Why Does Tylenol Cause Chronic Illnesses Like Autism?

The Presidential Announcement

September 22, 2025, President Trump held a press conference about the potential causes of autism. Shortly beforehand, the press became aware that Trump would focus on the link between Tylenol and autism, resulting in the national media collectively ridiculing that link immediately before the press conference.

In that press conference, Trump stated he had felt very strongly about bringing attention to vaccines and autism for 20 years, that he felt we were giving too many shots too quickly, and that they needed to be spaced out. There was no reason to give the hepatitis B vaccine prior to children being 12 (which, as I showed here, is true), and Tylenol increases the risk of autism, so if possible, it should be avoided during pregnancy, and you should not give it to infants.

Secretary Kennedy added that some 40% to 70% of mothers who have children with autism believe a vaccine injured their child, and that President Trump believes we should be listening to these mothers instead of gaslighting them.

Note: Regrettably, to show they believed in “Science,” pregnant mothers began quickly posting videos of themselves taking large amounts of Tylenol (which I compiled on 𝕏 here — including one tragic overdose1).

Over-the-Counter Pain Management

Because of how uncomfortable pain is, pain treatments have long been a core market in medicine. Remarkably, however, most standard pain therapies have serious issues and often lead patients to needing more and more severe interventions.

Typically, the first-line treatment for pain is an over-the-counter medication, such as acetaminophen (Tylenol), ibuprofen (Advil or Motrin), naproxen (Aleve), aspirin, or topical diclofenac (Voltaren gel). Unfortunately, these medications all have dose-dependent toxicity and typically only elicit partial improvement in pain. Many consider NSAIDs (ibuprofen and naproxen) among the most hazardous drugs in the U.S. because:

•They are the leading cause of drug-related hospital admissions — Often due to heart attacks, strokes, bleeding, and kidney failure2 (e.g., at least 107,000 Americans are admitted to hospitals each year for NSAID GI bleeds).3

•Kidney damage is a significant risk — One study found a 20% increased risk of kidney disease from NSAIDs;4 others found up to 212%.5 Amongst kidney failure patients, 65.7% were found to be chronic NSAID users.6

•NSAIDs raise cardiovascular risks — NSAIDs also increase the risk of heart attacks and death (e.g., extensive studies have found between a 24% to 326% increase7,8,9). Two of the worst ones, Vioxx (Merck)10 and Celebrex (Pfizer),11 were designed to reduce stomach bleeding but instead caused heart attacks and strokes.

Merck hid data on Vioxx’s risks; eventually it was withdrawn after an estimated 120,000 deaths.12 Celebrex, still on the market, has been linked to 75,000 deaths.13 Merck’s handling of Vioxx14 later informed how pharma pushed the HPV vaccine and mRNA vaccines.15

•Gastrointestinal bleeding is common and often fatal — In 1999, over 16,000 Americans died from it.16 NSAIDs also cause small bowel damage in over 50% of chronic users17 — often undetected — leading to “small bowel enteropathy” and possibly chronic illness through gut permeability.18

•They impair healing, especially of ligaments, creating long-term re-injury risk.19

How Vaccine Brain Injuries Were Rebranded and Erased From Memory

I’ve long believed that public relations (propaganda) is one of the most powerful but invisible forces in our society. Again and again, I’ve watched professional PR firms create narratives that most of the country believes, regardless of how much it goes against their self-interests. What’s most remarkable is that despite the exact same tactics being used repeatedly on the public, most people simply can’t see it. When you try to point out exactly how they’re being bamboozled by yet another PR campaign, they often can’t recognize it—instead insisting you’re paranoid or delusional.

That’s why one of my major goals in this publication has been to expose this industry. Once you understand their playbook—having “independent” experts push sculpted language that media outlets then repeat—it becomes very easy to spot, and saves you from falling into the traps most people do. The COVID-19 vaccines, for instance, were facilitated by the largest PR campaign of our lifetime.

One of the least appreciated consequences of this industry is that many of our cultural beliefs ultimately originate from PR campaigns. This explains why so many widely believed things are “wrong”—if a belief were actually true, it wouldn’t require a massive PR investment to instill in society. Due to PR’s power, the viewpoints it instills tend to crowd out other cultural beliefs.

In this article, we’ll take a deeper look at what’s behind one of those implanted beliefs: “vaccines don’t cause autism.”

FDA Stayed Silent As Internal Reports About Potential Tylenol Risks Piled Up

The Food and Drug Administration (FDA) defied the advice of its own drug safety experts to warn pregnant women about Tylenol for nearly a decade, internal reports and presentations obtained by the Daily Caller News Foundation reveal.

FDA rank-and-file scientists repeatedly recommended the agency release information about Tylenol in pregnancy across three scientific reviews conducted in 201620192022 and two memos, one from the FDA’s maternal health division in 2016 and one from the FDA’s urological health division in 2017.

The scientific literature posits many plausible drivers of autism, the most well-established of which are genetic, and the FDA drug safety experts acknowledged that the research linking the condition to Tylenol is far from ironclad.

Still, as alarm bells rang within FDA headquarters and the boardrooms of Tylenol’s manufacturers, pregnant women heard nothing from either the government or the manufacturers about the potential risks until the September announcement by President Donald Trump and Health and Human Services Secretary Robert F. Kennedy Jr.

FDA leadership declined to update its webpage about over-the-counter painkillers in pregnancy, repeatedly falling back on language first issued in January 2015. But that statement simply acknowledged that “FDA is aware of concerns” about Tylenol and attention deficit hyperactivity disorder (ADHD), citing just one scientific paper.

At the urging of Trump and Kennedy, FDA finally released a nuanced statement in September cautioning pregnant women about Tylenol while acknowledging that aspirin, ibuprofen and high fevers all pose their own risks. That move was first recommended by an FDA drug safety expert nine years earlier.

The DCNF obtained the FDA documents from the law firm Keller Postman LLC, which brought a class action lawsuit against Tylenol maker Kenvue, a legally independent spinoff of Johnson & Johnson. The personal injury law firm, which often brings class action lawsuits, obtained the documents from FDA via the Freedom of Information Act.

Tylenol, a brand name for acetaminophen, first received FDA approval in 1955 before modern drug laws tightened clinical trial requirements in 1962.

Some experts argue that neurological damage occurs due to a toxic byproduct of acetaminophen called NAPQI. Babies and children with autism may struggle to metabolize the drug, resulting in higher levels of NAPQI, which kills cells.

Erasing Encephalitis — Why Vaccine Brain Injuries Became Autism

Trump Derangement Syndrome comes for heralded off-label autism treatment after president endorses

he medical establishment and mainstream media are uniting against the Trump administration’s re-purposing of an inexpensive drug to treat an epidemic, calling it “unproven,” not “backed by science,” “not a cure” and “shocking” to endorse, with The New York Times emphasizing no profit-driven drug company suggested it.

In President Trump’s first term, it was ivermectin and hydroxychloroquine to treat COVID-19. In his second, it’s prescription leucovorin to treat autism spectrum disorder.

Long used to treat chemotherapy side effects, leucovorin calcium tablets got approved last week by the Food and Drug Administration to treat “cerebral folate deficiency” (CFD), whose clinical symptoms include “global developmental delays with autistic features,” following its own “systematic analysis of literature” from 2009 through last year.

“Published case reports provided patient-level data on over 40 patients,” adult and child, with most of those given leucovorin treatment showing “substantial improvement of symptoms of CFD that would not be expected when compared to the natural history of CFD due to FOLR1 gene variants,” the Federal Register notice says.

Health and Human Services Secretary Robert F. Kennedy Jr. touted leucovorin to treat autism Monday with Trump and Centers for Medicare and Medicaid Services Administrator Mehmet Oz, but it was quickly overshadowed by the other autism-related recommendation that pregnant women limit their use of Tylenol, which prompted a new TikTok challenge.

Mount Sinai: Prenatal Acetaminophen Exposure Increases Risks of Autism and ADHD in Children, According to Analysis of 46 Global Studies

Amid growing concern over neurodevelopmental disorders, a recent study from Mount Sinai Hospital has reignited the debate surrounding acetaminophen, commonly known as paracetamol or Tylenol.

This analgesic, used by over 50% of pregnant women worldwide to relieve pain and fever, maybe linked to an increased risk of autism and attention deficit hyperactivity disorder (ADHD) in their children.

The report, published in August 2025 in the journal Environmental Health, analyzed 46 previous studies from international groups.

It applied the Navigation Guide methodology, a rigorous framework for evaluating environmental evidence. The findings show a consistent association: prenatal acetaminophen exposure increases the risk of autism by 19% (odds ratio 1.19) and ADHD by 26% (odds ratio 1.26).

Diddier Prada, MD, PhD, lead researcher at the Icahn School of Medicine at Mount Sinai, emphasized: “Our findings indicate that higher-quality studies are more likely to show a link between prenatal acetaminophen exposure and elevated risks of autism and ADHD.”

The analysis included 20 studies on ADHD, eight on autism, and 18 on other neurodevelopmental disorders. This is not an isolated finding. A 2019 Johns Hopkins study, based on umbilical cord blood samples from 996 children, found that high acetaminophen levels tripled the risk of autism (up to 3.62 times) and doubled the risk of ADHD (up to 2.86 times).

Researchers measured metabolites in blood at birth and followed the children for an average of 8.9 years. Another study, funded by the NIH in 2025, confirmed similar patterns: the middle third of exposure increased the risk of ADHD by 2.26 times and autism by 2.14 times.

These data come from cohorts such as the Boston Birth Cohort and the Nurses’ Health Study II. The underlying biology points to concerning mechanisms. Acetaminophen crosses the placental barrier and can induce oxidative stress, disrupt hormones, and cause epigenetic changes that interfere with fetal brain development. The risk appears heightened in the third trimester, when the brain develops rapidly.

In September 2025, the U.S. FDA responded with a letter to clinicians, initiating changes to product labels like Tylenol’s. It cited “accumulated evidence” of an association with autism and ADHD, recommending minimal doses and short-term use.

Joe Rogan Stunned by Liberal Pregnant Women Downing Tylenol to Own Trump: ‘This Science Came From Harvard’

People have often joked that if Trump said breathing air is good for you, liberals would start dying of suffocation. Now we know there is some real truth behind that.

As the Gateway Pundit has reported, once the Trump administration cautioned pregnant women from taking Tylenol, pregnant liberal women started going on the internet and downing Tylenol, even filming it, in some cases with disastrous results.

On a recent episode of his podcast, Joe Rogan commented on this, noting that this science has been backed up by Harvard.

The Daily Caller reports:

Podcast host Joe Rogan on “The Joe Rogan Experience” Friday called out pregnant women who have been filming themselves consuming Tylenol in objection to President Donald Trump’s administration’s recommendation not to do so.

TikTok users ingested large amounts of Tylenol to mock Trump and Health and Human Services Secretary Robert F. Kennedy Jr. after announcing the findings of an association between the use of acetaminophen by pregnant women and autism diagnoses in children. Rogan noted on his podcast that the Trump administration cited a Harvard study to support its findings.

“I’ve been fascinated by these videos of pregnant women taking Tylenol to show Trump that they don’t believe in what RFK Jr. is saying, that it’s somehow or another anti-science — when this science came from Harvard,” Rogan said. “That’s where the study came from. He’s not making things up. And these people are like on TikTok — they’re pregnant women taking Tylenol.”

SCOOP: Tylenol Maker Privately Admitted Evidence Was Getting ‘Heavy’ For Autism Risk In 2018

The pharmaceutical company behind Tylenol privately acknowledged the likelihood of an association between its drug in pregnancy and neurodevelopmental disorders like autism in children seven years ago, company documents obtained by the Daily Caller News Foundation show.

“The weight of the evidence is starting to feel heavy to me,” said Rachel Weinstein, U.S. director of epidemiology for Janssen, the pharmaceutical arm of Johnson & Johnson, in 2018. Johnson & Johnson marketed Tylenol at the time but in 2023 spun off its consumer products division into a separate company called Kenvue.

Legacy media headlines and vocal public health experts have dismissed the conclusion of President Donald Trump and Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. that Tylenol taken in pregnancy and early infancy has driven rises in autism. But one stakeholder has for years viewed the evidence as credible enough to act upon, at least privately: The makers of Tylenol.

RFK Jr. Considering Adding Autism Symptoms To Vaccine Injury Program

Health Secretary Robert F. Kennedy Jr. is looking at updating symptoms after vaccination that are eligible for compensation under a federal program, an adviser said on Sept. 25.

We have a team looking at … a way to capture these kids,” Andrew Downing, senior policy adviser at the Department of Health and Human Services (HHS), told an autism roundtable in Washington.

“Do we broaden the definition of encephalopathic events? Do we broaden neurological injuries? How do we do that?

I was hoping that the changes to the program might have been rolled out before today, so that I could talk more in depth about them. As you can imagine, it’s not my place to do the rollout.

Downing is a lawyer who has represented individuals seeking compensation from the National Vaccine Injury Compensation Program.

The program was established by Congress to award damages to those who suffer vaccine-related injuries. He joined the HHS after Kennedy took office in February.

Kennedy said over the summer that the program would be revolutionized, including by addressing the lack of discovery.

The program has an enormous backlog of thousands of cases, just eight special masters who are able to adjudicate cases, and a table of eligible injuries that critics argue is too small.

Downing told the crowd on Thursday that when he first began filing cases with the program, encephalopathy cases could be approved for compensation if there was supportive medical literature. In rare cases, lawyers would have to bring in an expert.

The definition was changed in the 1990s, “making it almost impossible for a family to prevail,” he said.

The Department of Justice, which represents the HHS in cases filed with the program, later made it even harder to win some cases, according to Downing.

One change that should happen is that in borderline cases, compensation should be awarded to injured people, Downing said.

That is how the vaccine program was originally designed, and it’s been hijacked, for lack of a better word. Hopefully not for much longer,” he added.

The Vaccine Schedule Finally Under Fire

Well, Donald Trump did it. He scheduled a news conference on the science of autism, what we know and what we do not, and handled it masterfully. He is profoundly aware that as a parent and the president of the United States that he can make points that his own science advisors cannot make for reasons political, sociological, and scientific.

Trump, however, knows that expecting mothers and families still have to make decisions and those decisions could affect the health and well-being of their children for the rest of their lives. Nothing is more important. Meanwhile, autism is an epidemic. Something is causing this.

There is no such thing as a genetic epidemic. Nor is this traceable to changed definitions of the term else we would see a growing distribution among adults too, which we do not. FDA head Marty Makary, normally very cautious and careful in his statements, said the straightforward thing that no one has stated as clearly: autism is preventable.

Though Robert F. Kennedy, Jr., Jay Bhattacharya, and Mehmet Oz were there and speaking, it was Trump who bravely took the burden upon himself to say what vast numbers of parents and doctors suspect and know but have heretofore occupied the realm of forbidden thought. He laid out two main culprits: Tylenol for birthing mothers and infants and the packed vaccine schedule that hits tiny babies with a cocktail of shots that have never been studied in their combined effects.

Trump was extremely clear.

Don’t take Tylenol. Also the schedule should be changed so that each shot is a separate vaccine spaced out over years. Further, some shots like HepB should wait until the age of 12 if they are taken at all. This would mean no more MMR, much less an MMRV shot that adds chickenpox to the soup. It would mean one shot for measles, one for mumps, one for rubella, and so on.

The products do not currently exist in that form. The whole trajectory has been to batch them up and this happened at the same time we’ve seen an explosion in autism cases. It is not a stretch at all to assume a connection. And Trump explained the stories of so many mothers, more than half, who report dramatic and immediate behavioral and cognitive changes following a vaccine.

These people have been gaslighted for 40 years. They have been called all sorts of terrible names. The scientists who have taken up their case have been shut out of academia, professional societies, journals, and been declared nonpersons. But they never relented. Trump has personally agreed with them for 20 years, a dating of his own. He and Kennedy have long had private discussions about it.

The entire field is a landmine filled with dangers both cultural and industrial. At some point, Trump realized that if anyone was going to break the logjam on this topic, it would need to be him. So he did it, and went much further than anyone—I mean anyone!—expected.
