Sodium Iodide

Introduction

Sodium Iodide is a chemical compound of iodine used in both diagnostic and therapeutic medical applications. It is commonly used to treat or prevent iodine deficiency and in the management of thyroid-related disorders. Sodium Iodide plays a vital role in thyroid hormone production, which regulates metabolism and energy. It is also utilized in imaging and treatment of thyroid diseases, including thyroid cancer and hyperthyroidism, especially in radioactive form.

Uses of Sodium Iodide

• Treatment and prevention of iodine deficiency
• Management of goiter
• Radioactive iodine therapy for hyperthyroidism
• Radioactive iodine therapy for thyroid cancer
• Thyroid function diagnostic scans
• Adjunct therapy with antithyroid medications

How Sodium Iodide Works

Sodium Iodide works by supplying the body with iodine, an essential element for producing thyroid hormones. In its radioactive form, it accumulates in the thyroid gland and emits radiation that destroys overactive thyroid cells or cancerous tissue, making it valuable in treating certain thyroid disorders.

Benefits of Sodium Iodide

• Effectively treats iodine deficiency
• Supports healthy thyroid function
• Helps reduce goiter and thyroid swelling
• Non-invasive treatment for hyperthyroidism
• Targets thyroid cancer cells with minimal damage to other tissues

How to Take Sodium Iodide

Sodium Iodide is usually taken orally, either in tablet or solution form. The dosage depends on the condition being treated, the patient’s age, and whether it’s a therapeutic or diagnostic use. In the case of radioactive iodine therapy, it is administered in a controlled medical setting. Always follow the doctor’s prescription and safety instructions.

Type of Dosage Available

• Oral tablets
• Oral solution
• Radioactive oral capsule (for diagnostic or therapeutic use)

Side Effects of Sodium Iodide

• Nausea or stomach upset
• Metallic taste in mouth
• Swelling of salivary glands
• Allergic reactions (rash, itching)
• Temporary neck tenderness
• Reduced thyroid function (hypothyroidism after treatment)

Safety Advice

• Not recommended for pregnant or breastfeeding women (especially radioactive form)
• Avoid close contact with others after radioactive iodine therapy
• Inform your doctor about any existing thyroid conditions
• Follow a low-iodine diet if advised before treatment
• Regular monitoring of thyroid hormone levels is essential
