The World Health Organization (WHO) has cautioned against claims that paracetamol (acetaminophen) taken during pregnancy causes autism in children, stating that current scientific evidence does not support such a conclusion.
During a press briefing in Geneva, WHO spokesperson Tarik Jašarevic emphasized that while some observational studies hint at a possible link, larger and more recent research has failed to establish a consistent pattern.
“If the link were strong, it would emerge across multiple studies,” he noted.
He added that the agency continues to advise caution in the use of medicines during pregnancy, especially in the first trimester, and recommends they be used only when necessary and under medical supervision.
The European Medicines Agency (EMA) also disputed the claims, confirming that there is no new evidence to warrant a change in the current guidance for paracetamol use in pregnancy.
Health regulators in various countries, including Australia, have reaffirmed that paracetamol remains a safe option when used appropriately during pregnancy.
Autistic‑research experts and medical groups have criticized the remarks, warning that they may cause unnecessary fear and misinformation among expectant mothers.
The controversy began after U.S President Donald Trump suggested that using Tylenol during pregnancy could increase the risk of autism in children.
This followed previous claims linking vaccines to autism, claims that have been scientifically discredited.
Given the lack of conclusive evidence, many experts stress that untreated fever or pain during pregnancy may itself carry risks to the developing baby.
They advise that any medication during pregnancy should be used carefully, at the lowest effective dose and only when necessary.
