Important risk information

Warnings and precautions

  • It is essential that the user follow the directions carefully and adhere to strict aseptic procedures during preparation. Sodium pertechnetate Tc 99m solutions which contain an oxidizing agent or saline solutions containing preservatives are not suitable for use in the preparation of Technescan HDP Tc 99m.
  • Contents of the vial are intended only for use in the preparation of Technetium Tc 99m Oxidronate and are NOT to be administered directly to the patient.
  • Technetium Tc 99m Oxidronate should be formulated within eight (8) hours prior to clinical use.
  • Technetium Tc 99m Oxidronate as well as other radioactive drugs, must be handled with care, and appropriate safety measures should be used to minimize radiation exposure to the patients consistent with proper patient management and to insure minimum radiation exposure to occupational workers.
  • Radiopharmaceuticals should be used only by physicians who are qualified by specific training in the safe use and handling of radionuclides
  • To help reduce the radiation dose to the bladder, as well as other target organs, the patient should increase his or her fluid intake (unless medically contraindicated) and void as often as possible after the injection of Technetium Tc 99m Oxidronate for six hours after the imaging procedure.
  • Technetium Tc 99m Oxidronate may cause life threatening hypersensitivity reactions. Have cardiopulmonary resuscitation equipment and personnel available and monitor all patients for hypersensitivity reactions.

Adverse reactions

  • Serious adverse reactions may include hypersensitivity reactions.
  • Nausea and vomiting have infrequently been associated with Technetium Tc 99m Oxidronate.

Use in specific populations

  • Breast feeding: Should be temporarily discontinued because Technetium Tc 99m is excreted in human milk during lactation.
  • Pregnancy: Technescan HDP should not be administered to pregnant women unless it is considered that the benefits to be gained outweigh the potential hazards to the fetus.
