Usage during Pregnancy and in Nursing Women: Since safety of Mometasone furoate product in pregnant women has not been established, topical corticosteroids should be used during pregnancy only if the potential benefit justifies potential risk to the fetus. Drugs of this class should not be used on pregnant patient in large amounts or for prolonged periods of time.
It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. Systemically administered corticosteroids are secreted into breast milk in quantities not likely to have a deleterious effect on the infant. Nevertheless, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
