Drug Levels and Effects

Summary of Use during Lactation

Tretinoin has not been studied during breastfeeding. Breastfeeding should probably be avoided after oral use. Because it is poorly absorbed after topical application, it is considered a low risk to the nursing infant.[1] Do not apply tretinoin directly to the nipple and areola and ensure that the infant's skin does not come into direct contact with the areas of skin that have been treated.
