Abstract

Although many female patients of childbearing age who are receiving cyclosporine have successful pregnancies, these women may be advised not to breast-feed. During recent years, cases of uneventful pregnancies and subsequent successful breast-feeding have been reported in the literature. The infant's blood cyclosporine concentration was usually very low. Based on these findings and the lack of detectable adverse effects, some investigators have suggested that women on cyclosporine may breast-feed, challenging the conventional view that cyclosporine is contraindicated during breast-feeding. Here, we report our experience with cyclosporine use during breast-feeding in five mother-infant pairs. We show a wide range of infant exposures to the drug in milk, noting that one of the infants had therapeutic blood concentrations of cyclosporine despite relatively low concentrations of the drug in milk.
