While it is advisable to limit the amount of medications taken while breastfeeding, it is not always possible to do so. In 1998, the Center for Disease and Control (CDC) found that Tylenol, or acetaminophen, is the most common medicine taken by women during their child-bearing years. Lactation expert Kelly Bonyata, creator of the breastfeeding website www.kellymom.com, shares that on a one-to-five scale of risk for medications to take while lactating, Tylenol rates one–the lowest risk. It has been approved by the American Academy of Pediatrics for breastfeeding mothers.
