Mecobalamin is widely used in the treatment of vitamin B12 deficiency, particularly in cases where nerve damage is involved. It is effective in managing peripheral neuropathy, diabetic neuropathy, and other neurological disorders by promoting nerve repair and regeneration. Additionally, it is utilized in the treatment of megaloblastic anemia, as it aids in the synthesis of red blood cells. Mecobalamin is also employed in improving symptoms of fatigue and weakness associated with B12 deficiency. In some cases, it is used as an adjunct therapy in conditions like amyotrophic lateral sclerosis (ALS) to support nerve function. Its role in maintaining healthy nerve cells and improving overall neurological health makes it a valuable component in various therapeutic applications.
