Lancet Review Finds No Link Between Paracetamol Use in Pregnancy and Autism, ADHD or Intellectual Disability

Emphasis on sibling comparisons with low‑bias studies indicates earlier signals were confounding, reinforcing existing guidance.

Overview

  • An international team reviewed 43 studies and meta‑analysed 17, reporting no clinically important association between prenatal paracetamol use and autism, ADHD or intellectual disability.
  • The meta‑analysis incorporated outcomes for roughly 262,852 children assessed for autism, 335,255 for ADHD and 406,681 for intellectual disability.
  • Researchers prioritized sibling‑comparison designs, low‑risk‑of‑bias cohorts and longer follow‑up to better account for genetics, family environment and maternal health.
  • The authors conclude previously reported links likely reflect factors such as genetic predisposition, maternal fever or underlying pain rather than a causal drug effect.
  • Clinicians are urged to continue recommending paracetamol as first‑line for pain or fever in pregnancy when used as directed, with experts warning that discouraging its use could cause harm; the findings rebut September warnings from the U.S. administration and contrast with an FDA label change while aligning with EMA statements.
