The manufacturer of Tylenol, the best-selling form of acetaminophen, said Monday that it "strongly disagrees" with President Donald Trump's suggestion that its drug may cause autism.
Kenvue said in a statement that "sound science clearly shows that taking acetaminophen does not cause autism." The company pointed to scientific reviews by multiple government regulators worldwide, including those previously published by the FDA.

In a White House announcement, Trump on Monday promoted unproven ties between Tylenol, vaccines and autism without offering new evidence.
Shares of Kenvue Inc. fell 7.5% in trading Monday, reducing the company's market value by about $2.6 billion. Tylenol's original manufacturer, Johnson & Johnson, spun off the best-selling brand in 2023. In addition to Tylenol, acetaminophen is used in hundreds of other over-the-counter cold and flu formulas.
