Vitamin B complex + Vitamin C + Folic Acid
Indications
Vitamin B complex + Vitamin C + Folic Acid is used for:
Supplement in order to meet the daily requirements of the water-soluble vitamins in infants, adults and children.
Adult Dose
Adults:
Oral
1-2 Capsule daily.
Child Dose
Renal Dose
Administration
For maximum absorption take on empty stomach, but may take with or after meals to minimize GI irritation
Contra Indications
Hypersensitivity to any of the ingredients of the preparation.
Precautions
Folic acid may mask the symptoms of pernicious anemia in that hematologic remission may occur while neurologic manifestations remain progressive. Administering folic acid may obscure pernicious anemia. Recommended doses are insufficient to correct severe vitamin deficiency states and may be insufficient in patients with markedly increased vitamin requirements.
Daily vitamin requirements must be calculated to avoid over dosage and toxic effects, particularly in pediatric patients.
Pregnancy-Lactation
Interactions
Decreased GI tract absorption with neomycin, aminosalicylic acid, H2-blockers and colchicine. Reduced serum concentrations with oral contraceptives. Reduced effects in anaemia with parenteral chloramphenicol.
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.
Vit C: Deferroxamine, hormonal contraceptives, flufenazine, warfarin, elemental iron, salicylates, warfarin, fluphenazine, disulfiram, mexiletine, vitamin B12.
Adverse Effects
Side effects of Vitamin B complex + Vitamin C + Folic Acid :
Allergic sensitization has been reported following oral administration. May cause nausea, vomiting, constipation or diarrhoea.
Mechanism of Action
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.
Vitamin C is necessary for collagen formation and tissue repair; plays a role in oxidation/reduction reactions as well as other metabolic pathways including synthesis of catecholamines, carnitine, and steroids; also plays a role in conversion of folic acid to folinic acid.
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.
