WARNING: HIGH LEVEL RADIATION EXPOSURE WITH USE OF INCORRECT ELUENT AND FAILURE TO FOLLOW THE ELUATE TESTING PROTOCOL

High Level Radiation Exposure with Use of Incorrect Eluent

Patients are exposed to high radiation levels when the CardioGen-82 generator is eluted with the incorrect eluent due to high Sr 82 and Sr 85 breakthrough levels.

• Use only additive-free 0.9% Sodium Chloride Injection USP to elute the generator
• If an incorrect solution is used to elute CardioGen-82:
  
  • Immediately stop the patient infusion;
  • Evaluate the patient’s radiation absorbed dose and monitor for the effects of radiation to critical organs such as bone marrow;
  • Permanently discontinue use of the affected generator.

Excess Radiation Exposure with Failure to Follow the Eluate Testing Protocol

Excess radiation exposure occurs when the levels of Sr 82 or Sr 85 in the rubidium Rb 82 chloride injection exceed specified limits.

• Record each generator eluate volume, including waste and test volumes, and keep a record of the cumulative eluate volume
• Strictly adhere to the generator eluate testing protocol, to minimize the risk of excess radiation exposure, including daily testing and additional testing at Alert Limits
• Stop using the generator if it reaches any of its Expiration Limits: 17 L for the generator’s cumulative eluate volume, or 42 days post generator calibration date, or an eluate Sr 82 level of 0.01 μCi /mCi Rb 82, or an eluate Sr 85 level of 0.1 μCi /mCi Rb 82

WARNINGS AND PRECAUTIONS

High Level Radiation Exposure with Use of Incorrect Eluent

Use only additive free 0.9% Sodium Chloride Injection USP to elute the generator. Apply the provided saline tag to the additive free 0.9% Sodium Chloride Injection USP container before use. Additives present in other solutions (particularly calcium ions) expose patients to high levels of radiation by causing the release of large amounts of Sr 82 and Sr 85 into the eluate regardless of the generator’s age or prior use. Immediately stop the patient infusion and discontinue use of the affected CardioGen-82 generator if the incorrect eluent is used and evaluate the patient’s radiation absorbed dose and monitor for the effects of radiation to critical organs such as bone marrow.

Excess Radiation Exposure with Failure to Follow Testing Protocol

Excess radiation exposure occurs when the Sr 82 and Sr 85 levels in rubidium Rb 82 chloride injections exceed the specified generator eluate limits. Strictly adhere to the eluate testing protocol to minimize radiation exposure to the patient. Stop using the rubidium generator when the expiration limits are reached.

Risk Associated with Pharmacologic Stress

Pharmacologic induction of cardiovascular stress may be associated with serious adverse reactions such as myocardial infarction, arrhythmia, hypotension, bronchoconstriction, and cerebrovascular events. Perform pharmacologic stress testing in accordance with the pharmacologic stress agent’s prescribing information and only in the setting where cardiac resuscitation equipment and trained staff are readily available.

Cumulative Radiation Exposure: Long-Term Risk of Cancer

Rubidium Rb 82 chloride injection, similar to other radiopharmaceuticals, contributes to a patient’s overall long-term cumulative radiation exposure which is associated with an increased risk of cancer. Use the lowest dose of rubidium Rb 82 chloride injection necessary for imaging and ensure safe handling to protect the patient and health care worker. Encourage patients to void as soon as a study is completed and as often as possible thereafter for at least one hour.

ADVERSE REACTIONS

Radiation Exposure

High level radiation exposure to the bone marrow has occurred in some patients due to Sr 82 and Sr 85 breakthrough in the eluate when an incorrect solution was used to elute the rubidium Rb 82 generator. Excess radiation exposure has occurred in some patients who received rubidium Rb 82 chloride injections at clinical sites where generator eluate testing appeared insufficient.
