The World Health Organisation (WHO) has dismissed widespread claims suggesting that taking acetaminophen (paracetamol) during pregnancy causes autism, stressing that there is no scientific proof to support such an association.
In a statement released on Wednesday, WHO explained that although extensive research—including large-scale studies—has been conducted over the past decade, no consistent evidence has emerged to establish a direct link.
“Extensive research has been undertaken over the past decade, including large-scale studies, looking into links between acetaminophen use during pregnancy and autism. At this time, no consistent association has been established,” WHO stated.
The health body advised pregnant women to only take medications under the guidance of qualified health professionals and to exercise particular caution during the first trimester.
WHO also reiterated that vaccines do not cause autism, noting that multiple high-quality studies across several countries have confirmed their safety. Childhood vaccines, including those containing thiomersal or aluminium, were declared safe, with earlier claims suggesting otherwise described as long discredited.
According to WHO, an estimated 62 million people worldwide—about 1 in every 127 individuals—live with autism spectrum disorder, a neurodevelopmental condition whose causes remain unclear but are believed to result from multiple factors.
The agency emphasised that immunisation programmes have saved at least 154 million lives over the past 50 years, protecting children, adolescents, and adults against 30 infectious diseases.
Autism and other neurodevelopmental disorders are expected to be a key focus at the fourth UN High-Level Meeting on Non-Communicable Diseases and Mental Health scheduled for Thursday, September 25.
“As a global community, we need to do more to understand the causes of autism and how best to care for and support autistic people and their families. WHO stands with people who are living with autism and their families, a dignified community entitled to evidence-based considerations free of stigma,” the statement concluded.
