Potassium Iodine is an effective antidote for the intake of radioactive iodine, a pollutant that contaminates water and food during radioactive outbreaks. It prevents radioactive iodine uptake by saturating the thyroid gland with the help of non-radioactive iodine.
Potassium iodine is prescribed as an expectorant that increases respiratory tract secretion and reduces the viscosity of the mucus.
