Cyanocobalamin is a synthetic form of vitamin B12. It is prescribed as a liquid, oral tablet, or injection for individuals with low vitamin B12. Patients with cancer, malnutrition, or pernicious anemia are at an increased risk of vitamin B12 deficiencies. Patients with cobalt allergies or Leber's disease should not have vitamin B12 injections. Patients should let their doctor know about any history of heart disease, gout, diabetes, bleeding disorders, iron deficiencies, or ulcerative colitis if they are considering this medication. This is to ensure it is safe for them to take.

Potential side effects of vitamin B12 supplements or injections include diarrhea, nausea, joint pain, headaches, dizziness, itching, and upset stomach. When cyanocobalamin is given by injection, patients could notice injection site pain, redness, or swelling. This medicine can cause a fever and a feeling of swelling that spreads over the entire body. Patients will be closely monitored during treatment. They should let their doctor know if they experience any side effects.
