Gabapentin + Methylcobalamin is a combination of two medicines: Gabapentin and Methylcobalamin. Gabapentin is an alpha 2 delta ligand which decreases pain by modulating calcium channel activity of the nerve cells. Methylcobalamin is a form of vitamin B which helps in the production of myelin, a substance that protects nerve fibers and rejuvenates damaged nerve cells. Together, they relieve neuropathic pain (pain from damaged nerves).
