FDA warned healthcare professionals and breastfeeding women not to use an unapproved drug, domperidone, to increase milk production (lactation). The agency is concerned with the potential public health risks associated with domperidone. FDA took these actions because it has become aware that some women are purchasing this drug from compounding pharmacies and from foreign sources. Although domperidone is approved in several countries outside the U.S. to treat certain gastric disorders, it is not approved in any country, including the U.S., for enhancing breast milk production in lactating women and is also not approved in the U.S. for any indication.
