Sodium iodide I-131 uses, doses, brand name and effects
Des: Sodium iodide I-131 is a radioactive isotope of iodine that is used for medical purposes, such as in the diagnosis and treatment of thyroid disorders, including hyperthyroidism and thyroid cancer. It is administered orally in the form of a capsule or liquid.
Some common uses of sodium iodide I-131 include:
- Radioiodine therapy for thyroid cancer: This involves administering a high dose of sodium iodide I-131 to destroy any remaining thyroid tissue after surgery, or to treat metastatic thyroid cancer that has spread to other parts of the body.
- Radioiodine therapy for hyperthyroidism: This involves administering a lower dose of sodium iodide I-131 to destroy overactive thyroid tissue and reduce the production of thyroid hormones.
- Diagnostic imaging: This involves administering a small, safe dose of sodium iodide I-131 to allow doctors to visualize the thyroid gland using a special camera.
The dose of sodium iodide I-131 depends on the purpose of the treatment and the patient’s condition. For example, a typical dose for radioiodine therapy for thyroid cancer is usually between 100 and 200 millicuries (mCi), while a typical dose for radioiodine therapy for hyperthyroidism is usually between 5 and 30 mCi.
Sodium iodide I-131 is usually sold under the brand names Iodotope and Sodium Iodide I-131. It is a radioactive substance and can have some side effects, such as nausea, vomiting, and dry mouth. It is important to follow all instructions provided by the healthcare provider when using this medication.
It is worth noting that sodium iodide I-131 is a radioactive substance that can have long-term effects on the body, including an increased risk of developing cancer. Patients who receive this treatment should be monitored regularly by their healthcare provider.
