Thallous chloride tl-201

Administration and Imaging Instructions Patient Preparation Instruct patients to hydrate before and after Thallous Chloride Tl 201 Injection administration and to void before imaging and frequently thereafter following Thallous Chloride Tl 201 Injection administration [see Warnings and Precautions] . Administration Use aseptic technique and radiation shielding when withdrawing and administering Thallous Chloride Tl 201 Injection.

Visually inspect the drug for particulate matter and discoloration prior to administration, whenever the solution and container permit. Do not use if contents are turbid or discolored. Measure the patient dose with a dose calibrator immediately prior to administration. Use within 6 days from the manufacturer’s calibration date or 9 days from the date of manufacture, whichever comes first.

Dispose of unused products in a safe manner in compliance with applicable regulations. Myocardial Perfusion Imaging For resting myocardial studies, begin imaging 10 minutes to 20 minutes after administration of Thallous Chloride Tl 201 Injection. Target-to-background ratios are improved when patients are injected upright and in the fasting state; the upright position reduces the hepatic and gastric thallium-201 concentration.

For exercise stress testing, administer Thallous Chloride Tl 201 Injection at the start of a period of maximum stress, which is sustained for approximately 30 seconds after injection. Begin imaging within 10 minutes after administration to obtain maximum target-to-background ratios. Within 2 hours after the completion of the stress testing, the target-to-background ratios may decrease in lesions that are attributable to transient ischemia.

Parathyroid Hyperactivity Localization For localization of parathyroid hyperactivity, administer Thallous Chloride Tl 201 Injection before, with, or after a minimal dose of a thyroid imaging agent such as sodium pertechnetate Tc 99m injection or sodium iodide I 123 capsules to enable thyroid subtraction imaging.
