Translations:Cyanocobalamin/9/en

Medical use

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 or inability to absorb due to genetic or other factors), 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. Cyanocobalamin is also used to perform the Schilling test to check ability to absorb vitamin B
₁₂.
