What is Vitamin B12 (Cyanocobalamin)?

Vitamin B12, also known as cyanocobalamin, is a synthetic form of an essential nutrient used to treat deficiencies.

Vitamin B12 is FDA-approved for the following conditions:

  • Pernicious anemia (autoimmune condition, that lowers the absorption of vitamin B12 from food)
  • Atrophic gastritis (inflammation and thinning of the stomach lining)
  • Gastrectomy (total or partial)
  • Malabsorption
  • Helicobacter pylori infection (major cause of stomach ulcers)
  • Diphyllobothrium latum infection
  • Small bowel bacterial overgrowth
  • Chronic acid-reducing medication use
  • Long-term metformin use
  • Pancreatic insufficiency
  • Malignancy of the pancreas or bowel
  • Dietary deficiency of vitamin B12
  • Transcobalamin II deficiency (a rare genetic condition usually occurring in infancy)

Besides the FDA-approved conditions, vitamin B12 is also used for “off-label” purposes, meaning it is prescribed for conditions not officially approved by the FDA. These include:

  • Cyanide poisoning
  • Smoke inhalation
  • Surgery-associated vasoplegia (involves low blood pressure and weak blood vessels despite good heart function)
  • Vasodilatory shock (when blood vessels widen, causing less blood to reach organs like the brain and heart)
  • Folic acid deficiency
  • Potential reversible cognitive impairment and dementia
  • Nitrous oxide myelopathy

How Does Vitamin B12 Work?

Vitamin B12 helps our bodies make DNA and produce energy, especially in the cells that create red blood cells. When we take synthetic vitamin B12, either as a pill or injection, our small intestine absorbs it after it binds to certain proteins.

If we get it through injection, it goes directly into our bloodstream. In the blood, it attaches to plasma proteins and is then picked up by specific B12-carrying proteins like transcobalamin I and II, which transport it into our cells. Most of the vitamin is stored in the liver for future use.

Dosage Information and Usage

Dosage Form and Strengths of Vitamin B12

Vitamin B12 comes in 1,000 mcg/mL injectable solution.

Usage

Depending on the patient’s condition, vitamin B12 can be given through muscle (IM) or skin (SC) injections. For serious deficiencies or absorption issues, injections are often necessary.

Typically, the dosage is 100 mcg of cyanocobalamin daily for a week, then weekly for a month, and finally monthly for life. Before starting, a small test dose under the skin may be given to check for allergic reactions.

It’s important not to inject it into a vein, as this can be dangerous. In severe cases, a large dose through a vein might be used, but only under a doctor’s supervision.

Side Effects of Vitamin B12

Common Side Effects

  • Shortness of breath
  • Swelling
  • Rapid weight gain
  • Hypokalemia (leg cramps, irregular heartbeats, tingling/numbness, muscle weakness, or limp feeling)
  • Numbness or tingling and joint pain
  • Fever
  • Swollen tongue
  • Itching or rash

Serious but Rare Side Effects

  • Allergic reactions like itching
  • Acne, rosacea
  • Anaphylaxis
  • Cobalt sensitivity-related allergic reactions
  • Pulmonary edema (too much fluid build up in the lungs)
  • Congestive heart failure
  • Peripheral vascular thrombosis (inflammation in the arteries)

Warnings and Precautions

  • Patients with early Leber’s disease who took cyanocobalamin had severe optic atrophy quickly. This means that cyanocobalamin could worsen optic nerve problems.
  • Severe megaloblastic anemia treatment may lead to low potassium levels and sudden death. Intense treatment for severe anemia with cyanocobalamin could cause dangerous electrolyte imbalances and heart rhythm problems.
  • Anaphylactic shock and death have happened after getting cyanocobalamin injections. A small skin test is suggested before using it.
  • Benzyl Alcohol in this product can cause a deadly syndrome in premature babies.
  • Aluminum in this product might be harmful, especially if the kidneys don’t work well. Premature babies are at higher risk because their kidneys are still developing.
  • Blood tests should be done before and during vitamin B12 treatment to check for certain conditions and see how well the treatment is working.
  • Some medications can affect vitamin B12 blood tests or how the body absorbs vitamin B12.
  • Long-term use of some medications or heavy alcohol intake could make it hard for the body to absorb vitamin B12.
  • Vitamin B12 hasn’t been proven to cause cancer, but pernicious anemia might increase the risk of stomach cancer.
  • Children should only take the recommended amount of vitamin B12.

Overdosage

Taking excessive vitamin B12 isn’t typically concerning as the body eliminates the excess through bile and urine. Overdosing on vitamin B12, even with high doses, is uncommon, and there’s no specific treatment if it occurs.

FREQUENTLY ASKED QUESTIONS

Certain drugs can affect how well your body absorbs Vitamin B12. Aminosalicylic acid, used for digestive problems, and colchicine, an anti-inflammatory for gout, might reduce B12 absorption. Metformin, a diabetes drug, and proton pump inhibitors like omeprazole (Prilosec) and lansoprazole (Prevacid), which reduce stomach acid, can also decrease B12 absorption. Additionally, taking Vitamin C (ascorbic acid) supplements with B12 can reduce the amount of B12 available in your body. To avoid this interaction, take Vitamin C two or more hours after taking a B12 supplement. Your doctor may suggest changing your medication or adjusting the timing of your doses to offset these potential interactions.

No, vitamin B12 injections do not need to be refrigerated. They should be stored at room temperature in a safe place away from children and pets. Make sure to store any unused equipment and medication securely.

No, vitamin B12 cannot cause cyanide poisoning. The cyanide in vitamin B12 is bound in a way that makes it harmless. Even large amounts of vitamin B12 from injections are not likely to harm your health.

Vitamin B12 injections can sometimes cause pain or redness at the injection site, mild diarrhea, itching, or a feeling of swelling all over the body. If these effects last or get worse, you should tell your doctor. Injecting in the wrong area can cause an abscess (a painful collection of pus) to form under the skin, so it’s important to only inject where your nurse or doctor recommends. Do not inject into an area that is already painful or inflamed. If you do, seek medical advice right away.

No, cyanocobalamin (Vitamin B12) injections are prescription medications. They require a prescription after a doctor has diagnosed you with low levels of vitamin B12.

The daily requirement of Vitamin B12 is 2.4 micrograms (mcg). This amount is recommended to meet the needs of almost all healthy individuals. Once again, the daily intake depends on factors like age and sex, and these recommendations help ensure that people get enough Vitamin B12 to stay healthy.

Research suggests that cyanocobalamin may be absorbed more efficiently by the body, while methylcobalamin tends to have a higher retention rate. However, studies also indicate that the absorption and retention differences between the two forms are minimal.

Typically, cyanocobalamin injections are administered once daily during the initial 6-7 days of treatment. After that, as your red blood cell count begins to normalize, your healthcare provider may adjust the frequency to every other day for approximately 2 weeks. Following this phase, you might receive the injection every 3-4 days for another 2-3 weeks to maintain adequate Vitamin B12 levels. This gradual adjustment in dosing helps ensure effective treatment and restoration of Vitamin B12 levels in your body.

Injecting Vitamin B12 into a nerve is not a standard practice and can potentially cause adverse effects. Normally, Vitamin B12 injections are administered into the muscle, not directly into a nerve. If mistakenly injected into a nerve, it can lead to discomfort, tingling sensations, or even damage to the nerve.

Yes, you can administer B12 shots at home once you have been trained by your healthcare provider. Initially, the treatment involves daily intramuscular injections of vitamin B12. This method allows for convenience and flexibility, as patients can self-administer the injections in the comfort of their homes.
