Federal court revives 550 lawsuits linking Tylenol to autism: 5 things to know

A federal appeals court has revived around 550 lawsuits that claim prenatal Tylenol use may be linked to autism and ADHD, reversing a previous decision that dismissed these cases as based on unreliable science. The court's ruling was narrow, focusing on the reliability of expert testimony rather than establishing a causal link. This decision could have significant implications for future litigation involving pharmaceutical products and the standards required for expert testimony in such cases. It highlights the ongoing debate over scientific evidence and its role in legal proceedings.
