Ondansetron Effective for moderate-to-severe nausea and vomiting of pregnancy (NVP) and hyperemesis gravidarum (HG) refractory to first-line agents. Early reports of cleft palate risk (Danish cohort, Pasternak 2010) were not consistently replicated in subsequent larger studies including a 2014 Swedish cohort (>1.8 million pregnancies) which found no significant increase in major malformations. Current consensus supports use when first-line options fail, with shared decision-making in T1. Small signal of cardiac septal defects in some studies has not been confirmed. | 5-HT3 Antagonist | | caution |
