Autism is a complicated neurodevelopmental disorder that affects social interaction and communication. It is usually discovered in childhood and can cause a wide range of symptoms, including difficulty with communication, repetitive behaviors, and sensory processing issues. There is no known cure for autism, and treatment usually involves therapies to help people living with autism manage their symptoms and improve their quality of life.

Over the years, there has been much debate and controversy surrounding the potential causes of autism. While there is no single known cause of autism, research has suggested that both genetic and environmental factors may play a role in the development of the disorder. One potential environmental factor that has received a lot of attention is the use of Tylenol (also known as acetaminophen) during pregnancy.

What is Tylenol and How is it Used During Pregnancy?

Tylenol is a pain medication that is usually nondescript but is also available by prescription. Tylenol is often the first choice for pain relief during pregnancy because it used to be considered safe for use in pregnant women until recent studies began to prove otherwise. 

The potential link between Tylenol use during pregnancy and autism has been the subject of much research and debate. While some studies have suggested a potential link between the two, others have found no association.

What Does the Research Say?

A study released in the European Journal of Epidemiology in May 2021 discovered that kids subjected to acetaminophen before conception had a 19% increased risk of autism and a 21% increased risk of ADHD symptoms.

Acetaminophen levels in newly born umbilical cord blood were measured in a different Johns Hopkins study released in JAMA Psychiatry in 2019. According to the study, kids with the highest concentration of the painkiller in their umbilical cord had 2.86 times the chance of being diagnosed with ADHD and 3.62 times the chance of having an ASD.

What Does This Mean for Expecting Mothers?

Given the startling results of these studies, it is easy to say that Tylenol use during pregnancy is associated with an increased risk of autism in children. Hence, it is important for expecting mothers to discuss these concerns with their healthcare provider for proper guidance. 

While Tylenol at this point may be considered unsafe for use in pregnant women, it is only important that pregnant women use medications with caution and only as directed. If you are pregnant and experiencing pain or discomfort, it is always best to consult with your healthcare provider before taking any medication.

It is also important to remember that Tylenol is not the only potential risk factor for the development of autism. Other potential risk factors for autism include advanced parental age, certain medical conditions during pregnancy, and a family history of autism.

In place of these facts, several lawsuits have been filed against manufacturers of Tylenol, and there have been several recorded payouts made to victims. If you are considering taking up legal action, you can check out this list of “Tylenol autism lawyers near me.”


The potential link between Tylenol use during pregnancy and the development of autism in children is a complex and controversial topic. While some studies have suggested a potential link between the two, others have found no association. It is important for expecting mothers to discuss any concerns they may have with their doctors and to only use prescribed drugs. 

As we mentioned earlier, it’s also crucial to keep in mind that there are other possible causes of autism besides Tylenol and that more research is required to fully comprehend all contributing factors of this complicated and diverse disorder.
