8 Use in Specific Populations

8.1  Pregnancy

(Pregnancy and Lactation Labeling Rule (PLLR) conversion; additions and/or revisions underlined)

Risk Summary

Limited available data with Technetium Tc 99m Sulfur Colloid Injection use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes; technetium Tc 99m crosses the placenta. Animal reproduction studies have not been conducted with Technetium Tc 99m Sulfur Colloid Injection. All radiopharmaceuticals, including Technetium Tc 99m Sulfur Colloid Injection, have a potential to cause fetal harm depending on the stage of fetal development and the magnitude of the radiopharmaceutical dose. If considering Technetium Tc 99m Sulfur Colloid Injection administration to a pregnant woman, inform the patient about the potential for adverse pregnancy outcomes based on the radiation dose from the drug and the gestational timing of exposure.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively.

Data

Human Data

Among 14 infants born to pregnant patients exposed to Technetium Tc 99m Sulfur Colloid Injection for lymph node localization, no birth defects were reported following drug exposure.

 8.2  Lactation

(Pregnancy and Lactation Labeling Rule (PLLR) conversion; additions and/or revisions underlined)

Risk Summary

Technetium Tc 99m is excreted in human milk during lactation. Exposure of Technetium Tc 99m Sulfur Colloid Injection to a breastfed infant can be minimized by temporary discontinuation of breastfeeding. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Technetium Tc 99m Sulfur Colloid Injection and any potential adverse effects on the breastfed child from Technetium Tc 99m Sulfur Colloid Injection or from the underlying maternal condition

Clinical Considerations

To decrease radiation exposure to the breastfed infant, advise a lactating woman to  pump  and discard breast milk for 24 hours after administration of Technetium Tc 99m Sulfur Colloid Injection. Following higher dose procedures [greater than 370 MBq (10 mCi)], patients should minimize close contact with infants for 6 hours after receiving a Technetium Tc 99m Sulfur Colloid Injection.
