I think it's also important to keep in mind that the risks of any medication -- whether it's ondansetron or any other medication -- need to be balanced against the risks of inadequate treatment or no treatment, particularly in those patients that have severe nausea and vomiting in pregnancy, or hyperemesis gravidarum, those conditions carry some real risks themselves -- dehydration, electrolyte abnormalities -- and a lot of these patients require admission to the hospital if they're not adequately treated.
