Topamax Lawsuit

Topamax manufacturers added the birth defect warnings you see in today’s prescribing information in 2011— three years after published studies revealed a 21 percent increased risk of oral clefts and only after the FDA required the labeling change. Families blame Janssen Pharmaceuticals Inc. and its drug Topamax for their loved ones’ birth defects, claiming had Janssen adequately warned about the drug’s risks, women would have chosen other treatment options.

*Please seek the advice of a medical professional before discontinuing the use of this drug.

Women who took Topamax sought legal compensation against the drug's manufacturer claiming it caused the following during pregnancy:

  • Cleft Palate
  • Cleft Lip
  • Other Birth Defects

Number of Lawsuits More than 130

Plaintiff Injuries Birth defects, specifically cleft palate and cleft lip

Defendants Janssen Pharmaceuticals Inc. (formerly Ortho-McNeil), a Johnson & Johnson subsidiary

Litigation Status Philadelphia Court of Common Pleas closed the Topamax mass tort program on March 17, 2016

Notable Settlements $11 million and $4 million

Haley Powell was prescribed Topamax to treat migraines and hand tremors. She had been taking the prescription drug for more than a year when she became pregnant with her son, Brayden Gurley, in 2007. Brayden was born with a cleft lip. The birth defect also caused nasal malformations and will require him to have at least five surgeries before he turns 21.

April Czimmer was also prescribed Topamax to treat migraines. She took the drug from August 2006 to February 2007. Her son, Blake, was born with a cleft lip and cleft palate in September 2007. Though Czimmer eventually stopped taking Topamax, she used the medicine early in her pregnancy, which is when the Centers for Disease Control (CDC) says oral clefts occur.

These women are among the hundreds of people who sued Janssen over allegations that the company failed to adequately warn that its drug Topamax causes birth defects.

Topamax, also known by its generic name topiramate, belongs to a category of drugs known as anticonvulsants. Doctors prescribe it to treat epilepsy and to prevent migraine headaches, as well as for off-label, or unapproved, uses. Janssen Pharmaceuticals (formerly Ortho-McNeil) is a Johnson & Johnson subsidiary.

Topamax is tied to birth defects, including:

  • Cleft lip and cleft palate (which can lead to ear infections and difficultly eating or talking)
  • Hypospadias (a penile defect in male infants)
  • Limb malformations
  • Lung defects
  • Heart defects
  • Spina bifida

People who sued Janssen over Topamax say the company:

  • Negligently designed and marketed Topamax
  • Knew about Topamax’s birth defect risks but failed to warn health care professionals
  • Intentionally concealed information about the drug’s birth defect risks
  • Did not adequately label the drug

FDA Requires Birth Defect Warning, Lawsuits Follow

In 2008, studies revealed evidence that Topamax carries an increased risk of birth defects. The U.S. Food and Drug Administration (FDA) analyzed results of nearly 200 trials that indicated Topamax caused birth defects. Based on its review, the agency in 2011 required Topamax’s makers to add a warning in the drug’s prescribing information to highlight the increased risk of cleft palate and cleft lip.

At the time, Topamax had been on the market for 15 years without such warnings.

Topiramate Prescriptions

From January 2007 through December 2010, pharmacies dispensed about 32.3 million topiramate prescriptions, and about 4.3 million patients filled topiramate prescriptions from U.S. pharmacies.

Families of babies born with birth defects began filing lawsuits against Janssen in September 2011. Cases were filed under a mass tort program in the Philadelphia Court of Common Pleas. Brayden Gurley’s family sued as did Czimmer on behalf of her son.

By 2013, more than 130 cases were pending in Philadelphia’s Topamax docket. The basis of the Topamax legal claims was that Janssen had a legal duty to warn consumer of the risks but failed to do so.

Multimillion Dollar Topamax Verdicts

In late 2013, the first Topamax birth defect trials in the Philadelphia Court of Common Pleas resulted in winning verdicts for the plaintiffs. Juries awarded $4 million to Czimmer in October and nearly $11 million to Brayden Gurley’s family in November.


Two families who sued over Topamax birth defects won a combined $15 million in jury verdicts against the drug’s maker.

According to Janssen, instances of birth defects cannot necessarily be linked to Topamax because oral clefts are a common congenital birth defect affecting thousands of newborns annually. At trial, the company also argued that Topamax’s labels adequately reflected what it knew at the time of the plaintiffs’ alleged injuries.

However, plaintiffs argued that the company knew about the birth defect risks as early as 1997, but failed to warn doctors and even concealed safety reports in 2003 and 2005.

Czimmer’s trial lasted 12 days. Jury deliberations began on Oct. 30, 2013. That same day, the jury returned a $4 million verdict against Janssen, including $562,184.68 in future health care expenses and $3,440,000 for pain and suffering.

A jury awarded Brayden Gurley’s family nearly $11 million in November 2013 following seven hours of deliberation. The verdict included $335,000 for future medical expenses and $10.6 million for non-economic losses (e.g., pain and emotional distress). The court later added $700,000 to the award, bringing the total to about $11.7 million.

Status of Topamax Lawsuits

The juries that delivered the 2013 Topamax verdicts ultimately found that Janssen failed to warn doctors about the full extent of Topamax’s birth defect risks. They also determined that the company’s negligence was a substantial factor in causing the plaintiffs’ injuries.


Despite Janssen’s attempts to appeal its loses, judicial panels affirmed the multimillion dollar Topamax verdicts against the company.

Janssen appealed both verdicts and lost in 2015. In Czimmer’s case, the Pennsylvania Superior Court affirmed the lower court’s verdict and rejected a subsequent bid from Janssen to reconsider. A judicial panel in the Superior Court of Pennsylvania also upheld the trial court’s decision in the case brought by Brayden Gurley’s family.

Meanwhile, J&J agreed to settle 76 other Topamax cases pending in Philadelphia Court of Common Pleas. The court closed the Topamax mass tort program on March 17, 2016.

The U.S. Department of Justice also came down on Topamax makers in 2010 for promoting off-label uses for Topamax, such as treatment of bipolar disorder and alcohol dependency, resulting in an $81 million fine.
