Scientists find no link between Tylenol and autism, again, after Trump warning

A large-scale study involving over 120,000 sibling pairs found no evidence that prenatal acetaminophen (Tylenol) use increases autism or ADHD risk. Coverage highlights the study’s scale and methodology as key factors in its credibility, with outlets like *Science News* and *MedPage Today* emphasizing its alignment with prior meta-analyses. Major health and science publications—including *Seoul Economic Daily*, *SBS Australia*, and *Ars Technica*—are reporting the findings, framing them as a reassurance for pregnant women who may have avoided acetaminophen due to misinformation.

The study’s focus on sibling comparisons reduces confounding variables, strengthening its conclusions. Some reports note the timing coincides with renewed public scrutiny of prenatal medication safety, though no direct policy changes have been announced. Watch for potential updates on regulatory guidance or public health advisories, particularly in regions where acetaminophen warnings remain widespread.

Follow-up studies may explore other prenatal medications or factors, though today’s focus is on reinforcing the lack of evidence for this specific link. Media may also revisit the role of misinformation in shaping parental health decisions.
