Little published information is available on the clinical use of ondansetron during breastfeeding, although it is apparently frequently used for nausea after cesarean section, usually in doses of 4 to 8 mg intravenously.[1][2] Use after cesarean section appears to not affect the onset of breastfeeding.[3] No adverse infant effects have been reported and the drug has been used in infants.[4] If ondansetron is required by the mother, it is not a reason to discontinue breastfeeding; however an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
