Hi. I'm hardly an expert on the matter, since I'm a guy. But I did a little research and this is what I found on the National Institute of Health Website:
Infants exposed to AZA in early pregnancy may be at a moderately increased risk of congenital malformations, specifically ventricular/atrial septal defects. There is also an increased risk of growth restriction and preterm delivery. These associations may be confounded by the severity of maternal illness.
Other websites seem to say this drug is contraindicated for women who are pregnant or may become pregnant.
