Medical Consensus Links Tylenol (Acetaminophen) to ASD/ADHD in Children

Hundreds of parents of children with ASD and/or ADHD have sued the makers of Tylenol and other acetaminophen-containing drugs. Their legal claims are based upon scientific evidence showing use of acetaminophen during pregnancy can cause neurodevelopment effects in children. These studies involve children whose mothers took acetaminophen during pregnancy and who were diagnosed with ASD or ADHD. The studies show use of acetaminophen in pregnancy increases the risk of a child developing ASD by up to 51% and of a child developing ADHD by up to 143%.

What is Acetaminophen?

McNeil Consumer Healthcare developed acetaminophen (also known as paracetamol)  in 1955 and sold it under the brand name Tylenol. Later generic manufacturers began making and selling acetaminophen under various brand names or store brands. 
Acetaminophen is the active ingredient in Tylenol and generic versions of the drug. It is commonly used for pain relief and/or fever. Acetaminophen can be purchased over-the-counter. It can be used alone in pain relieving and fever reducing medicines. It is also used in combination with one or more drugs in other medications – such as cough, cold, allergy and arthritis medicines.

Acetaminophen was not tested for safety during pregnancy.

Many people assume acetaminophen was tested for safety in pregnancy, but that is not true. McNeil (the original manufacturer) did not test acetaminophen for safety in pregnant women or young children before putting it on the market. 
Independent medical researchers who are not affiliated with the drug companies have studied acetaminophen. Their studies show acetaminophen use in pregnancy increases the risk of ASD and ADHD in children. Despite this research, the drug companies have never tested the safety of acetaminophen use in pregnant woman or young children or warned pregnant women of the neurodevelopmental risks associated with acetaminophen use during pregnancy – instead choosing profits over health and safety.

Medical consensus links prenatal Tylenol (acetaminophen) use to ASD and ADHD.

In December 2021, 91 clinicians, research scientists, and public health professionals from across the globe sounded the alarm about acetaminophen use in pregnancy. These doctors published a Consensus Statement in the prestigious journal Nature about the links between prenatal acetaminophen exposure and neurodevelopmental disorders. They noted an increasing number of studies – both experimental (studies in laboratory animals) and epidemiological (studies of children exposed to acetaminophen prenatally) – suggested the drug might alter fetal development and increase the risk of neurodevelopment disorders, such as ASD and ADHD.
