In breastfeeding women with painful nipples, applying various treatments (including glycerine gel, breast shells with lanolin, expressed breast milk, lanolin or all-purpose nipple ointment) may make little or no important difference to nipple pain (low-certainty evidence). For most women, regardless of treatment used, pain may reduce to mild levels by about 7 to 10 days after giving birth (low certainty-evidence). There is not enough information available about the possible harms of interventions for painful nipples. Cochrane Review (published December 2014); four studies with 656 breastfeeding women with sore nipples. Studies compared applied lanolin (alone or with breast shells), glycerine pads, breast milk, all-purpose nipple ointment with each other, with routine care (education only) or with no treatment.
