Trump warns against Tylenol use during pregnancy, calls for vaccine schedule overhaul

10/28/2025 / By Belle Carter

President Donald Trump urged pregnant women to avoid Tylenol (acetaminophen) due to potential links to autism (ASD) and ADHD in children. He also called for major changes to childhood vaccination schedules, including splitting the MMR vaccine, delaying hepatitis B shots and spreading out immunizations.
Internal FDA documents reveal that agency scientists warned as early as 2016 about neurological risks from acetaminophen during pregnancy. Despite seven out of eight studies linking it to developmental disorders, FDA leadership (including Janet Woodcock, who approved OxyContin) blocked warnings, demanding more research.
The FDA waited until 2023—after Trump and RFK Jr.’s intervention—to issue a cautious statement on acetaminophen risks. Critics argue this delay was due to Big Pharma’s influence and regulatory capture, depriving women of critical safety information.
A class-action lawsuit against Tylenol manufacturer Kenvue alleges the FDA’s inaction hid risks. Courts previously dismissed cases due to lack of “causal links”, but new FDA documents may strengthen plaintiffs’ arguments.
Trump’s push for alternative vaccine schedules clashes with CDC guidelines, sparking backlash from mainstream medicine. Supporters argue spacing out vaccines reduces immune overload risks, while opponents claim it leaves kids vulnerable to preventable diseases.

President Donald Trump issued a stark warning on his Truth Social platform Sunday, Oct. 26, urging pregnant women to avoid Tylenol and advocating for a major overhaul of childhood vaccination schedules.

His post, which linked to an investigation into the Food and Drug Administration‘s (FDA) handling of acetaminophen safety concerns, reignited debates over pharmaceutical risks, government transparency and childhood immunization practices.

The announcement aligns with Trump’s broader “Make America Healthy Again” (MAHA) initiative, spearheaded by Department of Health and Human Services Secretary Robert F. Kennedy Jr., which challenges mainstream medical recommendations.

Internal FDA documents obtained by the Daily Caller News Foundation reveal that agency scientists repeatedly urged officials to warn pregnant women about potential neurological risks tied to acetaminophen—the active ingredient in Tylenol—as early as 2016. Despite mounting evidence linking prenatal exposure to autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), the FDA delayed action for nearly a decade.

A 2016 review by FDA Senior Medical Officer Andrew Mosholder analyzed eight studies, seven of which connected acetaminophen to developmental issues. Mosholder recommended a public advisory, emphasizing that while fever and other painkillers posed risks, Tylenol should be used “sparingly.” Yet FDA leadership, including then-Center for Drug Evaluation and Research (CDER) Director Janet Woodcock—who previously oversaw controversial approvals like OxyContin—rejected the proposal, calling for further studies instead.

By 2022, FDA scientists concluded in an epidemiological review that prenatal acetaminophen exposure was “consistently associated” with ADHD, urging updated guidance. But the agency waited until September 2023—after Trump and Kennedy’s intervention—to issue a cautious statement acknowledging concerns.

“If you look at the evidence as a whole, all of the things that determine the risk of autism make acetaminophen more or less dangerous to an individual,” said Dr. William Parker, a researcher who has collaborated with Kennedy.

Trump’s vaccine recommendations spark backlash

Beyond Tylenol, Trump’s post called for radical changes to childhood immunization, including:

Splitting the measles-mumps-rubella (MMR) vaccine into three separate shots
Delaying the hepatitis B vaccine until age 12
Spreading out vaccinations across five separate doctor visits

These suggestions clash with Centers for Disease Control and Prevention (CDC) guidelines, which endorse combined vaccines to reduce office visits and ensure timely protection. Critics, including mainstream pediatricians, argue that Trump’s approach could leave children vulnerable to preventable diseases. However, advocates of alternative schedules cite concerns over immune system overload and potential links to neurodevelopmental disorders—a theory long dismissed by federal health agencies but championed by Kennedy and vaccine-skeptic groups.

The debate echoes past controversies, such as the retracted (but culturally persistent) 1998 Lancet study tying the MMR vaccine to autism, BrightU.AI‘s Enoch cites. While large-scale studies have debunked such claims, distrust in pharmaceutical companies and regulators has fueled skepticism.

Legal and scientific battles ahead

The FDA’s reluctance to act on acetaminophen warnings now faces scrutiny in court. Law firm Keller Postman, representing plaintiffs in a class-action lawsuit against Tylenol manufacturer Kenvue, obtained the FDA documents via FOIA requests. The firm argues that the agency’s delays deprived women of critical safety information.

In November, the Second Circuit Court of Appeals will hear an appeal after a lower court dismissed the case, with Judge Denise Cote rejecting causal links between Tylenol and autism. Meanwhile, the Biden administration’s Department of Justice cited the FDA’s 2023 review—which omitted Mosholder’s prior recommendations—to defend the agency’s stance.

“It may be prudent, as a precautionary measure, to issue a communication emphasizing that [Tylenol] use in pregnancy should be judicious,” concluded the FDA’s 2022 review, underscoring the tension between incomplete data and potential harm.

Trump’s intervention amplifies long-standing grievances about regulatory capture and pharmaceutical influence, while his vaccine remarks guarantee further polarization. With acetaminophen lawsuits pending and the FDA’s credibility in question, the fallout could reshape public health communication—and parental decision-making—for years to come.
