Why is this medication prescribed?
Folic acid is used to treat or prevent folic acid deficiency. It is a B-complex vitamin needed by the body to manufacture red blood cells. A deficiency of this vitamin causes certain types of anemia (low red blood cell count).
How should this medicine be used?
Folic acid comes in tablets. It usually is taken once a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take folic acid exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you are taking folic acid to treat a deficiency, you probably will feel better quickly, often within 24 hours. However, do not stop taking this drug until your doctor tells you to do so.
Other uses for this medicine
