Radiation can come in the form of a pill. Iodine (131 I) used in thyroid treatment might be given in pill form or as a liquid. The choice is an institutional decision based on many factors, including the amount to be given to a patient.
Radioactive Iodine: This oral medication is absorbed by your thyroid gland. Radioactive iodine works by gradually destroying the thyroid. This, in turn, reduces your hyperthyroid symptoms. This treatment is effective at permanently curing hyperthyroidism, and there are very little side effects on the rest of your body. Some may require a repeat of this treatment.
