Implications for Patient Care
Cyanocobalamin is used to treat vitamin B12 deficiency, including pernicious anemia.3
Cyanocobalamin nasal spray is not labeled for initial treatment or patients with vitamin B12 deficiency that includes nervous system involvement.4 When switching patients from cyanocobalamin injection to the nasal formulation, ensure patients understand differences in dosing as well as how to administer.
Alternative Agents & Management
- Consider reserving supplies of cyanocobalamin injection for patients who require initial treatment, or patients who have nervous system involvement.
- Cyanocobalamin nasal spray (Nascobal®) may be an appropriate alternative for patients who have successfully received treatment with cyanocobalamin injection and have no nervous system symptoms. The dose of cyanocobalamin nasal spray is one spray in one nostril once weekly. Ensure patients understand priming requirements.4
