Vitamin B12 (Cyanocobalamin)


sdz-Vitamin B12 (Cyanocobalamin) - 1000mcg/mL (Generic)
SKU: DP-10065 Category:


The vitamin B12 cyanocobalamin can be used to treat low levels (deficiency) of the vitamin. The B12 vitamin is essential for your body’s ability to use fat and carbohydrates for energy and make new proteins. In addition, it plays a crucial role in the function of cells, blood, and nerves. The majority of people get enough vitamin B12 in their diet, but some health conditions can cause a deficiency (such as poor nutrition, stomach and intestinal problems, infection, cancer). Anemia, stomach issues, and nerve damage are all possible symptoms of severe vitamin B12 deficiency.

A cobalt-containing vitamin, vitamin B12 is synthesized by microorganisms as part of the B complex vitamin family. The most commonly used forms of vitamin B12 are cyanocobalamin and hydroxocobalamin. Vitamin B12 activity is equivalent between them. A source of exogenous vitamin B12 is required in humans for the synthesis of nucleoproteins, myelin, normal growth, and normal erythropoiesis.

To determine whether a patient is sensitive to cobalamins, a test dose should be administered intradermally prior to vitamin B12 administration. For originally diagnosed and relapsed pernicious anemia with severe neurologic manifestations, cyanocobalamin must be administered intravenously. Also in treatment of megaloblastic anemia associated with sprue, supplementation with folic acid is usually necessary and parenteral vitamin B12 may be required. When folic acid is used as the sole hematopoietic agent, permanent degenerative spinal cord lesions can occur when vitamin B12 deficiency is allowed to persist for more than 3 months.

When vitamin B12 is administered to patients with early Leber’s disease (hereditary optic nerve atrophy), they suffer severe and swift optic nerve atrophy. As a result of the increased erythrocyte potassium requirements when converting megaloblastic anemia to normal erythropoiesis with vitamin B12, fatal hypokalemia can occur when serum potassium concentrations are monitored during early vitamin B12 therapy. There are several factors that can impair the therapeutic response to vitamin B12, including concurrent infection, uremia, concomitant treatment with chloramphenicol, and misdiagnosis. It is not recommended to administer cyanocobalamin or hydroxocobalamin intravenously (IV). Pernicious anemia can be misdiagnosed if vitamin B12 is administered indiscriminately. It is rare to have a dietary deficiency of only vitamin B12. Any dietary deficiency will result in multiple vitamin deficiencies.

Side Effects

There may be some discomfort/redness at the injection site, mild diarrhea, itching, or a feeling of swelling all over the body. Tell your doctor or pharmacist if any of these effects persist or worsen.

You have been prescribed this medication because your doctor has determined that the benefits outweigh the risks. There are few serious side effects associated with this medication.

It is possible that this medication will cause low potassium levels in the blood (hypokalemia). If you experience any of these serious side effects: muscle cramps, weakness, irregular heartbeat, call your doctor right away.

It is rare for people who have a rare blood disorder (polycythemia vera) to experience symptoms related to this disorder while taking cyanocobalamin. Immediately seek medical attention if any of the following symptoms occur: chest pain (especially with shortness of breath), weakness on one side of the body, sudden changes in vision, difficulty speaking or breathing.

It is very important to seek medical attention immediately if you experience any very serious side effects, such as: signs of heart failure (such as shortness of breath, swelling ankles/feet, unusual tiredness, unusual/sudden weight gain).

Drug Interactions

In most cases, antibiotics, methotrexate and pyrimethamine invalidate the results of diagnostic microbiological blood tests for folic acid and vitamin B12. It has been shown that chloramphenicol may antagonize the hematopoietic response to vitamin B12. In such cases, it is important to monitor the patient’s hematopoietic response. Colchicine, aminoglycosides, some anticonvulsants (e.g. phenytoin, phenobarbital, primidone), para-aminosalicylic acid, or excessive alcohol consumption for a period longer than two weeks may impair the absorption of vitamin B12. There is a possibility that vitamin C may destroy vitamin B12. It is important for patients not to consume large quantities of vitamin C within an hour after ingesting an oral dose of vitamin B12.

Missed Dose

In order for this medication to be effective, it is very important to take each dose as scheduled. It is very important that you consult your doctor or pharmacist as soon as possible if you miss a dose and ask for a new dosing schedule. It is not advisable to double the dose in order to catch up.


It is very unlikely that you will overdose on this medication. In the event that someone has overdosed and is experiencing serious symptoms such as passing out or having difficulty breathing, they should call 911 at once. In any other case, you should call a poison control center as soon as possible. If you live in the United States, you can contact your local poison control center by dialing 1-800-222-1222.


The presence of benzyl alcohol in some products has been associated with neonatal toxicity in some cases. It appears that the toxic effects were caused by the administration of large amounts of benzyl alcohol (100 to 400 mg/kg/day) to the animals. Neonates should be cautious when using products containing benzyl alcohol, especially if they are receiving other benzyl alcohol-containing medications at the same time.


The consumption of normal daily requirements during pregnancy has not been reported to be associated with any adverse effects. In nursing mothers, vitamin B12 levels are distributed into their milk in concentrations that are similar to the levels in their blood when they are nursing. During lactation, normal daily requirements of calcium and phosphorus have been consumed without any adverse effects reported.


The product should be stored at a temperature of 15-30┬░C. Make sure that the container is protected from light.
