Another large study has found no link between autism and Tylenol use during pregnancy, refuting claims by President Trump and anti-vaccine Health Secretary Robert F. Kennedy Jr.
In September, Trump and Kennedy held a press conference in which they stated without clear evidence that the common fever and pain reducer acetaminophen—sold as Tylenol in the US and also known as paracetamol—causes autism in children if taken during pregnancy. Trump repeatedly warned pregnant people not to take Tylenol and instead "tough it out" with fever and/or pain.
Medical organizations decried Trump's message, emphasizing that acetaminophen is a safe pain and fever reliever during pregnancy and that untreated fever during pregnancy is known to increase the risk of autism in babies as well as other conditions, including miscarriage, birth defects, and premature birth. Still, the president's warning was effective. Texas sued the maker of Tylenol over the alleged connection. And a study in The Lancet in March found that use of acetaminophen in pregnant patients in emergency departments fell by 10 percent after Trump's press conference.
