The recommended oral dose for the average patient (70 kg) is 3.7 to MBq (100-400 µCi). The lower part of the dosage range MBq (100 µCi) is recommended for uptake studies alone, and the higher part MBq (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 radioactive calibration system immediately prior to administration. The capsules can be utilized up to thirty 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.
