It happened during a press conference that felt more like a medical intervention than a political briefing. On September 22, 2025, Donald Trump stood at the White House and basically told the world that a medicine cabinet staple—Tylenol—was "not good." He didn't just suggest being careful. He said, "Don't take Tylenol." He was flanked by Health and Human Services Secretary Robert F. Kennedy Jr. and Dr. Mehmet Oz. The scene was surreal. If you’ve been following the news in early 2026, you know this single moment has completely upended how people think about their headaches and fevers.
Why is he saying this?
The short answer is autism. Specifically, a perceived link between prenatal exposure to acetaminophen (the active ingredient in Tylenol) and neurodevelopmental disorders. Trump claimed that the FDA would be updating drug labels to discourage use during pregnancy. He even went so far as to suggest that countries with less access to Tylenol, like Cuba, have "virtually no autism." That's a massive claim. It's also one that has set the medical community on fire.
Why is Trump saying don't take Tylenol during pregnancy?
Trump’s stance isn’t coming out of thin air, but it’s leaning heavily on a specific, controversial slice of science. The administration points to a handful of observational studies. One notable 2025 study analyzed 46 different papers and found a "correlation" between acetaminophen use in the womb and higher rates of ADHD and autism.
Correlation isn't causation. That's the mantra you'll hear from every doctor from the Mayo Clinic to your local GP.

The Trump administration, led by RFK Jr., is pushing what they call the "precautionary principle." Basically, if there's even a whiff of risk, stop using it. RFK Jr. has been vocal about his belief that we are in the middle of an "autism epidemic" and that we need to look at every environmental factor. During a cabinet meeting in October 2025, he admitted the evidence wasn't "dispositive" or proof yet, but said they were working to "make the proof."
Honestly, it’s a weird way to handle public health. Usually, you wait for the proof before you tell millions of pregnant women to stop taking the only painkiller doctors have called "safe" for decades.
The Science vs. The Rhetoric
While Trump says "it's not good," the actual medical data is a lot more messy. A massive Swedish study published in 2024 looked at 2.4 million children over 25 years. They compared siblings where one was exposed to Tylenol in the womb and the other wasn't. The result? No increased risk of autism or ADHD.
This is what scientists call a "sibling-controlled" study. It’s powerful because it accounts for genetics and home environment. If the drug were the cause, the exposed sibling should show higher rates. They didn't.

Medical groups like the American College of Obstetricians and Gynecologists (ACOG) were quick to call the administration's warnings "irresponsible." Their logic is simple: fevers are dangerous. If a pregnant woman has a high fever and refuses Tylenol because of Trump’s comments, that fever itself could cause birth defects or miscarriage.
The RFK Jr. Influence and "TrumpRx"
You can't talk about why Trump is saying don't take Tylenol without talking about RFK Jr. Since taking over HHS, Kennedy has pivoted the department toward investigating what he calls "root causes" of chronic illness. He’s linked Tylenol to everything from autism to issues following circumcision.
Trump has also rolled out "TrumpRx," a platform meant to lower drug costs. It’s a bit of a mixed message. On one hand, the administration is making deals with big pharma companies like AbbVie and Pfizer to lower prices on insulin and migraine meds. On the other, they’re telling you to stay away from the most common over-the-counter drug on the market.
What the FDA is actually doing
Despite Trump's "don't take it" rhetoric, the FDA’s official stance is a bit more guarded. They did issue a letter to physicians, but it was nuanced. It suggested "minimizing" use for "routine low-grade fevers." It didn't say "ban it."

The FDA letter admitted that:
- An association has been described in some studies.
- No causal relationship has been established.
- Acetaminophen remains the safest option compared to aspirin or ibuprofen (which are linked to heart and kidney issues in fetuses).
The Chaos in the Doctor's Office
The real-world impact of this has been a lot of confused parents. Some moms have taken to TikTok, filming themselves taking Tylenol as a form of protest—something RFK Jr. called "pathological." Meanwhile, other parents are terrified that they might have "caused" their child's autism by taking a pill for a headache three years ago.
It’s a heavy burden to place on parents based on "opinion," which is what Trump himself admitted he was giving during a September press conference. "I'm not a doctor, but I'm giving my opinion," he said.
Doctors are worried that we’re heading back to a time when pregnant women just had to suffer through pain, or worse, use "natural" remedies that haven't been tested at all.
Actionable Advice for Navigating the Tylenol Debate
If you're staring at a bottle of Tylenol and wondering if the President knows something your doctor doesn't, here’s how to handle it based on current 2026 clinical guidance.
- Consult your OB-GYN, not a press release. Medical professionals have access to the full breadth of peer-reviewed data. They can assess your specific health risks.
- Treat high fevers immediately. A temperature over 102°F (38.9°C) during pregnancy is a known risk for fetal development. Most experts still agree that the risk of the fever far outweighs the theoretical risk of the medication.
- Use the lowest dose for the shortest time. This has always been the gold standard for any medication during pregnancy. If you have a mild headache, try hydration or rest first. If you need medicine, take one dose, not the whole bottle over a week.
- Ignore the "Cuba" comparisons. Global autism rates are heavily influenced by how different countries screen and diagnose the condition. Low reported rates in other countries often reflect a lack of diagnostic resources, not a lack of the condition itself.
- Watch for the new labels. The FDA is expected to finalize the new warning labels by mid-2026. These will likely focus on "prudent use" rather than an outright warning against the drug.
The debate over why Trump is saying don't take Tylenol isn't going away soon. It’s part of a much larger shift in how the current administration views federal health agencies and established medical consensus. For now, the safest bet is to rely on your personal healthcare provider and the weight of the existing scientific evidence, which still largely views occasional acetaminophen use as the safest choice for pain relief during pregnancy.
