Health and Human Services Secretary Robert F. Kennedy Jr<\/a>. is preparing a report that will allegedly claim a link between prenatal Tylenol (acetaminophen) use and autism, but current evidence does not support a causal relationship<\/a>, and major medical groups continue to recommend prudent acetaminophen use in pregnancy when indicated; meanwhile, Tylenol parent Kenvue\u2019s shares sold off sharply following the reports and remain volatile.<\/p>\n

What\u2019s in the planned report<\/p>\n

Multiple outlets report that the forthcoming<\/a> HHS autism report led by Robert F. Kennedy Jr. is expected to suggest that acetaminophen use in pregnancy is linked to autism and to highlight low folate levels, while pointing to folinic acid (leucovorin) as a potential way to reduce symptoms for some individuals with autism, according to people familiar with the draft cited by the Wall Street Journal<\/a>, which was first to report the news.<\/p>\n

HHS has said conclusions should not be assumed until the final report is released, and Kenvue has stated it has continually reviewed the science and sees no causal link between acetaminophen use during pregnancy and autism.<\/p>\n

Past claims about autism<\/p>\n

Fortune Well has contextualized RFK Jr.\u2019s broader claims <\/a>by reporting his focus on \u201cenvironmental toxins\u201d as key drivers of rising autism diagnoses, framing his assertions amid scientific uncertainty on specific non-genetic causes.<\/p>\n

Fortune Well also scrutinized RFK Jr.\u2019s earlier \u201cMAHA report,\u201d reporting that it cited nonexistent<\/a> or misinterpreted studies, signaling concerns about rigor and interpretation likely to shape reception of any new claims about acetaminophen.<\/p>\n

What the science says<\/p>\n

A very large 2024 JAMA study<\/a> of nearly 2.5 million Swedish children, using sibling-control analyses to account for familial confounding, found no association between prenatal acetaminophen exposure and diagnoses of autism, ADHD, or intellectual disability, a finding also summarized by NIH and advocacy groups.<\/p>\n

Conventional adjusted models often show small associations, but these are likely explained by unmeasured factors; in the JAMA study, the slight risk elevations disappeared in sibling analyses, while a prior meta-analysis without sibling controls reported ~19% higher odds for autism symptoms and ~21% for ADHD symptoms, illustrating how confounding can influence results.<\/p>\n

Major professional societies (ACOG and SMFM) continue to recommend acetaminophen as a first-line option for pain and fever in pregnancy when medically indicated, at the lowest effective dose for the shortest necessary time, and they do not advise changing practice based on current evidence.<\/p>\n

A 2021 \u201cprecautionary\u201d consensus statement urged caution with acetaminophen in pregnancy, but ACOG and other groups responded that the evidence for causality is weak and does not justify altering clinical guidance, underscoring the difference between association signals and proof of cause.<\/p>\n

Kenvue stock reaction<\/p>\n

Reports that RFK Jr.\u2019s upcoming HHS document will tie Tylenol in pregnancy to autism triggered a sharp selloff in Kenvue shares, with coverage noting declines of more than 6% intraday and a notably severe session for the stock<\/a> when it fell over 14% before paring losses.<\/p>\n

Additional outlets highlighted that Kenvue was among the market\u2019s most active movers as the news spread, and global coverage described the company\u2019s stock as \u201chit\u201d following the report chatter.<\/p>\n

Recent trading data show wide intraday swings and heavy volume in the aftermath, with a day\u2019s range that captured a deep drop and partial recovery, underscoring ongoing volatility rather than a settled trend.<\/p>\n

The planned report is expected to assert an acetaminophen\u2013autism link, but the strongest recent evidence does not support causation, and leading medical bodies still endorse careful, indicated use of acetaminophen in pregnancy; Kenvue\u2019s stock has been under pressure amid the headlines and remains\u00a0volatile.<\/p>\n
