When former President Donald Trump suggested this week that pregnant women should be cautious about taking Tylenol, it sparked confusion and worry among many parents. He claimed that the use of Tylenol, which contains acetaminophen, could be linked to autism in children. But what exactly is Tylenol, and what do medical experts say about this claim?

What is Tylenol and how is it used

Tylenol is one of the most common over-the-counter pain relievers in the United States. Its active ingredient is acetaminophen, also known as paracetamol in other parts of the world.

You have probably used Tylenol or a store-brand version to treat:

  • Headaches
  • Fever
  • Muscle aches
  • Minor pain during pregnancy, since it is often recommended as safer than other pain medications like ibuprofen

Because of its wide use and accessibility, Tylenol has become a household name. It is also one of the most frequently recommended pain relievers for pregnant women.

Why Trump linked Tylenol to autism

During his remarks, Trump urged pregnant women to “tough it out” and limit their Tylenol use, suggesting a link between the drug and autism. His comments touched a nerve because they followed years of ongoing debates about what might contribute to autism spectrum disorder.

Autism is a complex neurodevelopmental condition with more than 100 genes linked to it. While some studies have observed a possible association between acetaminophen use during pregnancy and autism, most experts stress that association does not mean causation.

As the Food and Drug Administration (FDA) explained: “While an association between acetaminophen and autism has been described in many studies, a causal relationship has not been established and there are contrary studies in the scientific literature.”

What health experts are saying

Doctors and researchers quickly responded to Trump’s claims, warning that they may cause unnecessary fear for expectant mothers.

  • Dr. Rachel Follmer, a developmental and behavioral pediatrician at Ann & Robert H. Lurie Children’s Hospital of Chicago, said: “It really puts women and mothers and medical providers in this really challenging situation because women are now being told differing stories from different individuals.”
  • The Society for Maternal-Fetal Medicine has also warned that untreated fever or pain during pregnancy can be dangerous, sometimes increasing the risk of miscarriage, birth defects, and premature birth.

In short, medical experts agree that avoiding Tylenol altogether without medical guidance could create more risks than it prevents.

The history of blaming mothers for autism

Trump’s Tylenol comments echo a long history of looking for a single cause of autism and often pointing fingers at mothers.

  • In the 1940s, mothers were blamed under the “refrigerator mom” theory, which wrongly suggested autism was caused by emotionally distant parenting.
  • In the late 1990s, vaccines were wrongly blamed after a discredited study claimed a link between autism and the MMR vaccine.

As Martine Lappé, a sociology professor at California Polytechnic State University, explained: “We really have a long history of blaming mothers in this country, and we’re seeing that reinforced through the narratives around autism’s causes right now.”

What parents should keep in mind

If you are pregnant or planning to become pregnant, it is normal to feel anxious after hearing claims like this. But here are some key points to remember:

  • Autism is not caused by a single factor. It is also dependent on a combination of genetics and other complex conditions.
  • Tylenol remains one of the most commonly recommended pain relievers during pregnancy.
  • Always talk to your healthcare provider before making changes to your medication.

Medical scholars argue that focusing on single causes becomes a distraction from more important matters such as healthcare access, family support, and research that truly benefits autistic people.
