Research links Tylenol to Autism

Several peer-reviewed studies have shown that exposure to acetaminophen during pregnancy increases the likelihood of autism. 


Specifically, research from Johns Hopkins University Bloomberg School of Public analyzed data from the Boston Birth Cohort. The Boston Birth Cohort is a long-term study of factors influencing pregnancy and child development.

Through measuring the amount of acetaminophen and two of its byproducts in samples collected from umbilical cord blood, researchers found that, on average, by the time children were 8.9 years old, 6.6% were diagnosed with Autism Spectrum Disorder.

Further, the authors of the study classified the amount of acetaminophen and its by-products into thirds, from lowest to highest. Compared to children exposed to the least amount of acetaminophen in utero, those with middle-third exposure were 2 times more likely to develop autism. Similarly, those in the highest exposure group were 3 times as likely to develop autism.

The 2019 study concluded that the results support previous studies linking acetaminophen exposure in the womb to autism and underscored the need for additional research.

The results may take years to become available.Several risks come from an untreated fever during pregnancy. If you are running a fever or suffering in pain, consult with your doctor about the dangers of acetaminophen during pregnancy. 

What Neurological Issues can a Child Develop from Tylenol use during pregnancy?

The Tylenol/Autism Mass Action Litigation

Thousands of children and parents affected by autism, ADHD, and other negative diagnoses because of Tylenol or acetaminophen have already filed claims. 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 Court 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.

While the lawsuits are at an early stage, the attorneys representing those affected are encouraged and impressed by the way the judgeis handling the case and claims.
