Hypersensitivity Reactions: Hypersensitivity reactions, including serious signs and symptoms of anaphylaxis, following administration of Tc 99m labeled leukocytes prepared using Tc 99m exametazime have been reported. Always have cardiopulmonary resuscitation equipment and personnel available and monitor all patients for hypersensitivity reactions. ( 5.1 ) 5.1 Hypersensitivity Reactions Hypersensitivity reactions, including serious signs and symptoms of anaphylaxis, following administration of Tc 99m labeled leukocytes prepared using Tc 99m exametazime have been reported. Always have cardiopulmonary resuscitation equipment and personnel available and monitor all patients for hypersensitivity reactions. 5.2 Risk for Image Interpretation Error The interpretation of images can be affected by the presence of other pathophysiological processes within and outside of the abdominal cavity such as: tumor, infarction, trauma, and other inflammatory conditions. 5.3 Radiation Exposure Risk Technetium Tc 99m contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Ensure safe handling and preparation reconstitution procedures to protect patients and health care workers from unintentional radiation exposure. Encourage patients to drink fluids and void as frequently as possible after administration [see Dosage and Administration ( 2.1, 2.2 )] .

8.1 Pregnancy Risk Summary Limited available data with technetium Tc 99m exametazime use in pregnant women are insufficient to inform a drug associated risk for major birth defects and miscarriage. Technetium Tc 99m exametazime is transferred across the placenta [see Data] . Animal reproduction studies with technetium Tc 99m exametazime have not been conducted. However, all radiopharmaceuticals have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose. If considering technetium Tc 99m exametazime administration to a pregnant woman, inform the patient about the potential for adverse pregnancy outcomes based on the radiation …
