The top legal official in Texas Paxton is suing the producers of Tylenol, claiming the firms hid safety concerns that the pain reliever presented to pediatric brain development.
The lawsuit follows four weeks after Donald Trump advocated an unproven link between using acetaminophen - alternatively called acetaminophen - throughout gestation and autism in children.
The attorney general is filing suit against J&J, which formerly manufactured the drug, the sole analgesic recommended for pregnant women, and Kenvue, which now manufacturers it.
In a official comment, he said they "misled consumers by making money from suffering and marketing drugs regardless of the potential hazards."
The manufacturer states there is no credible evidence tying Tylenol to autism.
"These corporations misled for generations, intentionally threatening countless individuals to line their pockets," the attorney general, from the Republican party, stated.
The company said in a statement that it was "deeply concerned by the dissemination of inaccurate information on the security of paracetamol and the potential impact that could have on the well-being of women and children in America."
On its official site, the company also mentioned it had "continuously evaluated the pertinent research and there is no credible data that indicates a established connection between using acetaminophen and autism."
Groups acting on behalf of physicians and health professionals concur.
The American College of Obstetricians and Gynecologists has stated acetaminophen - the main ingredient in Tylenol - is among limited choices for women during pregnancy to manage discomfort and fever, which can create major wellness concerns if left untreated.
"In over twenty years of studies on the use of acetaminophen in gestation, no reliable research has definitively established that the use of paracetamol in any period of pregnancy results in neurodevelopmental disorders in children," the group stated.
This legal action references latest statements from the former administration in claiming the drug is reportedly hazardous.
Recently, the former president raised alarms from medical authorities when he instructed expectant mothers to "resist strongly" not to take Tylenol when sick.
Federal regulators then released a statement that medical professionals should contemplate reducing the consumption of acetaminophen, while also stating that "a proven link" between the drug and autism in children has not been proven.
Health Secretary Robert F Kennedy Jr, who oversees the FDA, had promised in April to undertake "a massive testing and research effort" that would determine the origin of autism spectrum disorder in a limited time.
But authorities advised that identifying a sole reason of autism - believed by scientists to be the consequence of a complicated interplay of inherited and surrounding conditions - would not be simple.
Autism spectrum disorder is a form of enduring cognitive variation and condition that affects how individuals experience and engage with the surroundings, and is recognized using physician assessments.
In his lawsuit, Paxton - aligned with the former president who is running for US Senate - asserts the manufacturer and Johnson & Johnson "deliberately disregarded and sought to suppress the science" around acetaminophen and autism spectrum disorder.
This legal action attempts to require the firms "remove any promotional materials" that states Tylenol is secure for women during pregnancy.
The court case echoes the grievances of a collection of mothers and fathers of young ones with autism and ADHD who sued the makers of acetaminophen in 2022.
A federal judge threw out the legal action, stating studies from the plaintiffs' authorities was lacking definitive proof.
