A keratolytic and topical anti-infective agent used in the treatment of acne. Since the last update we have not found published data on its excretion in breast milk Only 5% is absorbed through the skin and is quickly eliminated via urine after being metabolized in the skin to benzoic acid (AEMPS 2013, Seubert 1984, Holzmann 1979), so it is not expected to pass into breast milk.Taken orally, it is destroyed at the gastrointestinal level, so its absorption into milk is zero. It is considered very low risk during breastfeeding (Kong 2013, Worret 2006, Leachman 2006, Zip 2002). Do not apply to the chest in order to prevent the infant from ingesting it; if necessary, apply after breastfeeding and clean well with water before the next feed. Applying topical creams, gels and other products which contain paraffin (mineral oil) to the nipple is to be avoided so that the infant does not absorb them. (Concin 2008, Noti 2003).
