New York, NY – August 21, 2025 – A groundbreaking study published August 14 in BMC Environmental Health suggests a potential connection between acetaminophen use during pregnancy and an elevated risk of neurodevelopmental disorders in children, including autism spectrum disorder and attention-deficit/hyperactivity disorder (ADHD). Researchers at the Icahn School of Medicine at Mount Sinai conducted the analysis, which challenges long-held beliefs about the safety of the common pain reliever for expectant mothers.
The Widely Used Medication Under Scrutiny
Acetaminophen, known as paracetamol outside of the United States and Canada, and commonly sold under the brand name Tylenol®, is the most frequently used over-the-counter medication for pain and fever reduction during pregnancy. More than half of all pregnant women globally rely on it for managing discomfort. Until recently, acetaminophen was generally considered the safest option available. This new research, however, prompts a critical reevaluation of that assumption.
Rigorous Methodology Reveals Potential Risks
The Mount Sinai team analyzed data from 46 studies, encompassing over 100,000 participants from diverse countries.Their examination employed the Navigation Guide Systematic Review methodology,a gold-standard approach for evaluating environmental health data. This method meticulously assesses each study for potential biases, such as selective reporting or incomplete information, and determines the overall strength and quality of the evidence.
Did You Know?
The Navigation Guide methodology is increasingly used to assess the reliability of environmental health studies, providing a more nuanced understanding of potential risks.
Key Findings and Expert Commentary
“Higher-quality studies consistently demonstrated a link between prenatal acetaminophen exposure and increased risks of both autism and ADHD,” explained Dr. Diddier Prada, Assistant Professor of Population Health Science and Policy, and Environmental Medicine and Climate Science at the icahn School of Medicine at Mount Sinai. “Considering the widespread use of this medication,even a modest increase in risk carries important public health implications.”
The research delves into potential biological mechanisms that could explain this association. Acetaminophen is known to cross the placental barrier, possibly inducing oxidative stress, disrupting hormonal balance, and causing epigenetic alterations that may interfere with the developing fetal brain.
understanding the Nuances of the Research
It’s crucial to note that the study does not definitively prove that acetaminophen causes neurodevelopmental disorders. Though, the findings substantially strengthen the evidence suggesting a connection and raise critically important questions about current clinical practices.The researchers emphasize the need for a more cautious approach to acetaminophen use during pregnancy.

Recommendations and Future Directions
The research team recommends cautious, time-limited use of acetaminophen during pregnancy, always under the guidance of a healthcare professional. They also advocate for updated clinical guidelines that carefully balance the benefits and risks of the medication. Further research is essential to confirm these findings and to identify safer alternatives for managing pain and fever in expectant mothers.
Pro Tip:
Always discuss all medications, including over-the-counter drugs, with your doctor during pregnancy.
“Pregnant women should not discontinue medication without consulting their physicians,” Dr. Prada stressed. “Untreated pain or fever can also pose risks to the developing baby. Our study underscores the importance of a collaborative discussion with healthcare providers to determine the safest course of action, and to explore non-pharmacological options whenever feasible.”
Given the rising global rates of autism and ADHD, these findings have far-reaching implications for public health policy, clinical practice, and patient education. The study also highlights the urgent need for pharmaceutical companies to prioritize the progress of safer pain relief options for pregnant women.
The collaborative research effort involved contributions from the University of California, Los Angeles; University of Massachusetts Lowell; and Harvard T.H. Chan School of Public Health.
Funding for this study was provided by the National Cancer Institute (U54CA267776), the National Institute of Environmental Health Sciences (R35ES031688), and the National Institute on Aging (U01AG088684).
What steps can healthcare providers take to better advise pregnant patients about pain management? How might pharmaceutical innovation address the need for safer alternatives to acetaminophen during pregnancy?
Acetaminophen and Pregnancy: A Growing Body of Research
Concerns regarding the potential risks of acetaminophen use during pregnancy have been gradually mounting over the past decade. Early studies hinted at possible associations with asthma and other developmental issues. This latest research, utilizing a highly rigorous methodology, adds considerable weight to the growing body of evidence suggesting a need for caution. The increasing prevalence of neurodevelopmental disorders worldwide further underscores the importance of investigating potential environmental factors, including medication exposure during critical periods of development.
Frequently Asked questions About Acetaminophen and Pregnancy
- Q: Is acetaminophen completely unsafe to use during pregnancy?
A: No, but this research suggests caution and a discussion with your doctor is crucial. Untreated pain or fever can also be harmful.
- Q: What are the potential biological mechanisms linking acetaminophen to neurodevelopmental disorders?
A: Acetaminophen may cause oxidative stress, disrupt hormones, and induce epigenetic changes affecting fetal brain development.
- Q: What is the Navigation Guide methodology?
A: It’s a gold-standard framework for evaluating environmental health data, assessing study quality and potential biases.
- Q: Should pregnant women stop taking acetaminophen instantly?
A: No. Consult your doctor before stopping any medication.
- Q: Are there safer alternatives to acetaminophen for pain relief during pregnancy?
A: Discuss non-drug options and alternative medications with your healthcare provider.
