Settlements for Tylenol Autism Lawsuits

Tylenol Autism Lawsuit Settlements: What to Know

Tylenol Linked to Autism

The makers of Tylenol and generic acetaminophen are facing product liability lawsuits alleging they negligently failed to warn pregnant women, doctors, and the public of the potential risk involved with using their products during pregnancy. Recent studies have tied the use of Tylenol during pregnancy to a greater incident rate and severity of autism spectrum disorder (ASD), ADHD (attention deficit hyperactivity disorder), complex developmental disorder, and other health issues. However, autism has been studied the most.

The Tylenol autism lawsuit is beginning to attract national attention. In this article, we will discuss lawsuits relating to the use of acetaminophen while pregnant, potential settlements relating to such lawsuits, and the science behind the link between Tylenol and autism, ADHD, and other neurodevelopmental disorders.

Skip to an important Tylenol Autism Lawsuit update.

Acetaminophen and Autism

In 2021, 91 American and European scientists (drafted by 13 and signed by an additional 78) were alarmed enough about the data illustrating a consistent association between acetaminophen and autism or ADHD, they signed a consensus statement urging pregnant women to minimize their use of acetaminophen during pregnancy. We will discuss this consensus statement and scientific evidence linking Tylenol to autism and ADHD later in this article. However, the science is becoming clear that using generic acetaminophen or Tylenol regularly during pregnancy poses a significant risk to the developing fetus.

Tylenol Autism Lawsuit Guide

Is There A Tylenol Lawsuit?

Tylenol lawyers reportedly spent over $1.7 million in mass tort advertising in October 2022, the third largest spend for any mass tort after mesothelioma (which does not really count, anyway) and Camp Lejeune. Yes. It is actually an ever-growing number of lawsuits that have been consolidated in the Southern District of New York before Judge Denise Cote it what is officially known: In Re: Acetaminophen – ASD/ADHD MDL No. 3043 Products Liability Litigation.

The “Tylenol autism lawsuit” encompasses all lawsuits filed in Federal Courts throughout the United States against both manufacturers and retailers of generic acetaminophen products and Tylenol.

We will discuss how the Tylenol autism lawsuit came to be, the present status of litigation, and what we can expect going forward.

Tylenol and Autism or ADHD Lawsuit Updates

Our goal is to update this page as often as possible. We will not only provide timely updates on the Tylenol autism ADHD lawsuit, our plan is to divulge any new scientific developments pertaining to the link between acetaminophen use during pregnancy and autism along with any coverage this issue earns in the mainstream media.

This will remain the most up-to-date page on the Tylenol autism class action.

January 15, 2023 - Update on Acetaminophen or Tylenol Autism Lawsuit

On Monday, January 9th, 2023, Judge Denise Cote, the presiding judge over the Tylenol multidistrict litigation, approved the proposed Short-Form Complaint for families filing Tylenol autism lawsuits. 

Short-Form Complaints are individually filed by new plaintiffs in a large-scale lawsuit as standardized abbreviations of a Master Complaint. A Master Complaint is filed on behalf of all plaintiffs involved in a lawsuit and provides broad coverage of the claims brought forward in the interest of plaintiff inclusivity. The purpose of these Short-Form Complaints is to give a uniform and more accessible format of claim to file for new plaintiffs which makes the process more efficient and manageable for the MDL.

The order by Judge Cote that approved these Short-Form Complaints additionally states that any plaintiff who has a case pending in the MDL must file a Short-Form Complaint by January 20, 2023. Plaintiffs seeking to file a Tylenol autism case in the future are to complete a short-form complaint within 14 days of bringing their case regardless of whether it was filed with the MDL or transferred from another district.

December 30, 2022 – Update on Acetaminophen Autism MDL

Judge Cote has provided both plaintiff and defense counsel until January 4, 2023, to file a proposed short-form complaint.  This will allow new plaintiffs a streamlined method to file new Tylenol autism lawsuits into this MDL. 

Additionally, counsel for the plaintiffs and defense could not agree on a joint discovery plan.  Judge Cote’s latest order makes a preliminary adoption of the defendant’s discovery plan.  However, she has requested that both parties work together to come up with a joint plan before the next status conference on January 4, 2023.

December 20, 2022 – Update on Acetaminophen Autism MDL

Judge Cote has recently proposed a quick deadline for plaintiffs to file two proposed master complaints with one being against the manufacturers of generic acetaminophen and Tylenol and the other against the retailers. Master short-form complaints are common in mass torts and allow new filings into the MDL by adhering to or agreeing to specific allegations in an abbreviated complaint. This will allow for a large number, of Tylenol lawsuits to enter the MDL in the coming months.

Judge Cote previously issued her order on December 4, 2022, creating a mechanism to allow for direct filings into the acetaminophen autism MDL. Judge Cote will conduct a telephone conference on January 6, 2022, wherein she is expected to determine the final version of the short-form complaint. Judge Cote has also ordered that all plaintiffs with a pending complaint in the MDL must submit a short-form complaint by January 20, 2022.

December 4, 2022 – Update on Tylenol Autism Lawsuit

Walmart (one of the many defendants in the acetaminophen autism MDL) has filed (filed on 11/28) a memorandum of law in support of its motion for reconsideration of Judge Denise Cote’s November 14th order denying their preemption defense and continues to claim that federal law preempts the plaintiff’s failure to warn arguments. In this case, Walmart is asking Judge Cote to either certify a request to the United States Court of Appeals for the Second Circuit (interlocutory appeal) or reconsider her denial of the preemption defense.

In turn, Judge Cote issued an Order providing plaintiffs until December 12, 2022, to file any pleadings in opposition to Walmart’s memorandum of law. This ruling is crucial to the future of the Tylenol pregnancy lawsuit. If the Second Circuit determines that federal law preempts plaintiffs’ claims, “such a decision would likely dispose of all claims inside the MDL (Walmart’s motion).” In other words, this could literally end the Tylenol autism lawsuit before it gets off the ground.

Keep in mind, it is highly unlikely Judge Cote will grant Walmart’s motion for reconsideration as there has been no change in the controlling law which is generally a basis for granting such. Further, we do not believe Judge Cote will certify an interlocutory appeal at this stage. Rather, we see the Second Circuit entertaining this appeal maybe two to three years down the road assuming plaintiffs get past Daubert hearings (hearing conducted by the trial Judge to determine whether an expert’s testimony and science are admissible), motions for summary judgment and likely multiple bellwether trials.

November 30, 2022 – Update on Tylenol Autism Lawsuit

A joint letter prepared by counsel for the plaintiffs and defendants discussing the status of a census order and an agreement that both sides will update Judge Cote by December 23, 2022, as to any process. In a separate filing, both parties sent an agreed-upon list of potential special masters to serve as a mediator in any settlement discussions in Tylenol autism cases.

November 23, 2022 – Update on Acetaminophen Autism Lawsuit MDL

Four separate lawsuits have been filed into the MDL naming Johnson & Johnson as a defendant. There was much speculation on why the vast majority of lawsuits were against retailers and not manufacturers. We believe this will open the floodgate of lawsuits against Johnson & Johnson (parent company of the manufacturer of Tylenol) and the manufacturers of generic acetaminophen products. The argument will be based on Johnson & Johnson’s failure to warn of the potential dangers of using acetaminophen during pregnancy.

“Johnson & Johnson Tylenol Lawsuit”

An interesting tidbit is we are now seeing commercials in which the narrator refers to this litigation as “The Johnson & Johnson Tylenol Lawsuit.” This is very similar to the marketing behind the talc powder ovarian cancer lawsuits.

November 19, 2022 – Update on Acetaminophen Autism Lawsuit MDL

Judge Denise Cote held her initial status conference in what is nationally referred to as the Tylenol Autism lawsuit. In fact, Judge Cote appointed leadership in this emerging multidistrict litigation involving lawsuits alleging acetaminophen use during pregnancy causes autism or attention deficit hyperactivity disorder in children.

Attorneys Mark Lanier of The Lanier Law Firm, Mikel Watts of Watts Guerra, and Ashley Keller of Keller Postman will serve as lead plaintiffs’ counsel and are also members of the plaintiff’s executive committee along with five other lawyers; Zoe Littlepage of Littlepage Booth, Eric Holland, Holland Law Firm, Roger Smith, Beasley Allen, Sean Tracey, Tracey Fox King & Walters, and Ashley Barriere, Keller Postman. Judge Cote also listed ten members of the Tylenol autism class action lawsuit plaintiff’s steering committee.

We have noted significant media attention directed at the Tylenol autism ADHD lawsuit as well as dangers related to the consumption of acetaminophen during pregnancy. USA Today published an article discussing the increased risk posed by Tylenol use during pregnancy, on November 9, 2022, which was widely shared on social media.

The USA Today article quoted Roberta Ness, an epidemiologist (former Dean of the University of Texas School for Public Health) who served as an expert witness in the talc powder causing ovarian cancer lawsuits. Ness states she believes acetaminophen is a cause of both autism and ADHD. “This is a very big for an epidemiologist to say.” Further, she stated her belief that 1 in 7 children who developed autism may have avoided such diagnoses if the mother had avoided using acetaminophen during pregnancy. A baby’s in-utero exposure to acetaminophen is the issue. In this very article, Ness estimates that 20% of children diagnosed with either autism or ADHD have in-utero exposure to high levels of acetaminophen.

We have seen a strong uptick in television advertisements for the Tylenol autism and Tylenol ADHD lawsuit. Further, more mainstream press is discussing the Tylenol autism and Tylenol ADHD link and more scientific evidence relating the use of acetaminophen during pregnancy to the diagnosis of a neurodevelopmental disorder.

November 14, 2022 – Update on Acetaminophen Autism Lawsuit MDL

Judge Denise Cote ruled against Walmart’s motion to dismiss and more importantly flatly rejected the defendant’s preemption argument. Preemption is a common argument utilized by defendant manufacturers and retailers in pharmaceutical mass tort litigation. In utilizing the preemption defense. the defendant argues that any state law cause of action is preempted by the Federal Drug Administration (FDA) which has complete control over the labeling of any drug or device.

Preemption is governed by precedent law established in the U.S. Supreme Court case of Merck v. Albrecht. In Merck, the Supreme Court ruled that preemption is ultimately a question of law and must be decided by a judge, not a jury. Another important ruling in Merck is a defendant can prevail only if they establish the provided full justification to the FDA of a need for a label change and the FDA informed the defendant they would not approve the labeling change.

Judge Cote Issues Order Denying Walmart’s Preemption Defense

Judge Cote’s decision will now impact all acetaminophen autism lawsuits pending in the Southern District of New York. In her order, Judge Cote analyzed two cases that comprise the defendant’s motion to dismiss and assertion of the preemption defense; Hatfield et al. v. Wal-Mart Stores, Inc., 22cv9011, and Roberts et al. v. Wal-Mart Stores, Inc., 22cv9012.

In both cases, pregnant women took Equate brand Tylenol. Equate is Walmart’s over-the-counter equivalent acetaminophen brand. Equate brand Acetaminophen products are only sold at Walmart.

In turn, both mothers now allege their children have been diagnosed with both autism and ADHD due to acetaminophen use during pregnancy. Further, the plaintiffs allege that Walmart violated State law by failing to warn of the elevated risks of dangers associated with prenatal acetaminophen exposure.

In her ruling, Judge Cote, stated, that “a manufacturer is responsible for the adequacy of the warnings on its drug label. The regulation of acetaminophen generally and the Pregnancy Warning regulation, in particular, do not alter that responsibility.” 

This is a huge victory for all plaintiffs and for the overall acetaminophen or Tylenol autism lawsuit. Acetaminophen autism ADHD lawsuits are no longer subject to a preemption defense by any manufacturer or retailer of generic acetaminophen products.

November 13, 2022 – Update on Tylenol Autism Lawsuits

The initial status conference on acetaminophen autism ADHD lawsuits is scheduled for November 17, 2022. All acetaminophen lawsuits have been consolidated before Judge Denise Cote in United States District Court for the Southern District of New York. We anticipate Judge Cote will assign leadership for plaintiffs and defendants. More specifically, Judge Cote will likely appoint lead counsel, liaison counsel, and members of the plaintiff’s steering committee for Tylenol autism lawsuits.

We will update you tomorrow on another recent development. Judge Cote just issued an order that rules against Walmart (one of the defendants) on the issue of preemption and applicable FDA labeling laws.

November 9, 2022 – Update on Tylenol Autism Lawsuits

Advertising targeting women who used acetaminophen during pregnancy for the Tylenol autism class action has increased exponentially over the past month. We are noting an increase in television commercials over more channels and a growing number of pay-per-click advertisements targeting women interested in the Tylenol autism ADHD lawsuit.

November 2, 2022 – Update on Tylenol Autism Class Action Lawsuit

One sign of how big the Tylenol autism lawsuit could potentially be, is the amount of advertising on both television and radio. The media is beginning to investigate whether Tylenol causes autism. Just this evening, I counted four commercials concerning acetaminophen lawsuits. The Tylenol autism class action is just starting to take off.

October 26, 2022 – Update on Acetaminophen Autism Lawsuit MDL

Acetaminophen autism MDL Judge Denise Cote issued another order on October 24, 2022, shedding additional light on requirements for the initial status conference that she announced in her October 18th order. The most recent order states that a notice of intent to appear at the initial status conference must be filed by November 10, 2022. Further, Judge Cote has requested that plaintiffs’ counsel file a joint letter by November 3, 2022, spelling out a proposed structure for all leadership positions on the acetaminophen autism MDL; including both lead and liaison counsel as well as all members of plaintiffs’ steering committee.

The initial status conference for the Tylenol lawsuit MD in the Southern District of New York is set for November 17, 2022. 

Vying for Leadership in The Tylenol Autism Lawsuit

Applications for leadership positions are due on November 14, 2022, and objections to such applications are due by November 16, 2022. We anticipate hundreds of acetaminophen autism lawsuits will be filed into the MDL before the end of 2022.

The future of the Tylenol class action lawsuit hinges on establishing causation. There will be strict scientific criteria that plaintiff lawyers must meet. This will largely depend on whether the Court feels the most recent scientific studies shows a dose-dependent link between prenatal acetaminophen exposure and the incidence of autism spectrum disorder diagnosis and the severity of such. The strength of each individual Tylenol lawsuit will depend on the amount of acetaminophen used and the severity of the child’s diagnosis of autism or ADHD.

October 5, 2022 – Update on Acetaminophen or Tylenol Autism Lawsuit


Approximately 90 acetaminophen autism lawsuits will be transferred and consolidated before the Honorable Judge Denise L. Cote (transfer order from JPML on acetaminophen autism lawsuits) in the Southern District of New York. Judge Cote was nominated to the bench by President Bill Clinton and confirmed by the U.S. Senate in August of 1984.

We believe hundreds of Tylenol Autism Lawsuits will be filed over the coming months alleging Tylenol/acetaminophen exposure in pregnant women greatly increased autism spectrum diagnosis in their children. It is possible that over 1000 acetaminophen autism lawsuits could be filed before the end of 2022 in the Southern District of New York.

September 20, 2022 -Update on Acetaminophen or Tylenol Autism Lawsuit

On September 29, 2022 (nine days away), the Joint Panel on Multidistrict Litigation (JPML) will hear the plaintiff’s motion to consolidate all acetaminophen that has been filed in Federal Court into a single MDL (multidistrict litigation). The purpose of an MDL is to consolidate all cases before a single Judge to promote consistency in discovery, streamline all litigation and increase the odds of a global settlement.

Tylenol Linked to Autism – Tylenol Autism Claim

If you believe that you or your child have been exposed to significant amounts of Tylenol or generic acetaminophen in utero and presents with Autism Spectrum Disorder or ADHD, you may have a product liability claim against the manufacturers of generic acetaminophen (Mallinckrodt) or Tylenol (McNeil Consumer Products Co., a wholly-owned subsidiary of Johnson & Johnson). However, we are also investigating claims and potential Tylenol and/or acetaminophen lawsuits against retailers such as CVS, Walgreens, Costco, and Walmart.

These claims are often resolved through an out-of-court settlement. However, the amounts available through this legal avenue vary depending on many factors. The amount of fetal exposure to acetaminophen coupled with your child’s clinical presentation and diagnosis will play a large role in determining value. Recent studies indicate that in-utero acetaminophen exposure can impact fetal brain development.

The Tylenol Autism Lawsuit

We urge you to contact a Tylenol autism lawyer at Dolman Law Group to learn about how much your potential Tylenol autism settlement might be worth and the strength of your case.

The Tylenol autism lawsuit is one of the fastest-growing mass tort lawsuits in the project. We will discuss the mechanism of mass tort litigation later in this article. However, all Tylenol autism cases throughout the nation are being consolidated in the United States District Court for the Southern District of New York. We believe there will be over 1000 Tylenol autism cases filed in the Southern District by February.

Mass tort lawyers reported spending over $1.7 million in Tylenol lawsuit advertising just in October of 2022, which is the third largest expenditure for any mass tort after mesothelioma and Camp Lejeune. We urge you to contact a Tylenol autism lawyer at Dolman Law Group to learn about how much your potential Tylenol autism settlement might be worth and the strength of your case. Our Tylenol attorneys are able to investigate your claim immediately.

If your child has been diagnosed with autism spectrum disorder and you used acetaminophen during pregnancy, we want to speak to you right away. Tylenol use during pregnancy or prenatal exposure to generic acetaminophen has been scientifically linked to several neurological disorders based on studies we will discuss below. The dangers of using Tylenol during pregnancy can no longer be ignored.

JPML Hearing to Determine Venue for Tylenol Autism Lawsuit

The plaintiffs are seeking for the venue in the Tylenol autism lawsuit to be placed in the Northern District of California or the Eastern District of New York. In turn, the defendants are opposing the creation of a Tylenol autism MDL. However, in the event the JPML creates an MDL, they are pushing for the venue to be in the Districts of New Jersey which is seen as a less plaintiff-friendly jurisdiction.

The defendants are opposing the creation of an MDL on the grounds that all lawsuits thus far have been filed against retailers (CVS, Walgreens, Costco, etc…) and not against manufacturers of generic acetaminophen and Tylenol. Further, the defendants contend that not enough lawsuits have been filed. This is a farce as a Tylenol autism MDL has the potential to be one of the largest mass torts in U.S. history. We believe there will be over 1000 Tylenol autism lawsuits filed over the next few months.

How Much Can I Recover in a Tylenol While Pregnant Autism Lawsuit?

What Will be the Average Tylenol Autism Lawsuit Settlement

While it is too early to determine the full settlement value of a Tylenol acetaminophen autism lawsuit, we can certainly speculate and estimate based on prior mass tort projects. Before rendering our estimates, keep in mind that it is too early to determine how strong the scientific evidence in this MDL will be and the amount of fetal exposure to acetaminophen.

The consensus among the plaintiff trial lawyers is we are dealing with strong science behind an ever-growing body of published studies linking autism spectrum disorder to acetaminophen or Tylenol use during pregnancy. However, it will be some time before we know whether the science concerning whether acetaminophen impacts fetal development and contributes to developmental disorders is strong enough to reach a jury trial. However, based on the scientific research conducted as of date, we feel confident in the Tylenol lawsuits that have been filed and will continue to be filed over the next few years.

Keep in mind that in a civil case, our burden is not “absolute certainty.” Rather, we must establish that the use of generic acetaminophen or Tylenol during pregnancy makes it more likely than not that the baby will be subsequently diagnosed with autism or ADHD.

An example provided to me by fellow attorney Patrick Luff concerns tobacco litigation as an analogy to the Tylenol autism litigation.

“Take, for example, the 40-year-old smoker who develops lung cancer. You cannot say with absolute certainty smoking caused his lung cancer. However, you can say that is probable that smoking caused his cancer.”

In this case, we simply must demonstrate that using acetaminophen or Tylenol during pregnancy more likely than not contributed to the diagnosis of autism or ADHD.

Early Projections for Tylenol Autism Settlement Amounts

We believe settlements will be based on the severity of the autism spectrum disorder diagnosis (ASD). Level three (ASD level 3) autism cases will have the most significant value and those with a level one autism diagnosis will have the lowest value.

We must establish through scientific research and evidence that the use of acetaminophen during pregnancy established an increased risk of a child being subsequently diagnosed with a developmental disorder.

We base our Tylenol autism settlement projections on our assumption the science is strong enough to survive scientific hearings (Daubert hearings). We project the average jury verdict could be in excess of $2 million for individuals with an autism diagnosis who manifest the more significant autism spectrum symptoms in their most severe form. Please note that the severity of autism is measured in three different grades. ASD level 1 is the least severe and ASD level 3 is the most severe form of autism spectrum disorder.

Projected Tylenol Autism Lawsuit Settlement Amounts

The majority of Tylenol lawsuits will never reach trial. In fact, very few mass tort cases are selected by Court for a bellwether trial. Thus, the vast majority of these claims will eventually settle.

Our very early projection for settlement value is:

  • $50,000.00 to $225,000.00 for ASD level 1 claims
  • $250,000.00-$500,000.00 for ASD level 2 claims
  • and in excess of $500,000.00 for ASD level 3 claims

Symptoms of Autism Spectrum disorder (ASD)

Keep in mind these are simply early settlement projections for the Tylenol class action lawsuit. We based these projections partly on costs related to support and treatment that will be required over a lifetime for a child with level 3 autism. The main factors are the severity of autism spectrum disorder or ADHD and the amount of acetaminophen the mother used while pregnant.

The most common symptoms of autism spectrum disorder are:

  • Delayed speech and ability to communicate
  • The avoidance of eye contact
  • Disproportionate or unexpected reactions to sounds, smell, touch, and taste (sensory processing difficulties)
  • Minor changes to routine cause high levels of stress
  • Very adherent to routines and rules
  • Inability to understand social cues

Autism Spectrum Disorder Level 1: $50,000 – $225,000 Range

Level 1 is the mildest form of autism. It is often referred to as “high-functioning autism,” and is defined as a child who often speaks in complete sentences but has difficulty understanding social cues. Further, a child with level 1 autism may experience difficulty engaging in conversation and will often have difficulty with organizational and planning skills. Another hallmark of level one autism is difficulty in moving from one task to the next. We believe children diagnosed with attention deficit hyperactivity disorder (ADHD) would fall into a similar range as those with level 1 autism.

Autism Spectrum Disorder Level 2: $225,000 – $500,000 Range

Children with level 2 autism have more obvious communication (both verbal and non-verbal) issues. Another hallmark of level 2 autism spectrum disorder, is engaging in repetitive behavior. Additionally, children with level 2 autism have significant difficulty with changes in routine and coping with deviating from such.

Autism Spectrum Disorder Level 3: $500,000+

Children with level 3 autism face many of the same challenges and issues those with level 1 and level 2 have. However, these similar traits are much more severe in level 3. Level 3 children will often be non-verbal or make use of just a few select words. Further, they will have extreme difficulties in coping with changes to routines. Those with level 3 autism may only seek social contact to meet their immediate needs.

Keep in mind these classifications are not rigid. Every Tylenol autism lawsuit will be valued differently based on not only the classification of autism spectrum disorders but the extent of exposure to generic acetaminophen or Tylenol, along with confounding factors involving both parents or the child in question.

Does Tylenol Cause Autism? – “Tylenol Causes Autism”

We do NOT believe Tylenol is the primary cause of autism. In fact, autism has a heavy genetic component. Rather, we strongly believe that the use of acetaminophen during pregnancy—and more specifically, in utero exposure to acetaminophen—greatly increases the probability of a child being subsequently diagnosed with autism or ADHD. Autism,

ADHD and other neurodevelopmental disorders predate acetaminophen. However, we subscribe to the growing body of science that demonstrates a causal link between in-utero exposure to acetaminophen and a diagnosis of autism spectrum disorder in the child that was exposed.

Genetics are known to play a very large role in autism and ADHD. Environmental factors do lead to a greater rate of incidence and there are numerous studies that indicate not only an association between the use of acetaminophen and the incidence of autism; but a dose-dependent relationship. In other words, the greater the level of acetaminophen the higher the incidence rate and severity of autism and ADHD.

Tylenol has long been marketed as a safe over-the-counter drug for pregnant women to utilize as a pain reliever. Recent studies analyzing umbilical cord blood samples illustrated a dose-dependent relationship between acetaminophen and autism. Study after study demonstrates a consistent association between acetaminophen and autism. The vast number of studies all conclude that Tylenol use while pregnant leads to elevated risks of autism and negative neurodevelopmental outcomes for the developing fetus..

It is important to note that Autism rates began to literally explode in the 1980s after Tylenol replaced aspirin for routine use due to public fear of Reyes Syndrome. It is also important to draw a delineation between those who believe vaccinations cause autism vs. in utero exposure to acetaminophen. The vaccination autism link has been debunked time and again. The very scientist who initially stated the link has been completely discredited. The science behind whether Tylenol causes autism is significant.

Tylenol Usage During Pregnancy Connected to Neurodevelopment Disorders Like Autism and ADHD

Tylenol is a common over-the-counter drug used to treat pain and reduce fever. We all know that acetaminophen relieves pain. Unfortunately, in some cases, it may be doing more harm than good and health risks can no longer be ignored.

Acetaminophen Use During Pregnancy

More than 65% of pregnant women in the U.S. turn to acetaminophen as their pain reliever choice during pregnancy. Pregnant women have been told by health professionals and more specifically Obstetricians, that of all the over-the-counter medications out there, acetaminophen was safe for consumption. In 2021, a consensus statement on acetaminophen use during pregnancy was issued by 91 scientists, researchers, and physicians, wherein health professionals warned against acetaminophen use during pregnancy unless it is medically necessary. They caution pregnant women that a growing body of research indicates acetaminophen use may alter fetal brain development and result in neurodevelopmental disorders. More specifically, they warn of using Tylenol regularly during pregnancy.

Johns Hopkins University Boston Birth Cohort Study (2020)

Based on emerging research on acetaminophen conducted by both Yale University and Johns Hopkins University, there is a link between mothers who took Tylenol during their pregnancies and the occurrence of neurodivergent conditions, such as autism, in their children. There now exists multiple studies (analysis of multiple studies on acetaminophen use during pregnancy) illustrating a potential causal link between higher rates of autism and acetaminophen use during pregnancy. More specifically, the cord blood samples analyzed in the Johns Hopkins study (discussed below) demonstrate a dose-dependent relationship between Tylenol and autism based on in-utero exposure to acetaminophen. Further acetaminophen use during pregnancy is among the risk factors for a host of other developmental disorders and increases a child’s risk for ADHD.

Acetaminophen use During Pregnancy Causally Linked to Autism?

What makes the Johns Hopkins University study significant (published in Jama Psychiatry), is the illustration of a dose-dependent relationship between Tylenol or generic acetaminophen use during pregnancy and a subsequent diagnosis of autism or ADHD.  The Johns Hopkins study sheds light on how acetaminophen impacts child development via the presence of such in umbilical cord blood samples

What makes the Johns Hopkins University study significant, is the illustration of a dose-dependent relationship between Tylenol or generic acetaminophen use during pregnancy and a subsequent diagnosis of autism or ADHD.  The Johns Hopkins study sheds light on how acetaminophen impacts child development via the presence of such in umbilical cord blood samples.

Cord Blood Samples Measured For Acetaminophen

Researchers evaluated umbilical cord blood samples and noted those with a higher concentration of acetaminophen exposure showed a dose-dependent greater incidence of autism. This displayed a quasi-causal link at a minimum between acetaminophen use during pregnancy and developmental disorders. In fact, babies whose cord blood samples contained the highest amounts of acetaminophen were approximately three times more likely to be diagnosed with autism or ADHD.

The higher the concentrations of acetaminophen in umbilical cord blood samples, the greater the incidence of autism spectrum disorder and ADHD. Cord plasma biomarkers of in-utero fetal exposure to acetaminophen use contained increased risk indicators for ADHD and autism and were consistent among mother-child pairs.

Acetaminophen has a short half-life (amount of time it remains active in the bloodstream). The fact that cord blood samples contained different amounts of acetaminophen tells us little about whether the use of this over-the-counter drug is dangerous in earlier periods of pregnancy (first or second trimester). However, there is no scientific evidence that the greater the use of acetaminophen during pregnancy the greater the risk of neurodevelopmental disorders.

Danish National Birth Cohort Study (2015)

In the Danish National Birth Cohort Study, 64,322 mother-child pairs were analyzed to study the causes of diseases in children and complications sustained by the mother during birth. A number of factors and health conditions were analyzed. The researchers noted an association between prenatal use of acetaminophen and a diagnosis of ADHD.

International Journal of Epidemiology (2016)

In 2016, the International Journal of Epidemiology published a study (research paper anlyzing data from Spanish birth cohort) entitled Acetaminophen use in pregnancy and neurodevelopment: attention function and autism spectrum symptoms. The authors analyzed a Spanish birth cohort of 2644 mother-child pairs to determine whether prenatal exposure to acetaminophen resulted in adverse neurodevelopmental conditions at age 1 and age 5. The authors concluded that prenatal acetaminophen exposure was associated with a higher rate of autism spectrum disorder symptoms in males and ADHD symptoms in both sexes.

European Journal of Epidemiology (2021)

The European Journal of Epidemiology (published study analyzing data from Danish Birth Cohort study) published a study wherein researchers analyzed all the data collected from the 2015 Danish Birth Cohort study. Researchers determined that in-utero acetaminophen exposure was associated with adverse neurodevelopmental conditions such as a clear increase in a child’s risk for autism and ADHD.

Prenatal Exposure To Acetaminophen Linked To ASD & ADHD

Tylenol ADHD Lawsuit

A study published in the American Academy of Pediatrics showed that even moderate use of acetaminophen during pregnancy created an increased risk for attention deficit hyperactivity disorder. It is important to note that Tylenol use during pregnancy was linked to ADHD in every Tylenol autism study. In fact, the link between Tylenol and ADHD slightly outpaces the incident rate of Tylenol and autism in study after study. We are presently handling a large number of Tylenol ADHD claims. We anticipate our legal team will file numerous Tylenol ADHD lawsuits over the coming months.

Medical Community Takes Note of Tylenol Autism Link

It took far too long for health professionals to take notice. The Tylenol autism lawsuit will only serve to draw more attention to an emerging body of research that establishes acetaminophen use during pregnancy is among the risk factors for adverse neurodevelopmental outcomes.

Autism and Tylenol Use During Pregnancy

A 2021 consensus statement (referenced in the third paragraph of this article) penned by multiple medical experts published in Nature Reviews Endocrinology warned pregnant women that the use of acetaminophen during pregnancy could spike the rates of autism.

In fact, the authors say in the abstract section that “increasing experimental and epidemiological research suggests that prenatal exposure to APAP (Acetaminophen) might alter fetal development, which could increase the risks of some neurodevelopmental, reproductive, and urogenital disorders.”

Based on the new research and existing body of prior scientific evidence these experts recommend women avoid taking acetaminophen during pregnancy.

A strong causal link via scientific evidence suggests the use of acetaminophen during pregnancy creates a higher risk of the possibility your child will present with or obtain a diagnosis of autism spectrum disorder or ADHD. This discovery has led many families to pursue legal action against the makers of these medical products and the retailers who have earned substantial profits selling these over-the-counter medications without warning of the potential health risk. This is the causal link that must be proven for the Tylenol lawsuit to be successful.

2017 Study Indicates how Acetaminophen Injures the Fetal Brain

The Journal of International Medical Research published a study (how Tylenol impacts fetal brain development), that discussed the likely mechanism, for how generic acetaminophen and Tylenol caused autism by impacting fetal brain development.

Scientists believe it may inhibit essential enzymes in brain development like the Cox-2 enzyme. Further, it is also believed to alter or interfere with the firing rate of neurons in the hypothalamus.

There is also believed to be a causal link between the use of acetaminophen and inflammatory diseases. This tells scientists that acetaminophen use during pregnancy may result in inflammation of the brain.

Tylenol Pregnancy Lawsuit

At no point have the manufacturers of Tylenol or generic medication offered a disclaimer to pregnant mothers of existing indications (medical literature and clinical studies) acetaminophen exposure in utero creates a higher risk your unborn child may develop autism spectrum disorder. Tylenol lawsuits are alleging that manufacturers and retailers knew of the growing body of scientific research and failed to provide any warning whatsoever. There have been a number of published studies now indicating Tylenol use during pregnancy is causally related to ADHD diagnosis, autism spectrum disorders, and other health risks.

Tylenol and manufacturers of generic acetaminophen are now being accused of promoting their products as safe pain-relief alternatives during pregnancy, when in fact they may be responsible for causing neurological damage to babies in utero. Health professionals warn of the potential link between Tylenol and autism. The health issues or conditions that may be correlated with significant or prolonged prenatal acetaminophen exposure or Tylenol usage during pregnancy include:

Health Issues Associated With Tylenol Usage Can Have a Significant Cost

While these conditions are not life-threatening, some of these issues can significantly impact a person's quality of life and ability to learn, develop social skills, and work. Parents may endure extreme stress while pursuing care for their children impacted by these issues. Additionally, there is often an economic cost for parents of children with these health concerns, especially neurological disorders.

For example, a child with ASD may require therapy, medication, and additional tutoring. In some cases, they may require life-long care. Parents may be forced to miss work to take their children for treatment, forfeit job opportunities to care for their children, or substantially reduce their standard of living to afford treatment.

Costs like these may be eligible for compensation if we can establish acetaminophen exposure during pregnancy that resulted in a diagnosis of autism or attention deficit hyperactivity disorder (ADHD).

Is There a Lawsuit Against Tylenol for Autism or a Tylenol Class Action Lawsuit?

Yes and no. There are a number of lawsuits filed against the retailers who sell acetaminophen or Tylenol but none of the lawsuits filed in Federal Court have named the manufacturers of Tylenol or generic acetaminophen as defendants. This is likely done as part of an overall strategy as retailers are less likely to want to litigate such cases while being subjected to awful publicity. Drug manufacturers are more inclined to defend the Tylenol autism lawsuits aggressively.

Tylenol ADHD Lawsuit

A 2014 study published by the Journal of the American Medical Association involved 64,322 mother-child pairs and found that children with prenatal exposure to acetaminophen showed close to a 30% increase in developmental disorders such as an ADHD (attention deficit hyperactivity diagnosis) diagnosis.

While the Tylenol autism link has received some media attention of late, we have seen very little attention focused on ADHD diagnosis linked to acetaminophen. The aforementioned 2014 study demonstrated that acetaminophen crosses the placental barrier. Further, the study also found that using acetaminophen in more than one trimester created a greater incidence rate of ADHD or increased the child’s risk of other developmental disorders.

A 2021 study published by the European Journal of Epidemiology, found in utero acetaminophen exposure was 21% more likely to be diagnosed with ADHD. There is a growing body of scientific and epidemiological studies that the use of acetaminophen impacts fetal brain development. It is theorized that acetaminophen disrupts neurodevelopment and in turn child development.

We believe the science linking Tylenol to ADHD is very strong and shows a dose-dependent causal relationship.

The Tylenol Autism Class Action Lawsuit Process in a Multidistrict Context

The product liability claims against Tylenol and other makers of acetaminophen are in the process of being consolidated into a multi-district litigation class action lawsuit. This means all Tylenol lawsuits would be heard in one jurisdiction even if the plaintiffs are located across the U.S. to consolidate court resources. It also allows plaintiffs to share the burden of expenses like court fees.

Tylenol autism lawyers for injured parties must convince a jury that manufacturers like Johnson & Johnson breached their duty of care to consumers by failing to warn them of the risks associated with acetaminophen. We believe manufacturers and retailers were both negligent by ignoring a growing body of scientific evidence illustrating acetaminophen use during pregnancy increases the risk for autism spectrum disorders. Failure to warn is at the heart of the Tylenol pregnancy lawsuit.

Our law firm can assist in accurately calculating the value of your damages in order to make a claim for compensation against acetaminophen or Tylenol drug makers like Mallinckrodt or Johnson and Johnson.
