Because of a small dose used and low absorption through skin (less than 1%), excretion into breast milk in significant amount is unlikely. Despite of it is well absorbed by the gut, it is rapidly and completely metabolized into Monic acid which is a non-active metabolite. However, whenever used on the nipple, it is recommended remove excess of cream by using a gauze. Effectiveness is not higher than purified Lanolin for treatment of sore or cracked nipples. Results in the treatment of nipple infection due to Staph. aureus are less encouraging than with the use of oral antibiotics. Caution should be observed with the application of creams, gels and other products that are indicated for local use if they contain paraffin (Mineral oil) to avoid absorption by the infant.
