RFK Jr. report will link autism to Tylenol use during pregnancy

Health Secretary Kennedy plans to release a Department of Health and Human Services report this month, claiming Tylenol’s active ingredient, acetaminophen, used during pregnancy, may contribute to autism risk. The report cites low folate levels as a potential factor and suggests folinic acid to reduce autism symptoms.

Kenvue, Tylenol’s manufacturer, saw its stock plummet 16% after the report’s details emerged. “We have continuously evaluated the science and continue to believe there is no causal link between acetaminophen use during pregnancy and autism,” a Kenvue spokeswoman stated.

Prior studies on acetaminophen’s fetal development risks yield mixed results, with no definitive causal link established. The American College of Obstetricians and Gynecologists deems Tylenol safe for pregnant women, advising consultation with doctors.

The report, led by NIH director Bhattacharya, FDA Commissioner Makary, and CMS Director Oz, reviews existing research and lists other potential autism causes, calling for further study. Kennedy, long vocal on autism, promised in April, “By September we will know what has caused the autism epidemic.” Critics argue rigorous research requires years.

HHS will announce NIH autism research grants alongside the report. Its final form awaits completion, with no confirmed White House review.
