Tylenol Autism & ADHD Lawsuits & Settlements
Reviewed by Jacobs Kolton, Chtd. Attorneys at Law; Updated May 2026
Tylenol ADHD and autism lawsuits involve allegations that manufacturers and retailers failed to adequately warn pregnant users about a possible link between prenatal acetaminophen exposure and neurodevelopmental conditions, such as ADHD and autism.
Our team of drug injury lawyers and class action attorneys is investigating potential Tylenol lawsuit cases and settlement claims of individuals whose children were diagnosed with autism or ADHD after being exposed in utero (while in the womb) to Tylenol or acetaminophen.
If your child was diagnosed with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD) after being exposed in utero or prenatally to Tylenol or acetaminophen during pregnancy, you may be entitled to recover compensation from a Tylenol acetaminophen lawsuit case or settlement claim.
Acetaminophen (paracetamol) is a non-opioid analgesic and antipyretic medication used to treat pain and fever. According to the FDA, acetaminophen is an active ingredient in hundreds of prescription and over-the-counter (OTC) medicines, including Tylenol (which brand was named after the chemical name of the drug N-acetyl-para-aminophenol).
Autism spectrum disorder (ASD) is a neurodevelopmental condition that affects how a person communicates, interacts with others, and experiences the world. It’s called a “spectrum” because symptoms and abilities can vary widely. Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition that affects attention, self-control, and how the brain manages impulses.
Acetaminophen is one of the most commonly used medications in the United States. In fact, an estimated 2.3 million pregnant women (or 65% of pregnant women) in the U.S use acetaminophen products. Unfortunately, some studies have reported an association between prenatal acetaminophen exposure and later autism or ADHD diagnoses.
Parents of children diagnosed with ADHD and/or autism are now coming forward and filing Tylenol ADHD/autism lawsuits seeking compensation and justice for the harm and suffering they may have endured.

Who May Qualify for a Tylenol Lawsuit
Individuals may qualify for a Tylenol autism or ADHD lawsuit case or settlement claim if they (or a loved one):
- Regularly Used Tylenol During Pregnancy: Took Tylenol (acetaminophen) during pregnancy on a regular basis, potentially exposing the unborn child to the medication in utero.
- Child Was Born Between 2013 and March 2020. The child was born between 2013 and March of 2020.
- Child Was Diagnosed With Autism or ADHD: The child was diagnosed by a medical professional as having autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD).
Other criteria may apply in order to be eligible. Not all individuals or cases qualify for a Tylenol autism or ADHD lawsuit. Individuals may not qualify if: (1) medical factors or unclear timing make it difficult to link the injuries to Tylenol; (2) the mother does not have custody of the child and/or is not the representative or is not willing and able to pursue the claim on the injured child’s behalf, or the mother is not the legal guardian of an incapacitated child, or the mother is deceased and the next of kin is not willing to pursue the claim on her behalf; (3) the injured child is currently 18 years of age or older; (4) the claim is outside the statute of limitations or statute of repose period (if an individual waits too long they may be legally barred from suing); and/or (5) medical records do not support the claims. Individuals may not qualify for other reasons.
Tylenol Lawsuit Complaints Filed Over Autism/ADHD
Families across the country have filed lawsuits seeking compensation after their children were diagnosed with autism or ADHD allegedly linked to prenatal exposure to Tylenol (acetaminophen).
The acetaminophen lawsuit complaints allege that plaintiffs used acetaminophen while pregnant; that acetaminophen interferes with fetal development; that plaintiffs took it because it was marketed as a safe pain reliever for pregnant women; that it was known or should have been known by acetaminophen manufacturers and sellers that prenatal exposure to acetaminophen can cause autism and/or ADHD; that manufacturers and retailers failed to warn expecting mothers about the potential risks associated with using Tylenol during pregnancy; and that had adequate warnings been provided, pregnant women could have avoided or limited acetaminophen use and reduced the risk of harm to their children; and that their children suffered from autism and/or ADHD due to prenatal exposure to acetaminophen.
The acetaminophen lawsuits seek to recover, among other things, compensatory damages, including past and future medical expenses, past and future pain and suffering, emotional distress, mental anguish, loss of enjoyment of life, lost wages, including loss of earnings and loss of earning capacity.
The tylenol lawsuits filed in federal court were consolidated or transferred into a multi-district litigation or MDL for consolidation and coordination of pretrial proceedings, styled In Re: Acetaminophen-ASD/ADHD Product Liability Litigation, MDL Case No. 3043, U.S. District Court for the Southern District of New York (Judge Denise Cote).
Tylenol lawsuits have also been filed in state courts, including, for example, in Illinois, California, Pennsylvania, New Jersey, and Delaware.
Companies Sued For Acetaminophen Injury Claims
Defendants in the acetaminophen lawsuits have included manufacturers and/or retailers of acetaminophen products, such as:
- Johnson & Johnson Consumer Inc.
- Costco
- CVS
- Walgreen
- Safeway
- Target
- Family Dollar
- Rite-Aid
- Dollar Tree
- Kroger
- 7-Eleven
- Big Lots
- Sam’s Warehouse
- Wal-Mart
- Other possible defendants
Although the retail defendants in the acetaminophen lawsuits may sell different brands of acetaminophen, the active ingredient at issue in the tylenol lawsuits is the same: acetaminophen.
Tylenol Lawsuit and Settlement Updates
- November 2025: On November 17, 2025, the U.S. Court of Appeals for the Second Circuit heard oral arguments in the appeal seeking to revive the federal Tylenol autism and ADHD lawsuits. Plaintiffs argued that the MDL judge improperly excluded their general causation experts under the Daubert standard, while defendants argued that the district court correctly found the expert opinions unreliable. The appellate panel did not issue an immediate ruling after the hearing, so the federal MDL dismissal remained in place while the parties waited for the Second Circuit’s decision. A ruling on the Tylenol appeal could come at any time after argument, but complex civil appeals often take several months or longer.
- September 2025: The FDA announced that it had initiated a process for acetaminophen label changes to reflect evidence suggesting a possible association between acetaminophen use during pregnancy and neurological conditions such as autism and ADHD in children. The FDA also issued a related warning letter to physicians on the use of acetaminophen during pregnancy.
- September 2024: Plaintiffs filed an appeal in the U.S. Court of Appeals for the Second Circuit challenging rulings that led to the dismissal of the federal Tylenol autism and ADHD MDL. The appeal asked the Second Circuit to review whether the district court improperly excluded plaintiffs’ expert causation testimony.
- August 2024: In August of 2024, Judge Cote dismissed all pending Tylenol cases in the federal MDL. U.S. District Judge Denise Cote ruled that the remaining Tylenol ADHD claims could not proceed after excluding plaintiffs’ last remaining expert witness.
- July 2024: On July 10, 2024, the Court issued another order excluding another of plaintiffs’ expert witnesses.
- December 2023: On December 18, 2023, the Court issued an order excluding the testimony of five expert witnesses on whom the plaintiffs had relied, each of whom opined that prenatal exposure to acetaminophen causes ADHD and autism. This ruling significantly weakened the federal cases because plaintiffs needed admissible expert evidence to argue that prenatal acetaminophen exposure can cause autism or ADHD.
- October 2022: The federal Tylenol autism and ADHD lawsuits were centralized in multidistrict litigation, MDL No. 3043, in the U.S. District Court for the Southern District of New York. The lawsuits alleged that children developed autism spectrum disorder or ADHD after in utero exposure to acetaminophen.
Studies on Prenatal Acetaminophen Exposure and Possible Links To Autism or ADHD
Several studies have examined whether acetaminophen use during pregnancy may be associated with later autism spectrum disorder, ADHD, or other neurodevelopmental conditions in children. Some observational studies and reviews have reported an association between prenatal acetaminophen exposure and increased risk of ADHD or autism.
For example, a 2018 meta-analysis published in the American Journal of Epidemiology reviewed prior studies on prenatal acetaminophen exposure and neurodevelopmental outcomes. The authors reported that acetaminophen use during pregnancy was associated with increased risk of ADHD, autism spectrum disorder, and hyperactivity symptoms.
A 2021 consensus statement published in Nature Reviews Endocrinology called for precautionary action regarding acetaminophen use during pregnancy. The authors recommended that pregnant individuals use acetaminophen only when medically indicated, consult a healthcare professional when uncertain, and use the lowest effective dose for the shortest necessary time.
A 2025 review using the Navigation Guide methodology evaluated evidence on acetaminophen use and neurodevelopmental disorders. The authors concluded that numerous studies reported associations between prenatal acetaminophen exposure and neurodevelopmental outcomes, including ADHD and autism-related diagnoses.
According to the FDA, “Evidence in recent years has suggested a correlation between acetaminophen use during pregnancy and subsequent diagnosis of conditions like autism and ADHD. Multiple large-scale cohort studies, including the Nurses’ Health Study II and the Boston Birth Cohort, find this association. Some studies have described that the risk may be most pronounced when acetaminophen is taken chronically throughout pregnancy.” However, the FDA has also cautioned that a causal relationship has not yet been established and that “there are contrary studies in the scientific literature.”
Recover Compensation For Tylenol Injury Claims
Plaintiffs who bring Tylenol lawsuits may be able to recover money damages for harms and losses suffered as a result of being diagnosed with ADHD or autism, including compensation for:
- Pain and Suffering: Families pursuing Tylenol autism and ADHD lawsuits may seek compensation for the pain and suffering endured by their children as a result of developmental challenges. Autism and ADHD can create daily struggles with communication, behavior regulation, and social interactions. These difficulties often lead to frustration, isolation, and emotional hardship for both the child and their family, forming a central component of recoverable damages
- Mental Anguish/Emotional Distress: Parents who took Tylenol during pregnancy without knowing of potential risks may experience feelings of guilt and anger after learning of the alleged link to their child’s diagnosis. The emotional toll of navigating an unexpected lifelong condition, combined with uncertainty about the future, constitutes a significant form of mental anguish. Compensation for this distress acknowledges the profound psychological impact on both the child and the family unit.
- Loss of Quality or Enjoyment of Life: Autism and ADHD can affect a child’s ability to participate fully in school, sports, friendships, and everyday activities. Families may also experience restrictions on travel, leisure, or community engagement due to caregiving demands. Lawsuits seek to recover damages for the diminished enjoyment of life experienced by children and their families, recognizing how developmental disorders can limit opportunities and life experiences that others may take for granted.
- Medical Expenses (Past and Future): Treatment and support for autism and ADHD often involve significant medical and therapeutic costs. Families may face expenses for diagnostic evaluations, occupational therapy, behavioral therapy, speech therapy, medications, and ongoing specialist care. These costs can be overwhelming, especially when they are expected to continue throughout the child’s life. Tylenol lawsuits aim to hold defendants accountable for covering both past and future medical expenses associated with these conditions.
- Loss of Income/Future Earning Capacity: Autism and ADHD may limit a child’s future ability to pursue employment or earn income at the same level as peers without these conditions. In addition, one or both parents may have to reduce work hours or leave employment altogether to provide full-time caregiving. Damages for lost income and future earning capacity help address these economic realities, ensuring that families are not financially penalized for circumstances they believe could have been prevented.
- Other Possible Monetary Damages: Beyond direct medical and economic costs, families may also seek to recover damages for special education expenses, assistive technologies, in-home care, transportation to medical appointments, and long-term support services, among others.
Time Is Limited To File A Tylenol Lawsuit
Deadlines known as statutes of limitation and statutes of repose may limit the time that individuals have to file a tylenol lawsuit to try to recover compensation for injuries they claim to have suffered (e.g., autism or ADHD) after being exposed to acetaminophen during pregnancy.
This means that if a tylenol lawsuit claim is not filed before the applicable deadline or limitations period, the injured party may be barred from ever pursuing litigation or taking legal action regarding their ADHD or autism injury claim. That is why it is important to connect with a tylenol injury lawyer or attorney as soon as possible.

A Tylenol autism/ADHD attorney can evaluate your situation, explain your legal options, and protect your family’s rights while you focus on your child’s care and well-being.
Tylenol autism and ADHD cases are handled on a contingency fee basis, meaning clients pay no attorney’s fees unless compensation is recovered.
