Nausea, vomiting, stomach ache, diarrhea, metallic taste in the mouth, fever, headache, or acne may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Is potassium iodide harmful to the body?

This is known as internal contamination. When the thyroid absorbs high levels of radioactive iodine, it can increase the risk of thyroid cancer in infants, children, and young adults many years after exposure. The thyroid is a gland in the neck that plays an important role in many body functions.

Can you take potassium iodide daily?

Take this medicine only when directed to do so by state or local public health authorities. Take this medicine once daily until the risk of significant exposure to radiation no longer exists.Do not take more of it and do not take it more often than directed.

What is potassium iodide medication used for?

Potassium iodide is used to protect the thyroid gland from taking in radioactive iodine that may be released during a nuclear radiation emergency. Radioactive iodine can damage the thyroid gland.

How long can you take potassium iodide?

KI is helpful for about 24 hours. You should keep taking it once a day until the health department says to stop, or you are out of the emergency area.

Is potassium iodide 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.

How can I protect my thyroid from radiation?

Uptake of radioactive iodine may increase the risk of thyroid cancer, particularly in children. The younger the age at exposure, the higher the risk is for developing thyroid cancer. In this situation, potassium iodide is used to protect, or block, the thyroid from irradiation.

What does radiation do to the body?

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.

What is the difference between iodine and potassium iodide?

Iodine and potassium iodide are two different chemicals that are used in many applications. The first difference is the chemical structure of both items. Iodine is an element and has an atomic number. On the other hand, potassium iodide is a compound (or a mixture of two elements).

Can you have too much iodide?

Can iodine be harmful? Yes, if you get too much. Getting high levels of iodine can cause some of the same symptoms as iodine deficiency, including goiter (an enlarged thyroid gland). High iodine intakes can also cause thyroid gland inflammation and thyroid cancer.
