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

Potassium iodide is also used along with antithyroid 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 number 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. Use this medication along with other emergency measures that will be recommended to you by public health and safety officials (e.g., finding safe shelter, evacuation, controlling food supply).

Light magnesium oxide is insoluble in water and ethanol, soluble in acid and ammonium salt.Magnesium is a naturally occurring mineral. Magnesium is important for many systems in the body especially the muscles and nerves.Magnesium oxide is used as a supplement to maintain adequate magnesium in the body.

Magnesium is a naturally occurring mineral. Magnesium hydroxide reduces stomach acid and increases water in the intestines which may induce bowel movements. Magnesium hydroxide is used as a laxative to relieve occasional constipation. Magnesium hydroxide is also used as an antacid to relieve indigestion, sour stomach, and heartburn. Commonly used an antacid for heartburn/indigestion or a laxative in either an oral liquid suspension or chewable tablet form. Magnesium hydroxide promotes bowel evacuation by causing osmotic retention of fluid which distends the colon with increased peristaltic activity; reacts with hydrochloric acid in the stomach to form magnesium chloride.
