Tylenol (acetaminophen) is generally considered safe to use during pregnancy for pain and fever relief. Recent research, including a 2024 study, finds no increased risk of neurodevelopmental disorders such as autism or ADHD with acetaminophen use during pregnancy. Medical experts and organizations like the American College of Obstetricians and Gynecologists recommend acetaminophen as the safest over-the-counter option during pregnancy, especially compared to alternatives like ibuprofen or naproxen, which are not recommended. However, it is advised to use the lowest effective dose for the shortest duration and always consult a healthcare provider before use during pregnancy. Untreated fever or pain can pose greater risks to both the mother and baby than acetaminophen when used appropriately. In short, Tylenol is recommended during pregnancy when medically necessary and under medical guidance, not contraindicated as once feared.
