Vitamin B12 deficiency may cause anemia and permanent nerve damage. Individuals may suffer from a lack of vitamin B12 for a variety of reasons, including certain diseases, infections, medications or a vegan diet, says MedlinePlus. Cyanocobalamin injections are greatly beneficial for individuals who have trouble absorbing vitamin B12 from the intestine, as the injection method ensures that the vitamin goes directly into the bloodstream.

Patients requiring cyanocobalamin injections usually receive them daily for the first week of treatment. As their condition stabilizes, the need for injections becomes less frequent. Eventually, they may only receive the injections once a month for preventive purposes, states MedlinePlus. Individuals who are chronically deficient in vitamin B12 have to receive cyanocobalamin injections for the rest of their lives.

Prior to and during the course of cyanocobalamin injections, patients should always keep their doctor up to date about any medicines or dietary supplements that they are taking, advises MedlinePlus. They should inform their doctor about allergies or alcohol consumption habits, and let the doctor know if they have ever had kidney disease or Leber's hereditary optic neuropathy. Individuals should also notify their doctor if they are pregnant, planning to conceive or breast-feeding.
