For decades, doctors have prescribed Tylenol (acetaminophen) to pregnant women for fever reduction and pain relief. However, Recent reports have raised alarms over possible links between Tylenol use and an elevated risk of developmental health conditions, like autism spectrum disorder.
In September 2025, the United States Food and Drug Administration (FDA) initiated a label change for Tylenol warning labels to reflect evidence linking Tylenol use by pregnant women to an increased risk of neurological issues like attention-deficit/hyperactivity disorder (ADHD) and autism in children. Plaintiffs proposed warning labels to inform pregnant women of these potential risks, and the agency issued a letter alerting doctors nationwide.
However, the agency notes that while there has been an association between neurodevelopmental conditions and acetaminophen cited in many scientific studies, some studies suggest that prenatal Tylenol use may increase a child’s risk of autism and ADHD.
Despite these findings, a causal relationship between prenatal acetaminophen use and autism has not been definitively proven, and there are contradicting studies in the scientific sphere.
It’s essential to note that Tylenol (acetaminophen) is the only over-the-counter medication approved to treat fevers during pregnancy–high fevers in pregnant mothers may endanger the lives of unborn children.
There is also ongoing debate within the global medical community regarding the safety of acetaminophen during pregnancy.
As a result of the above concerns, families across the country are filing Tylenol autism lawsuits against manufacturers and sellers of the drug. Suppose your child developed autism or any other neurological condition related to prenatal Tylenol exposure. In that case, you may be entitled to financial compensation to cover your medical bills, lost wages, and emotional and physical suffering.
Understanding the Tylenol Autism Lawsuit: What You Need to Know
Recently, hundreds of Tylenol autism lawsuits have emerged against Johnson & Johnson, the maker of the medication, and major retailers that sell acetaminophen generics. There have been numerous lawsuits filed claiming that Tylenol use during pregnancy may cause autism spectrum disorders and ADHD. These prenatal Tylenol lawsuits claim that the use of Tylenol during pregnancy might increase the risk of autism in kids.
Hundreds of plaintiffs across the country have filed Tylenol ADHD lawsuits, shedding light on the potential link between Tylenol and neurological conditions, like autism spectrum disorder and ADHD. Plaintiffs filed acetaminophen lawsuits against major manufacturers and retailers.
These cases argue that Johnson & Johnson, the manufacturer of acetaminophen and generic equivalents, didn’t adequately warn the public about the potential dangers linked with Tylenol use during pregnancy.
Advocacy groups and parents have voiced concerns, quoting studies that demonstrate a correlation between Tylenol exposure during pregnancy and an elevated risk of neurodevelopmental disorders in kids.
These lawsuits aim to hold manufacturers responsible for allegedly not sharing this information with the public. The broader context of acetaminophen lawsuits includes a growing number of lawsuits filed in both federal and state courts.
The claims against Johnson & Johnson focus on their failure to inform the public about the potential dangers of Tylenol use during pregnancy. The ongoing Tylenol pregnancy lawsuit centers on the alleged failure to warn pregnant women about the risks of acetaminophen, including autism spectrum disorders and ADHD in children.
Claimants argue that the manufacturers should have given clear and adequate warnings on marketing materials and product labels concerning the possible correlation between Tylenol and the development of autism and ADHD in children.
Although acetaminophen autism claims are still ongoing and outcomes remain uncertain, these lawsuits have increased awareness about the need for transparency and further research concerning the use of Tylenol during pregnancy.
Recent Legal Developments in the Tylenol Autism Case
As of October 27, 2025, the Tylenol ADHD and autism lawsuits progress in one of the most-watched pharmaceutical litigation cases in the country. Complainants claim that prenatal acetaminophen exposure increases the risk of a child diagnosed with ADHD and a child’s autism, and that retailers and manufacturers didn’t adequately warn the public of those potential dangers. Over the counter drugs like Tylenol are at the center of these acetaminophen lawsuit claims, with major law firms and plaintiffs lawyers coordinating the litigation in both federal and state courts.
Important developments include:
- On October 1, 2025, courts re-examined the connection between acetaminophen and autism. A recent report in the Wall Street Journal indicates the United States Department of Health and Human Services (HHS) is gearing up to release a report demonstrating a potential association between prenatal acetaminophen exposure and autism. The FDA has also initiated the process for changing the warning label and is advising medical professionals about the possible link between prenatal acetaminophen exposure and subsequent autism diagnoses. This stunning news comes at a pivotal point, as the Second U.S. Circuit Court of Appeals is set to hear oral arguments on November 17, 2025, which could determine whether Tylenol autism claims are revived. The appellate brief submitted by plaintiffs argues that Judge Cote’s ruling improperly excluded expert testimony and misapplied the Daubert standard. The Tylenol autism litigation had stalled since Honorable Judge Denise Cote struck out the complainants’ expert witness in 2023 and later made a summary judgment in 2024, and denied motions to reconsider; her denial of these motions led to the current appeal. However, the upcoming appeal, together with the anticipated FDA action and HHS report, has reignited hope for parents seeking justice, and an interlocutory appeal or immediate appeal could further expedite or delay proceedings.
- The combined Acetaminophen – Autism/ADHD Products Liability Litigation, No. 3043 in the Southern District of New York, is known as the Tylenol autism MDL and is a multi district litigation pending in federal court. It currently has more than 500 active lawsuits, with additional legal claims expected as scientific research continues to raise public awareness. District Judge Denise Cote is presiding over the federal litigation.
- Complainants’ allegations focus on evidence suggesting that repeated or prolonged prenatal use of Tylenol may affect fetal brain development. They claim that Johnson & Johnson, Walmart, and others didn’t update product labels or offer adequate safety warnings to pregnant women.
- In 2024, courts dismissed some generic labelling allegations under federal law and preemption regulations, but allowed key negligence and failure-to-warn allegations to proceed into the discovery stage. Some motions to dismiss filed by defendants were based on federal law and preemption, and claims lack legal merit was a key argument.
- Throughout 2025, the discovery process has focused on gathering scientific evidence and expert testimony. Defendants objected to certain expert disclosures, and the plaintiff fact sheet is a key part of the process. Claimants’ experts are working to prove general causation by linking prenatal acetaminophen use to increased rates of neurological conditions, with scientific research from institutions like the Johns Hopkins Bloomberg School playing a role.
- Daubert hearings are scheduled for early 2026. These court hearings will see the federal judge hear oral arguments and decide on the admissibility of plaintiffs expert testimony and rebuttal expert testimony—a fundamental step that’ll decide if the acetaminophen litigation proceeds to bellwether (test) trials.
- Defendants still maintain that Tylenol has a track record of safe use and that no clear causal correlation has been established between maternal use and neurodevelopmental disorders. Plaintiffs lawyers continue to pursue Tylenol autism cases, and the America healthy movement seeks accountability from pharmaceutical companies and retailers.
As of October 27, 2025, the prenatal Tylenol lawsuits are in a critical stage of discovery and expert review. The court’s upcoming determinations on expert admissibility will likely shape the trajectory of the litigation, determining whether the lawsuits face significant dismissal or proceed to trial.
Scientific Evidence and Controversies Surrounding Acetaminophen Use During Pregnancy
For decades, medications containing acetaminophen, including Tylenol and paracetamol, were considered safe to use during pregnancy.
However, in 2021, several doctors and scientists made a consensus statement about acetaminophen consumption during pregnancy. They cited its potential to interfere with fetal development, potentially leaving lasting effects on the brain, urinary and reproductive systems, and genital development.
Although the issues these medical experts raise are fundamental, it’s essential to note that their concerns stem from human observational studies and studies done in animals. These studies cannot accurately prove that acetaminophen is the cause of those developmental issues.
Additionally, President Trump’s September 2025 press conference highlights some concerns that acetaminophen may be a cause of autism spectrum disorder.
Furthermore, an August 2025 review evaluated outcomes from 46 previous studies; only seven of these studies specifically examined the link between acetaminophen and autism. Those studies found a direct link between prenatal acetaminophen use and autism.
However, again, this kind of research can’t prove that acetaminophen use actually caused autism in children. Establishing a causal relationship between acetaminophen use and autism requires rigorous scientific criteria, such as the Bradford Hill principles, to rule out confounding factors and demonstrate true causality.
That’s because other factors besides acetaminophen may affect the outcomes. For instance, if a pregnant woman using Tylenol had high fevers, causing them to use acetaminophen in the first place, the illness or fever could be the cause of autism rather than acetaminophen. Ignoring other factors is the reason observational studies aren’t definitive when it comes to establishing the cause of a disease.
Before the press briefing, another study was released that included over 2.5 million children in Sweden. The study concluded there was no definitive correlation between prenatal acetaminophen exposure and autism and that the potential correlation reported by previous studies was likely because of confounding.
That means we need more scientific evidence to confirm the general safety of prenatal acetaminophen exposure. Courts often rely on maternal fetal medicine experts to assess the risks of prenatal acetaminophen exposure, as their expertise is crucial in evaluating potential impacts on pregnancy outcomes and fetal health.
But there’s widespread agreement among medical experts and scientists that the available research doesn’t warrant the prohibition of acetaminophen use during pregnancy. In litigation, expert witnesses from fields such as fetal medicine, epidemiology, and public health are often called upon to provide testimony. Notably, Dr. Andrea Baccarelli, a Harvard public health dean, has served as an expert witness in these cases, lending significant credibility to the scientific and legal evaluation of the evidence.
Importantly, not using acetaminophen also comes with some dangers in some instances. For instance, prolonged pain and high fever might elevate the risk of congenital disabilities or miscarriage.
Always consult with your doctor before taking any medication while pregnant. They may agree that taking acetaminophen, for instance, is the best option– or suggest a better alternative.
Potential Settlement Amounts: What Affected Families Can Expect
The acetaminophen autism claims are still in early stages. No Tylenol autism settlements have been agreed to yet, and there are many legal steps ahead before a settlement is potentially reached.
The acetaminophen autism and ADHD MDL Judge has constantly denied motions to dismiss claims by the defendants, and the acetaminophen litigation is starting to take shape.
Despite the litigation being in its early stages, legal experts project that potential settlement amounts for an individual prenatal Tylenol lawsuit will range between $50,000 and $300,000. The value of an acetaminophen lawsuit will depend on the strength of the evidence and the representation by a qualified law firm.
The claims merged in a multidistrict litigation (MDL) named manufacturers and retailers of generic acetaminophen as defendants. That includes:
- Walmart Inc.
- Johnson & Johnson
- Costco Wholesale Corp
- Rite Aid Corp
- Target Corp
- CVS Pharmacy Inc.
- Walgreens Boots Alliance Inc.
- Safeway Inc.
Tylenol Autism settlements for mothers who took the medication and whose kids subsequently developed autism, ADHD, and other neurodevelopmental disorders will depend on several factors, including:
- Severity of diagnoses
- Quality of evidence
- Damages claimed
If you took Tylenol while pregnant and your child was subsequently diagnosed with autism or ADHD, you may qualify to file an acetaminophen autism claim and recover compensation to cover past and future medical bills, lost wages, and emotional and physical distress.
How to Determine If You Qualify for a Tylenol Autism Lawsuit
If you used acetaminophen or generic equivalents during your pregnancy at high doses or for prolonged periods and your child was later diagnosed with ADHD, autism, or any other neurological condition, you may qualify to file a lawsuit and pursue monetary compensation. Plaintiffs filed claims as part of the broader acetaminophen autism lawsuit, seeking compensation for affected families.
Currently, scientific research establishing a link between autism and prenatal exposure to acetaminophen is still emerging. If courts deem that the evidence of causation is strong enough, you may receive adequate compensation to cover your damages.
Tylenol ADHD and autism lawsuits have merged into an MDL; thus, if the causation evidence exceeds legal obstacles, these lawsuits could be resolved in some form of global settlement.
An experienced attorney can help you determine your Tylenol lawsuit eligibility, and upon qualification, they can help you collect relevant medical and scientific evidence to prove your claims. Also, a skilled attorney can help you calculate damages related to how you and your child have been affected. Plaintiffs lawyers have filed numerous acetaminophen autism lawsuits on behalf of affected families, playing a key role in litigation strategy and case outcomes.

Looking Ahead: What the Future Holds for Tylenol Autism Litigation
There have been numerous turns and twists in the prenatal Tylenol lawsuit, which may have left the litigation for dead. However, these impressive new developments leave everyone unsure about how these lawsuits will proceed. The future of Tylenol autism claims and acetaminophen lawsuits will depend on upcoming court decisions, especially as new scientific evidence and legal arguments are presented.
In a far-reaching move, federal health officials declared that acetaminophen must carry a pregnancy warning because of its potential association with autism, ADHD, and other neurological conditions. As a result, the fundamental fight over the admissibility of expert testimonies becomes a battle over whether judges close the door on the very scientific evidence the executive branch relied on.
The central fight in the acetaminophen neurodevelopment disorder litigation has been over expert testimonies. Complainants and their attorneys rely heavily on Dr. Andrea Baccarelli, a public health dean at Harvard, whose medical research has linked autism risk to prenatal acetaminophen exposure.
Defendants and their lawyers moved to exclude this research under Rule 702 of the Federal Rules of Evidence. However, complainants argue that the highest levels of government have validated this medical research. In fact, Federal agencies, such as the United States Department of Health and Human Services (HHS) and the FDA, have cited the work of complainants’ experts in new national advisories and pregnancy warnings to medical professionals, thereby underpinning their credibility. Essentially, you may ask yourself, how doesn’t this change everything?
The number of Tylenol autism cases being filed in both federal and state courts continues to grow, with ongoing acetaminophen lawsuits and Tylenol autism claims facing challenges related to expert testimony, scientific evidence, and court rulings.
We’ll find out more at oral arguments scheduled for November 17, 2025. At that point, we’ll see how the Second Circuit responds to these legal arguments.
