It is generally considered safe to take Tylenol (acetaminophen) during pregnancy for pain and fever relief, as it is the preferred over-the-counter medication compared to alternatives like ibuprofen or naproxen, which are not recommended in pregnancy. Recent large studies, including one from 2024, have shown no causal link between acetaminophen use in pregnancy and increased risks of neurodevelopmental disorders such as autism or ADHD in children. However, it is important to use the medication at the lowest effective dose and for the shortest possible duration, not exceeding the recommended maximum dosage (typically 3,000 mg per day). Pregnant individuals should also consult their healthcare provider before using Tylenol, especially for chronic or frequent use, to balance benefits with any potential risks. Untreated pain or fever during pregnancy can carry its own risks, so acetaminophen remains the safest known medication for such symptoms during pregnancy.
