Tylenol and Acetaminophen Lawsuit

Taking Acetaminophen While Pregnant May Increase the Risk of Autism

Use Linked to Autism During Pregnancy

An overwhelming body of scientific literature has found a link between ingestion of Tylenol or acetaminophen during the second and/or third trimester of pregnancy to the development of autism spectrum disorder (ASD).

What is Acetaminophen?

Acetaminophen is an active ingredient in over-the-counter (OTC) medications and prescription drugs, including Tylenol. It is a pain reliever for severe to moderate pain, as well as a fever reducer. Tylenol and Acetaminophen have been widely thought of as safe, and have been prescribed by medical professionals to pregnant women for pain relief and fever reduction.

Epidemiological Studies on Tylenol and/or Acetaminophen and Autism Risk

Over the past few years, a number of epidemiological studies have suggested a link between acetaminophen use during pregnancy and an increased risk of autism in children. These studies have sparked widespread concern among healthcare professionals and expectant mothers alike, leading to calls for stronger warning labels on acetaminophen products.

One of the most significant studies on this topic was published in the journal JAMA Pediatrics in 2016. The study, which included data from over 2,500 mother-child pairs, found that children whose mothers had taken acetaminophen during pregnancy were more likely to exhibit symptoms of autism or developmental delay by the age of three.

Another study published in the International Journal of Epidemiology in 2017 analyzed data from over 73,000 mother-child pairs and found a significant association between prenatal acetaminophen exposure and an increased risk of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in children.

In 2019, a study funded by NIH from Johns Hopkins analyzed umbilical cord blood samples from 996 births and found that exposure to acetaminophen increased a child’s risk for autism spectrum disorder.

The study found that babies with the highest acetaminophen levels in the cord blood were three times more likely to be on the autism spectrum compared to children with lower acetaminophen levels in their cord blood.
