"Prescribing decisions during pregnancy and lactation are individualized and involve complex maternal, fetal and infant risk-benefit considerations. The letter category system was overly simplistic and was misinterpreted as a grading system, which gave an over-simplified view of the product risk," said Sandra Kweder, M.D, deputy director of the Office of New Drugs in the FDA's Center for Drug Evaluation and Research. "The new labeling rule provides for explanations, based on available information, about the potential benefits and risks for the mother, the fetus and the breastfeeding child."
The Pregnancy subsection will provide information relevant to the use of the drug in pregnant women, such as dosing and potential risks to the developing fetus, and will require information about whether there is a registry that collects and maintains data on how pregnant women are affected when they use the drug or biological product. Information in drug labeling about the existence of any pregnancy registries has been previously recommended but not required until now.
The Lactation subsection will provide information about using the drug while breastfeeding, such as the amount of drug in breast milk and potential effects on the breastfed child.
The Females and Males of Reproductive Potential subsection will include information about pregnancy testing, contraception and about infertility as it relates to the drug. This information has been included in labeling, but there was no consistent placement for it until now.
The "Pregnancy" and "Lactation" subsections will also include three subheadings: "risk summary," "clinical considerations" and "data." These subheadings will provide more detailed information regarding, for example, human and animal data on the use of the drug, and specific adverse reactions of concern for pregnant or breastfeeding women.
There are over six million pregnancies in the United States every year, and pregnant women take an average of three to five prescription drugs during pregnancy. Women with pre-existing medical conditions, such as asthma or high blood pressure, may need to continue to use prescription drugs to treat those conditions during pregnancy and breastfeeding. Women may also need to take medications for new or acute conditions that may occur during pregnancy or breastfeeding. The new labeling format and requirements reorganizes information and is structured to help inform health care professionals' prescribing decisions and the counseling of patients using prescription drugs.
The rule finalizes many of the provisions in the proposed rule that the FDA issued in May 2008, and will be in effect as of June 30, 2015. Once the final rule is in effect, newly approved drug and biological product applications will be required to use the new format immediately, while the new labeling content and format requirements for previously approved products subject to the Physician Labeling Rule will be phased in gradually.
