Kenvue Craters On Report RFK Jr To Link Autism To Tylenol Use In Pregnancy

The stock of Tylenol maker Kenvue is crashing after a WSJ report according to which Robert F. Kennedy Jr. plans to announce that pregnant women’s use of an over-the-counter pain medication is potentially linked to autism in a report that will also suggest a medicine derived from folate can be used to treat symptoms of the developmental disorder in some people.

The report, sourced to "people familiar" and expected this month from the Department of Health and Human Services, is likely to highlight low levels of folate, an important vitamin, and Tylenol - which has been mass produced since 1955 - taken during pregnancy as well as other potential causes of autism.

Kennedy’s department also plans to pinpoint a form of folate known as folinic acid, or leucovorin, the people said, as a way to decrease the symptoms of autism, which affected roughly one in 31 eight-year-olds in the U.S. in 2022.
