<p>Pyridoxine&nbsp;(vitamin B6) is used to prevent or treat low levels of vitamin B6 in people who do not get enough of the vitamin from their diets. Most people who eat a normal diet do not need extra vitamin B6. However, some conditions (such as alcoholism, liver disease,&nbsp;overactive thyroid,&nbsp;heart failure) or medications&nbsp;(such as isoniazid, cycloserine, hydralazine,&nbsp;penicillamine) can cause low levels of vitamin B6. Vitamin B6 plays an important role in the body. It is needed to maintain the health of nerves,&nbsp;skin, and red&nbsp;blood cells.<br />
