Usage information

Dosing and administration
2 DOSAGE AND ADMINISTRATION Fludeoxyglucose F-18 Injection emits radiation. Use procedures to minimize radiation exposure. Calculate the final dose from the end of synthesis (EOS) time using proper radioactive decay factors. Assay the final dose in a properly calibrated dose calibrator before administration to the patient [see Description (11.2)]. Fludeoxyglucose F-18 Injection emits radiation. Use procedures to minimize radiation exposure. Screen for blood glucose abnormalities. •In the oncology and neurology settings, instruct patients to fast for 4 – 6 hours prior to the drug’s injection. Consider medical therapy and laboratory testing to assure at least two days of normoglycemia prior to the drug’s administration (5.2). •In the cardiology setting, administration of glucose-containing food or liquids (e.g., 50 – 75 grams) prior to the drug’s injection facilitates localization of cardiac ischemia (2.3). Aseptically withdraw Fludeoxyglucose F-18 Injection from its container and administer by intravenous injection (2). The recommended dose: •for adults is 5 – 10 mCi (185 – 370 MBq), in all indicated clinical settings (2.1). •for pediatric patients is 2.6 mCi in the neurology setting (2.2). Initiate imaging within 40 minutes following drug injection; acquire static emission images 30 – 100 minutes from time of injection (2). 2.1 Recommended Dose for Adults Within the oncology, cardiology and neurology settings, the recommended dose for adults is 5 – 10 mCi (185 – 370 MBq) as an intravenous injection. 2.2 Recommended Dose for Pediatric Patients Within the neurology setting, the recommended dose for pediatric patients is 2.6 mCi, as an intravenous injection. The optimal dose adjustment on the basis of body size or weight has not been determined [see Use in Special Populations (8.4)]. 2.3 Patient Preparation •To minimize the radiation absorbed dose to the bladder, encourage adequate hydration. Encourage the patient to drink water or other fluids (as tolerated) in the 4 hours before their PET study. •Encourage the patient to void as soon as the imaging study is completed and as often as possible thereafter for at least one hour. •Screen patients for clinically significant blood glucose abnormalities by obtaining a history and/or laboratory tests [see Warnings and Precautions (5.2)]. Prior to Fludeoxyglucose F-18 PET imaging in the oncology and neurology settings, instruct patient to fast for 4 – 6 hours prior to the drug’s injection. •In the cardiology setting, administration of glucose-containing food or liquids (e.g., 50 – 75 grams) prior to Fludeoxyglucose F-18 Injection facilitates localization of cardiac ischemia. 2.4 Radiation Dosimetry The estimated human absorbed radiation doses (rem/mCi) to a newborn (3.4 kg), 1-year old (9.8 kg), 5-year old (19 kg), 10-year old (32 kg), 15-year old (57 kg), and adult (70 kg) from intravenous administration of Fludeoxyglucose F-18 Injection are shown in Table 1. These estimates were calculated based on human2 data and using the data published by the International Commission on Radiological Protection4 for Fludeoxyglucose 18F. The dosimetry data show that there are slight variations in absorbed radiation dose for various organs in each of the age groups. These dissimilarities in absorbed radiation dose are due to developmental age variations (e.g., organ size, location, and overall metabolic rate for each age group). The identified critical organs (in descending order) across all age groups evaluated are the urinary bladder, heart, pancreas, spleen, and lungs. Table 1. Estimated Absorbed Radiation Doses (rem/mCi) After Intravenous Administration of Fludeoxyglucose F-18 Injectiona Organ Newborn (3.4 kg) 1-year old (9.8 kg) 5-year old (19 kg) 10-year old (32 kg) 15-year old (57 kg) Adult (70 kg) a MIRDOSE 2 software was used to calculate the radiation absorbed dose.
