High Thyroid Hormone Radioactive Iodine
Treatment with radioactive iodine is the most common therapy for hyperthyroidism.
Lugol's solution contains a mixture of radioactive iodine. After an oral dose, radioactive iodine is absorbed by the thyroid and destroys the overactive cells in the thyroid. Thyroid hormone levels often return to normal within 6 to 12 weeks. In some cases it may take 4 to 6 months before the hormone levels decrease. Repeat treatments may be necessary.
