Drug Levels and Effects

Summary of Use during Lactation

Topical benzoyl peroxide has not been studied during breastfeeding. Because only about 5% is absorbed following topical application, it is considered a low risk to the nursing infant.[1,2] Ensure that the infant's skin does not come into direct contact with the areas of skin that have been treated. 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.[3]
