Pregnant and worried about taking paracetamol? A major new study says you can breathe easy.
A groundbreaking analysis published in The Lancet Obstetrics, Gynaecology & Women’s Health has put to rest the controversial claims linking paracetamol use during pregnancy to autism spectrum disorder (ASD), attention-deficit hyperactivity disorder (ADHD), or intellectual disability in children. But here's where it gets controversial: this study directly counters statements made by former US President Donald Trump in 2025, which sparked widespread public concern. At the time, Trump suggested pregnant women should “strongly” limit paracetamol use, a claim that was swiftly debunked by Australian experts and health authorities.
So, what’s the real story?
This latest research, hailed as a gold-standard analysis, synthesized data from 43 studies and included pooled analyses from 17 of them. The researchers employed rigorous methods, such as sibling comparisons, to control for shared genetic and environmental factors—a design that helps separate the effects of the medication from other influences. And this is the part most people miss: the study found no evidence of a causal link between paracetamol exposure in utero and later diagnoses of ASD, ADHD, or intellectual disability. Instead, previously observed associations were likely due to underlying maternal factors like fever, pain, or inflammation, rather than the medication itself.
Why does this matter?
Paracetamol is often the safest—and sometimes the only—option for managing pain or fever during pregnancy. Untreated maternal fever, for instance, can pose serious risks to both mother and fetus. Dr. Anya Arthurs, a leading researcher from the University of Adelaide, emphasizes that earlier alarm was likely driven by confusion between cause and coincidence. “People who need paracetamol during pregnancy may already be dealing with illness, infection, or inflammation,” she explains. “Those factors, not the medication, are far more likely to influence child development.”
The bigger picture: Evidence over fear
Australian experts caution against the politicization of scientific uncertainty, warning that selective interpretation of data can undermine evidence-based care. Associate Professor Alex Polyakov highlights that paracetamol has been a cornerstone of obstetric practice for decades due to its favorable balance of maternal benefit and fetal safety. He calls precautionary advice to avoid paracetamol “a misapplication of the precautionary principle, divorced from proportionality and clinical reality.”
But what do you think?
Is it fair to question the safety of medications based on limited or misinterpreted data? Should public figures like former President Trump weigh in on such complex medical issues? Let us know in the comments below. This study not only reassures pregnant women and clinicians but also underscores the importance of relying on robust evidence when making health decisions. As Professor David Trembath aptly puts it, “This research helps bring the conversation back to evidence, balance, and common sense—and that reassurance is incredibly important for families.”
