What it's used for
Folic acid is used to treat megaloblastic anemias due to folic acid deficiency, as well as anemias of nutritional origin, pregnancy, infancy, or childhood.
Source: U.S. FDA-approved prescribing information (openFDA).
Typical dosing
Oral administration is preferred, as patients with malabsorption are generally able to absorb folic acid given by mouth.
Dosing shown here is the general FDA-labeled range. Your prescribing clinician determines the exact dose, form, and schedule for you — this is not a substitute for medical advice.
Boxed warning / key safety info
Administering folic acid alone is improper therapy for pernicious anemia and other megaloblastic anemias involving a vitamin B12 deficiency.
Common side effects
Allergic sensitization has been reported following both oral and parenteral administration, though the drug is relatively nontoxic.

Folic Acid cost without insurance
Cash prices for Folic Acid without insurance vary widely by pharmacy, strength and quantity — the same prescription can cost very different amounts at two pharmacies in the same town. That is the problem a membership solves.
Folic Acid is on Tab's covered $0 generic list.

Folic Acid side effects
Folic Acid: Allergic sensitizations have been reported following both oral and parenteral administration of folic acid. Ferrous Fumarate: Gastrointestinal disturbances (anorexia, nausea, diarrhea, constipation, heartburn and vomiting) occur occasionally, but are usually mild and may subside with continuation of therapy. Reducing the dose and administering it with meals will minimize these effects in the sensitive patient. Increasing fiber in the diet can relieve constipation. Iron may turn stools black. This is a harmless effect that is a result of unabsorbed iron. Although the absorption of iron is best when taken between meals, giving Integra FTM after meals may control occasional G.I. disturbances. Integra FTM is best absorbed when taken at bedtime.

Who should not take folic acid
Integra FTM is contraindicated in patients with known hypersensitivity to any of its ingredients; also, all iron compounds are contraindicated in patients with hemosiderosis, hemochromatosis, or hemolytic anemias. Pernicious anemia is a contraindication, as folic acid may obscure its signs and symptoms.
