Is there a scientific link between Tylenol and autism?
The Trump autism announcement on September 22, 2025, sparked nationwide discussion and concern among parents, healthcare providers, and autism advocates. In a high-profile White House briefing, former President Donald Trump, alongside officials from the Department of Health and Human Services (HHS), addressed two groundbreaking but controversial topics: a possible link between acetaminophen and pregnancy and the risk of neurological conditions like autism and ADHD, and early research into leucovorin as a potential therapy for specific individuals with autism.
For families across Washington and the rest of the country, this news brings a mix of hope, confusion, and even fear. What does science say? How should expecting parents approach these findings? And what does this mean for families already navigating an autism diagnosis?
This blog by ABA Centers of Washington breaks down the key details, separates facts from speculation, and provides guidance for families seeking clarity and support.
Acetaminophen and Pregnancy: Why It’s Making Headlines
Acetaminophen, best known under the brand name Tylenol, has long been one of the few over-the-counter pain and fever medications considered safe during pregnancy. However, the Trump autism announcement highlighted growing research suggesting a potential association between frequent or high-dose acetaminophen use during pregnancy and an increased risk of developmental conditions such as autism and ADHD in children.
Shortly before the announcement, the FDA issued a statement acknowledging this evidence and initiating the process to update warning labels on acetaminophen products. According to FDA Commissioner Marty Makary, M.D., M.P.H.,
“The FDA is taking action to make parents and doctors aware of a considerable body of evidence about potential risks associated with acetaminophen. Even with this body of evidence, the choice still belongs with parents.”
The FDA emphasized that while there is enough data to warrant precautionary steps, this is not proof of causation. Pregnant women should not abruptly stop taking acetaminophen without speaking to their healthcare provider, as untreated high fevers and pain can also harm both the mother and baby.
What Research Really Shows
Studies over the past decade have explored the relationship between autism and pregnancy, explicitly focusing on maternal acetaminophen use. While some extensive observational studies have found a correlation, experts caution against misinterpreting these results:
- Association, not causation: Many studies show only a correlation. Other factors, such as genetics, maternal illness, or environmental conditions, may explain the connection.
- Mixed findings: Research from Sweden that compared siblings (where one pregnancy involved acetaminophen use and another didn’t) found the association weakened significantly when genetic and environmental factors were controlled.
- Dosage and timing matter: Occasional, low-dose use has not shown the same risk patterns as prolonged or high-dose use, but exact thresholds remain unclear.
In short, while the Trump autism announcement has brought this issue into the spotlight, the science is still evolving. Pregnant individuals should balance potential risks and benefits with their doctor’s guidance rather than relying solely on headlines.
Expert Reactions and Public Concerns
The White House briefing quickly became a flashpoint for debate. Some public health experts praised the administration for prioritizing transparency and pushing for more research funding. Others worried that framing the issue too firmly could lead to unnecessary fear and guilt among expecting parents.
Medical organizations, including the American College of Obstetricians and Gynecologists (ACOG), issued statements urging calm:
- Parents should not stop taking acetaminophen suddenly, especially if recommended by a physician.
- Always consult a qualified healthcare provider when making decisions about medication during pregnancy.
- The priority should remain evidence-based prenatal care, including regular screenings and developmental monitoring after birth.
Leucovorin: A Promising but Early-Stage Therapy
Beyond the discussion of acetaminophen and pregnancy, Trump autism announcement introduced another topic that sparked curiosity: leucovorin, a form of folinic acid.
Early studies suggest leucovorin may help improve:
- Speech and communication skills
- Social interactions
- Adaptive behaviors
However, experts stress that:
- Leucovorin is not a universal treatment for autism
- More large-scale, randomized clinical trials are needed before it can be widely recommended
While this research is exciting, it remains experimental, and families should be cautious about pursuing unapproved treatments without medical supervision.
How Families Can Navigate the News
Hearing about possible risks during pregnancy or experimental treatments can be overwhelming. Here are some steps families can take to stay informed and proactive:
- Talk to your doctor: If you are pregnant or planning to become pregnant, discuss any concerns about acetaminophen or other medications with your healthcare provider.
- Focus on early diagnosis: Regardless of potential causes, early identification of autism provides children with the best chance to thrive through proven interventions like ABA therapy.
3. Seek personalized support: Every family’s journey is unique. Accessing professional, evidence-based services is key to reducing stress and building a strong care plan.
