Ioflupane I 123 Pregnancy Warnings

Use is not recommended unless clearly needed.

US FDA pregnancy category: C

Comments: Assess for the presence of pregnancy prior to administering this drug to women of childbearing potential.

Animal reproductive and developmental toxicity studies have not been conducted. Like all radiopharmaceuticals, this drug has a potential to cause fetal harm. The likelihood of fetal harm depends on the stage of fetal development, and the magnitude of the radionuclide dose. Administration of ioflupane I-123 at a dose of 185 MBq (5 mCi) results in an absorbed radiation dose to the uterus of 0.3 rad (3.0 mGy). Radiation doses greater than 15 rad (150 mGy) have been associated with congenital anomalies. Radioactive iodine products cross the placenta and can permanently impair fetal thyroid function. There are no controlled data in human pregnancy.

US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
