Acetaminophen Use During Pregnancy and Neurodevelopmental Risks
Table of Contents
A complete review of existing research indicates that acetaminophen use during pregnancy is not associated with an increased risk of autism, attention-deficit hyperactivity disorder (ADHD), or intellectual disability in children. This finding, published January 16, 2024, in The Lancet Obstetrics, Gynaecology & Women’s Health, represents the most extensive analysis of the topic to date.
Study Methodology and Scope
Researchers at City, University of London, conducted a systematic review and meta-analysis of 43 previously published studies to assess the potential link between acetaminophen exposure in utero and neurodevelopmental outcomes. The team aimed to determine if there was a statistically notable correlation between the pain reliever and these conditions.
According to the study published in the Lancet Obstetrics & Gynaecology, the meta-analysis included data from cohort studies and case-control studies.
Key Findings and Risk Assessment
The analysis found no consistent evidence to support a causal relationship between acetaminophen use during pregnancy and an elevated risk of autism, ADHD, or intellectual disability. Researchers noted that while some individual studies had suggested a possible association,these findings were not replicated across the broader dataset.
Specifically,the study found no statistically significant increased risk of autism (pooled odds ratio 0.97, 95% confidence interval 0.88-1.07), ADHD (pooled odds ratio 1.03, 95% confidence interval 0.92-1.15), or intellectual disability (pooled odds ratio 1.01, 95% confidence interval 0.89-1.14). these results were adjusted for potential confounding factors.
expert Commentary and Context
The researchers emphasize that this review provides reassuring evidence for pregnant individuals who may need to use acetaminophen for pain or fever relief. However, they also acknowledge the importance of using the lowest effective dose for the shortest duration necessary.
Dr. Ruth Blackburn, lead author of the study from City, University of london, stated in a City, University of London news release, “Our findings suggest that women should not be unduly concerned about using acetaminophen during pregnancy. It remains an vital medication for managing pain and fever, and avoiding these conditions is also important for a healthy pregnancy.”
