How RENERVE G 300MG CAPSULE Works
RENERVE G 300MG CAPSULE contains Gabapentin and Methylcobalamin. Gabapentin reduces pain sensation by interfering with the pain signals travelling between the damaged nerves and the brain. Methylcobalamin repairs and rejuvenates the damaged nerve cells. It improves the production of a substance called myelin which forms a protective covering around the nerve fibres. This protects the nerve cells from getting damaged further. Collectively, this medicine effectively reduces nerve pain and protects the nerve cells from further damage.
