🎯 Indications and Usage ▾
INDICATIONS AND USAGE Administration of Sodium Iodide I 123 Capsules is indicated as a diagnostic procedure to be used in evaluating thyroid function and/or morphology.
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION The recommended oral dose for the average patient (70 kg) is 3.7 to
14.8MBq (100 to 400 μCi). The lower part of the dosage range
3.7 MBq (100 μCi) is recommended for uptake studies alone, and the higher part
14.8MBq (400 μCi) for thyroid imaging. The determination of I-123 concentration in the thyroid gland may be initiated at six hours after administering the dose and should be measured in accordance with standardized procedures. The patient dose should be measured by a suitable radioactivity calibration system immediately prior to administration.
The capsules can be utilized up to 30 hours after calibration time and date. Thereafter, discard the capsules in accordance with standard safety procedures. The user should wear waterproof gloves at all times when handling the capsules or container.
Radiation Dosimetry The estimated absorbed radiation doses to several organs of an average patient (70 kg) from oral administration of the maximum dose of
14.8MBq (400 μCi) of I-123 are shown in Table 4 for thyroid uptakes of 5, 15, and 25%. For comparison at these three values of thyroid uptake, the estimated radiation doses from doses of
3.7MBq (100 μCi) I-131, also used as thyroid imaging agent, are also included. Table 4.

⛔ Contraindications ▾
CONTRAINDICATIONS To date there are no known contraindications to the use of Sodium Iodide I 123 Capsules.
⚠️ Warnings ▾
WARNINGS Females of childbearing age and pediatric patients should not be studied unless the benefits anticipated from the performance of the test outweigh the possible risk of exposure to the amount of ionizing radiation associated with the test.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS Although rare, reactions associated with the administration of sodium iodide isotopes for diagnostic use include, in decreasing order of frequency, nausea, vomiting, chest pain, tachycardia, itching skin, rash and hives.
🤰 Pregnancy ▾
Pregnancy Category C Animal reproduction studies have not been conducted with this drug. It is also not known whether sodium iodide I-123 can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Sodium iodide I-123 should be given to a pregnant woman only if clearly needed.
Ideally, examinations using radiopharmaceuticals, especially those elective in nature, in women of child-bearing capability should be performed during the first few (approximately ten) days following the onset of menses.
🧒 Pediatric Use ▾
Pediatric Use Safety and effectiveness in pediatric patients have not been established.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Sodium iodide I-123 is readily absorbed from the upper gastrointestinal tract. Following absorption, the iodide is distributed primarily within the extracellular fluid of the body. It is trapped and organically bound by the thyroid and concentrated by the stomach, choroid plexus and salivary glands.
It is excreted by the kidneys. The fraction of the administered dose which is accumulated in the thyroid gland may be a measure of thyroid function in the absence of unusually high or low iodine intake or administration of certain drugs which influence iodine accumulation by the thyroid gland. Accordingly, the patient should be questioned carefully regarding previous medications and/or procedures involving radiographic media.
Normal subjects can accumulate approximately 10 to 50% of the administered iodine dose in the thyroid gland, however, the normal and abnormal ranges are established by individual physician's criteria. The mapping (imaging) of sodium iodide I-123 distribution in the thyroid gland may provide useful information concerning thyroid anatomy and definition of normal and/or abnormal functioning of tissue within the gland.

📋 Description ▾
DESCRIPTION Sodium Iodide I 123 (Na 123 I) for diagnostic use is supplied in capsules for oral administration. The capsules are available in strengths of 3.7 and 7.4 megabecquerels (MBq) (100 and 200 μCi) I-123 at time of calibration. The radionuclidic composition at calibration is not less than 97.0 percent I-123, not more than 2.9 percent I-125 and not more than 0.1 percent Te-121.
The radionuclidic composition at expiration time is not less than 87.2 percent I-123, not more than 12.4 percent I-125 and not more than 0.4 percent Te-121. The ratio of the concentration of I-123 and I-125 changes with time. Graph 1 shows the minimum concentration of I-123 as a function of time and Graph 2 shows the maximum concentration of I-125 as a function of time.

Principal Radiation Emission Data Radiation Mean % Disintegration Energy (keV) Gamma-2 83.4 159 External Radiation The specific gamma ray constant for I-123 is
1.6R/hr-mCi at 1 cm. The first half-value thickness of lead (Pb) for I-123 is 0.005 cm. A range of values for the relative attenuation of the radiation emitted by this radionuclide that results from the interposition of various thicknesses of Pb is shown in Table 2.
For example, the use of 1.63 cm of lead will decrease the external radiation exposure by a factor of about 1,000. Table 2.
