Kenvue, which owns McNeil Consumer Healthcare, the maker of Tylenol, told The Journal, "We have continuously evaluated the science and continue to believe there is no causal link between acetaminophen use during pregnancy and autism."
Acetaminophen, the key drug in Tylenol, is available in a variety of other over-the-counter pain-killers.
The HHS report will include findings linking pregnant women's use of the painkiller to autism and also will suggest folinic acid as a means of decreasing autism symptoms, according to the Journal.
Folinic acid has already been reported as a possible treatment for autism.
Forbes has reached out to HHS and Kenvue for comment.
