Date Modified:

The Tylenol autism lawsuit is an ongoing class action lawsuit where parents claim that taking Tylenol or generic acetaminophen products during pregnancy led to their children being diagnosed with autism, ADHD, or other neurodevelopmental disorders. Plaintiffs in these lawsuits allege that the drug’s manufacturers negligently failed to warn consumers about the potential risks involved.

This nationwide legal action is brought forth by parents who took Tylenol during pregnancy and subsequently had children diagnosed with these disorders.


Latest Tylenol Autism Lawsuit Update

As of February 2024, Judge Cota is allowing the Mota plaintiffs to bring in an expert witness, epidemiologist Dr. Roberta Ness. She is a public health expert widely published on the connection between Tylenol use and neurodevelopmental disorders in children.

The Mota plaintiffs’ development could positively affect the separate multi-district litigations (MDLs) filed against Tylenol manufacturers. Depending on the result of Dr. Ness’s testimony in a Daubert hearing, the number of Tylenol Autism lawsuits could continue to grow and gain reliable traction.

There are currently 560 Tylenol autism lawsuits (including ADHD lawsuits) still pending in federal court. Lawyers are still accepting Tylenol lawsuits for state courts, but there might be a different angle for undecided claimants.

Pivoting to baby food may be another angle for parents of children with autism to build on their case. Connecting the link of certain brands of baby food to the development of autism is a different yet viable lawsuit they could pursue.

Why Are Victims Filing Tylenol Autism Lawsuits?

Victims are filing Tylenol autism lawsuits because they believe that exposure to Tylenol or acetaminophen products during pregnancy led to their children developing autism, ADHD, or other neurodevelopmental disorders. They assert that the manufacturers of these products failed to provide adequate warnings about these potential risks.

In these lawsuits, parents act as plaintiffs and claim that Tylenol’s manufacturers were negligent in not properly informing the public about the risks associated with taking Tylenol during pregnancy. This omission, they argue, has resulted in their children’s diagnosis of autism, ADHD, or other neurodevelopmental disorders. These claims are part of an ongoing class action acetaminophen autism lawsuit aimed at holding the manufacturers accountable for the alleged adverse effects their products have had on pregnant women and on children.

The Tylenol lawsuits have gained traction and continue to grow in number, particularly following legal proceedings where key decisions have favored the plaintiffs. For instance, courts have denied motions to dismiss these cases, thereby allowing them to proceed to the next stages of litigation. These favorable rulings have led to a surge in new filings as more parents who find themselves in similar situations join the class action lawsuit.

Health Implications of Tylenol

The primary health implication for filing a Tylenol lawsuit is the allegation that taking Tylenol or acetaminophen products during pregnancy may be linked to the child developing autism spectrum disorder, attention deficit hyperactivity disorder, or other neurodevelopmental disorders. Hence the question emerged in medical and parental communities: how much Tylenol causes autism? Plaintiffs argue that the manufacturers failed to warn about these potential risks adequately. Parents are seeking justice and compensation for the adverse health outcomes their children have experienced through a Tylenol lawsuit.

Known Injuries and Side Effects

Besides neurodevelopmental disorders, some of the other known side effects of using Tylenol include the following:

  • Liver damage: Acetaminophen, the active ingredient in Tylenol, is well known for its potential to cause liver damage if taken in excessive amounts.
  • Gastrointestinal issues: Some studies have linked acetaminophen use to an increased risk of gastrointestinal problems.
  • Increased risk of asthma: Some studies have suggested a potential link between acetaminophen use during pregnancy and an increased risk of the child developing asthma.

Eligibility for Victims and Legal Procedures

You may be eligible for the Tylenol autism lawsuit if you are a parent or guardian of a child who has been diagnosed with an autism spectrum disorder, ADHD, or another neurodevelopmental disorder, and you took Tylenol or acetaminophen products during pregnancy. The central claim must be that the child’s condition directly results from prenatal acetaminophen exposure and that the manufacturers failed to provide adequate warnings about such risks.

Am I Eligible to File a Tylenol Autism Lawsuit?

The first eligibility factor often centers around the timing and extent of Tylenol or acetaminophen usage during pregnancy. Documentation of the drug’s usage, such as pharmacy records or medical prescriptions, can be crucial in establishing a credible claim. If you used the drug as indicated but were not warned of its potential risks to your unborn child, this could strengthen your eligibility for the Tylenol lawsuit.

The second eligibility factor involves the child’s medical condition. A formal diagnosis of autism, ADHD, or another neurodevelopmental disorder from a qualified medical professional is typically required. Medical records detailing the child’s condition, treatments, and any associated medical expenses can also play a significant role in the lawsuit, both for eligibility and potential compensation.

Steps to File a Tylenol Autism Lawsuit

You can file a Tylenol lawsuit by following the steps below:

  1. Consult a lawyer: Contacting Tylenol autism lawyers can help in assessing the eligibility of your claim.
  2. Collect evidence: Gather all pertinent medical and pharmacy records and other documents supporting your case.
  3. File a complaint: Your attorney will draft and file a legal complaint against the responsible parties, outlining the allegations and demands.

Potential Compensation and Settlements

The average trial value of a successful verdict in a Tylenol autism case is estimated to be between $5 million and $10 million. This Tylenol compensation is intended to cover medical expenses, emotional distress, loss of quality of life, and other damages incurred due to the child’s condition.

Studies on Acetaminophen Usage and Safety

Recent medical studies have altered the way we view the safety of using Tylenol, or acetaminophen, especially during pregnancy. Growing scientific consensus now suggests that prenatal exposure to acetaminophen could be a contributing factor to the rising rates of autism and ADHD diagnoses.

In the September 2021 edition of Nature Reviews Endocrinology, a unified statement from 91 top medical professionals indicated that taking acetaminophen while pregnant could elevate the likelihood of a child developing autism.

This collective statement reviewed an expanding pool of research, both observational and animal-based, suggesting that acetaminophen exposure before birth might disrupt fetal development and contribute to neurodevelopmental issues such as autism. This compilation of research covered 29 observational studies and involved more than 220,000 parent-child duos globally.

The research consistently found a connection between substantial acetaminophen use during pregnancy and increased incidences of autism spectrum disorder. In particular, the studies revealed that prolonged usage of Tylenol during pregnancy could up the child’s risk for autism by 20%. This finding has been instrumental in giving rise to legal cases concerning acetaminophen and autism.

Moreover, the collected research also pointed out a direct relationship between the level of autism risk and the duration and dosage of acetaminophen consumed during pregnancy. Simply put, the more Tylenol taken during pregnancy, the higher the rates of autism observed.

The unified guidelines concluded by strongly advocating for preventative measures from both healthcare providers and public health institutions. One key recommendation was to place a warning label on all acetaminophen-containing products, cautioning against usage during pregnancy.

All Tylenol Autism Lawsuit Updates

February 2024

Judge Cota has granted permission for the Mota plaintiffs to present testimony from Dr. Roberta Ness, an epidemiologist and public health specialist with extensive publications on the link between Tylenol usage and neurodevelopmental disorders in children.

January 2024

Plaintiffs in an MDL face a February 1 deadline to justify why their cases shouldn’t be dismissed, impacting 501 plaintiffs with cases issued before January 11, 2024. Following Judge Cote’s ruling, which led to the dismissal of Tylenol autism lawsuits, plaintiffs are considering appeals and exploring state court options for compensation.

December 2023

Judge Cote’s ruling in the federal court dismissed all Tylenol autism lawsuits due to insufficient evidence linking prenatal Tylenol use to autism/ADHD. Following the pivotal Daubert hearing on December 7, 2023, this decision has led plaintiffs to focus on pursuing these cases in state courts.

November 2023

The Tylenol autism class action MDL has grown to 441 cases, with a critical Daubert hearing scheduled for December 7, 2023, in federal court. Concurrently, Tylenol autism cases are also advancing in state courts, notably in Madison County, Illinois, with key legal deadlines set for December 2023 and January 2024. The outcome of the Daubert hearing in federal court could significantly influence the trajectory of these lawsuits, potentially shifting the focus to state courts.

October 2023

The number of Tylenol autism lawsuits within the MDL has surged to 383, with a significant increase in new filings last month, leading up to the Daubert hearings, where expert testimonies will be scrutinized. The defense and plaintiffs have proposed different approaches for these hearings to Judge Cote, who has a history of favoring more efficient legal processes. Concurrently, recent research has shown that prenatal exposure to paracetamol, the active ingredient in Tylenol, might impact brain development by altering gene expression, potentially influencing litigation.

September 2023

Judge Cote had invited the FDA to weigh in on the appropriateness of the plaintiffs’ proposed warning labels for Tylenol and generic acetaminophen products earlier this year. The FDA was given until July 28th to respond but requested additional time, pushing the new deadline to September 15, 2023.

Interestingly, the FDA declined to submit a statement of interest, opting to stay neutral in the matter. This decision is considered a significant win for the plaintiffs, as an FDA recommendation against the warning could have led to the motion to dismiss on federal cases.

The absence of the FDA’s input keeps the acetaminophen autism lawsuits alive and allows them to proceed. Major legal events, including crucial Daubert motions, are expected in the coming month.

August 24, 2023

The fate of the Tylenol autism lawsuits hinges on the upcoming Daubert challenges, where Judge Cote will rule on the admissibility of the plaintiffs’ scientific evidence linking acetaminophen to autism. A favorable ruling for the plaintiffs could lead to settlements, while an unfavorable one would result in a motion to dismiss.

July 18, 2023

A record 64 new cases were added to the Tylenol autism MDL last month, bringing the total number of pending cases to 200. This surge suggests increased momentum, yet thousands of prospective plaintiffs remain cautious, awaiting the Daubert ruling.

June 1, 2023

Only six new cases were added to the Tylenol autism MDL this month, with many potential plaintiffs holding off. The hesitancy is attributed to concerns over the upcoming Daubert ruling, which could dismiss all federal cases if the scientific evidence used is deemed inadmissible.

May 22, 2023

The judge overseeing the Tylenol autism MDL dismissed failure-to-warn claims against retailers like CVS under Texas law but denied a similar motion under California law. This decision complicates the landscape for future cases, particularly those subject to Texas law.

April 21, 2023

Judge Cote denied J&J’s motion to dismiss based on federal preemption, holding that the company could have added warnings without violating federal rules. This follows a similar ruling against Walmart in November, bolstering the plaintiffs’ position in the lawsuits.

March 10, 2023

The Tylenol autism MDL in New York now has 107 pending cases, marking a growth of 37 cases since its inception four months ago. This indicates an accelerating trend in the litigation.
