Vitamin B12 injection ampules, specifically containing Cyanocobalamin, are a synthetic form of vitamin B12 that is used to address low levels or deficiency of this essential vitamin. 

Vitamin B12 plays a crucial role in various bodily functions, including the utilization of fat and carbohydrates for energy production and the synthesis of new proteins. It is also necessary for maintaining healthy blood, cells, and nerves within the body.

  • Administer the injection as directed by your healthcare provider, either intramuscularly (into a muscle) or subcutaneously (under the skin).
