There is no evidence acetaminophen use during pregnancy increases the risk of autism, ADHD, or intellectual disability in children. Dr. Grace Ferguson, MD is an OB/GYN at West Penn Hospital in Pittsburgh. She joined the Rick Dayton Show to discuss findings from analysis on 2.4 million children born in Sweden. Ferguson says the fact that many of these children are siblings is significant -- as siblings share genetics and upbringing. That allows researchers to weed out other variables that might lead to autism, ADHD and developmental delays.
