Tylenol Lawsuits Allege Connection to Autism
At Riddle & Riddle Injury Lawyers, Tylenol autism lawsuits are more than just legal cases — they are deeply personal. Many of our attorneys and staff have family members and close friends on the autism spectrum, and we understand firsthand the challenges that families face every day. The Centers for Disease Control & Prevention (CDC) estimates that 1 in 31 children in the U.S. have autism spectrum disorder (ASD), and a 2017 study estimated that 2.21% of U.S. adults, or around 5.4 million people, were living with ASD.
We are committed to doing everything possible for affected children and their loved ones.
We are actively investigating Tylenol autism lawsuits nationwide. New research and government initiatives have raised serious concerns that prenatal use of Tylenol (acetaminophen), especially during the second and third trimesters, may be linked to an increased risk of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD).
Our firm is already reviewing claims and is ready to file Tylenol lawsuits on behalf of families who qualify. While this litigation is still in its early stages — and Kenvue, the manufacturer, strongly denies any liability — we believe families deserve answers and accountability. If you or your child may have been affected, call 1-800-525-7111 today for a free, no-obligation case review.
Tylenol Lawsuit Case Criteria
As of early 2026, we are investigating cases that meet the following criteria:
You may qualify if:
- The mother took Tylenol, generic acetaminophen, or generic paracetamol throughout pregnancy.
- Use occurred during the second and third trimesters.
- The child was later diagnosed with autism spectrum disorder (ASD) or ADHD.
Please note that we unfortunately cannot pursue Tylenol cases if:
- The mother does not have custody of the child, is not the legal representative, or is unwilling/unable to pursue the claim on the child’s behalf.
- The child is 18 years or older at the time of intake.
- There is no formal diagnosis of autism or ADHD, and the mother is unwilling to obtain one.
If your family meets these criteria, you may be eligible to pursue legal action — and you may be entitled to compensation. Contact Riddle & Riddle at 1-800-525-7111 today for a free case review.
January 2026 Update
The Tylenol autism and ADHD litigation continues to progress as plaintiffs allege that prenatal exposure to acetaminophen increased the risk of neurodevelopmental disorders, including autism spectrum disorder and attention-deficit/hyperactivity disorder. The lawsuits contend that manufacturers failed to warn pregnant women and healthcare providers about these risks despite a growing body of scientific literature identifying an association between acetaminophen use during pregnancy and adverse neurodevelopmental outcomes. As of January 2026, the litigation remains highly active and focused on expert admissibility and causation.
Key developments this month include:
- The federal MDL remains centralized in the U.S. District Court for the Southern District of New York, where coordinated pretrial proceedings continue to govern thousands of pending claims.
- The court remains focused on general causation issues, with extensive expert discovery involving epidemiology, toxicology, pharmacology, and neurodevelopmental science.
- Defendants continue to challenge plaintiffs’ expert opinions, arguing that existing studies demonstrate correlation rather than causation and fail to establish a reliable biological mechanism.
- Plaintiffs’ leadership is advancing expert theories emphasizing dose-response relationships, biological plausibility related to fetal brain development, and consistency across multiple epidemiological studies.
- No bellwether trials have been scheduled, as the court continues to prioritize Daubert motions and threshold rulings that will determine whether the litigation proceeds toward trial.
Overall, the Tylenol autism and ADHD lawsuits remain at a critical juncture, with expert admissibility expected to determine the viability of large portions of the MDL. As 2026 unfolds, forthcoming rulings on causation and scientific reliability will play a decisive role in shaping whether these cases advance toward bellwether trials, settlement discussions, or significant narrowing of claims.
The Government’s Announcement and Ongoing Research
In September 2025, the U.S. Department of Health and Human Services (HHS) announced a major autism research initiative, highlighting potential risks associated with prenatal acetaminophen exposure. The FDA has since pledged to fund further studies and explore safety labeling changes.
Some studies have suggested a possible link between Tylenol use during pregnancy and later diagnoses of autism or ADHD. Others have shown no clear association. For decades, acetaminophen has been recommended as the safest pain reliever during pregnancy, making these new findings especially concerning. As the science develops, lawsuits are being filed to protect the rights of families who believe they were not adequately warned of these potential risks.
Status of Tylenol Autism Lawsuits
Tylenol autism lawsuits are still in their infancy. No multidistrict litigation (MDL) has yet been formed, but attorneys across the country are actively filing claims. Criteria for eligibility may evolve quickly as new research emerges and as courts begin to weigh in.
If an MDL is eventually established, cases could be consolidated before a single judge, creating more consistent rulings and streamlined proceedings. Until then, families are filing individual Tylenol autism lawsuits, and acting quickly is critical.
If you believe your family has been impacted by the alleged link between Tylenol and autism spectrum disorder or ADHD, don’t wait — please call 1-800-525-7111 for a free, no-obligation case review.
Manufacturer’s Response
Kenvue and other manufacturers of acetaminophen strongly deny that Tylenol causes autism or ADHD. They point to decades of widespread use during pregnancy and insist that acetaminophen remains a safe and effective medication. While they have pledged to cooperate with regulators, they dispute liability for any alleged injuries.
Potential Compensation in a Tylenol Autism Lawsuit
Families pursuing Tylenol autism lawsuits may be entitled to compensation for:
- Medical costs, including therapy and long-term treatment.
- Educational and developmental support.
- Lost wages for parents who must stay home to provide care.
- Emotional pain, suffering, and diminished quality of life.
- Other financial burdens caused by autism or ADHD diagnoses.
Each case is unique, and our attorneys can help you understand the potential value of your claim.

Frequently Asked Questions About Tylenol Autism Lawsuits
What is a Tylenol autism lawsuit?
A Tylenol autism lawsuit is a legal claim against Johnson & Johnson and other acetaminophen manufacturers, alleging that prenatal use of Tylenol during pregnancy may have contributed to autism or ADHD in children. These lawsuits argue that manufacturers failed to adequately warn families of the risks.
Who qualifies for a Tylenol autism lawsuit?
Families may qualify if the mother used Tylenol or generic acetaminophen during pregnancy, especially in the second and third trimesters, and the child was later diagnosed with autism or ADHD. The child must be under 18, and the mother must have custody and be willing to pursue the claim.
Is there proof that Tylenol causes autism?
There is no definitive proof at this time. Some studies suggest a link, while others do not. Litigation is in its early stages, and Kenvue, the manufacturer, continues to strongly deny liability. Ongoing government-funded research may provide more clarity in the future.
Has a Tylenol autism MDL been established?
No, as of now, no federal multidistrict litigation (MDL) has been formed. Attorneys nationwide are investigating and filing cases, and an MDL may be created if claims continue to grow in number.
What compensation is available in a Tylenol autism lawsuit?
Compensation may include medical care, therapy, education, lost wages for parents, and damages for pain and suffering. The potential amount depends on the unique circumstances of each case. It’s important to note that there are never any guarantees of compensation, and as of late 2025, there have been no verdicts or settlements in these cases.
How much time do I have to file a Tylenol lawsuit?
Deadlines vary depending on the state. Statutes of limitations can be strict, so it’s critical to speak with an attorney as soon as possible to protect your rights.
