Vitamin B12 Injection Cyanocobalamin 1000 mcg/mL 25/Pack (Rx)

Vitamin B12 Cyanocobalamin Injection 1,000 mcg/mL is used to treat and prevent Vitamin B12 deficiency, which can lead to serious conditions such as pernicious anemia and neurological disorders. It’s especially beneficial for individuals with absorption issues, such as those with gastrointestinal disorders or after certain surgeries. This injection aids in red blood cell formation, neurological function, and DNA synthesis. Administered intramuscularly or subcutaneously, it offers a direct route for replenishing B12 levels, essential for maintaining energy, cognitive function, and overall health.

Vitamin B12 Cyanocobalamin Injection by American Regent is a sterile solution used to treat vitamin B12 deficiency and prevent associated conditions such as pernicious anemia and neurological disorders. Each mL of the solution contains 1,000 mcg of cyanocobalamin. The product is packaged in a 25-pack of vials, making it suitable for both clinical and home settings where regular supplementation of vitamin B12 is necessary.

Details and Features

Active Ingredient: Cyanocobalamin, a synthetic form of vitamin B12.
Concentration: 1,000 mcg/mL.
Packaging: 25 single-dose or multiple-dose vials per pack, depending on specific packaging.
Route of Administration: Intramuscular (IM) or Subcutaneous (SC) injection.
Indications: Used primarily to treat vitamin B12 deficiencies due to malabsorption, dietary inadequacies (e.g., in vegans), or certain medical conditions like pernicious anemia. It is also used to manage vitamin B12 deficiencies resulting from specific surgeries, diseases of the stomach or gut, and any other genetic disorders affecting vitamin B12 metabolism.

Mechanism of Action

Vitamin B12 is essential for normal blood formation, cellular metabolism, and neurological function. Cyanocobalamin acts as a precursor for the bioactive forms of vitamin B12, methylcobalamin, and adenosylcobalamin, which are critical co-factors in DNA synthesis and red blood cell production. It plays a crucial role in the maintenance of the myelin sheath that surrounds nerves, thereby supporting neurological health.

Warnings

• Allergic Reactions: Although rare, hypersensitivity to cyanocobalamin can occur. Immediate medical attention is required if an allergic reaction happens.
  
• Optic Nerve Atrophy: Administering cyanocobalamin to patients with Leber's disease or hereditary optic nerve atrophy should be done cautiously, as it may worsen the condition.
  
• Hypokalemia: Rapid treatment of severe anaemia with vitamin B12 could cause low potassium levels (hypokalemia), necessitating monitoring.
  
• Polycythemia Vera: An increase in red blood cell mass may occur, which needs medical evaluation.

Side Effects

While generally well-tolerated, some patients may experience side effects:

Common Side Effects:

• Pain or redness at the injection site
  
• Mild diarrhea
  
• Itching or rash

Serious Side Effects (seek medical attention):

• Signs of an allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
  
• Peripheral vascular thrombosis: Increased risk of clotting in individuals with elevated levels.

Other Considerations:

• Monitoring: Regular monitoring of vitamin B12 levels, complete blood counts, and neurological function is advisable, especially in long-term use.
  
• Diet and Lifestyle: In conjunction with injections, dietary adjustments or oral supplementation may be considered to maintain adequate vitamin B12 levels, especially in dietary-related deficiencies.

Vitamin B12 Cyanocobalamin Injection remains a critical intervention in managing vitamin B12 deficiencies, allowing for direct absorption and rapid correction. Safe administration under the guidance of a healthcare professional ensures optimal effectiveness along with routine monitoring to preclude potential complications or adverse effects.
