Methods The individual cases of adverse drug reactions retrieved from China adverse drug reaction database (from January 1, 2004 to September 30, 2022) and WHO Vigilyze (from inception to October 31, 2022) and other databases (from inception to December 31, 2023) were analyzed. Results In the serious adverse reaction report of ondansetron, adverse reactions such as anaphylactic shock, dyspnea, and liver dysfunction are prominent. ondansetron in pregnancy is associated with a risk of cleft lip and palate. If pregnant women use ondansetron before and after delivery, breastfeeding should be suspended. Conclusion Medical institutions should pay attention to the teratogenic risk of Ondansetron and weigh the risk and benifit before using it in pregnant women. The drug marketing authorization holder should update the drug labeling in time, strengthen the risk communication with medical institutions, and promote the rational use of medicines.
