RESUMO
Breastfeeding is an important aspect of mother-newborn relationship and is of great benefit for the baby. Unfortunately, many drugs taken by the mother may pass into her milk and exert an effect on the newborn. Very limited data is available and a cautionary approach is warranted especially when the woman receives anticancer treatment including chemotherapy , hormonal treatment and the recently introduced target agents as well as monoclonal antibodies. In all these conditions breastfeeding should be put on hold.More and more often physicians are faced with women that are pregnant years after the diagnosis of cancer: this has long been considered dangerous for the mother, but data show that prognosis is definitely not worse. If the woman is no longer being actively treated, breastfeeding is advisable every time it is possible, even if patients that received breast radiation may be unable to produce a sufficient amount of milk on that side.

INTRODUCTION: The lack of consistent official information on the use of medications during lactation is probably one of the main reasons leading to an excess of prudence, based on presumption of risk rather than on evidence. The objective of this study was to compare the level of agreement between different official sources available to doctors and women on the use of medications during lactation. MATERIALS AND METHODS: Sources of information included governmental regulatory agencies (RAs) and scientific sources (SS). The package leaflets (PLs) and summaries of product characteristics (SPCs) were retrieved from online databases of the European Union and U.S. RAs. Among the SS, the latest edition of the book Medications and Mothers' Milk by Hale and Rowe and the LactMed database were selected. Information about the use of 11 antihypertensive medications during breastfeeding was analyzed. RESULTS: The PLs and SPCs report a higher risk profile than the one expressed by SS, and they often suggest the interruption of lactation even for compatible medications. CONCLUSIONS: Health professionals should be supported by official, accurate, comprehensive, and consistent information about maternally ingested medication and breastfeeding management to facilitate proper decision-making.
