Folic acid is used to treat or prevent certain anemias caused by poor diet, pregnancy, alcoholism, liver disease, certain stomach/intestinal problems, kidney dialysis, or other conditions. This medication helps to relieve symptoms such as unusual tiredness and diarrhea that can occur with these types of anemias. Women of childbearing age should maintain adequate amounts of folic acid either through diet or supplements to prevent spinal cord birth defects.

Folic acid is a B-complex vitamin needed to form healthy cells, especially red blood cells.
