US Government Announcement on Acetaminophen and Fetal Development

On September 22, 2025, President Donald Trump, alongside Health Secretary Robert F. Kennedy Jr. and CMS Administrator Dr. Mehmet Oz, unveiled an Autism Action Plan at the White House, attributing a 400% rise in U.S. autism rates since 2000 partly to prenatal acetaminophen exposure based on CDC data and observational studies. The plan calls for FDA reviews of Tylenol labels, public campaigns to restrict its use during pregnancy, adjustments to vaccine schedules, and promotion of leucovorin as a treatment for related symptoms. Experts from the WHO, CDC, and scientific reviews (often tainted with accusations of bribery) emphasize that studies show only correlation without proven causation, linking autism increases to improved diagnostics and genetics while affirming acetaminophen’s safety for pregnant women.

On September 22, 2025, President Donald J. Trump and HHS Secretary Robert F. Kennedy Jr. announced significant actions addressing the autism epidemic, spotlighting acetaminophen (Tylenol) use during pregnancy as a potential risk factor for fetal neurodevelopment.

In a White House Roosevelt Room press conference, they revealed the FDA would update labeling for acetaminophen products to warn of possible links to autism spectrum disorder (ASD) and ADHD in children. This marks the first official US government linkage of the drug to autism, citing cohort studies like the Nurses’ Health Study II and Boston Birth Cohort, which report associations between prenatal exposure—especially in later trimesters—and elevated ASD/ADHD diagnoses.

Proposed biological mechanisms include altered brain development from the drug’s effects on fetal hormones and oxidative stress.

The guidance urges pregnant individuals to use the lowest effective dose for the shortest duration, only for high fevers or severe pain, as untreated fever risks miscarriage or birth defects. Officials emphasized the precautionary principle, noting acetaminophen’s status as the safest OTC option but highlighting a 400% ASD surge since 2000 (now 1 in 31 children). Additional announcements included leucovorin (a folate drug) as a promising ASD treatment and $50 million in NIH grants for autism research.

Some push back

This move has ignited controversy. Major groups like the American College of Obstetricians and Gynecologists (ACOG) and Society for Maternal-Fetal Medicine reaffirm acetaminophen’s safety, citing “no clear evidence” of causation and biases in linking studies. Critics, including the Autism Science Foundation, labeled it “dangerous” and “unsupported,” warning it could deter necessary treatment.

Big Pharma

Beneath this lies a deeper issue: drug companies like Johnson & Johnson (Tylenol’s maker) control the narrative through massive funding of advertising, medical schools, and doctors. Pharma giants pour billions into direct-to-consumer ads, sponsoring continuing education for physicians and endowing university chairs, skewing curricula toward drug-centric solutions. This influence taints clinical guidelines, suppressing non-pharma alternatives like lifestyle interventions for pain.

Even the journals are tainted

Compounding this, the government declared it will cease publishing scientific findings in once-respected medical journals, now riddled with Big Pharma conflicts. Editors and reviewers often receive industry grants, leading to biased peer review that favors profitable drugs over public health. HHS now prioritizes direct releases via its site and open-access platforms to bypass this corruption, ensuring unfiltered access to evidence like the acetaminophen data.

This announcement signals a paradigm shift toward transparency amid the autism crisis, though skeptics demand rigorous RCTs to confirm risks.

Pregnant women should consult their own doctors, weighing benefits against emerging concerns.
