◉ 母乳喂养期间使用总结：局部使用的克洛卡松尚未在哺乳期进行过研究。由于只有大量使用最强效的皮质类固醇才可能在母亲体内产生系统性影响，因此短期使用局部皮质类固醇不太可能通过进入母乳而对哺乳婴儿构成风险。然而，最谨慎的做法是使用最弱效的药物，并尽可能在最小的皮肤区域上使用。特别是要确保婴儿的皮肤不直接接触涂抹了药物的区域。应仅在水溶性的乳膏或凝胶产品上涂抹在乳房上，因为软膏可能会使婴儿通过舔食接触到高水平的矿物石蜡。如果局部皮质类固醇被涂抹在乳房或乳头区域，应在哺乳前彻底擦除。
◉ 对哺乳婴儿的影响：将一种具有相对较高盐皮质激素活性的皮质类固醇（异氟泼尼松醋酸酯）局部应用于母亲的乳头，导致她两个月大的哺乳婴儿出现QT间期延长、库欣综合征外貌、严重高血压、生长减缓和电解质异常。这位母亲从婴儿出生起就因为乳头疼痛而使用该乳膏。

◉ Summary of Use during Lactation:Topical clocortolone has not been studied during breastfeeding. Since only extensive application of the most potent corticosteroids may cause systemic effects in the mother, it is unlikely that short-term application of topical corticosteroids would pose a risk to the breastfed infant by passage into breastmilk. However, it would be prudent to use the least potent drug on the smallest area of skin possible. It is particularly important to 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. Any topical corticosteroid should be wiped off thoroughly prior to nursing if it is being applied to the breast or nipple area.
◉ Effects in Breastfed Infants:Topical application of a corticosteroid with relatively high mineralocorticoid activity (isofluprednone acetate) to the mother's nipples resulted in prolonged QT interval, cushingoid appearance, severe hypertension, decreased growth and electrolyte abnormalities in her 2-month-old breastfed infant. The mother had used the cream since birth for painful nipples.
◉ Effects on Lactation and Breastmilk:Relevant published information was not found as of the revision date.
