Tylenol use during pregnancy not linked to autism, new study says
Acetaminophen use during pregnancy is not likely to raise the risk of having a child with autism, ADHD, or intellectual disability, according to a new study published Friday.
Researchers across Europe reexamined evidence from multiple studies investigating the link between these conditions and the use of paracetamol called acetaminophen in the United States and found that these purported associations fell apart after controlling for confounding factors.
Acetaminophen, the active ingredient in Tylenol, has long been a frontline medication for relieving pain or fever in people who are pregnant. The scientific literature shows that this practice shouldnt change, said co-author Asma Khalil, obstetrics and maternal fetal medicine professor at St. Georges Hospital, University of London.

Independent health experts praised the studys methods and conclusions, which diverge sharply from the recommendations offered by President Trump and top health officials in September, when they said that acetaminophen should be used only if absolutely needed during pregnancy and launched a nationwide public information campaign to inform doctors and families of the purported risk. Their announcement came as part of their bid to find the cause of autism, which decades of research has already linked to primarily genetic factors.
