Did you take Tylenol while pregnant?

Has your child been diagnosed with autism or ADHD?


In recent studies by John Hopkins and other reputable research facilities have reported a 20% to 30% increase in autism and/or ADHD in children born to mothers who took Tylenol while pregant. In 2021, Nature Reviews Endocrinology published a consensus statement on the warning of use Tylenol while pregnant.


Twenty years of data have been compiled that show children whose umbilical cord blood samples contained the highest levels of acetaminophen were roughly three times more likely to be diagnosed with ADHD or autism spectrum disorder. The research also found a link between acetaminophen use and language delays, oppositional defiant disorder, and other developmental disorders.


The use of this over-the-counter pain relief drug is so ubiquitous that one study couldn’t find a single person without some level of acetaminophen in their bloodstream.


Many of the children diagnosed with these conditions live happy lives. Yet others may require lifelong care and support. Many of these children struggle with reduced career opportunities over the course of their lifetimes. Many children with ADHD or autism need costly special care and training. Some parents have had to forgo their careers or pay for expensive home care to take care of the children that have been harmed by these illnesses.


Merchant Law Group LLP is preparing to launch class action litigation against Johnson and Johnson on behalf of Canadian families whose child has been diagnosed with ADHD or autism after regular use of Tylenol during pregnancy.
