Why this medication is 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 this medication should 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
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Special precautions
Before taking folic acid:
- tell your doctor and pharmacist if you are allergic to folic acid or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially phenytoin (Dilantin) and vitamins.
Special dietary instructions
Your doctor may tell you to eat more liver, foods prepared from dried yeast, fruit, and fresh leafy green vegetables to increase the folic acid in your diet.
What to do if you forget a dose
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
