Women and their doctors were never warned that taking Zofran for nausea during pregnancy could lead to babies being born with severe birth defects including heart defects, cleft palates and lips, club feet, and craniosynostosis. Instead, Zofrans’ manufacturer, GlaxoSmithKline, engaged in deceptive and illegal marketing, promoting Zofran for unapproved (“off-label”) use by pregnant women with morning sickness. GlaxoSmithKline failed to conduct a single study on the safety of using Zofran for pregnant women and never sought FDA approval to market the drug to pregnant women.

Who uses it and for what conditions?

Zofran is intended to be used by patients who suffer from nausea and vomiting as a result of undergoing chemotherapy and radiation. It is also prescribed to help control nausea in post-surgical patients. Despite the limited uses Zofran was approved for, GlaxoSmithKline marketed the drug off-label as a remedy for pregnancy-induced morning sickness.
