This is quite a concerning study. A new study by Mount Sinai and Harvard’s School of Public Health has revealed that using paracetamol during pregnancy leads to bigger risks of autism and ADHD in children. After researching over 100,000 people, researchers concluded that paracetamol, which is sold under the brand name of Tylenol in the United States, leads to the risk of autism and ADHD in children. A new large-scale review of 50 published studies find a clear link between tylenol use during pregnancy and ADHD and autism in children. Experiments suggest tylenol exposure during gestation causes oxidative stress in the baby’s brain tissue, leading to developmental issues. pic.twitter.com/afqSAoHVwp — RAW EGG NATIONALIST (@Babygravy9) August 15, 2025 The Daily Mail reported more details on the links between Tylenol and autism: Pregnant women should only take paracetamol on the advice of a doctor, Harvard scientists have warned—amid fears the common painkiller could raise the risk of autism and ADHD in their children. Paracetamol—known as acetaminophen and often sold under the brand name Tylenol in the US—is widely used by expectant mothers to treat pain, headaches and fever. But dozens of studies have already linked it to higher rates of autism and attention deficit hyperactivity disorder (ADHD). Now US researchers from Mount Sinai and Harvard’s School of Public Health say their analysis of more than 100,000 people is the most comprehensive yet—and provides the ‘strongest evidence so far’ of a link. They urged mothers-to-be to use paracetamol sparingly, recommending only ‘the lowest effective dose for the shortest possible time.’ However, the team stressed the findings do not prove the drug directly causes neurodevelopmental disorders—only that the association is consistent and worrying enough to demand further investigation. Dr Diddier Prada, assistant professor of population health science at Mount Sinai Hospital in New York and co-author of the study, said: ‘Our findings show that higher-quality studies are more likely to show a link between prenatal acetaminophen exposure and increased risks of autism and ADHD.’ there are massive ongoing lawsuits against tylenol for causing ADHD and Autism acetaminophen is one of the worst things for your health stop taking tylenol at all costs, and this includes tylenol containing products like dayquil and nyquil pic.twitter.com/Wahhxrkk75 — Carnivore Aurelius © (@AlpacaAurelius) May 26, 2023 Here’s the official Harvard research press release: When children are exposed to acetaminophen—also known by the brand name Tylenol or as paracetamol—during pregnancy, they may be more likely to develop neurodevelopmental disorders (NDDs) including autism and ADHD, according to a new study. The researchers analyzed results from 46 previous studies—representing data from over 100,000 participants—that investigated the potential link between prenatal acetaminophen use and subsequent NDDs in children. The researchers used the Navigation Guide Systematic Review methodology—a gold-standard framework for synthesizing and evaluating environmental health data—which enabled them to conduct a rigorous, comprehensive analysis that supported evidence of an association between acetaminophen exposure during pregnancy and increased incidence of NDDs. The researchers noted that while steps should be taken to limit acetaminophen use, the drug is important for treating maternal fever and pain, which can also harm children. “We recommend judicious acetaminophen use—lowest effective dose, shortest duration—under medical guidance, tailored to individual risk-benefit assessments, rather than a broad limitation,” they wrote.
