Is Siloxane-coated superparamagnetic iron oxide Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Siloxane-coated superparamagnetic iron oxide? Is Siloxane-coated superparamagnetic iron oxide safe for nursing mother and child? Does Siloxane-coated superparamagnetic iron oxide extracts into breast milk? Does Siloxane-coated superparamagnetic iron oxide has any long term or short term side effects on infants? Can Siloxane-coated superparamagnetic iron oxide influence milk supply or can Siloxane-coated superparamagnetic iron oxide decrease milk supply in lactating mothers?

Siloxane-coated superparamagnetic iron oxide is not approved for marketing in the United States by the U.S. Food and Drug Administration. No information is available on the clinical use of Siloxane-coated superparamagnetic iron oxide during breastfeeding. If Siloxane-coated superparamagnetic iron oxide is required by the mother, it is not a reason to discontinue breastfeeding.[1] However, because there is no published experience with Siloxane-coated superparamagnetic iron oxide during breastfeeding, other agents may be preferred, especially while nursing a newborn or preterm infant.
