What did the 2nd U.S. Circuit Court of Appeals decide regarding the Tylenol-autism lawsuits, and why?

The 2nd U.S. Circuit Court of Appeals revived more than 500 private lawsuits against Kenvue, ruling that a district court judge improperly excluded expert testimony from three doctors—Andrea Baccarelli, Eric Hollander, and Brandon Pearson—who linked prenatal acetaminophen use to autism and ADHD in children; the appeals court held that their methodologies reflected accepted scientific practices and constituted 'acceptable interpretations of scientific evidence where scientists may, and in fact do, disagree.'

What is the current scientific and medical consensus on acetaminophen use during pregnancy, according to the news?

According to the news, there is 'no firm scientific evidence' linking Tylenol (acetaminophen) to autism or ADHD, and doctors and medical societies continue to consider acetaminophen 'the preferred means to treat pain and fever during pregnancy'; Kenvue and its former parent Johnson & Johnson have long maintained that Tylenol is safe, and no causal relationship has been established by the courts or medical authorities cited in the article.
