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 ADHD.

Current Tylenol Autism Lawsuits

The emerging research on Tylenol and autism has precipitated an influx of product liability lawsuits against major retailers that carry Tylenol or generic acetaminophen. The lawsuits allege the corporations failed to issue a warning that using the store-brand drug during pregnancy could cause the child to develop autism or ADHD.

In June 2022, a motion was filed asking the JPML to consolidate 19 cases into multidistrict litigation before one judge in order to expedite the proceedings. Since then, more than 30 related actions have been filed.

In September 2022, multidistrict litigation was granted.

In November 2022, the first hearings against Johnson & Johnson and multiple retailers were heard. The defendants named in the Tylenol autism lawsuits include:

  • Costco Wholesale Corporation
  • CVS Pharmacy, Inc.
  • Rite Aid Corporation
  • Safeway
  • Target Corporation
  • Walgreens Company
  • Walmart Inc.

Randy Hargrove, a Walmart Inc. spokesperson, called out the manufacturers and distributors of the drugs: “We expect suppliers to provide safe and quality products that comply with all applicable laws, including labeling requirements. We’ll respond in court as appropriate.” Walmart Inc. does not manufacture the drug.

As of December 2022, Walmart has filed a request for an expedited appeal after a ruling and order refused their request to dismiss two of the cases.

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?

Frequently Asked Questions

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.

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.
