Animal reproduction studies have not been conducted. Adverse events in the fetus or newborn have not been reported following maternal use of vaginal nystatin during pregnancy. Absorption following oral use is poor.
Monitor for oral irritation.
Binds to sterols in fungal cell membrane, changing the cell wall permeability allowing for leakage of cellular contents
Onset of action: Symptomatic relief from candidiasis: 24 to 72 hours.
