Excretion into breast milk is highly unlikely due to an almost nil systemic absorption through the skin, vaginal mucosa and even the intestine, with non-significant plasma levels (< 1 mcg/ mL) observed. In case of use on the nipple, let it be done after the feed and wipe it out any excess of cream before the next feed. Do not apply creams, gels and other products that would contain paraffin (mineral oil) to avoid absorption by the infant since it is a hydrocarbon-derived substance. Miconazole has not been found to be more effective than pure lanolin for treatment of sore or cracked nipples. List of Essential Medicines by WHO 2002: compatible with breastfeeding.
