It is not known whether Zadaxin can cause fetal harm when administered to pregnant women or can affect reproduction capacity. Zadaxin should be given to pregnant women only if the benefits clearly outweigh the risks.
Use in lactation: It is not known whether Zadaxin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Zadaxin is administered to a nursing woman.
