A large Danish study in the New England Journal of Medicine shows no significant association between the antiemetic ondansetron and adverse pregnancy outcomes.

In this retrospective cohort study, ondansetron had been prescribed for nausea and vomiting in almost 2000 of some 600,000 pregnancies. Ondansetron users were no more likely than nonusers to experience spontaneous abortion or stillbirth, or to have preterm delivery, a small-for-getational-age infant, or an infant with a major birth defect.
