This is a type of vitamin B that is important for making new cells in the body. It is used to prevent and treat certain types of anemia and is crucial for pregnant women to prevent birth defects. It is safe and recommended during pregnancy and breastfeeding.

Indications

Folic acid is indicated for the treatment of-
  • Folic acid deficiency
  • Megaloblastic anemia
  • Anemias of nutritional origins, pregnancy, infancy, or childhood.

Pharmacology

Folic acid, as it is biochemically inactive, is converted to tetrahydrofolic acid and methyltetrahydrofolate by dihydrofolate reductase (DHFR). These folic acid congeners are transported across cells by receptor-mediated endocytosis where they are needed to maintain normal erythropoiesis, synthesize purine and thymidylate nucleic acids, interconvert amino acids, methylate tRNA, and generate and use formate. Using vitamin B12 as a cofactor, folic acid can normalize high homocysteine levels by remethylation of homocysteine to methionine via methionine synthetase.

Precautions & Warnings

It should be used with caution in patients who may have folate dependent tumours. It should never be given alone or in conjunction with inadequate amounts of vitamin B12 for the treatment of undiagnosed megaloblastic anaemia. Although folic acid may produce a haematopoietic response in patients with a megaloblastic anaemia due to vitamin B12 deficiency it should not be given alone in vitamin B12 deficiency states as it may precipitate the onset of subacute combined degeneration of the cord. In elderly people a cobalamin absorption test should be done before long term folate. No harmful results found from short courses of folate.

Storage Conditions
