Drug Levels and Effects

Summary of Use during Lactation

Topical pimecrolimus has not been studied during breastfeeding; however, it is used topically in children as young as 3 months of age. Because it is poorly absorbed after topical application and plasma concentrations after topical use in adults are less than 2 mcg/L, it is a low risk to the nursing infant. . Ensure that the infant's skin does not come into direct contact with the areas of skin that have been treated. Older recommendations state that if the breast is to be treated, an alternate drug is preferred; do not apply to the nipple area while nursing.[1][2] A newer European guideline allows pimecrolimus to be applied just after nursing, with the nipples cleaned gently and carefully before nursing.[3] 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]
