Q

What does Potassiume Iodine (SSKI) do for hyperthyroidism?

Think circulatory and how long it is for maximal effect

A
  • Inhibit synthesis of T3 and T4 and block their release into circulation
  • Decreases vascularity of thyroid gland, making surgery safer
    and easier
  • Maximal effect within 1-2 weeks
  • Mix with water or juice and given after meals.
  • Sipping it through a straw decreases the chance of it staining the teeth.
