Nystatin topical Breastfeeding Warnings

There are no data on the excretion of nystatin into human milk. However, nystatin is not thought to be absorbed after application to skin or mucous membranes; therefore, significant milk levels are not expected. The manufacturer recommends that caution be used when administering nystatin topical to nursing women.
