Do not use Sodium Pertechnetate Tc 99m containing oxidants to reconstitute this kit. The contents of the kit are not radioactive. However, after the Sodium Pertechnetate Tc 99m is added, maintain adequate shielding of the final preparation. Wear waterproof gloves during the preparation procedure. Do not use Sodium Pertechnetate Tc 99m containing more than 10 micrograms per mL of aluminum ion because a flocculent precipitate may occur and such a precipitate may localize in the lung. The contents of the kit are sterile and non-pyrogenic. This preparation contains no bacteriostatic preservative (preservative-free). Follow the directions carefully and adhere strictly to aseptic procedures during preparation. Prepare Technetium Tc 99m Sulfur Colloid Injection by the following aseptic procedure: Remove the dark brown plastic cap from the Sulfur Colloid Multi-Dose Reaction Vial and swab the top of the vial closure with alcohol to sterilize the surface. Complete the radiation label and affix to the vial. Place the vial in an appropriate lead-capped radiation shield labeled and identified. With a sterile shielded syringe, aseptically obtain 1 to 3 mL of a suitable, oxidant-free sterile and non-pyrogenic Sodium Pertechnetate Tc 99m, each milliliter containing a maximum activity of 18,500 MBq (500 mCi). Aseptically add the Sodium Pertechnetate Tc 99m to the vial. Place a lead cover on the vial shield and dissolve the reagent by gentle swirling. Just before use, remove the red cap from the Solution A vial and swab the top of the vial closure with alcohol to sterilize the surface. Using a sterile needle and syringe, aseptically withdraw 1.5 mL Solution A from the vial. Aseptically inject 1.5 mL Solution A into the Multi-Dose Reaction Vial and swirl again. Transfer the Multi-Dose Reaction Vial from vial shield and place in a vigorously boiling water bath (water bath should be shielded with 1/8” to 1/4” lead) deep enough to cover the entire liquid contents of the vial. Keep the vial in the water bath for five minutes. Remove the Multi-Dose Reaction Vial from the water bath and place in the lead shield and allow to cool for three minutes. Swab the vial closure again with an antiseptic. Just before use, remove the blue cap from the Solution B vial and swab the top of the vial closure with alcohol to sterilize the surface. Using a sterile needle and syringe, aseptically withdraw 1.5 mL Solution B from the vial. Aseptically inject 1.5 mL Solution B into the Multi-Dose Reaction Vial and swirl again. Record time and date of preparation. Allow the preparation to cool to body temperature before use. Maintain adequate shielding of the radioactive colloid preparation at all times. Where appropriate, dilute the preparation with sterile Sodium Chloride Injection to bring the dosage to within the recommended range. Mix the Multi-Dose Reaction Vial and aseptically withdraw material with a sterile shielded syringe for use within 6 hours of preparation. For optimum results this time should be minimized. The vial contains no bacteriostatic preservative (preservative-free). Store the reconstituted vial at 20°C to 25°C (68°F to 77°F). Discard vial 6 hours after reconstitution. Carefully agitate the shielded syringe immediately prior to administration of sulfur colloid to avoid particles aggregation and non-uniform distribution of radioactivity. Measure the patient dose by a suitable radioactivity calibration system immediately before administration. Check radiochemical purity before patient administration. Inspect Technetium Tc 99m Sulfur Colloid Injection visually for particulate matter and discoloration before administration, whenever solution and container permit. Do not administer the drug if it contains particulate matter or discoloration; dispose of these unacceptable or unused preparations in a safe manner, in compliance with applicable regulations. 2.3 Radiation Dosimetry Subcutaneous injection to assist in lymph node localization Table 1.

Visual inspection was performed to identify the blue-labeled nodes and a hand held gamma counter was used to identify nodes concentrating the radiopharmaceutical. Multiple methods were used to detect the concentrated radioactivity within lymph nodes. For example, investigators used thresholds of background radioactivity to localize nodes containing a minimum of radioactive counts 3 times higher than the background or containing at least 10 fold higher counts than contiguous nodes. In clinical studies of patients with malignant melanoma, preoperative lymphoscintigraphy was usually performed using planar imaging techniques to establish a road map of nodal basins and to facilitate intraoperative identification of lymph nodes. [see Clinical Studies (14)] Technetium Tc 99m Sulfur Colloid Injection and other tracers may not localize all lymph nodes and the tracers may differ in their extent of lymph node localization. The lymph node localization of Technetium Tc 99m Sulfur Colloid Injection is dependent upon the underlying patency and structure of the lymphatic system, the extent of functional reticuloendothelial cells within lymph nodes and the radiopharmaceutical injection technique. Distortion of the underlying lymphatic system architecture and function by prior surgery, radiation or extensive metastatic disease may result in failure of the radiopharmaceutical and other tracers to localize lymph nodes. The use of Technetium Tc 99m Sulfur Colloid Injection is intended to supplement palpation, visual inspection and other procedures important to lymph node localization. [see Clinical Studies (14)] Peritoneo-venous (LeVeen) shunt setting in adults: Following administration of Technetium Tc 99m Sulfur Colloid Injection into the peritoneal cavity, the radiopharmaceutical mixes with the peritoneal fluid. Clearance from the peritoneal cavity varies from insignificant, which may occur with complete shunt blockage, to very rapid clearance with subsequent transfer into the systemic circulation when the shunt is patent. Following transfer into the systemic circulation, the radiopharmaceutical concentrates within the liver (a target organ). Obtain serial images of both the shunt and liver. An adequate evaluation of the difference between total blockage of the shunt and partial blockage may not be feasible in all cases. Transperitoneal absorption of sulfur colloid into the systemic circulation may occur, but it occurs slowly. Therefore, the most definitive scintigraphic evaluation of shunt patency will generally be obtained if there is visualization of both the shunt itself and the liver and/or spleen within the first three hours post intraperitoneal injection of the radiopharmaceutical. Imaging areas of functioning reticuloendothelial cells in liver, spleen or bone marrow: Altered biodistribution with lung and soft tissue uptake instead of reticuloendothelial system has been reported after intravenous injection. The size and physical-chemical properties of the sulfur colloid particles formed from the components of the kit may determine the biodistribution of the colloid and its uptake by the reticuloendothelial system. Diseases affecting the reticuloendothelial system may also alter the expected uptake pattern. Gastroesophageal and pulmonary aspiration imaging studies: To facilitate the imaging of gastroesophageal reflux consider administering Sulfur Colloid by nasogastric tube.
