Overview

• President Donald Trump and Health Secretary Robert F. Kennedy Jr. urged limiting prenatal use of Tylenol and signaled changes to U.S. drug warnings, drawing immediate pushback from medical authorities.
• Trump escalated his claims by telling parents on social media not to give Tylenol to children for virtually any reason, a stance at odds with guidance from the American Academy of Pediatrics.
• The World Health Organization, the European Medicines Agency, and the FDA say associations reported in some studies do not establish causation and that recommendations on paracetamol use in pregnancy should remain unchanged when medically indicated.
• A 2024 JAMA analysis of nearly 2.5 million Swedish births, including sibling comparisons, found no increased risk of autism, ADHD, or intellectual disability with prenatal acetaminophen exposure, a result echoed by similar research in Japan.
• Clinicians and public‑health experts warn that discouraging paracetamol could leave fever and pain undertreated in pregnancy and urge clear communications from national ministries, with Peru’s experts calling for an official reassurance to prevent unwarranted alarm.
