Walcobal 2500mcg Injection WALCOBAL 2500 contains Methylcobalamin, an active coenzyme form of Vitamin B12 essential for neuronal maintenance and hematopoiesis. Methylcobalamin functions as a donor of methyl groups and facilitates the transmethylation reaction in the synthesis of methionine from homocysteine. It promotes myelin sheath synthesis, enhances axonal nerve regeneration, and stimulates erythroblast maturation and nucleic acid synthesis. WALCOBAL 2500 is indicated for the treatment of peripheral neuropathy, diabetic neuropathy, megaloblastic anemia due to Vitamin B12 deficiency, and severe neurological manifestations of cobalamin deficiency.
