Paracetamol Use During Pregnancy: Study Finds No Increased Risk of Neurodevelopmental Disorders in Children
Using paracetamol during pregnancy has been a topic of concern regarding its potential impact on the neurodevelopment of children. A recent study conducted by researchers from City St George’s, University of London aimed to address these concerns by analyzing 43 existing studies on the subject. The study found that there is no increased risk of autism, attention-deficit hyperactivity disorder (ADHD), or intellectual disability among children when paracetamol is used during pregnancy.
The research team compared pregnancies where the mother had taken paracetamol to those where the drug was not used. By pooling the results of sibling comparison studies, which compared siblings born to the same mother with and without paracetamol exposure during pregnancy, the researchers were able to control for shared genetics, family environment, and parental characteristics. The analysis included data from over 262,000 children assessed for autism, 335,000 for ADHD, and 406,000 for intellectual disability.
Professor Asma Khalil, who led the study, emphasized that the findings suggest that any previously reported links between paracetamol use during pregnancy and neurodevelopmental disorders are likely due to genetic predisposition or other maternal factors such as fever or underlying pain, rather than a direct effect of the medication itself. The study reaffirms that paracetamol remains a safe option for pregnant women when taken as directed.
The quality of the studies included in the analysis was assessed using the Quality In Prognosis Studies (QUIPS) tool to evaluate the risk of bias. The lack of association between paracetamol use during pregnancy and the risk of autism, ADHD, or intellectual disabilities was consistent across studies deemed to be of high quality and those with a longer follow-up period of over five years. While the study had limitations in analyzing smaller subgroups based on trimester of paracetamol use, frequency of use, or the sex of the baby, the overall findings support the recommendations of major medical organizations worldwide.
In conclusion, the study provides reassurance to pregnant women that using paracetamol as directed is safe and does not increase the risk of neurodevelopmental disorders in children. The findings highlight the importance of addressing pain and fever during pregnancy to prevent potential risks associated with untreated maternal fever.
