per the PDR

Although it is classified as a pregnancy category B drug for use during pregnancy, nitrofurantoin can induce hemolytic anemia in G6PD-deficient patients and in patients whose RBCs lack sufficient quantities of reduced glutathione. Since neonates exhibit this latter condition, generally it is wise to avoid the use of this drug during late pregnancy; however, hemolytic anemia in the newborn as a result of in utero exposure to nitrofurantoin has not been reported. Nitrofurantion is contraindicated in pregnancy at term (38-42 weeks gestation), during labor or obstetric delivery, or in neonates < 1 month old. Nitrofurantoin is distributed into breast milk and should be used with caution in breast-feeding women, especially in infants with G6PD deficiency.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
