Tylenol (acetaminophen) has been a go-to pain and fever relief option during pregnancy for decades. However, epidemiological studies have found associations between prenatal exposure and neurodevelopmental disorders including autism spectrum disorder and ADHD.

The litigation, consolidated into MDL 3043, alleges that manufacturers failed to warn about the risks of prenatal acetaminophen use. Defendants maintain that the products are safe when used as directed and that causation is not established.

If you took acetaminophen during pregnancy and your child was diagnosed with autism or ADHD, preserve medical records and pharmacy receipts, and speak with counsel about deadlines.
