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% increase^7,8,9). 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
