About Ultratag RBC

What is this medication?

Ultratag RBC is a specialized prescription kit used in nuclear medicine to prepare radiolabeled red blood cells for diagnostic imaging procedures. The kit contains chemicals, specifically stannous chloride, that prepare a patient's own red blood cells to bond with a radioactive isotope called technetium Tc 99m. Once the blood cells are labeled, they are reinjected into the patient so that specialized cameras can track the movement and distribution of blood throughout the body.

This medication is primarily used to perform blood pool imaging studies, which help physicians evaluate the heart's pumping function through a procedure known as a MUGA scan. It is also frequently utilized to locate the source of internal gastrointestinal bleeding or to image the spleen. By using the patient's own cells as a carrier for the radioactive tracer, doctors can obtain clear images of the circulatory system and identify various cardiovascular or internal abnormalities.

Indications and usage
INDICATIONS AND USAGE Technetium Tc 99m red blood cells are used for blood pool imaging, including cardiac first pass and gated equilibrium imaging and for detection of sites of gastrointestinal bleeding.
Dosage and administration
DOSAGE AND ADMINISTRATION The Instructions for Preparation must be carefully followed for preparing technetium Tc 99m red blood cells using Ultratag™ RBC. The suggested dose range of technetium Tc 99m red blood cells in the average patient (70 kg) is 370 MBq (10 mCi) to 740 MBq (20 mCi). The patient dose should be measured by a suitable radioactivity calibration system immediately prior to administration. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Aseptic procedures and a shielded syringe should be employed in preparing and withdrawing doses for administration to patients. The user should wear waterproof gloves during the administration procedure.
Contraindications
CONTRAINDICATIONS None known.
Warnings
WARNINGS None known.
Adverse reactions
ADVERSE REACTIONS None known.
Use in pregnancy
Pregnancy Animal reproduction studies have not been conducted with technetium Tc 99m red blood cells. It is also not known whether this drug can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Technetium Tc 99m red blood cells should be administered to a pregnant woman only if clearly needed. Ideally, examinations using radiopharmaceuticals, especially those elective in nature, of a woman of childbearing capability should be performed during the first few (approximately 10) days following the onset of menses.
