If you are taking a medication approved by the FDA after June 2015, you might notice that the labeling insert around pregnancy and lactation has changed. In response to problems with the old labeling system, the FDA has started a new labeling system around pregnancy and lactation. All medications approved after June 2015 have the new labeling, medications approved between 2001-2015 will have until 2020 to make revisions, and medications approved prior to 2001 are not required to have revisions.
