Women in Pennsylvania and Massachusetts have filed lawsuits alleging that their children were born with heart defects and other congenital birth defects caused by taking the drug Zofran during pregnancy. The lawsuits accuse GlaxoSmithKline, the manufacturer of Zofran, of promoting the drug to treat morning sickness and nausea during pregnancy despite the fact that it was never approved for pregnant women by the FDA.
The first Zofran lawsuit filed against GlaxoSmithKline involved a Pennsylvania woman whose two children were born with serious congenital heart defects after she was prescribed the anti-nausea drug during pregnancy. The second lawsuit, recently filed in Massachusetts, involves a women whose daughter was born with birth defects, including heart defects, after she was also prescribed the drug during her pregnancy.
Zofran (sold generically as ondansetron) was approved by the Food and Drug Administration in 1991 to treat nausea and vomiting in cancer patients who are undergoing chemotherapy or radiation therapy, as well as for patients who have undergone surgery. The drug works by affecting serotonin levels in the brain. Although the agency has not approved the drug for use during pregnancy, Zofran is sometimes prescribed off-label to relieve symptoms of nausea and vomiting with pregnant women.
According to the Zofran lawsuits filed against the company, GlaxoSmithKline knew as early as the 1980s about the potential risk of miscarriage and congenital birth defects for women who used the drug during pregnancy. The lawsuits allege that despite this knowledge, the drug company deliberately promoted Zofran for off-label use among pregnant women. The company continued to promote Zofran for these off-label uses despite the existence of other FDA-approved drugs such as doxylamine and pyridoxine to treat nausea, vomiting, and morning sickness in pregnant women, the lawsuits also allege.
In 2013, GlaxoSmithKline was forced to pay a $3 billion settlement with the U.S. Department of Justice for unapproved marketing practices concerning a number of medications, including Zofran. FDA rules specifically prohibit drug companies from promoting their products among patients or to treat conditions that have not been approved by the agency.
Zofran Linked To Increased Heart Defects, Birth Defects Risk
Recent studies have raised concerns about the danger of birth defects caused by taking Zofran while pregnant. In August 2013, a Danish study found that pregnant women who used Zofran were twice as likely to give birth to a child with heart defects and 30% more likely to give birth to a child with major congenital birth defects.
A second study published by the American Journal of Obstetrics and Gynecology in December 2014 also raised concerns about the risk of danger to the fetus caused by the use of Zofran during pregnancy. Most alarmingly, the study found that 1 million women who suffer from nausea and vomiting during pregnancy were prescribed Zofran each year, meaning that hundreds of thousands of children could be at risk of heart defects and other birth defects.
Studies have found that the risk of heart defects and other birth defects associated with the use of Zofran while pregnant occurs during the first trimester of pregnancy. Studies of other drugs that affect serotonin levels in the brain—including SSRI antidepressants such as Paxil, Prozac, and Zoloft—have shown that the chemical changes caused by these medications can affect the development of the fetus during the first trimester, increasing the risk of serious heart defects such as:
- Atrial Septal Defects (ASD) and Ventricular Septal Defects (VSD)
- Persistent Pulmonary Hypertension of the Newborn (PPHN)
- Hypoplastic Left Heart Syndrome (HLHS)
- Tetralogy of Fallot
- Patent Ductus Arteriosus (PDA)
