Uses of Methylcobalamin Injection

Methylcobalamin is an artificially composed Vitamin B-12. The medications work by helping in the synthesis of myelin (lipid-rich material that covers nerve fibers) which protects the nerve fibers and thereby provides relief from diabetic & peripheral neuropathy, sciatica pain, and back pain in affected individuals. It also promotes nucleic acid synthesis in the bone marrow which helps in the maturation and division of erythroblasts thus preventing poor production of red blood cells and thereby improving megaloblastic anemia in affected individuals. Methylcobalamin injection is indicated in the following mentioned disease: 

  • Treats diabetic and peripheral neuropathies
  • Treats megaloblastic anemia (caused by vitamin B12 deficiency)
  • Treats sciatica pain (leg pain), back pain, and general weakness in affected individuals.
