Vitamin B6 plays an important role in the body. It is needed to maintain the health of nerves, skin, and red blood cells.Pyridoxine has been used to prevent or treat a certain nerve disorder (peripheral neuropathy) caused by certain medications (such as isoniazid). It has also been used to treat certain hereditary disorders (such as xanthurenic aciduria, hyperoxaluria, homocystinuria).
