Uses of Rejunex Injection 1Ml
What is it prescribed for?
Peripheral Neuropathy
Peripheral neuropathy is the damage to the peripheral nerves (nerves that are present outside the brain and spinal cord). This nerve damage mostly occurs in your feet and hands resulting in weakness, numbness, and pain. There are several causes that can lead to peripheral neuropathy such as diabetes, injuries, and infections. Rejunex Injection 1Ml is used in the treatment of peripheral neuropathy. The medicine helps in the production of myelin, which covers nerve fibres and protects them.
Megaloblastic Anaemia
Megaloblastic Anaemia is a bone marrow disorder wherein there may be an overproduction of abnormal and immature red blood cells. This condition mainly occurs due to a deficiency of either Vitamin B12 or folic acid in your body. Symptoms may include muscle weakness, diarrhoea, vision problems, etc. Rejunex Injection 1Ml is used to treat anaemia due to deficiency of Vitamin B12. The medicine helps in the production of red blood cells.
