Acetaminophen, the drug marketed under the name Tylenol, is the first line medication for treating fever in pregnant women, and the alternatives, as the obstetrician and professor at the University of Liverpool knew, can be dangerous. Taking non-steroidal antiinflammatory ibuprofen, marketed under the name Advil, interferes with a developing fetus’s cardiovascular system. Letting a fever rage unchecked, on the other hand, means exposing the fetus to harmful substances produced as the mother fights off her infection. But healthcare providers, she knew, were likely to be inundated by questions: “A lot of the professional bodies in response to the US announcement said, ‘If you are worried, go talk to your healthcare professional’,” Thangaratinam says. **Read more:** [_Texas Is Suing Tylenol Makers Over Claims of Links to Autism. Here’s Everything to Know About the Lawsuit_](https://time.com/7328910/tylenol-autism-lawsuit-texas/) Recognizing that clinicians would need clear, evidence-based guidance to reassure worried patients, Thangaratinam and her colleagues undertook a comprehensive review of the existing research, which they have now [published](https://www.bmj.com/content/391/bmj-2025-088141) in the _British Medical Journal._ They found that many studies that show a link between acetaminophen and autism and ADHD do not control well for the fact that these diagnoses often travel in families. When, in a handful of better-designed studies, siblings of children with a diagnosis were included, the link weakened substantially. In particular, Thangaratinam highlights two [Scandinavian](https://www.bmj.com/lookup/google-scholar?link%5Ftype=googlescholar&gs%5Ftype=article&author[0]=VH+Ahlqvist&author[1]=H+Sj%C3%B6qvist&author[2]=C+Dalman&title=Acetaminophen+Use+During+Pregnancy+and+Children%E2%80%99s+Risk+of+Autism,+ADHD,+and+Intellectual+Disability&publication%5Fyear=2024&journal=JAMA&volume=331&pages=1205-14) [studies](https://scholar.google.com/scholar%5Flookup?author=K+Gustavson&author=E+Ystrom&author=H+Ask&title=Acetaminophen+use+during+pregnancy+and+offspring+attention+deficit+hyperactivity+disorder+-+a+longitudinal+sibling+control+study&publication%5Fyear=2021&journal=JCPP+Adv&volume=1) and a [Japanese study](https://onlinelibrary.wiley.com/doi/10.1111/ppe.70071), in which large numbers of families were followed. In these studies, researchers compared sibling pairs in which one child had been exposed to acetaminophen in utero and the other had not. **Read more:** [_Does Tylenol Cause Autism? RFK Jr. Is Forcing America to Ask the Wrong Question._](https://time.com/7322067/tylenol-autism-rfk-jr-science/) “What we found was consistently in \[these studies\], the association that was initially present went away when a sibling control analysis was done,” she says. There was no difference in the diagnosis rates between these siblings, despite their different experiences during gestation. Compiling the survey reinforced Thangaratinam’s sense that there is not enough quality information available, in many cases, for pregnant women to make informed decisions. Pregnant women are traditionally excluded from drug trials, so there is little known about the effects of many common medications on pregnancies. She called it “one of the biggest messages that needs to be highlighted in women's health”: More studies that focus on medication for pregnant women will result in better outcomes. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/7332779/tylenol-autism-adhd-trump/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/7332779/tylenol-autism-adhd-trump/"},"headline":"No Evidence of Link Between Tylenol and Autism or ADHD, Study Confirms","datePublished":"2025-11-10T21:29:24.000Z","dateModified":"2026-03-11T00:32:13.048Z","description":"A review in the BMJ concludes current research does not establish a link between acetaminophen use in pregnancy and autism or ADHD in children.","url":"https://time.com/7332779/tylenol-autism-adhd-trump/","keywords":["Health Care"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltad9b106f2031c1f3/6998cb8883ec375ecfc7b1e2/GettyImages-2244403043.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Veronique Greenwood","jobTitle":"","url":"https://time.com/author/veronique-greenwood/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltad9b106f2031c1f3/6998cb8883ec375ecfc7b1e2/GettyImages-2244403043.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Kimberly-Clark To Buy Tylenol Maker Kenvue For $40 Billion","caption":"Kimberly-Clark To Buy Tylenol Maker Kenvue For $40 Billion","creditText":"Michael Nagle—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/health-care/","name":"Health Care"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/7332779/tylenol-autism-adhd-trump/","name":"No Evidence of Link Between Tylenol and Autism or ADHD, Study Confirms"}}]}] ```
