After a 22 September press conference by Health Secretary Robert F. Kennedy Jr. and President Trump, more than one-third of Americans said Tylenol could cause autism.
One study found emergency-room orders for Tylenol among pregnant women fell 10%, with no change among non-pregnant women, suggesting the claims altered medical behaviour as well as public opinion.
The article says this reversal threatens years of neurodiversity gains, revives language framing autism as a disease, and coincides with federal autism bodies being populated by officials holding that view.
Amid conflicting government claims and scientific debate over Tylenol, how can expectant parents make informed health decisions for their children?
As rival committees steer autism research, will the community be helped or harmed by a fractured scientific agenda?

Debunking the Tylenol-Autism Link: Evidence from 3.5 Million Children and the Impact of Misinformation
Overview
In April 2026, HHS Secretary Robert F. Kennedy Jr. publicly denounced a large Danish study that found no link between prenatal acetaminophen use and autism, calling it fraudulent. This outburst, building on his ongoing promotion of the Tylenol-autism theory since September 2025, triggered swift scientific rebuttals defending the study, renewed market turmoil for Tylenol's manufacturer, and prompted the FDA to begin changing acetaminophen safety labels. These events fueled widespread media attention and contributed to declining public trust in health agencies. Observational data showed a temporary drop in acetaminophen use among pregnant women following these controversies, highlighting the real-world impact of misinformation from influential figures.
