Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Over half of women in the US who are breastfeeding their infants take prescription drugs. You are being asked to participate in this study because you are breastfeeding your infant and are currently taking, as part of your medical care, at least one of the drugs we are studying. We are interested in studying drugs commonly prescribed to women who are breastfeeding so we can learn more about the amount of drug that is transferred to breastmilk and estimate how much of drug that is consumed by breastfed infants.
