Someone suggests to take ondansetron the night before (12 hours before) the start of the chemo theraphy. Is it true?
Ondansetron is a medication used to prevent nausea and vomiting that can be caused by chemotherapy, radiation, or surgery. Ondansetron is designed to prevent nausea and vomiting from occurring, rather than treating it once it has begun. In order for ondansetron to work properly, you must take it as prescribed.
Typically ondansetron is taken 30 minutes before chemotherapy. Taking it the night before is not recommended. It could render it ineffective. You should follow the instructions of your doctor.
