Update: Zofran Lawsuit ‘Short Form Complaint’ Speeds Up Filing Process

July 6, 2016 – In one of the first lawsuits to be filed using the new “Short Form Complaint,” a mother from Sandusky, Ohio claims her son was born with an atrial septal defect, ventricular septal defect and cleft palate after being exposed to Zofran in the womb. The mother also claims her child has suffered “issues with vision and hearing,” likely as a result of her cleft palate. The complaint was filed June 24, 2016 under case number 1:16-cv-11281-FDS.

Overview

Zofran is an anti-nausea medication that blocks the actions of chemicals that can trigger nausea and vomiting. The drug is indicated for the treatment of these conditions when caused by surgery or cancer medication. Zofran is manufactured by GlaxoSmithKline (GSK), and was approved by the U.S. Food & Drug Administration (FDA) in 1991.

What’s the Problem?

Although not approved for this use, Zofran is commonly prescribed “off-label” for the treatment of nausea and vomiting associated with morning sickness. Off-label prescribing is legal and done at the doctor’s discretion; however, when prescribed in this capacity, Zofran has been linked to birth defects.

Zofran Heart Defect Study

A 2013 Danish Study titled “Ondansetron use in early pregnancy and the risk of congenital malformations” found that women who used Zofran during their 1st trimester of pregnancy were twice as likely to give birth to babies with congenital heart defects compared to pregnant women who did not take the drug.

The study’s cohort included all women who had babies in Denmark from 1997 to 2010. The primary outcome was the prevalence of major congenital birth defects according to the EUROCAT classification system, with specific subgrouping among 1st trimester Zofran users compared to non-users. Exposure was defined in women who filled at least 1 prescription for Zofran during their 1st trimester.

The researchers identified 897,018 Danish births between 1997 and 2010. During this period, 1,248 pregnant women filled a Zofran prescription during their 1st trimester. Of these, 58 (4.7%) gave birth to babies with severe congenital malformations compared to 3.5% of the 31,357 women who did not take Zofran in pregnancy.

Most of the defects identified by the study were coronary artery abnormalities such as atrial septal defects. “We found a doubling in the prevalence of major congenital heart defects in children whose mothers redeemed a prescription of ondansetron in the first trimester of pregnancy,” the authors concluded.

What is an Atrial Septal Defect?

An atrial septal defect, or ASD, is a congenital (present at birth) abnormality characterized by a hole in the upper 2 chambers of the heart (atria). As a baby develops in the womb, a wall called the interatrial septum forms which divides the upper chamber into a left and right atrium. An abnormal formation of the interatrial septum may result in a hole, or atrial septal defect.

Symptoms

Signs and symptoms of an atrial septal defect may include:

  • Difficulty breathing (dyspnea)
  • Respiratory infections
  • Heart palpitations
  • Shortness of breath with activity

Treatment

Atrial septal defects may not require treatment in patients who are asymptomatic, or who have minor symptoms. Surgery to close the ASD may be recommended if the hole causes a large amount of shunting, the heart is swollen, or other symptoms occur.

In recent years, a procedure has been developed to close an atrial septal defect without surgery. The procedure involves placing a closure device into the heart through catheters. The physician makes a small incision in the groin, then inserts the catheters into a blood vessel and up into the heart. The closure device is then placed across the defect and the hole is closed.
