Cyanocobalamin Injection

Product Overview

Cyanocobalamin Injection is a prescription injectable formulation of Vitamin B12, an essential water-soluble vitamin required for red blood cell formation, neurologic function, and DNA synthesis. Cyanocobalamin is a synthetic form of Vitamin B12 commonly used for the treatment and prevention of vitamin B12 deficiency, particularly in patients who have impaired absorption or require rapid replenishment.

Vitamin B12 deficiency may arise due to conditions such as pernicious anemia, gastrointestinal disorders, bariatric surgery, chronic alcoholism, malabsorption syndromes, or prolonged use of certain medications. Untreated deficiency can lead to anemia, neuropathy, cognitive disturbances, and fatigue.

The injectable route provides direct systemic absorption, bypassing gastrointestinal limitations, and is often preferred when oral or sublingual supplementation is insufficient. Cyanocobalamin Injection is available by prescription only and must be administered under medical supervision.

Dosage & Administration

General Dosing Information

Dosing of Cyanocobalamin Injection is individualized based on the patient’s clinical condition, laboratory results, and therapeutic response. The prescribing healthcare provider determines the appropriate dose, frequency, and duration of therapy.

Therapy may be adjusted based on clinical response and laboratory results.

Mechanism of Action

Cyanocobalamin functions as an active form of Vitamin B12 in the body and plays a critical role in:

• DNA synthesis and cellular replication

• Conversion of homocysteine to methionine

Its injectable form ensures rapid and reliable restoration of vitamin B12 levels.
