Tylenol During Pregnancy Linked to Higher ADHD Risk
25 February 2014 5:15 pm
The ubiquitous pain- and fever-reducing medication acetaminophen (Tylenol) may increase risk of attention deficit hyperactivity disorder, or ADHD, in children whose mothers use the drug while pregnant, Forbes reports. Scientists tracked more than 64,000 families in the Danish National Birth Cohort and found that children whose mothers used the drug frequently had a 30% higher risk of an ADHD diagnosis. Although the study, published yesterday in JAMA Pediatrics, suggests some cause for concern, the authors emphasize that it is just a correlational study with no clear mechanism for harm and is too preliminary to guide recommendations for pregnant women.
