Pregnancy often comes with a laundry list of do’s and don’ts, but one seemingly innocuous item – Tylenol, or acetaminophen – has recently faced scrutiny due to claims that its use during pregnancy could be linked to an increased risk of autism and attention deficit hyperactivity disorder (ADHD) in children.
As parents-to-be grapple with concerns, medical experts emphasize the need for a nuanced understanding of the available evidence and the broader context surrounding prenatal medication use.
Allegations of a Link to Autism and ADHD
Acetaminophen has long been considered a safe option for pain relief and fever reduction during pregnancy. Unlike nonsteroidal anti-inflammatory drugs (NSAIDs), which are generally not recommended for pregnant individuals, acetaminophen has been a go-to over-the-counter option for expectant mothers.
Doctors often prescribe Tylenol to alleviate pain and, crucially, reduce fever, which can pose serious risks to both the mother and the developing fetus.
Dr. Abdulla Al-Khan, Director of Maternal-Fetal Medicine and Surgery, highlights the importance of managing fever during pregnancy, as high temperatures can lead to complications such as seizures, preterm labor, and potential embryonic malformation.
The controversy surrounding acetaminophen use during pregnancy emerged in 2021 when a consensus statement in Nature Reviews Endocrinology suggested potential risks, including an increased likelihood of ADHD and autism.
Subsequently, over 400 product liability lawsuits have been filed against acetaminophen manufacturers, arguing that consumers, particularly pregnant individuals, should have been warned about these alleged risks.
While plaintiffs claim a connection, manufacturers argue that there is insufficient conclusive evidence to support these assertions. The matter is now before a U.S. District Court judge who will determine if the lawsuits have enough admissible scientific evidence to proceed.
Medical experts caution against drawing definitive conclusions based on the current evidence. Dr. David Hackney emphasizes the need for cautious consideration, given the historical association of epidemiologic findings with conditions like ADHD and autism, which later proved not to be causative.
Dr. Whitney Casares stresses the importance of scrutinizing facts and evidence when interpreting legal cases involving medication and potential adverse outcomes. Despite the attention these lawsuits attract, it’s crucial to avoid premature blame or exoneration without a thorough understanding of the available data.
The causes of autism spectrum disorder and ADHD remain largely unknown, with genetic factors, environmental toxins, and prenatal nutritional status under investigation. While some studies suggest correlations, concrete answers regarding the causes of neurodevelopmental conditions are elusive.
Dr. Zoe Martinez points to additional risk factors for ADHD, such as exposure to lead, low birth weight, and prematurity. One study indicates a correlation between prenatal acetaminophen exposure and higher ADHD rates, particularly with prolonged use.

Should Pregnant Individuals Avoid Tylenol?
Experts recommend a balanced approach, weighing the benefits of pain relief and fever reduction against potential risks. Dr. Al-Khan emphasizes that acetaminophen, when taken appropriately under medical guidance, is generally considered safe during pregnancy. The American College of Obstetrics and Gynecology echoes this stance.
While caution is warranted in medication use during pregnancy, withholding necessary relief may pose its own risks. Parents-to-be should adhere to recommended dosages and consult healthcare providers for guidance tailored to individual circumstances.
Dr. Hackney concludes that, until further research provides conclusive evidence, acetaminophen remains a viable option when beneficial, underscoring the importance of minimizing unnecessary medication use during pregnancy.
In discussions about potential links between prenatal medication and neurodevelopmental outcomes, it’s crucial to avoid stigmatizing neurodivergent individuals.
Autism and ADHD are developmental diversities, and children with these conditions lead fulfilling lives. Dr. Casares encourages parents to focus on understanding and embracing their child’s unique strengths, gifts, and opportunities for growth.
As the legal and scientific communities navigate these complexities, expectant parents are encouraged to make informed decisions, guided by medical advice and a nuanced understanding of the available evidence.
