Maybe Tylenol is a correlate for illness and inflammation, rather than a cause of autism.
Then why isn't aspirin or Ibuprofen?
Tylenol doesn’t affect inflammation. That’s ibuprofen.
I did some research because I’m on blood thinners and Tylenol (acetaminophen) is one of the few non-opioid substances I can take for pain.
It turns out that, other than potential addiction, acetaminophen does far more damage to your body/liver than the opioids do.
