Texas Attorney General Paxton is taking legal action against the makers of acetaminophen, claiming the corporations withheld safety concerns that the drug presented to children's cognitive development.
The lawsuit follows a month after Donald Trump advocated an unsubstantiated connection between using Tylenol - referred to as acetaminophen - throughout gestation and autism in young ones.
Paxton is suing Johnson & Johnson, which previously sold the medication, the exclusive pain medication recommended for women during pregnancy, and the current manufacturer, which presently makes it.
In a declaration, he said they "betrayed America by gaining financially from suffering and pushing pills regardless of the risks."
Kenvue states there is lacking scientific proof tying Tylenol to autism spectrum disorder.
"These companies deceived for years, intentionally threatening numerous people to boost earnings," the attorney general, a Republican, said.
Kenvue stated officially that it was "very worried by the spread of false claims on the reliability of acetaminophen and the potential impact that could have on the health of US mothers and children."
On its online platform, the company also mentioned it had "continuously evaluated the applicable studies and there is no credible data that indicates a proven link between using acetaminophen and autism."
Associations acting on behalf of physicians and healthcare providers agree.
ACOG has stated acetaminophen - the key substance in acetaminophen - is a restricted selection for women during pregnancy to treat pain and fever, which can present serious health risks if left untreated.
"In over twenty years of research on the consumption of acetaminophen in gestation, not a single reputable study has successfully concluded that the usage of paracetamol in any trimester of gestation leads to brain development issues in children," the organization stated.
The lawsuit cites latest statements from the Trump administration in arguing the drug is reportedly hazardous.
Recently, the former president generated worry from medical authorities when he advised expectant mothers to "fight like hell" not to consume Tylenol when ill.
Federal regulators then published an announcement that doctors should think about restricting the usage of Tylenol, while also stating that "a proven link" between the medication and autism spectrum disorder in young ones has not been proven.
The Health Department head Kennedy, who supervises the FDA, had promised in spring to conduct "a massive testing and research effort" that would establish the cause of autism spectrum disorder in a matter of months.
But experts cautioned that discovering a single cause of autism spectrum disorder - believed by scientists to be the result of a complicated interplay of inherited and external influences - would be difficult.
Autism spectrum disorder is a form of lifelong neurodivergence and impairment that affects how individuals perceive and interact with the environment, and is diagnosed using medical professional evaluations.
In his court filing, Paxton - who supports Trump who is running for the Senate - asserts the manufacturer and J&J "intentionally overlooked and tried to quiet the evidence" around acetaminophen and autism spectrum disorder.
The case attempts to require the corporations "eliminate any promotional materials" that claims Tylenol is secure for expectant mothers.
The Texas lawsuit mirrors the complaints of a assembly of mothers and fathers of young ones with autism spectrum disorder and ADHD who filed suit against the manufacturers of Tylenol in 2022.
A federal judge threw out the legal action, declaring studies from the plaintiffs' authorities was lacking definitive proof.
