Gov’t says no link between paracetamol use in pregnancy and autism

The statement was issued in response to a media enquiry about acetaminophen use.

The Department of Health (DH) announced that there is no link between paracetamol use during pregnancy and autism or attention deficit/hyperactivity disorder.

The statement was made in response to a media enquiry regarding the use of pharmaceutical products containing acetaminophen, also known as paracetamol, by pregnant women.

The DH added that preventing mother-to-child transmission of hepatitis B through immunisation remains central to Hong Kong’s hepatitis B control strategy. It said it would continue to monitor scientific evidence and developments both locally and internationally.

Moreover, the agency noted pregnant women should exercise caution when taking medicines, particularly in the first trimester. Before using any medicines, they should consult healthcare professionals or follow medical advice.

The World Health Organization stated that there is insufficient scientific evidence to conclude that paracetamol use in pregnancy causes autism or other neurodevelopmental disorders.

Regulatory authorities in the European Union, the UK, Australia, and Canada have also said paracetamol remains a treatment option for pregnant women when clinically indicated and under medical advice.

There are about 700 registered medicines in Hong Kong containing paracetamol. No reports have been received linking paracetamol use during pregnancy to autism in children.
