Ingredients and Safety

Ingredients: The active ingredient in this injection is cyanocobalamin at a concentration of 1000 mcg/mL.

Cautions: Do not take large doses of vitamins without your doctor’s direction and do not stop using this medicine without consulting your doctor. It is important to keep all doctor and laboratory appointments while using this medicine. Check with your doctor or pharmacist before taking any new medications.

Contraindications: This preparation should not be used by individuals who are sensitive to cobalt or vitamin B12. Additionally, it contains benzyl alcohol and should not be used in newborns or individuals who are sensitive to benzyl alcohol.

Warnings: Patients with early Leber's disease (hereditary optic nerve atrophy) may experience severe and rapid optic atrophy when treated with vitamin B12. Additionally, treating severe megaloblastic anemia with vitamin B12 can lead to fatal hypokalemia due to increased erythrocyte potassium requirements.

Considerations: Exceeding daily doses of vitamin B12 beyond 10 mcg may induce a hematologic response in patients with folate deficiency. Uncontrolled use of vitamin B12 could potentially obscure the accurate diagnosis of pernicious anemia. Vitamin B12 deficiency left untreated for more than three months may lead to permanent degenerative spinal cord lesions. Additionally, high doses of folic acid (exceeding 0.1 mg per day) may result in hematologic remission in patients with vitamin B12 deficiency. However, folic acid does not prevent neurological symptoms, and without proper treatment with vitamin B12, irreversible damage may occur.

Additional Information

Doses of vitamin B12 exceeding 10 mcg daily may produce a hematologic response in patients who have a folate deficiency. Indiscriminate administration of vitamin B12 may mask the true diagnosis of pernicious anemia. Vitamin B12 deficiency that is allowed to progress for longer than three months may produce permanent degenerative lesions of the spinal cord. Doses of folic acid greater than 0.1 mg per day may result in hematologic remission in patients with vitamin B12 deficiency. Neurologic manifestations will not be prevented with folic acid, and if not treated with vitamin B12, irreversible damage will result.

Laboratory Tests
Patients with pernicious anemia have a higher incidence of stomach carcinoma, so appropriate tests should be performed when indicated.

Drug Interactions
Malabsorption of vitamin B12 may occur with neomycin, colchicine, para-aminosalicylic acid, or prolonged alcohol intake. Chloramphenicol and other bone marrow suppressant drugs may interfere with the efficacy of vitamin B12.

Drug/Laboratory Test Interactions
Most antibiotics, methotrexate, and pyrimethamine invalidate folic acid and vitamin B12 diagnostic microbiological blood assays.

Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term studies in animals to evaluate carcinogenic potential have not been done. There is no evidence from long-term use in patients with pernicious anemia that cyanocobalamin is carcinogenic. Pernicious anemia is associated with an increased incidence of carcinoma of the stomach, but this is believed to be related to the underlying pathology and not to treatment with cyanocobalamin.

Vitamin B12 is considered compatible during pregnancy. While adequate and well-controlled studies specifically in pregnant women are limited, vitamin B12 is essential, and its requirements increase during pregnancy. Pregnant women are recommended to consume the amount of vitamin B12 as advised by the Food and Nutrition Board, National Academy of Sciences-National Research Council, which is 4 mcg daily.

Nursing Mothers
Vitamin B12 is considered compatible during breastfeeding. It is known to be excreted in human milk. Lactating women are recommended to consume the amount of vitamin B12 as advised by the Food and Nutrition Board, National Academy of Sciences-National Research Council, which is 4 mcg daily. Vitamin B12 levels in the milk of nursing mothers approximate the mother's blood levels of vitamin B12.

Pediatric Use
The safety and effectiveness of this injection in pediatric patients have not been established.

Store at 15-30℃. Protect from light.
