Paracetamol in Pregnancy: Rigorous Review Finds No Link to Neurodevelopmental Disorders
Published: 2026/01/23 02:17:09
A complete new review has delivered reassuring news for expectant mothers: there is no evidence to suggest that taking paracetamol (acetaminophen) during pregnancy increases the risk of autism, ADHD, or intellectual disabilities in children.The findings,published in The Lancet Obstetrics & Gynaecology,represent the most rigorous analysis of the available evidence to date,examining data from over 775,000 children.
Debunking Misinformation and Addressing Parental Anxiety
The study directly addresses concerns raised last year following unsubstantiated claims made by former U.S. President Donald Trump, who asserted that paracetamol was linked to autism . These statements sparked widespread anxiety among pregnant women, given that paracetamol is a commonly recommended pain and fever reliever during pregnancy by healthcare professionals worldwide.
“This systematic review and meta-analysis found no evidence that maternal paracetamol use during pregnancy increases the risk of autism spectrum disorder, ADHD or intellectual disability among children,” states the research, led by Professor Asma khalil of City, University of London . The research team meticulously analyzed 43 previous studies, encompassing a substantial sample size – 262,852 children assessed for autism, 335,255 for ADHD, and 406,681 for intellectual disability.
What the Research Examined
The researchers weren’t simply looking for a correlation; they aimed to assess the quality of existing evidence. They scrutinized studies for potential biases and inconsistencies, ensuring a robust and reliable conclusion. The analysis focused on comparing outcomes among children born to the same mother – some exposed to paracetamol during gestation and others not – to minimize confounding factors.
The review considered a wide range of study designs and methodologies, strengthening the overall confidence in the findings. Importantly, the researchers acknowledged that previous associations observed in some studies were more likely attributable to familial and genetic predispositions to neurodevelopmental conditions, rather than a direct causal link to paracetamol use.
Why Paracetamol remains a Safe Option
Professor Khalil emphasized the importance of the findings for clinical practice: “The message is clear: paracetamol remains a safe option during pregnancy when taken as guided.” She explained that paracetamol is often the first-line medication recommended for managing pain and fever in pregnant women, and the study provides reassurance that its use dose not pose a meaningful risk to the developing child .
The researchers also highlighted a crucial point: avoiding paracetamol when medically necessary could expose both mother and baby to risks. Untreated maternal fever,such as,is known to have adverse effects on pregnancy outcomes.
Beyond the Drug Itself: Considering Underlying Conditions
the study also delves into the possibility that the reason a pregnant woman is taking paracetamol might be more relevant than the drug itself. “Paracetamol is typically used only intermittently, and its prolonged use raises questions about whether the underlying health condition prompting extended use might be more vital in shaping neurodevelopmental outcomes rather than the drug itself,” the researchers noted.
This suggests that factors like infection, inflammation, or chronic pain – the conditions that frequently enough necessitate paracetamol use – could potentially play a role in neurodevelopment, independent of the medication.
Expert Reaction and Public Health Implications
The findings have been welcomed by medical professionals and public health officials. Experts like Grainne McAlonan, a professor of translational neuroscience at King’s college London, expressed hope that the study would “bring the matter to a close” and alleviate unnecessary stress for expectant mothers.
Dr. Steven Kapp, a senior lecturer in psychology at the University of Portsmouth, underscored the broader societal implications, stating that “society needs to stop going down rabbit holes of seeking false prevention of developmental disabilities. Instead, we should focus on making the world a better place for disabled people.”
Wes Streeting, the UK’s health secretary, urged the public to disregard misinformation, stating, “Our country’s leading scientists, doctors, and the NHS are clear that paracetamol is safe to take when pregnant and in pain or suffering a fever” .
Key Takeaways:
- A comprehensive review of 43 studies found no link between paracetamol use during pregnancy and an increased risk of autism, ADHD, or intellectual disabilities.
- The findings refute previous,unsubstantiated claims linking paracetamol to neurodevelopmental disorders.
- Paracetamol remains a safe and recommended option for managing pain and fever during pregnancy when used as directed.
- Underlying health conditions prompting paracetamol use might potentially be more influential on neurodevelopmental outcomes than the drug itself.
This research provides strong evidence to support the continued use of paracetamol during pregnancy when medically indicated, offering reassurance to expectant mothers and reinforcing the importance of evidence-based medical guidance.
