Overview

• President Trump urged pregnant women to avoid Tylenol and claimed it causes autism, while HHS and the FDA began steps toward new cautionary labeling and clinician advisories.
• The FDA told physicians that a causal relationship between prenatal acetaminophen use and autism has not been established, advising judicious use and discouraging routine treatment of low‑grade fevers.
• Major medical groups, including ACOG and SMFM, maintain acetaminophen remains an appropriate option in pregnancy when needed and caution that untreated fever and severe pain carry real maternal‑fetal risks.
• Scientists whose studies were cited by the administration say their work is being misinterpreted, noting the evidence is observational and that stronger sibling‑comparison research has not found a causal link.
• The administration’s promotion of leucovorin as an autism intervention faces skepticism due to limited data, and reporting highlights ties between Kennedy‑aligned advocates and supplement vendors marketing alternatives.
