Answer by DrLact: About Ondansetron Injection usage in lactation

Little published information is available on the clinical use of Ondansetron Injection 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 Injection 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.
