Tylenol Use during Pregnancy Linked to ADHD

View all
Jarod Cassidy4 years ago

According to the L.A. Times, a recent study has found that women who took drugs with the ingredient acetaminophen, like Tylenol and Excedrin, during pregnancy were roughly 40 percent (and up to 63 percent) more likely to have a child diagnosed with attention deficit hyperactivity disorder.

About the Acetaminophen/ADHD Link

  • Though pregnant women are regularly assured that taking acetaminophen is safe and will not cause harm to a developing fetus, data from a recent study suggests these claims may not be entirely true.
  • In fact, data suggests a significant increase in the probability of a child developing ADHD symptoms severe enough to require medication.
  • Researchers determined that on average, taking acetaminophen during pregnancy increased a child’s risk of developing ADHD by 40 percent, but in some scenarios – when the child’s mother took acetaminophen during the last two trimesters – that risk increased to 63 percent.
  • The study, which was published in the Journal of the American Medical Association Monday, analyzed data from 64,000 Danish mothers and their children and began gathering details on the mothers’ acetaminophen use well before any learning or behavior problems became evident.
  • While the study was unable to determine the cause/effect relationship behind acetaminophen and ADHD, the study was able to remove variables like environmental exposure.
