Summary of Use during Lactation

Because it is poorly absorbed after topical application and oral ingestion, bacitracin is considered a low risk to the nursing infant.[1] Only water-miscible cream or gel products should be applied to the breast because ointments may expose the infant to high levels of mineral paraffins via licking.[2] Therefore, an alternate cream product is preferred for application to the breast.
