The Tylenol lawsuit claims that the use of acetaminophen, the active ingredient in Tylenol, during pregnancy may increase the risk of autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) in children. This lawsuit is based on scientific studies suggesting a potential link between prenatal acetaminophen exposure and these developmental disorders.
About Tylenol and ASD/ADHD
Research into the link between acetaminophen (Tylenol) and autism spectrum disorder (ASD) or attention deficit/hyperactivity disorder (ADHD) has been ongoing for several years. Initial studies, such as those funded by the National Institute of Health (NIH) suggested a potential association between prenatal acetaminophen exposure and an increased risk of these neurological disorders. For example, a 2019 study analyzed umbilical cord blood and found that higher levels of acetaminophen were associated with a greater risk of ASD and ADHD in children.
Tylenol Lawsuit Updates
November 2024: Judge Denise L. Cote granted summary judgment in favor of the defendants in the federal multidistrict litigation (MDL). Plaintiffs have appealed their decision.
October 2024: Plaintiffs filed an appeal in the 2nd Circuit Court of Appeals, arguing that the summary judgment granted in favor of defendants disregarded valid scientific methodologies. The outcome of this appeal could potentially reopen the case if the court rules in favor of the plaintiffs.
About Prenatal Tylenol Usage
The potential link between Tylenol (acetaminophen) use during pregnancy and the development of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) in children has been a topic of considerable research and debate. Some studies have suggested that prolonged use of acetaminophen during pregnancy might be associated with a higher risk of these neurodevelopmental disorders. For instance, a 2018 meta-analysis found a 20 percent higher risk of autism and a 30 percent higher risk of ADHD in children whose mothers used acetaminophen during pregnancy. However, these studies are observational and cannot definitively establish causation.
Similar Lawsuits
A few notable lawsuits involve prenatal use of medications similar to Tylenol cases include:
Depakote Lawsuits: This antiseizure medication was linked to spina bifida and other congenital defects when used during pregnancy. Manufacturer Abbott Laboratories agreed to a $1.5 billion settlement in 2012 to resolve criminal and civil investigations related to the off-label promotion of the drug. Additionally, there have been mixed outcomes in individual birth defect cases, with some resulting in multi-million-dollar verdicts for plaintiffs.
Paxil Lawsuits; The antidepressant Paxil has been associated with heart defects and other congenital defects when taken during pregnancy. GlaxoSmithKline (GSK) settled approximately 800 birth defect lawsuits for about $1.14 billion in 2010. GSK also agreed to a $3 billion settlement to resolve criminal and criminal liability for promoting Paxil and other drugs for unapproved uses and failing to report safety data.
These cases, like the Tylenol lawsuits, often focus on the argument that manufacturers did not provide sufficient warnings about the potential risks of using these medications during pregnancy.
Tylenol Related Complications
Prenatal use of Tylenol (acetaminophen) has been associated with several potential links, although the research is ongoing and not entirely conclusive, including:
Neurodevelopmental Disorders: Some studies suggest a possible link between prenatal acetaminophen exposure and an increased use of neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD).
Reproductive and Urogenital Disorders: Some evidence exists indicating that acetaminophen use during pregnancy might affect the development of the reproductive system and urogenital tract in the fetus.
What is Johnson & Johnson Liability?
Tylenol is manufactured by Johnson & Johnson, specifically through its subsidiary McNeil Consumer Healthcare. Tylenol, which contains the active ingredient acetaminophen, has been a widely used over-the-counter pain reliever and fever reducer since its introduction in 1955.
The liability in the Tylenol lawsuits centers on claims that Johnson & Johnson failed to adequately warn consumers about the potential risks of using acetaminophen during pregnancy. Plaintiffs argue that prenatal exposure to acetaminophen may increase the risk of neurodevelopmental disorders. Additional arguments include negligence and misrepresentation.
Tylenol Lawsuits
Three specific lawsuits related to Tylenol and its alleged link to autism spectrum disorder and attention deficit hyperactivity disorder include:
Multidistrict Litigation (MDL) in New York: This MDL consolidates numerous lawsuits filed by parents who claim that prenatal use of Tylenol caused their children to develop ASD or ADHD. The plaintiffs argue that Johnson & Johnson and retailers failed to warn of potential risks. The outcomes of these cases are still pending, with many expected to proceed in state courts.
California State Court Cases: In California, several lawsuits have been filed against Johnson & Johnson and various retailers. These cases are part of a broader effort to hold manufacturers accountable for not providing adequate warnings of the risks of acetaminophen use during pregnancy.
Connecticut State Court Cases: In Connecticut, parents have filed lawsuits alleging that prenatal exposure to Tylenol led to their children developing ASD or ADHD. These cases are being closely watched as they progress through the courts.
Despite their differences, these Tylenol lawsuits have in common:
Failure to Warn: Plaintiffs claim Johnson & Johnson and other manufacturers failed to provide adequate warnings about the potential risks of using acetaminophen during pregnancy, arguing that they would have chosen alternative pain relief options if they had known of the risks.
Negligence: The lawsuits allege that manufacturers were negligent in their duty to ensure the safety of their products. This includes accusations that they did not conduct sufficient research or adequately monitor the effects of acetaminophen on fetal development.
Misrepresentation: Plaintiffs also argue that the manufacturers misrepresented the safety of acetaminophen for pregnant women, arguing that marketing materials and product labels suggested that acetaminophen was safe for use during pregnancy without adequately disclosing the potential risks.
Lawsuit Eligibility
- Prenatal Use of Tylenol
- Diagnosis of Autism or ADHD
- Evidence of Medical Records
To be eligible for a Tylenol lawsuit, the plaintiff (typically the mother) must have used Tylenol or other acetaminophen products regularly during pregnancy. The child must have been diagnosed with autism spectrum disorder or attention deficit hyperactivity disorder. Plaintiffs must also provide medical records and other evidence to support claims of acetaminophen use during pregnancy and subsequent diagnosis of ASD or ADHD in the child.
