Frequently Asked Questions (FAQs)

1. What is potassium iodine pills used for?

Potassium iodide is used to treat overactive thyroid and to protect the thyroid gland from the effects of radiation from inhaled or swallowed radioactive iodine.

2. Can you take iodine and potassium together?

Most iodine supplements contain potassium. Taking potassium iodide along with some medications for high blood pressure might cause too much potassium in the body. Do not take potassium iodide if you are taking medications for high blood pressure.

3. When should I take potassium iodine?

KI protects only against radioactive iodine and does not protect against other types of radiation. KI protects only the thyroid. KI does not protect other parts of the body. KI must be taken within 24 hours before or 4 hours after exposure to be most effective.

4. Is iodine potassium the same as iodine?

Potassium iodide (KI) is the same form of iodine used to iodize table salt. KI floods the thyroid with iodine, thus preventing radioactive iodine from being absorbed. If taken at the proper time, KI protects the thyroid from radioactive iodine from all sources – air, food, milk, and water.
