WASHINGTON, January 19, 2026 – The persistent, and repeatedly debunked, claim linking acetaminophen-commonly known as Tylenol-to an increased risk of autism has once again been challenged by rigorous scientific research. A new systematic review and meta-analysis published in The Lancet adds to a growing body of evidence refuting the connection, originally popularized by Robert F. Kennedy Jr.
Debunking the Myth: Acetaminophen and Neurodevelopment
multiple studies confirm no causal link between acetaminophen use during pregnancy and autism or ADHD in children.
- A comprehensive review of existing data found no increased risk of autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD) associated with prenatal acetaminophen exposure.
- Researchers analyzed data from numerous studies, encompassing millions of participants, to reach their conclusions.
- The findings directly contradict claims made by robert F.Kennedy Jr. and others promoting the false link.
- Separate studies from multiple countries-including Pakistan-have also reinforced the safety of acetaminophen use during pregnancy.
- The latest research underscores the importance of relying on evidence-based details when making healthcare decisions.
Is Tylenol safe during pregnancy? According to the latest research, yes.A large-scale review published January 18, 2026, in The Lancet, examined prenatal exposure to acetaminophen and its potential impact on child neurodevelopment, finding no evidence to support a link to autism or ADHD.
The Science Behind the Findings
The systematic review and meta-analysis, encompassing data from multiple observational studies, analyzed the neurodevelopmental outcomes of children whose mothers used acetaminophen during pregnancy. The study’s robust methodology and conclusive findings were highlighted by both ScienceDaily (January 16, 2026) and The Avian Flu Diary (January 16, 2026), further reinforcing confidence in the results. This research provides reassurance regarding the safety of acetaminophen during pregnancy when used appropriately.
ScienceDaily reported January 16, 2026, on the major review, emphasizing the lack of risk for both autism and ADHD. The Avian Flu Diary also covered the Lancet publication on January 16, 2026, highlighting the study’s robust methodology and conclusive findings.
