Precautions

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/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.

Doses of cyanocobalamin exceeding 10 mcg daily may produce hematologic response in patients with folate deficiency. In discriminate administration may mask the true diagnosis.

Adverse Reactions

Anaphylactic shock and death have been reported with administration of parenteral Vitamin B12.

Pregnancy and lactation

Pregnancy Category C

Vitamin B12 is known to be excreted in human milk. Amounts of Vitamin B12 that are recommended by the Food and Nutrition Board, National Academy of Science-National Research Council for lactating women (4 mcg daily) should be consumed during lactation.

Renal and liver Impairment

Cellular uptake of vitamin B12 in patients with chronic renal failure. This could cause a paradoxical increase in cellular homocysteine levels even with normal total B12 levels, resulting in a functional B12 deficiency.
