You’ve probably seen the headlines or heard the clips from that chaotic afternoon in late September 2025. President Trump stood in the Roosevelt Room, flanking Robert F. Kennedy Jr., and essentially told every pregnant woman in America to "tough it out." He was talking about pain. Specifically, he was talking about Tylenol.
The claim was blunt. Trump said taking Tylenol—or any acetaminophen—during pregnancy is "not good" and linked it directly to the "autism epidemic." It sent shockwaves through doctor's offices. Within hours, phones were ringing off the hook at OB-GYN clinics. People were panicked. But if you look at the actual science vs. the political rhetoric, the "Trump saying Tylenol causes autism" narrative is a lot messier than a simple soundbite.
The Day the FDA Changed Its Tune
It happened on September 22, 2025. Trump and RFK Jr. announced that the FDA would be notifying physicians that acetaminophen use during pregnancy "can be associated with a very increased risk of autism." Trump didn't mince words. He basically told women that unless they had a fever so high they couldn't stand it, they should avoid the drug entirely.
"Ideally, a woman won't take Tylenol," he said.
This wasn't just a random comment. It was a coordinated policy shift. The administration pushed for new safety labels and a public service campaign. They pointed to studies from places like Harvard and Johns Hopkins that showed an "association" between the drug and neurodevelopmental issues.
But here’s the thing. Association isn't the same as a cause.
Honestly, the medical community's reaction was somewhere between "mildly annoyed" and "completely terrified." The American College of Obstetricians and Gynecologists (ACOG) came out almost immediately. They said there’s no clear evidence proving a direct link. They were worried that women would stop treating fevers, and we know for a fact that a high fever during pregnancy can actually damage a developing brain.
Why the Science Is So Confusing
So, why did Trump say it? He wasn't just making it up out of thin air, even if he was stretching the truth to its breaking point. There have been dozens of studies—like the 2020 JAMA Psychiatry paper—that found kids whose moms took a lot of Tylenol were more likely to be diagnosed with autism or ADHD.
It sounds scary. But science is a bit of a detective game.
A huge "gold standard" study published in The Lancet in early 2026—just recently, actually—looked at 2.5 million children. They used a "sibling control" method. This is basically the holy grail of this kind of research. They compared siblings where the mom took Tylenol during one pregnancy but not the other.
The result? The risk completely vanished.
Basically, the researchers figured out that it wasn't the Tylenol causing the autism. It was "familial confounding." That’s a fancy way of saying that the same genetic or environmental factors that might make a mom more likely to need Tylenol (like chronic pain or certain infections) were the same factors linked to autism. Once you accounted for the family's shared genes, the drug itself looked totally innocent.
The RFK Jr. Factor and "MAHA"
You can’t talk about Trump’s Tylenol comments without talking about Robert F. Kennedy Jr. and the "Make America Healthy Again" (MAHA) movement. This was their big opening salvo. They wanted to show they were "taking on" big pharma.

Kennedy has been vocal about "environmental toxins" for years. For him, Tylenol was a low-hanging fruit because of the ongoing multi-district litigation (MDL) where hundreds of families were already suing Tylenol’s maker, Kenvue.
- The Lawsuits: By late 2024, a judge had actually dismissed many of these suits because the scientific evidence wasn't strong enough.
- The Strategy: The Trump administration’s move basically gave those lawsuits a second life.
- The Message: It was about "restoring trust" by questioning the status quo.
Whether it restored trust or just created a massive amount of anxiety is still being debated in every PTA meeting in the country.
What Should You Actually Do?
If you're pregnant or planning to be, "toughing it out" might actually be the worst advice you could follow. Untreated pain causes stress, and untreated fevers can cause birth defects.
The consensus from the World Health Organization and major medical boards hasn't actually shifted, despite the White House pressers. They still say acetaminophen is the safest option available. It's certainly safer than Ibuprofen or Advil, which are known to cause heart and kidney issues in a fetus during the later stages of pregnancy.

Basically, the "Trump saying Tylenol causes autism" headlines were a mix of preliminary science and heavy-duty politics. Most experts still suggest using the lowest dose possible for the shortest amount of time.
Next Steps for Your Health
- Consult your OB-GYN: Do not change your medication regimen based on a press conference. Ask your doctor about the "sibling control" studies that debunk the causal link.
- Manage Fevers: If you run a fever over 100.4°F (38°C) while pregnant, the risk of the fever to the baby is generally considered much higher than the risk of a dose of Tylenol.
- Check the Label: While the administration pushed for new labels, read the current FDA-approved guidance which still lists acetaminophen as the primary pain reliever for pregnancy.
- Look at the Full Body of Evidence: Don't rely on a single study. Organizations like the Autism Science Foundation provide deep dives into why the "causality" hasn't been proven.
