Zofran Kidney Birth Defect Claims

When prescribed for morning sickness in pregnant women, Zofran® (or its generic, ondansetron) may increase the risk of having a baby with a birth defect by as much as 30%. This includes certain kidney defects including absence or mal-development of one kidney.


Studies Involving Zofran

According to a 2011 study performed by a grant from the Centers for Disease Control and Prevention (CDC), Zofran doubles the risks of birth defects. A Danish study which followed over 900,000 pregnant women who took Zofran, similarly concluded there was a two-fold increase in infant heart defects.

Evidence supporting the cause-effect relationship between Zofran used during pregnancy and birth defects continues to grow. In 2013, a study linked Zofran with a 20% overall increased risk of birth defects. Researchers also found a 6-fold increased risk of kidney defects, described as “obstructive defects of renal pelvis and ureter,” but the estimate was based on small numbers and was imprecise.

In June, 2014, the Toronto Star published its own investigative findings linking Zofran taken by pregnant mothers to kidney defects.

“At least 20 Canadian women treated with ondansetron for vomiting in pregnancy experienced serious suspected side-effects, including two infant deaths and multiple cases of newborns with heart defects and kidney malformations, according to a Star analysis of 2012 records.”

The FDA has recently cautioned against the use of Zofran during pregnancy due to the risk of birth defects.


If You Took Zofran During Pregnancy And Gave Birth To A Child With A Kidney Defect, You And Your Child May Be Entitled To Compensation, including:

  1. Reimbursement for all past and future medical expenses relating to the treatment of the Kidney defect;
  2. Compensation for yours or your child’s past and future pain and suffering arising out of the Kidney defect;
  3. Punitive damages (sought to deter and punish the drug company for encouraging the use of Zofran under circumstances that created an unreasonable risk of harm to your child).
