Technetium Tc-99m
Generic Name: technetium tc-99m
Brand Names:
Ultra-technekow V4
DESCRIPTION The Ultra-Technekow ™ V4 Generator is prepared with fission-produced molybdenum Mo-99 adsorbed onto alumina in a column shielded by lead, tungsten, or depleted uranium. The column assembly and shielding are encased in a plastic container that is covered with a plastic elution hood. The elution hood has an opening for the column assembly double inlet needles and an opening for the single outlet needle.

Uses
INDICATIONS AND USAGE The Ultra-Technekow™ V4 generator is a source of sodium pertechnetate Tc 99m for use in the preparation of FDA-approved diagnostic radiopharmaceuticals, as described in the labeling of these diagnostic radiopharmaceutical kits. Sodium Pertechnetate Tc 99m is used IN ADULTS as an agent for: Thyroid Imaging Salivary Gland Imaging Urinary Bladder Imaging (direct isotopic cystography) for detection of vesico-ureteral reflux Nasolacrimal Drainage System Imaging (dacryoscintigraphy) Sodium Pertechnetate Tc 99m is used IN PEDIATRIC PATIENTS as an agent for: Thyroid Imaging Urinary Bladder Imaging (direct isotopic cystography) for the detection of vesico-ureteral reflux
Dosage
DOSAGE AND ADMINISTRATION Sodium Pertechnetate Tc 99m is administered by intravenous injection. When imaging the nasolacrimal drainage system, instill the Sodium Pertechnetate Tc 99m by the use of a device such as a micropipette or similar method which will ensure the accuracy of the dose. For imaging the urinary bladder and ureters (direct isotopic cystography), the Sodium Pertechnetate Tc 99m is administered by direct instillation aseptically into the bladder via a urethral catheter, following which the catheter is flushed with approximately 200 mL of sterile saline directly into the bladder.
Side Effects
ADVERSE REACTIONS Allergic reactions including anaphylaxis have been reported infrequently following the administration of Sodium Pertechnetate Tc 99m.
Warnings
WARNINGS Radiation risks associated with the use of Sodium Pertechnetate Tc 99m are greater in pediatric patients than in adults and, in general, the younger the patient the greater the risk owing to greater absorbed radiation doses and longer life expectancy. These greater risks should be taken firmly into account in all benefit risk assessments involving pediatric patients. Long-term cumulative radiation exposure may be associated with an increased risk of cancer. Only use generator eluant specified for use with the Ultra-Technekow ™ V4 Generator. Do not use any other generator eluant or saline from any other source. CONTRAINDICATIONS None.
Pregnancy
Pregnancy In animal reproductive studies, Sodium Pertechnetate Tc 99m (as free pertechnetate) has been shown to cross the placental barrier. It is not known whether Sodium Pertechnetate Tc 99m can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Sodium Pertechnetate Tc 99m should be given to pregnant women only if the expected benefits to be gained clearly outweigh the potential hazards.
Storage
HOW SUPPLIED The Ultra-Technekow ™ V4 (Technetium Tc 99m) Generators contain the following amount of molybdenum Mo-99 at the date and time of calibration stated on the label. Catalog No.
