It has an anti-bacterial, anti-fungal & anti-inflammatory ingredients. You have to get it made up at a compounding pharmacy or a hospital pharmacy. Lanisoh and breastmilk are not good for thrush, a yeast infection in your nipples. Sore nipples are very susceptible to thrush and the APNO will help prevent infection.
