DRUG CLASS AND MECHANISM: Cyanocobalamine or vitamin B12 is an essential B-vitamin. Cyanocobalamine is classified as a water-soluble vitamin. Food sources of vitamin B12 include fish, shellfish, meats, and dairy products. Vitamin B12 is necessary for growth, cell reproduction, production of red blood cells (hematopoiesis), and the production of myelin and nucleoprotein. Vitamin B12 also plays an important role in the breakdown or metabolism of fats and carbohydrates and has a role in protein synthesis. Vitamin B12 deficiency may result in anemia, gastrointestinal problems, and nerve damage. Cyanocobalamine is used to treat pernicious anemia and vitamin B12 deficiency. It is also used in the Schilling test to determine vitamin B12 absorption. Cyanocobalamine was approved by the FDA in 1949.
