Acetaminophen Use During Pregnancy and Neurodevelopmental Disorders: A Potential Link, but More Research Is Needed

This review found a possible association between taking acetaminophen during pregnancy and an increased risk of neurodevelopmental disorders (NDDs) like ADHD and autism in children. However, the evidence comes mainly from observational studies, which can't prove cause-and-effect, and the review acknowledges limitations and potential residual confounding. While cautious acetaminophen use is advised, the authors emphasize the need to balance this with risks of untreated fever/pain and call for research into safer alternatives.

Explain Like I'm Five

Studies suggest that taking acetaminophen during pregnancy might be linked to a slightly higher chance of kids having problems like ADHD and autism. More research is needed to confirm this and explore safer alternatives.

Possible Conflicts of Interest

Dr. Baccarelli served as an expert witness for the plaintiff's legal team in related litigation. This involvement may be perceived as a conflict of interest, although he states efforts to maintain scientific integrity and objectivity.

Identified Limitations

Observational Studies Limitations
Most studies were observational; limitations in sibling-controlled studies; no definitive causation.
Recall Bias
Potential for recall bias and unmeasured confounding.
Heterogeneity
Heterogeneity in exposure assessment, outcomes, and confounders.
Causality
Limited ability to definitively establish causality
Maternal Self-Reporting
Reliance on maternal self-reports for medication data. Reliance on maternal self-reports for child ADHD assessment.
Parental Report Only
Some analyses relied on parental report only for NDD diagnosis

Rating Explanation

This systematic review uses a robust methodology (Navigation Guide) and includes many relevant studies, suggesting an association between prenatal acetaminophen exposure and NDDs. However, it is limited by its reliance on observational data, which cannot definitively establish causality. Also, significant heterogeneity prevented meta-analysis, the existence of contradicting findings and sibling control analyses require cautious interpretation. Finally, the identified COI raises concerns.
