Potassium Iodide 

Applications


Potassium iodide is used to loosen and break up mucus in the airways. This helps you couch up the mucus so you can breathe more easily if you have long-term lung problems (ex: asthma, chronic bronchitis, emphysema). This medication is known as an expectorant. 

Potassium iodide is also used along with anti-thyroid medicines to prepare the thyroid gland for surgical removal, to treat certain overactive thyroid conditions (hyperthyroidism), and to protect the thyroid in a radiation exposure emergency. It works by shrinking the size of the thyroid gland and decreasing the amount of thyroid hormones produced. 

In a radiation emergency, potassium iodide blocks only the thyroid from absorbing radioactive iodine, protecting it from damage and reducing the risk of thyroid cancer.
