Azelaic Acid Levels and Effects while Breastfeeding
Summary of Use during Lactation
Topical azelaic acid has not been studied during breastfeeding. Because only 4% of a dose is absorbed after topical application and it is a chemical that appears in foods, bloodstream and breastmilk normally, azelaic acid is considered a low risk to the nursing infant.[1-3] If azelaic acid is required by the mother, it is not a reason to discontinue breastfeeding. Do not apply azelaic acid to the breast or nipple and 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.[4]
