Tylenol does not cause autism.
The recent âTylenol during pregnancy and autismâ paper thatâs being cited as proof isnât proof at all.
Read todayâs issue of ImmunoLogic:

In fact, the lead author, Baccarelli, had these exact claims tossed out of federal court in 2023 for having ZERO scientific merit when he was a paid âexpert witnessâ in lawsuits against Tylenol manufacturers & Walmart.
So he decided to repackage it and get it published in a journal to give it the appearance of legitimacy.
Even though the strongest studies â sibling studies â show NO relationship between autism and Tylenol use during pregnancy. Itâs a cherry-picked group of studies that weighs memory recall FAR more heavily than actual data.
THAT is the âstudyâ the Trump administration is using as âproofâ Tylenol causes autism. That is the paper theyâre using to add warning labels to acetaminophen. That is the paper that Trump based his dangerous â and wrong â medical advice on.
This is ACTUALLY the lawsuit pipeline used by a group of physicians with zero toxicology or biochemistry expertise who brand themselves as âenvironmental exposure expertsâ and get academic positions under that heading.
⢠Get paid to testify as an âexpertâ
⢠Publish weak observational science under an academic title
⢠Use the paper to get credibility for court or policy
This is the exact tactic RFK Jr. has built his career on â turning civil litigation against âchemicalsâ into a pseudoscience pipeline.
Worse? Now it isnât just lawyers and griftersâour federal health agencies are legitimizing it.
So as Trump, RFK Jr, and their MAHA allies are screaming about this âpaperâ as proof Tylenol causes autism, remember:
Itâs courtroom testimony that was tossed out for being garbage in 2023, now dressed up for PubMed.
And who is harmed? All of us. The public put at risk by fear, confusion, bad science, and dangerous policy.
