Experts Confirm Safety of Acetaminophen During Pregnancy in Relation to Autism Risk
Leading experts confirm that acetaminophen use during pregnancy does not increase the risk of autism, supporting its safety when used as directed.
Recent research and reviews conducted by experts at the London School of Hygiene & Tropical Medicine (LSHTM) have provided reassurance regarding the safety of using acetaminophen, commonly known as paracetamol, during pregnancy. The findings indicate that taking acetaminophen in recommended doses does not increase the likelihood of autism spectrum disorder (ASD) in children.
This clarification comes after an announcement in the United States suggested a potential link between prenatal acetaminophen exposure and a higher risk of autism. However, independent scientists and health authorities worldwide, including the UK's Medicines and Healthcare products Regulatory Agency (MHRA), have stated that there is no credible evidence supporting this claim.
Experts like Laurie Tomlinson emphasized that, based on extensive assessments of medication risks over the past decade, acetaminophen remains a safe option for pain relief during pregnancy within recommended limits. She highlighted that observed associations in some studies often stem from confounding factors, such as genetic links between conditions like hypermobility and autism, rather than direct causation by the medication itself.
Professor Ian Douglas explained the complexities of researching medication effects, noting that many observational studies struggle to distinguish correlation from causation. For example, women taking acetaminophen might do so due to underlying health issues that could independently influence the child's development. The most rigorous research, including sibling comparison studies from Sweden, has not found evidence of increased autism risk linked to prenatal acetaminophen use.
These insights reassure both healthcare providers and expectant mothers, encouraging them to rely on credible, evidence-based information and consult medical professionals for guidance. The overarching message from the scientific community is that acetaminophen, when used appropriately, remains a safe medication during pregnancy.
