Expectant mothers often take Tylenol, with the active ingredient acetaminophen, to deal with back pain, headaches or mild fevers during pregnancy. Is it safe to take Tylenol during pregnancy? This question has been asked by millions of pregnant women. Typically, they hear from their doctor that Tylenol during pregnancy is completely safe for both the mother and her developing baby.

However, a new Norwegian study has found symptoms aligned with autism spectrum disorder (ASD) in Tylenol-exposed children.  Children exposed to long-term use of paracetamol during pregnancy had substantially adverse developmental outcomes at three years of age.
