Abstract
Summary: Ondansetron is a 5-hydroxytryptamine receptor antagonist which is known to be a highly effective anti-emetic drug for chemotherapy-associated nausea and vomiting and for postoperative nausea. We report here a case where ondansetron was used in severe hyperemesis gravidarum to avoid parenteral nutrition. The drug was used intermittently in every trimester with no apparent adverse effects on mother or infant.
