Potassium iodide is indicated as a thyroid-blocking agent to prevent the uptake of radioactive iodine, for example after a nuclear accident or during a nuclear medicine investigation before administering a radioiodinated compound, which is metabolised to iodide or which contains radioiodine impurities.

Folic acid is a member of the vitamin B group which is reduced in the body to tetrahydrofolate, a co-enzyme active in several metabolic processes and produces a haemopoietic response in nutritional megaloblastic anaemias. Folic acid is rapidly absorbed and widely distributed in body tissues.

Hydroxocobalamin is used in the treatment and prevention of Vitamin B12 deficiency. For adults, the daily requirement of Vitamin B12 is probably about 1 to 2 micrograms and this amount is present in most normal diets. However, Vitamin B12 only occurs in animal products, not in vegetables, and therefore strict vegetarian or vegan diets that exclude dairy products may provide an inadequate amount, although a deficiency may not be apparent for many years.
