Important Safety Information


Sensitivity to cobalt and/or vitamin B12 is a contraindication.


Patients with early Leber's disease (hereditary optic nerve atrophy) who were treated with cyanocobalamin suffered severe and swift optic atrophy.

Hypokalemia and sudden death may occur in severe megaloblastic anemia which is treated intensely.

Anaphylactic shock and death have been reported.

This product contains Benzyl Alcohol. Benzyl Alcohol has been reported to be associated with a fatal "Gasping Syndrome" in premature infants.

This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired.

Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.


Vitamin B12 deficiency that is allowed to progress for longer than 3 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.

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

Drug Interactions:

Persons taking most antibiotics, methotrexate and pyrimethamine invalidate folic acid and vitamin B12 diagnostic blood assays.

Colchicine para-aminosalicylic acid and heavy alcohol intake for longer than 2 weeks may produce malabsorption of vitamin B12.

Information for Patients:

Patients with pernicious anemia should be informed that they will require monthly injections of vitamin B12 for the remainder of their lives. Failure to do so will result in return of the anemia and in development of incapacitating and irreversible damage to the nerves of the spinal cord. Also, patients should be warned about the danger of taking folic acid in place of vitamin B12, because the former may prevent anemia but allow progression of subacute combined degeneration.

A vegetarian diet which contains no animal products (including milk products or eggs) does not supply any vitamin B12. Patients following such a diet, should be advised to take oral vitamin B12 regularly. The need for vitamin B12 is increased by pregnancy and lactation. Deficiency has been recognized in infants of vegetarian mothers who were breast fed, even though the mothers had no symptoms of deficiency at the time.

Laboratory Tests:

During the initial treatment of patients with pernicious anemia, serum potassium must be observed closely the first 48 hours and potassium replaced if necessary.

Hematocrit, reticulocyte count, vitamin B12, folate and iron levels should be obtained prior to treatment. Hematocrit and reticulocyte counts should be repeated daily from the fifth to seventh days of therapy and then frequently until the hematocrit is normal. If folate levels are low, folic acid should also be administered. If reticulocytes have not increased after treatment or if reticulocyte counts do not continue at least twice normal as long as the hematocrit is less than 35%, diagnosis or treatment should be reevaluated. Repeat determinations of iron and folic acid may reveal a complicating illness that might inhibit the response of the marrow.


Patients with pernicious anemia have about 3 times the incidence of carcinoma of the stomach as the general population, so appropriate tests for this condition should be carried out when indicated.

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.


  • Teratogenic Effects: Pregnancy Category C
  • Adequate and well-controlled studies have not been done in pregnant women. However, vitamin B12 is an essential vitamin and requirements are increased during pregnancy. Amounts of vitamin B12 that are recommended by the Food and Nutrition Board, National Academy of Science-National Research Council for pregnant women (4 mcg daily) should be consumed during pregnancy.

Nursing Mothers:

  • 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.

Pediatric Use:

  • Intake in children should be in the amount (0.5 to 3 mcg daily) recommended by the Food and Nutrition Board, National Academy of Science-National Research Council.

Vitamin B12

Vitamin B12, or cobalamin, plays several important roles in the body. It's vital for energy production, converting food into usable energy. Additionally, B12 is necessary for the formation of red blood cells, ensuring efficient oxygen transport throughout the body. It plays a key role in maintaining the health of the nervous system, aiding in the production of neurotransmitters and myelin, the protective coating of nerve fibers. B12 is also involved in DNA synthesis, supporting cell division and overall cellular health.

Individuals seeking to boost their energy levels through B12 shots, these injections can indeed be effective. B12 plays a key role in energy production, so supplementing with injections can provide a quick and direct way to increase B12 levels in the body. By bypassing the digestive system, B12 shots allow for rapid absorption into the bloodstream, potentially leading to faster and more noticeable improvements in energy levels compared to oral supplements. However, it's important to note that the effectiveness of B12 shots may vary depending on individual factors such as current B12 levels, overall health status, and underlying causes of fatigue.

Vitamin B12, also known as cobalamin, is indispensable for various physiological functions in the body. It serves as a key player in energy metabolism, aiding in the conversion of carbohydrates into glucose, which the body utilizes for energy. Additionally, B12 is crucial for the formation of red blood cells, ensuring proper oxygen transport to tissues and organs. It plays a pivotal role in maintaining the health of the nervous system by supporting the production of myelin, the protective coating of nerve fibers, and facilitating nerve signal transmission.

B12 is also involved in mood regulation, influencing the synthesis of neurotransmitters like serotonin and dopamine, which play a role in emotional well-being. In essence, vitamin B12 is fundamental for sustaining optimal bodily functions, including energy production, blood cell formation, nervous system health, DNA synthesis, and mood regulation.

Vitamin B12 deficiency occurs when the body lacks an adequate amount of vitamin B12 to maintain optimal health and functioning. This deficiency can arise from various factors, including inadequate dietary intake, impaired absorption, or certain medical conditions. Symptoms of vitamin B12 deficiency can vary widely and may include fatigue, weakness, pale skin, shortness of breath, neurological symptoms such as numbness or tingling in the hands and feet, difficulty walking, memory loss, and mood changes. If left untreated, severe vitamin B12 deficiency can lead to complications such as megaloblastic anemia, nerve damage, and neurological disorders. Treatment typically involves vitamin B12 supplementation, either through oral supplements or injections, depending on the severity of the deficiency and underlying causes.
