What pregnancy category is Tylenol classified under?

Tylenol, known generically as acetaminophen, is classified as a pregnancy category B medication. This classification indicates that studies in pregnant animals have not demonstrated a risk to the fetus, and there are no adequate and well-controlled studies in pregnant women. Essentially, while animal studies have shown safety, there is limited data in humans, but it is generally considered safe when used as directed during pregnancy.

This category allows healthcare providers to feel confident when recommending Tylenol for pain relief or fever reduction in pregnant individuals, as the risk of harm to the developing fetus is considered low. The other categories, such as A, C, and D, indicate varying levels of risk and safety concerns, reinforcing why B is the appropriate classification for Tylenol.
