Tylenol Autism Lawsuit

The Lanier Law Firm is not taking new Tylenol or acetaminophen clients at this time.

Legal action is being taken against retailers of Tylenol and generic acetaminophen on behalf of women who used the drug during pregnancy and whose child developed autism spectrum disorder or ASD and ADHD. Contact The Lanier Law Firm for more information or to file a claim.

Millions of people regularly use Tylenol or generic-brand acetaminophen to relieve mild to moderate pain and reduce fever. Acetaminophen has also long been considered the safest over-the-counter (OTC) pain reliever medication for pregnant women.

However, dozens of product liability lawsuits have been filed against distributors of Tylenol and generic acetaminophen on behalf of women who used the drug during pregnancy and whose children have developed autism spectrum disorder (ASD) or ASD and attention deficit hyperactivity disorder (ADHD).

The increase in Tylenol autism lawsuits has prompted a request for consolidation of the cases into multidistrict litigation (MDL). The motion was heard on September 29, 2022, by the Judicial Panel of Multidistrict Litigation (JPML). On October 5, 2022, the JPML court created the MDL and assigned Hon. Denise L. Cote of the U.S. District Court for the Southern District of New York.

If you regularly used Tylenol or acetaminophen (also called paracetamol) while pregnant and your child developed autism, you may be eligible for compensation from the party responsible. The Lanier Law Firm has extensive experience and success in pharmaceutical liability litigation and is here to fight on your behalf.

Can prenatal use of Tylenol (acetaminophen) cause ADHD or autism?

Acetaminophen is an active ingredient used in several OTC and prescription medicines. Studies show that acetaminophen from the mother’s blood can cross the placenta and enter the baby’s bloodstream.

Acetaminophen is known to change the function of the immune system and the inflammatory response. It may also make cells more sensitive to oxidative stress, which occurs as a result of normal cell metabolism. Researchers believe that these mechanisms could explain how acetaminophen affects fetal brain development.

However, research in this field is still ongoing, and it will likely take years to fully understand the impact that acetaminophen has on a developing baby’s brain. If you are concerned about the use of Tylenol during your pregnancy, speak with your doctor.

Research Linking Tylenol and Autism

Over the past several years, research from high-level institutions, scientists, and health care professionals has revealed that using acetaminophen during pregnancy presents an increased risk of the child developing autism spectrum disorder or ASD and ADHD.

In a consensus statement published in Nature Reviews Endocrinology, nearly 100 scientists and medical professionals shared their concerns about pregnant women using Tylenol. The research presented indicates that Tylenol is not safe to take during pregnancy, and that fetal exposure to acetaminophen could lead to a higher chance of the child developing ASD or ADHD.

The studies also suggest a correlation between the amount of acetaminophen used during pregnancy and the likelihood of the child developing a neurodevelopmental disorder.

The group of experts urged clinicians and agencies to change their guidelines for using acetaminophen during pregnancy while more research is conducted on the effects of the drug on fetal development.

A team at Johns Hopkins analyzed data from the Boston Birth Cohort, a group of mothers and infants who were followed for 20 years after birth. They examined umbilical cord blood for levels of acetaminophen and substances formed by the metabolism of acetaminophen.

Children whose umbilical cord blood contained the highest levels of acetaminophen were approximately three times more likely to be diagnosed with autism than those with the lowest levels. This study relied on direct evidence of Tylenol exposure rather than on maternal self-reporting, which makes the findings more reliable.

In 2018, the American Journal of Epidemiology published an article reviewing studies on acetaminophen use during pregnancy and its effect on the fetus. The data included over 132,000 pairs of mothers and children. The results concluded that acetaminophen exposure leads to a 20 to 30 percent increased risk for neurodevelopmental disorders, including autism and ADHD.

Who can file a Tylenol autism lawsuit?

You may be eligible to file a Tylenol autism claim and pursue compensation if you used Tylenol or acetaminophen during your pregnancy and your child was subsequently diagnosed with ASD or ASD and ADHD.

However, additional information may be needed from you to prove and support your claim:

  • Why was Tylenol or acetaminophen used?
  • Was Tylenol or acetaminophen used during the second and third trimesters, and how frequently?
  • What was the dose taken?
  • How was the baby delivered (c-section, vaginal birth, etc.)?
  • Did the childbirth result in a loss of oxygen?
  • Did the childbirth result in any type of injury to the child?
  • Is the child regularly taking medication for autism spectrum disorder?
  • Does the child have an IEP, 504, or other accommodation for any condition other than autism?
  • Has either parent been diagnosed with autism?

Factors That May Disqualify Someone from Filing a
Tylenol Autism Lawsuit

  • No diagnosis of autism spectrum disorder or ADHD
  • Mother ingested fewer than 10 doses of Tylenol or generic acetaminophen during pregnancy
  • Mother suffered from any of the following: gestational diabetes, gestational hypertension, or any type of infection or fever during pregnancy that required hospitalization
  • Mother used any type of SSRI (selective serotonin reuptake inhibitors, typically used as antidepressants) during pregnancy
  • Mother was over the age of 45 at the time of giving birth
  • Mother consumed alcohol, tobacco, or any illegal drug during pregnancy
  • Mother has a previous child that was diagnosed with autism and did not use Tylenol or acetaminophen during that pregnancy
  • Mother gave birth before 26 weeks of pregnancy
  • Child was born before 2005 or after March 26, 2020
  • Pregnancy and/or childbirth occurred in Michigan
  • Child has been diagnosed with any of the following: Down syndrome, Fragile X syndrome, Tourette syndrome, or tuberous sclerosis

How much is the Tylenol autism lawsuit worth?

Pharmaceutical and product liability claims are often resolved through settlement. Since the Tylenol autism lawsuit is ongoing as of December 2022, it is difficult to predict the compensation that will be awarded to the plaintiffs. We will keep this space updated as litigation develops.

Autism and ADHD FAQs

ASD is a developmental condition caused by differences in the brain. People with ASD may have difficulty with social communication and interaction, repetitive or restrictive behaviors, and different ways of learning, moving, and paying attention.

The World Health Organization estimates that one in every 100 children worldwide has autism spectrum disorder.

There is no single cause of autism spectrum disorder. Although the disorder is not completely understood, research suggests that it can develop from genetic and nongenetic influences.

According to the National Institute of Environmental Health Sciences, scientists have discovered that certain genetic variations are more common in people diagnosed with autism. These changes in genes increase the risk—but do not guarantee—a child will develop autism. The gene variations may be passed on to the child from the parent, or they may occur in the embryo.

Other risk factors that increase the likelihood that a child will develop ASD include:

  • Having a sibling with autism
  • Having older parents
  • Prenatal exposure to air pollution or to certain pesticides
  • Maternal obesity, diabetes, or immune system disorders
  • Extreme prematurity or low birth weight
  • Problems during the process of birth which cause periods of oxygen deprivation
  • The presence of certain genetic conditions, such as Down syndrome, Fragile X, or Rett syndrome

The Centers for Disease Control and Prevention (CDC) states that signs of ASD can sometimes be detected in a child at 18 months of age or younger and can reliably be diagnosed by age 2. However, many children don’t receive a professional diagnosis until they are older.

Signs of autism can vary from person to person but may include:

  • Avoidance of eye contact
  • Delayed language development
  • Strong resistance to changes in routine
  • Restricted interests
  • Unusual and intense reactions to sounds, smells, tastes, or textures

If you are concerned about the rate at which your child is developing or if you have noticed differences in their behavior compared with other children, consult your child’s primary care doctor and see if autism screening may be warranted.

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children. According to the CDC, children with ADHD are overly active and have trouble paying attention and controlling impulsive behaviors.

The causes and risk factors of this condition are not completely understood. Research shows that genetics as well as other factors may play a role in the development of ADHD, including brain injury, alcohol and tobacco use by the mother during pregnancy, premature delivery, and exposure to substances such as lead during pregnancy or early childhood.

If a child has ADHD, they may:

  • Squirm or fidget a lot
  • Forget or lose things frequently
  • Talk too much or daydream a lot
  • Have trouble taking turns or getting along with others
  • Take unnecessary risks or make careless mistakes
