He cited a recent paper which suggests children may be more likely to develop autism if exposed to paracetamol during pregnancy, although this link is hotly disputed by scientists. He reacted strongly to the claims, saying that “rigorous research” has found that paracetamol or Tylenol did not have a link to autism. But he said that reports suggesting using paracetamol during pregnancy may constitute a risk factor for autism spectrum traits were “incorrect”. “Paracetamol has been well-studied in pregnancy, and there is no good evidence that it harms the unborn baby,” she said. Even the widely cited link between maternal folate receptor antibodies and neural tube defects has been challenged by follow-up studies.
