A major review has found no link between taking Tylenol during pregnancy and an increased risk of autism or ADHD in children. The review, which is described as one of the most comprehensive to date, examined the use of acetaminophen, also known as paracetamol, during pregnancy. However, some outlets also mention a study on antidepressant use during pregnancy, which found no clear link to autism or ADHD, creating some uncertainty about the specific focus of the research.
