Pregnancy: MPA is contraindicated in women who are pregnant.
Some reports suggest under certain circumstances, an association between intrauterine exposure to progestational drugs in the first trimester of pregnancy and genital abnormalities in fetuses.
If the patient becomes pregnant while using this drug, the patient should be apprised of the potential hazard to the fetus.
Lactation: MPA and its metabolites are excreted in breast milk. There is no evidence to suggest that this presents any hazard to the nursing child.
