BRL 2039 (flucloxacillin) is not approved for marketing in the United States by the U.S. Food and Drug Administration. It is acceptable to use during breastfeeding and is frequently used abroad to treat mastitis in nursing mothers.[1][2][3] Limited information indicates that BRL 2039 levels in milk are low and are not expected to cause adverse effects in breastfed infants.
