Tylenol denies Trump's link between acetaminophen and autism

Tylenol's maker rebutted President Trump's warning to pregnant women, saying there is "no credible evidence linking acetaminophen to autism."

Why it matters: Decades of evidence show Tylenol is safe in pregnancy when used as directed, but Trump's claims fueled fears among expectant mothers, pressuring the drugmaker to defend its brand.

• The American College of Obstetricians and Gynecologists continues to back acetaminophen as a safe option during pregnancy, a stance also supported by outside experts.
• The Food and Drug Administration moved to add a pregnancy warning to acetaminophen, even as the agency admitted studies have shown only correlation and not yet causation for any neurological conditions.

Driving the news: Kenvue, Tylenol's maker, responded that untreated fevers and pain — especially in the first trimester — pose risks of their own, framing Tylenol as the safer choice under medical supervision.

Zoom out: Tylenol's ad reflects a shift in how pharmaceutical companies counter political claims and misinformation.

• Kenvue inherited both Tylenol's reputation as a trusted brand and Johnson & Johnson's history of product-safety litigation, including lawsuits claiming its talc-based baby powder caused cancer.
• The backlash against Trump's comments also hit markets: The Johnson & Johnson spinoff saw shares rise 6% Tuesday morning, rebounding from a record low after investors dismissed Trump's claims as unsubstantiated.

What they're saying: In a statement, Kenvue said: "Over a decade of rigorous research, endorsed by leading medical professionals and global health regulators, confirms there is no credible evidence linking acetaminophen to autism. We stand with the many public health and medical professionals who have reviewed this science and agree."

What we're watching: Will parents sue Tylenol and generic manufacturers based on Trump's claims? And will regulators offer stronger guidance to reassure the public about medication use and side effects?
