Tylenol May Cause ADHD or Autism

A recent study shows that women who took Tylenol (acetaminophen) during pregnancy may have increased risk of the child developing autism or ADHD. Tylenol is one of the most popular medications taken during pregnancy and may be taken by up to two-thirds of pregnant mothers. It has previously been considered safe but doctors indicate that all medications may carry some risk when taken during pregnancy.

Women or family members of children whose mothers took Tylenol while pregnant and who were diagnosed with autism spectrum disorder or ADHD may be eligible for compensation and are considering Tylenol Autism and ADHD Lawsuits.

Recent Study Connects Maternal Tylenol Use to ADHD and Autism

A recently published study indicates that a woman’s use of Tylenol while pregnant may increase the risk for development of autism or ADHD in their child. The study, published by the European Journal of Epidemiology was performed by researchers at the University of Barcelona in Spain. It examined medical records of 73,881 mother-child pairs.

The study concluded that children born to women who had taken Tylenol during pregnancy were 21% more likely to develop Attention Deficit Hyperactivity Disorder (ADHD) and 19% more likely to develop Autism Spectrum Disorder (ASD) than children who were not exposed to prenatal Tylenol use. Increased risk of sub-clinical symptoms in children whose symptoms were not severe enough to warrant diagnosis was also increased in both sexes.

The link to ADHD and autism was greater in boys, though it also affected girls. Childhood use of Tylenol after birth did not affect the risk of ADHD or autism.

Prior Studies May Also Show Link

Prior studies had shown a possible risk, however these studies were considered to be less well-controlled. A prior Israel-based examination of medical records which analyzed seven separate studies, revealed a possible link to Tylenol use of 30% higher ADHD risk and 20% higher autism risk, however the studies were largely based on the memory of the mother.

One study, involving umbilical blood, also confirmed a link which demonstrated that higher acetaminophen levels correlated with a 2 to 3-fold higher risk of ADHD diagnosis, however the study was smaller and involved 996 mother-child pairs.

Researchers warn that warn that the evidence does not prove Tylenol causes autism or ADHD but only that it may increase the risk.

Tylenol Has Been Considered Safe During Pregnancy

Estimates show that Tylenol use may be as high as 60 to 70% during pregnancy as it has generally been considered safe. Tylenol or acetaminophen is one of the most common medications taken during pregnancy and is considered to be safer than other pain relievers such as ibuprofen or aspirin which have been linked to heart and blood vessel birth defects.

Tylenol has been listed as Pregnancy Category B which indicates that:

Either animal reproduction studies have not demonstrated a fetal risk but there are no controlled studies in pregnant women, or animal reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the first trimester (and there is no evidence of risk in later trimesters).

There are no pain relievers which are considered completely “safe” and classified as Category A.

ADHD and Autism Spectrum Disorder On the Rise

Autism Spectrum Disorder (ASD)

Autism is one of the fastest-growing developmental disorders and affects over 1 in 59 children but this may be due to increased diagnosis rather than increased occurrence. Children are said to be on the “spectrum” which indicates a level of disability ranging from mild to severe. Autism Spectrum Disorder is characterized by:

  • social problems including difficulty communicating and interacting
  • repetitive behaviors
  • limited interests or activities
  • impairment for functioning in school, work, or other areas

ASD symptoms are usually recognized before age two and are not often considered controllable with diet or medications.

Attention Deficit Hyperactivity Disorder (ADHD)

ADHD is quite prevalent amongst children and affects as many as 5% or 1 in 20 children. It often occurs in combination with other disorders and begins to be apparent before age 12. Symptoms of ADHD include:

Symptoms of Attention Deficit

  • Lack of attention to detail
  • Trouble holding attention
  • Does not appear to listen
  • Fails to follow through
  • Trouble organizing
  • Avoids tasks which require attention over a period of time
  • Loses things
  • Easily distracted
  • Forgetful

Symptoms of Hyperactivity

  • Fidgets or squirms
  • Leaves seat frequently
  • Climbs and runs inappropriately
  • Cannot play quietly
  • Often “on the go” or “driven by a motor”
  • Talks excessively
  • Blurts out answer
  • Trouble waiting their turn
  • Interrupts frequently

In order for a child to be diagnosed with ADHD, six of nine symptoms from one or both lists must be present. In persons over age 17, five symptoms are required for diagnosis. Two-thirds of ADHD children are medicated for the disorder.

Tylenol ADHD or Autism Lawsuits

People whose children were diagnosed with ADHD or Autism after the mother took Tylenol during pregnancy may be considering lawsuits. Women who took Tylenol during pregnancy and whose children developed autism or ADHD and loved ones of those who were diagnosed with autism or ADHD and whose mothers took Tylenol during pregnancy may be eligible for compensation and should seek legal advice.

Notwithstanding claims relating to this product, the drug/medical device remains approved by the U.S. FDA.
