Pregnancy & Breastfeeding
8.1 Pregnancy Pregnancy Category C It is not known whether Radiogardase can cause fetal harm when administered to a pregnant woman or if it can affect reproduction capacity. Animal reproduction studies have not been conducted with prussian blue insoluble. However, since Radiogardase is not absorbed from the gastrointestinal tract, effects on the fetus are not expected. Radioactive cesium ( 137 Cs) crosses the human placenta. One patient, contaminated with 0.005 mCi 137 Cs during her 4 th month of pregnancy, was not treated with Radiogardase. At birth, the concentration of 137 Cs was the same in the mother and the infant. Thallium crosses the human placenta. Reported fetal effects include failure to thrive and death. The toxicity from untreated radioactive cesium or thallium exposure is greater than the potential reproductive toxicity of Radiogardase.
