Misinformation on TikTok linking acetaminophen use during pregnancy with autism surged following a 9/2025 FDA announcement ([see story](see%20story)) on the issue, with misleading videos attracting disproportionate attention, according to [research](https://www.eurekalert.org/news-releases/1145255?ref=fdaweb.com) presented at the American Academy of Pediatrics' 2026 National Conference & Exhibition.

Researchers analyzed 53 TikTok videos posted between September and November 2025 following FDA's announcement regarding a labeling change for acetaminophen products such as Tylenol. About 53% of the videos contained information consistent with available evidence, while 28% contained outright misinformation, the research found.

Despite representing a minority of the videos, misinformation accounted for more than half of total views, researchers reported. One misleading video received 10.3 million views, representing 36.6% of all exposure among the videos analyzed.

Nearly three-quarters of the videos containing misinformation were produced by influencers rather than medical professionals.

“Our results indicate that TikTok’s algorithm amplified low-quality, conspiracy-framed videos containing misinformation on a very sensitive health topic,” said **Shivani Srivastava**, a medical student at Rutgers School of Medicine.

Srivastava said evidence-based videos explained the lack of causal evidence linking prenatal acetaminophen exposure with autism but received substantially less exposure than the misinformation.
