Robert F. Kennedy Jr. on health: what the evidence says · JRE #2461
SUBJECT: HEALTH
Not a true/false call. Every claim is logged with its sources; read the exhibits below.
The studies that support Tylenol safety are very weak and they have huge holes in them. There's overwhelming science that says you shouldn't take it, particularly... during pregnancy, and particularly the last days of pregnancy.
What the evidence says 01 / RECORD
Kennedy claims "overwhelming science" shows acetaminophen use in pregnancy is unsafe and that studies supporting its safety are weak; the largest and most rigorous analysis to date points the other way. A 2024 JAMA study of 2,480,797 Swedish children used sibling-control methods to account for genetic and familial confounding, and found no association between acetaminophen use during pregnancy and children's risk of autism, ADHD, or intellectual disability once siblings discordant for exposure were compared, indicating that associations seen in earlier, less-controlled models were likely attributable to familial confounding rather than the drug itself. This does not support characterizing the evidence as "overwhelming" in the direction of harm, or the safety literature as uniformly weak; the balance of evidence is better described as mixed in uncontrolled observational studies but reassuring in the most rigorous controlled analysis.
