INTRODUCTION

T METHYL OD contains Methylcobalamin which is an Anti-anemic agent. It is used in the treatment of peripheral neuropathies and megaloblastic anemia caused by vitamin B12 deficiency. Peripheral neuropathy can be defined as a nerve pain that arises due to damage of peripheral nerves (nerves outside the brain and spinal cord) by traumatic injuries, infections or by metabolic problems like diabetes. It is characterized by stabbing, burning or tingling sensation, usually, in the hands and feet. Megaloblastic anemia can be defined as a decrease in number of red blood cells due to acquired deficiency of vitamin B12 or folic acid.

Vitamin B12 is essential for the proper functioning of brain and nerves and for the production of red blood cells. Methylcobalamin is a form of vitamin B12 that helps in the synthesis of various essential amino acids required for cellular replication, production of red blood cells and myelin formation (a protective layer covering the nerve fiber).

The most common side effects of taking this medicine are headache, loss of appetite, nausea, vomiting and diarrhea. T METHYL OD can be taken with or without food. Do not stop taking this medicine without your doctor’s advice. Continue to take this medicine, as long as your doctor tells you to do so, to obtain better results. Before taking T METHYL OD, inform your doctor if you are pregnant or nursing mother.

USES OF T METHYL OD

Used to treat:

• Peripheral neuropathy (nerve pain)
• Megaloblastic anemia caused by vitamin B12 deficiency

HOW T METHYL OD WORKS

T METHYL OD promotes the synthesis of nucleic acid and various proteins involved in the production of red blood cells. It also enhances cell repair and replication and helps in the formation of myelin sheath (a protective covering of the nerve fibers), thereby reducing pain.
