What is Zofran?
Zofran and generic versions of ondansetron are approved by the United States Food and Drug Administration to prevent nausea and vomiting caused by chemotherapy, radiation therapy, and surgery. It is in a class of drugs known as 5-HT3 receptor antagonists that work by blocking the action of serotonin, a natural chemical produced by the human body that can cause nausea and vomiting. It is not now—and has never been—approved to treat morning sickness.
Risks for Babies
The safety of Zofran for treating morning sickness has not been established. The FDA has not found Zofran to be safe or effective for treatment of nausea and vomiting during pregnancy. Similarly, Canada’s The Star reported that regulatory authority Health Canada has discouraged Zofran’s use in expectant mothers, warning doctors that “the safety of ondansetron for use in human pregnancy has not been established.”
A 2012 study by the U.S. Centers of Disease Control and Prevention and the Slone Epidemiology Center at Boston University, has reported that taking ondansetron in the first trimester of pregnancy doubles the risk of cleft palate in newborns. The study included more than 9,000 women and analyzed data from the National Birth Defects Prevention Study. Another study that included all women giving birth in Denmark between 1997 and 2010 (903,207 births) found the risk for major congenital heart defects doubled with use of Zofran to treat nausea and vomiting during the first trimester. In 2006, a Hong Kong-based study showed Zofran readily crosses the human placenta in the first trimester of pregnancy and was detected in every sample of fetal tissue taken among forty-one patients.
Pharmaceutical giant GlaxoSmithKline (GSK) developed ondansetron (originally marketed under the brand name Zofran) the mid-1980s. London-based GSK is one of the top ten pharmaceutical companies in the world in terms of sales.
The FDA first approved Zofran in 1991. Its only approved uses are for chemotherapy, radiation therapy, and post-operative related nausea and vomiting. GSK’s patent expired in 2006. The FDA approved the first generic versions of ondansetron the same year. GSK continued to market and sell Zofran even after generics became available.
In 2006—the final year of GSK’s patent protection on the drug—Zofran ranked number 20 in brand name drug sales in the U.S. with sales of $1.3 billion in the first 9 months of 2006 (80% from the U.S.). Some of these blockbuster sales resulted from prescriptions to pregnant women for morning sickness—again, a use not approved by the FDA.
Between 1983 and 2013, no drug was approved for use to treat morning sickness. The drug Bendectin (pyridoxine/doxylamine) had been removed from the market in 1983, but the pyridoxine / doxylamine combination continued on the market under different brand names in Canada and elsewhere for the next thirty years. Doctors then began prescribing drugs off-label—most commonly, Zofran—for the non-approved use of alleviating pregnancy-related nausea and vomiting.
After years of studies, the FDA approved the return of the combination of pyridoxine and doxylamine under the new brand name Diclegis in 2013. Even after the approval of Diclegis for morning sickness, approximately one million women last year were still prescribed Zofran or a generic equivalent of ondansetron.
What Does This Mean for You?
If you had a baby born with a cleft palate or congenital heart defect after taking Zofran for morning sickness during your first trimester of pregnancy, you and your child may be legally entitled to compensation for pain and suffering, medical costs, loss of income, emotional distress and other damages.
