly on your tongue as soon as it is taken out of the foil. The orodispersible tablet will immediately start to melt on the tongue. It can then be swallowed with or without water.
Do not cut, break or crush the orodispersible tablets.
