Excerpts from NIH:

Exposure to acetaminophen in the womb may increase a child’s risk for attention deficit/hyperactivity disorder and autism spectrum disorder, suggests a study funded by the National Institutes of Health and the Agency for Health Care Research and Quality. The study appears in JAMA Psychiatry.

Researchers analyzed data from the Boston Birth Cohort, a long-term study of factors influencing pregnancy and child development. They collected umbilical cord blood from 996 births and measured the amount of acetaminophen and two of its byproducts in each sample.

By the time the children were an average of 8.9 years, 25.8% had been diagnosed with ADHD only, 6.6% with ASD only and 4.2% with ADHD and ASD.

The researchers classified the amount of acetaminophen and its byproducts in the samples into thirds, from lowest to highest.

  • Compared to the lowest third, the middle third of exposure was associated with about 2.26 times the risk for ADHD.
  • The highest third of exposure was associated with 2.86 times the risk. Similarly, ASD risk was higher for those in the middle third (2.14 times) and highest third (3.62 times).

The U.S. Food and Drug Administration urges careful consideration before using any pain-relieving medication during pregnancy.
