    To save you some time, here are the key points discussed in our June 2023 Tylenol Lawsuit Update video:

    • The court has issued two (2) significant orders since our last update in May 2023.
    • The first order could potentially affect cases in Texas due to the state’s “Safe Harbor Act“.
      • The Safe Harbor Act protects retailers that follow FDA guidelines from being sued.
      • However, this argument was not successful when tried in California.
    • The second order is related to the Plaintiff Fact Sheet, a form that plaintiffs need to fill out within a certain period of time from filing a lawsuit.
      • It is crucial for plaintiffs to complete all forms, questionnaires, and other onboarding documents as quickly as possible.

  • May 24, 2023 Update:

    The Tylenol Autism Lawsuit is ongoing and our lawyers are talking to clients about their potential cases. 

    In recent developments, a Texas judge granted a motion to dismiss failure to warn claims against major retailers like CVS, Target, and Walmart, citing a state law that protects distributors if FDA-approved packaging is used.

    This decision halts failure to warn lawsuits in Texas but leaves other claims in progress.

    In California, a similar motion was denied, indicating the outcome may vary depending on the state.

    If you used Tylenol during pregnancy and your child was diagnosed with ASD, ADHD, or other developmental disorders, consider contacting Keith Law Group for a free consultation regarding a potential Tylenol Lawsuit.

    • Preemption is a hurdle in prescription drug and product liability cases.

    YouTube video
  • April 12, 2023 Update:

    In the following video Sean Keith provides an April update on the Tylenol acetaminophen litigation.

    In summary, the litigation is very busy right now as documents are being exchanged and reviewed from the manufacturers of acetaminophen.

    As a reminder, this case is a failure to warn case, alleging that manufacturers and retailers knew about the possible dangers of acetaminophen taken during pregnancy and failed to warn of that.

    The manufacturers and retailers should have simply added one sentence to warn of the possible dangers for pregnant women.

    The court approved a plaintiff profile form about 10 days ago. When cases get filed, plaintiffs will need to help fill out the plaintiff profile form, which will include using medical records to complete the form.

    Litigation is ongoing and a ton of important work is being done, so we will release another update by the end of this month!

  • October 5, 2022 Update:

    Acetaminophen Autism-ADHD Lawsuits are being consolidated in multidistrict litigation (MDL) in the US District Court: Southern District of New York.

    The Judicial Panel on Multidistrict Litigation (JPML) certified the creation of an MDL that names the manufacturers of generic acetaminophen as defendants, including Walmart, Walgreens, CVS, and other companies.

    MDL is a legal procedure used in cases where injuries and causation are similar across several lawsuits, centralizing them in a single US District Court to make them easier to manage and ensure that there is a standard held across all similar cases in terms of court rulings.

Tylenol And Autism/ADHD Claims

Tylenol (generically known as Acetaminophen) is one of the most widely used medications in the world. Tylenol is a pain relief and fever reduction medication that is available over-the-counter on shelves of supermarkets and drug stores around the world.

Acetaminophen is the active ingredient in Tylenol and is present in over 600 over-the-counter drugs sold across the world.

According to the Consumer Healthcare Products Association, products with an active ingredient of Acetaminophen are used by 23% of US adults each week – over 52 million people.

Does Acetaminophen Cause Autism Or ADHD?

Research from several high-level institutions and healthcare professionals across the world has concluded that Tylenol usage during pregnancy may present an increased risk for a child to develop Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD) later in life.

The following research studies completed on Tylenol use and the potential onset of neurodevelopmental disorders include the following:

  • Researchers from Denmark and Spain conducted studies on birth cohorts and groups that totaled over 65,000 children and mothers and found that acetaminophen exposure was associated with higher rates of Autism Spectrum Disorder and Complex Developmental Disorder.
  • A 2018 study published in the American Journal of Epidemiology studied over 130,000 pairs of mothers and children and found a 20% higher risk of autism and a 30% higher risk of ADHD for children who had prolonged exposure to acetaminophen in the womb.
  • Researchers from Johns Hopkins University and the US Department of Health and Human Services published a study that found that cord plasma biomarkers of fetal exposure to Acetaminophen and cord blood samples contained a higher risk for ADHD diagnosis.

Apart from Autism/ADHD, Danish and Norwegian researchers analyzed data from the Norwegian Mother and Child Cohort Study and concluded that acetaminophen use when pregnant was also associated with an increased risk of Cerebral Palsy in Children.

Is Acetaminophen Use During Pregnancy Safe?

Doctors have traditionally stated that acetaminophen or Tylenol in low doses is suitable for use by pregnant women.

Health professionals warn against prolonged use of acetaminophen due to the health risks it may pose.

The links between Tylenol and Autism or ADHD are still being studied and more sweeping scientific information will be available in the years to come.

You should always consult with your doctor before taking any medication, especially when pregnant.

However, autism and ADHD are on the rise in the United States:

It’s generally unclear what is to blame for the higher rates of ADHD diagnosis and Autism Spectrum Disorder diagnosis in recent years.

These higher rates could be because of more open-ended guidelines for diagnosis, but could potentially be linked to environmental factors such as Acetaminophen exposure during pregnancy.

Tylenol Use During Pregnancy May Increase A Child’s Risk Of Neurological Disorders

The use of Acetaminophen while pregnant may put a developing fetus at a greater risk of being diagnosed with ADHD or Autism Spectrum Disorder later in life.

Research from scientists, doctors, health professionals, and health agencies all over the world indicates that Tylenol use may contribute to the onset of developmental disorders and symptoms such as:

  • Attention deficit hyperactivity disorder (ADHD) symptoms
  • Autism Spectrum Disorder (ASD)
  • Language Delays
  • Oppositional Defiant Disorder
  • Conduct Disorder
  • Decreased executive function
  • Decreased IQ levels

This is not a full and complete list of potential diagnoses from Acetaminophen exposure in the womb.

As scientific research and interest increases in these claims, more information and potentially more developmental disorders could be earmarked as being related to Acetaminophen exposure in unborn children.

Scientists Sound the Alarm: Health Effects From Acetaminophen Exposure

Paracetamol use during pregnancy – a call for precautionary action” is a September 2021 Consensus Statement published in Nature Reviews Endocrinology that provides a warning to the public of the many potential risks associated with Acetaminophen use in pregnancy.

This new study builds off decades of scientific research conducted on birth cohorts and mother-child pairs: summarizing scientific evidence that chronicles the usage patterns, diagnoses, health impacts, and more over long periods of time relating to the use of Acetaminophen during pregnancy.

Is There A Tylenol Birth Defect Lawsuit?

Lawyers are currently investigating the claims made against the drug manufacturers and are preparing for legal action.

A few lawsuits have been filed for Autism diagnoses relating to acetaminophen use while pregnant.

Claims have been filed in 6 states, but nothing has made it to court yet.

On June 10, 2022 a motion was filed to centralize all Tylenol (Acetaminophen) Autism ADHD lawsuits (19 in total).

Defendants originally had just five days to respond to the claims, but an extension was granted, and they now have until July 26 to respond.
