DRUG INTERACTIONSUSE IN SPECIFIC POPULATIONSSee 17 for PATIENT COUNSELING INFORMATION. Revised: 10/2021 |
Sodium Iodide I-131 Solution is indicated for the treatment of hyperthyroidism and selected cases of thyroid carcinoma.
Individualization of Therapy
The recommended dose for orally administered sodium iodide I 131 capsules or solution is based on the thyroid gland uptake as well as the size of the gland. Thyroidal uptake and size should be determined by the physician prior to treatment and may be useful in calculating the therapeutic dose to be administered to the individual patient.
Treatment of Hyperthyroidism
The recommended dose is 148 to 370 MBq (4 to 10 mCi) administered orally. Toxic nodular goiter may require a larger dose.
Treatment of Thyroid Carcinoma
The recommended dose is 1100 to 3700 MBq (30 to 100 mCi) administered orally. For subsequent ablation of metastases, the recommended dose is 3700 to 7400 MBq (100 to 200 mCi) administered orally.
Drug Handling
Preparation of Dilute Sodium Iodide I 131 Solution
1. Using the calibration date and radionuclidic concentration on the label of the product vial, calculate the required volume to produce the necessary dose in MBq or mCi.
2. Using a shielded syringe, remove the required volume.
3. Using the shielded syringe, transfer the required volume to a suitably shielded receiving vial.
4. Add diluent to the receiving vial to produce a final dose of the desired volume.
5. The recommended diluent is Purified Water USP containing 0.2 % sodium thiosulfate USP as a reducing agent. Acidic diluents should not be used as they may cause the pH to drop below 7.5 and stimulate the volatilization of Iodine I-131 hydriodic acid.
6. Present the dose in a shielded container for administration to the patient with a straw.
Preparation of Sodium Iodide I 131 Capsules
1. Use one large gelatin capsule and one small gelatin capsule for each dose to be prepared. Each large capsule is empty and each small capsule contains approximately 300 mg of dibasic sodium phosphate anhydrous as the absorbing buffer.
2. Using the calibration date and radionuclidic concentration on the label of the sodium iodide I-131 lead shield, calculate the required volume to produce the necessary dose in MBq or mCi.
3. Open one large capsule by pulling apart the capsule into two pieces as illustrated below:
4. Insert an unopened
small capsule into the bottom half of the empty
large capsule as illustrated below:
5. With an appropriate syringe, withdraw the required volume of sodium iodide I 131 Solution (maximum 150 microliters) from the vial as illustrated below:
6. Inject into the center of the small capsule through the top as illustrated below:
7. Slip the upper half of the large capsule over the bottom half to completely cover the small capsule and push down gently until locked as illustrated below:
8. Measure the patient dose in a suitable radioactivity calibration system immediately prior to administration.
9. Prepared capsules may be stored in a suitable polypropylene container and place inside a lead pot until use, within seven days.

Sodium Iodide I-131 is contraindicated in:
Sodium iodide I 131 may cause thyroiditis with release of thyroid hormone, which may aggravate hyperthyroidism and thyrotoxic cardiac disease [see Adverse Reactions (6)] . When treating hyperthyroidism, consider pre-treatment anti-thyroid medication to help deplete the thyroid hormone. Discontinue the anti-thyroid therapy three days before administration of sodium iodide I 131 [see Drug Interactions (7)] . Consider a beta-blocker pre or post-treatment to minimize the risk of hyperthyroidism and thyroid storm.
The thyroiditis may cause gland enlargement resulting in tenderness and swelling of the neck, pain on swallowing, sore throat, and cough; which may occur approximately the third day after sodium iodide I 131 administration. Consider management with pain-reliever or anti-inflammatory medications.
Sodium Iodide I 131 may cause radiation induced toxicities [see Adverse Reactions (6)] :
Obtain a complete blood count within one month of therapy. If patients show leukopenia or thrombocytopenia, dosimetry should be used to determine a safe sodium iodide I 131 activity, while delivering less than 2 Gy to the bone marrow.
Advise good hydration for one week following sodium iodide I 131 administration and stimulate salivary flow via a sialagogue (e.g. sugar-free candy or gum, pilocarpine, and ascorbic acid) to reduce radiation exposure to the salivary glands.
Advise patients to void frequently after administration of radioiodide to enhance excretion.
Hypersensitivity reactions including anaphylaxis may occur in patients who receive sodium iodide I 131. Although iodide is not considered an allergen, hypersensitivity reactions may occur in relation with excipients or chemical component of the capsule, such as sodium thiosulfate. Obtain and document an allergy history, particularly a sulfite allergy. Emergency resuscitation equipment and personnel should be immediately available [see Adverse Reactions (6)] .
Sodium Iodide I-131 Solution is contraindicated in pregnancy because sodium iodide I-131 crosses the placenta and fetal exposure can lead to neonatal hypothyroidism. Multiple reports in the published literature describe hypothyroidism in the neonates following in utero exposure to sodium iodide I-131. Some cases of neonatal hypothyroidism were severe and irreversible. Verify pregnancy status of females of reproductive potential prior to initiating Sodium Iodide I-131 Solution treatment. Advise females and males of reproductive potential to use effective contraception during treatment with Sodium Iodide I-131 Solution and for at least six months after the last dose [see Use in Specific Populations (8.1, 8.3)].
Sodium Iodide I-131 Solution is contraindicated in lactating women because sodium iodide I-131 concentrates in the breast via the increased expression of the sodium iodide symporter in breast tissue with lactation. The literature describes moderate to marked radioiodine uptake in the breast tissue for 5 to 32 weeks post cessation of breast feeding. Advise lactating women to discontinue breast feeding at least 6 weeks prior to administration of sodium iodide I-131 to allow sufficient time for involution to occur and to avoid excess concentration of sodium iodide I-131 in breast tissue. Consider administration of drugs to suppress lactation. Consider diagnostic scintigraphy before administration of sodium iodide I-131 to assess the persistence of uptake by breast tissue. If sodium iodide I-131 is administered in the postpartum period, the lactating mother should not breastfeed the infant [see Use in Specific Populations (8.2)] .
Transient dose-related impairment of testicular function in men and transient ovarian insufficiency in women has been reported after sodium iodide I-131 therapy. Sperm banking for men may be considered prior to administration of Sodium Iodide I-131 Solution for thyroid carcinoma [see Use in Specific Populations (8.3)] .
Household Contacts
Instruct patients to follow radiation safety precautions after receiving Sodium Iodide I-131 to minimize the radiation contamination of other persons or the environment. Patients should avoid close contact with others, especially pregnant women and children, and take care to avoid contamination of other persons or the environment with body fluids.
Patients and Healthcare Providers
Sodium Iodide I-131
contributes to a patient’s overall long-term cumulative radiation exposure, which is associated with an increased risk of cancer. Follow safe handling and administration to minimize radiation exposure to the patient and healthcare providers.
Certain food or drugs may alter the thyroid uptake of sodium iodide I 131 and diminish its effectiveness. Recent intake of stable iodide in any form, or the use of thyroid or anti-thyroid drugs may diminish thyroid uptake of sodium iodide I 131 [see Drug Interactions (7)] .
The following clinically significant adverse reactions are described below and elsewhere in labeling:
The following adverse reactions have been reported during post-approval use of sodium iodide I-131 (Table 3). Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Risk Summary
Sodium Iodide I-131 is contraindicated in pregnancy because fetal exposure can lead to neonatal hypothyroidism, which in some cases is severe and irreversible
[see
Warnings and Precautions (5.4)]
. Data from the published literature describe thyroid abnormalities after fetal exposure; including agenesis of the thyroid and hypothyroidism (see
Data). No animal reproductive studies have been conducted.
Clinical Considerations.
Fetal/ Neonatal Adverse Reactions
A fetus exposed to sodium iodide I 131 can develop neonatal hypothyroidism. Delay in diagnosis of neonatal hypothyroidism after exposure to sodium iodide I 131 in utero can result in severe sequelae such as decreased mental capacity and delayed bone age. Monitor thyroid function in any infant born after in utero exposure to sodium iodide I 131.
Data
Human Data
Sodium iodide I 131 crosses the placenta and the fetal thyroid begins to concentrate iodide during the 10-12
th week of gestation. In literature reports of maternal exposures to sodium iodide I 131 at doses of 333 – 8325 MBq (9 – 225 mCi) during 4-26 weeks gestational age, the most common adverse outcomes were hypothyroid infants and children.
Risk Summary
Sodium Iodide I-131 Solution is contraindicated during lactation because I-131 concentrates in the breast during lactation via the increased expression of the sodium iodide symporter in breast tissue and can lead to hypothyroidism in the infant through breastfeeding. If sodium iodide I-131 is administered postpartum, breastfeeding should not be restarted for the remainder of the postpartum period. In addition, to minimize the absorbed radiation dose to the breast tissue, breastfeeding and breast-pumping should be discontinued for at least 6 weeks before administration of sodium iodide I-131
[see
Warnings and Precautions (5.5)]
. Infants exposed to sodium iodide I-131 through breast milk are at risk for development of hypothyroidism because sodium iodide I-131 is distributed into breast milk and may reach concentrations equal to or greater than concentrations in maternal plasma(see
Data).
Data
Published literature describes sodium iodide I-131 transfer into breast milk and uptake by the thyroid of the breastfed infant. The amount of sodium Iodide I-131 detected in the breast milk at 36 to 48 hours after administration is 1% to 27% of the injected dose (with injected doses between 1.1 MBq to 5,143 MBq).
Sodium Iodide I-131 is contraindicated in pregnancy because of the risk of fetal hypothyroidism [see Warnings and Precautions (5.4) and [see Use in Specific Populations (8.1)] .
Pregnancy Testing
Obtain a pregnancy test in females of reproductive potential and verify the absence of pregnancy before initiating treatment [see
Dosage and Administration (2.2)].
Contraception
Advise females and males of reproductive potential to use effective contraception during treatment with Sodium Iodide I-131 Solution and for at least six months after the last dose of Sodium Iodide I-131 Solution.
Infertility
Females
Fertility may be impaired with Sodium Iodide I-131 Solution treatment. Transient amenorrhea and ovarian insufficiency have been observed after sodium iodide I-131 therapy in females. The literature describes reports of transient menstrual cycle irregularities, including amenorrhea, and ovarian failure in females treated with cumulative doses of 1,000 MBq to 59,000 MBq (27 mCi to 1,595 mCi) sodium iodide I-131. In a published literature analysis, the effects on fertility occurred in up to 30% of women treated with sodium iodide I-131, and may resolve 12 months after treatment.
Males
Fertility may be impaired with Sodium Iodide I-131 Solution treatment. Discuss sperm banking for males who are expected to receive a high cumulative dose of sodium iodide I-131. Transient dose-related impairment of testicular function after sodium iodide I-131 therapy has been reported in the published literature. The literature describes reports of males treated with sodium iodide I-131 at doses of 370 MBq to 22,000 MBq (10 mCi to 595 mCi) resulting in transiently impaired testicular function (including spermatogenesis). The risk of persistent testicular dysfunction increases after administration of repeated or high cumulative radioiodide exposure.
The safety and effectiveness of Sodium Iodide I-131 Solution have not been established in pediatric patients. Pediatric patients are at an increased lifetime risk for malignancy from radiation exposure.
Clinical experience has not identified differences in safety or effectiveness in geriatric patients compared to younger patients. However, elderly patients are more likely to have decreased renal function and radiation exposure is greater in patients with impaired renal function [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
Sodium Iodide I 131 is primarily excreted by the kidneys. Renal function impairment decreases excretion of sodium iodide I 131 and increases the radiation exposure and risk of radiation toxicity. For patients with a history of renal impairment, evaluate renal function for therapeutic planning and consider dosimetry. Sodium Iodide I 131 is dialyzable. Hemodialysis can be used to reduce total body radiation exposure [see Clinical Pharmacology (12.3)].
In case of exposure to a radioactive dose of sodium iodide I 131 exceeding the intended therapeutic dose, provide general supportive care, promote frequent voiding, monitor for bone marrow and thyroid suppression. Consider administering a thyroid blocking agent (e.g. potassium iodide (KI) or perchlorate) promptly within 4 to 6 hours after the exposure. Assess the benefit of administering a thyroid blocking agent against the risk of failure of sodium iodide I 131 therapy. Appropriate replacement therapy is recommended if hypothyroidism occurs.
Sodium Iodide I-131 Solution, a radioactive therapeutic agent, provides a concentrated solution of sodium iodide I-131 with a radioconcentration of 37,000 MBq/mL (1,000 mCi/mL). Each mL of the concentrated solution contains 37,000 MBq of no-carrier-added sodium iodide I-131, disodium edetate dihydrate USP as a stabilizer, sodium thiosulfate pentahydrate USP as a reducing agent, and dibasic sodium phosphate anhydrous USP. The pH of the concentrated solution is between 7.5 and 10.
The concentrated solution provided with Sodium Iodide I-131 Solution is used for the preparation of sodium iodide I-131 capsules or sodium iodide I-131 solution of varying strengths for oral administration for therapy.
Sodium iodide I-131 solution is designated chemically as Na 131I and has a molecular weight of 153.99 g/mol. Hard gelatin capsules, provided for the preparation of the sodium iodide I-131 capsules final dosage form, contain approximately 300 mg of dibasic sodium phosphate anhydrous USP as the absorbing buffer.
Iodine I-131 decays by beta emission and associated gamma emission with a physical half-life of 8.02 days. The principal radiation emissions are listed in Table 5.
Radiation | Mean % per
Disintegration | Mean Energy
(keV) |
Beta-1 | 2.1% | 69.4 |
Beta-3 | 7.2% | 96.6 |
Beta-4 | 89.4% | 191.6 |
Gamma-7 | 6.1% | 284.3 |
Gamma-14 | 81.2% | 364.5 |
Gamma-18 | 7.1% | 637.0 |
The specific gamma-ray constant for iodide I 131 is 4.26 × 10 -13 C·m 2·kg -1·MBq -1·s -1 (2.2 R·cm 2/mCi·hr). The first half-value thickness of lead (Pb) for iodide I 131 is 0.27 cm. A range of values for the relative attenuation of the radiation emitted by iodide I 131 that results from interposition of various thicknesses of Pb is shown in Table 6. For example, the use of 2.59 cm of Pb will decrease the external radiation exposure by a factor of about 1,000.

Iodide is actively transported by the sodium-iodide symporter (NIS) protein, in thyroid follicular cells. Iodide is concentrated in follicular cells to levels up to 50 times higher than in the plasma. Iodide is metabolically oxidized by thyroid peroxidase to iodinium (I +) which in turn iodinates tyrosine residues of thyroglobulin (tri or tetra-iodinated tyrosine). The beta emission of I 131 is responsible for the therapeutic effect.
The relationship between the extent of iodide I 131 exposure and pharmacologic effects has not been explored in clinical trials.
Absorption
Following oral administration of sodium iodide I 131, 90% of the administered radioactivity of Iodide I 131 is systemically absorbed in the first 60 minutes.
Distribution
Following absorption, I 131 is distributed within the extra-cellular space. It is actively transported by the sodium-iodide symporter (NIS) protein, and binds to thyroglobulin resulting in accumulation in the thyroid. The thyroid uptake of iodide is usually increased in hyperthyroidism and in goiter, and is decreased in hypothyroidism. Sodium Iodide I 131 also accumulates in the stomach, choroid plexus, salivary glands, breast, liver, gall bladder, and kidneys.
Elimination
Metabolism
In thyroidal follicular cells iodide is oxidized through the action of thyroid peroxidase to iodinium (I
+) which in turn iodinates tyrosine residues of thyroglobulin.
Excretion
Sodium iodide I 131 is excreted in urine and feces. The normal range of urinary excretion is 37% to 75% of the administered dose, varying with the thyroid and renal function of the patient. Fecal excretion is about 10%.
The Sodium Iodide I-131 Solution provides a concentrated solution of sodium iodide I-131 with a radioconcentration of 37,000 MBq/mL (1,000 mCi/mL) at the time of calibration and can be supplied in any of the following vials: 1, 2 and 3 mL clear glass V-vials.
The concentrated solution is intended for use in the preparation of capsules and solutions of varying strengths for oral administration.
