Allergic sensitization has been reported following both oral and parenteral administration of folic acid.

​CLINICAL PHARMACOLOGY Oral iron is absorbed most efficiently when administered between meals. Iron is critical for normal hemogloblin syntheis to maintain oxygen transport, energy production and proper function of cells. Adequate amounts of iron are necessary for effective erythropoiesis. Iron also serves as a cofactor of several essential enzymes, including cytochromes, which are involved in electron transport. Folic acid is required for nucleoprotein synthesis and the maintenance of normal erythropoiesis. Folic acid is the precursor of tetrahydrofolic acid, which is involved as a cofactor for transformylation reactions in the biosynthesis of purines and thymidylates of nucleic acids. Deficiency of folic acid may account for the defective deoxyribonucleic acid (DNA) synthesis that leads to megaloblast formation and megablastic macrocytic anemias. Vitamin B ​12 ​ is essential to growth cell reproduction, hematopoiesis, nucleic acid, and myelin synthesis. Deficiency may result in megaloblastic anemia or pernicious anemia.
