Radioactive Iodine (I-131) is a treatment used to manage benign thyroid conditions such as Graves’ disease, toxic multinodular goiter, and toxic adenoma. I-131 emits radiation that targets thyroid cells, leading to a reduction in thyroid function, which can help alleviate symptoms of hyperthyroidism.
I-131 works by emitting two types of radiation: beta radiation, which treats the thyroid, and gamma radiation, which helps in diagnostic imaging. The iodine is absorbed by the thyroid gland, where the beta radiation works to destroy overactive thyroid tissue, helping to bring thyroid hormone levels back to normal.
I-131 treatment may be recommended for:
– Graves’ disease, either as a first-line treatment or after relapse.
– Toxic multinodular goiter, particularly if surgery is not an option.
– Toxic adenoma.
– Euthyroid goiter that causes cosmetic concerns or pressure effects.

– Pre-Treatment: Some patients may need to take antithyroid drugs (ATDs) to manage symptoms before treatment. These drugs are usually stopped a few days before the I-131 dose.
– Treatment: I-131 is administered either as a capsule or liquid. The dose may vary depending on the condition being treated.
– Post-Treatment: Most of the iodine is eliminated from the body within a few days, primarily through urine and sweat. You may need to follow specific safety precautions to minimize radiation exposure to others.
Regular follow-up appointments are crucial to monitor thyroid hormone levels. Initially, blood tests may be needed every 4-6 weeks for the first few months to adjust any necessary medication. The goal is to maintain a stable thyroid function, and sometimes, additional treatment or hormone replacement therapy may be needed.
For those with thyroid-related eye disease, the risk of eye problems worsening after I-131 treatment exists. In such cases, corticosteroids may be prescribed to reduce this risk.
The decision to undergo I-131 treatment should be made in close consultation with your healthcare provider, considering your specific medical condition, lifestyle, and personal preferences. This treatment is generally safe and effective, but it is essential to understand both the benefits and potential risks.
