This is an antibiotic ointment that is applied to the eyes of newborns to prevent ophthalmia neonatorum, a serious eye infection caused by gonorrhea.
Ophthalmia neonatorum can cause blindness if left untreated and can occur even if the mother does not have symptoms of gonorrhea.
Erythromycin is the only drug approved by the FDA for this purpose and is mandated in most states.
