Precautions
Folic acid when administered as a single agent in doses above 0.1 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurological manifestations remain progressive. Unmetabolized Folic Acid has the potential to reduce natural killer cells' cytotoxicity, which may result in an impaired immune response.
Pregnancy-Lactation
Interactions
Folic acid: Antiepileptics, oral contraceptives, anti-TB drugs, alcohol, aminopterin, methotrexate, pyrimethamine, trimethoprim and sulphonamides may result to decrease in serum folate contrations. Decreases serum phenytoin concentrations.

Mild transient diarrhea, polycythemia vera, itching, transitory exanthema, and the feeling of swelling of the entire body has been associated with cyanocobalamin.
Mechanism of Action
Folic acid: Required for nucleoprotein synthesis and the maintenance of normal erythropoiesis; folic acid is converted in the liver and plasma to its metabolically active form, tetrahydrofolic acid, by dihydrofolate reductase; prevents neural tube defects in women of childbearing potential and higher doses required during pregnancy.
Vitamin B: Plays a role in the synthesis and maintenance of coenzyme A. Necessary for lipid metabolism, carbohydrate metabolism, tissue respiration, glycogenolysis, inhibition of very low-density lipoprotein (VLDL) synthesis. May increaase chylomicron triglyceride removal from plasma. Vitamin B12 (cyanocobalamin): Required for the maintenance of normal erthropoiesis, nucleprotein and myelin synthesis, cell reproduction and normal growth; intrinsic factor, a glycoprotein secreted by the gastric mucosa, is required for active absorption of Vitamin B12 from the GI tract. Necessary for normal tissue respiration; plays a role in activation of pyridoxine and conversion of tryptophan to niacin.
