Cyanocobalamin is a synthetic form of vitamin B
12
. Vitamin B
12
is the "generic descriptor" name for any vitamers of vitamin B
12
. Because humans and animals can convert cyanocobalamin to any one of the active vitamin B
12
compounds, by definition this makes cyanocobalamin itself a form (or vitamer) of B
12
.

Cyanocobalamin is usually prescribed after surgical removal of part or all of the stomach or intestine to ensure adequate serum levels of vitamin B
12
. It is also used to treat pernicious anemia, vitamin B
12
deficiency (due to low intake from food), thyrotoxicosis, hemorrhage, malignancy, liver disease and kidney disease. Cyanocobalamin injections are often prescribed to gastric bypass patients who have had part of their small intestine bypassed, making it difficult for B
12
to be acquired via food or vitamins. Cyanocobamide is also used to perform the Schilling test to check ability to absorb vitamin B
12
.
