Vitamin B12 + Elemental Iron + Folic Acid
Vitamin B12 + Elemental Iron + Folic Acid Uses, Dosage, Side Effects, Food Interaction and all others data.
Vitamin B12 (cyanocobalamin): Required for the maintenance of normal erthropoiesis, nucleprotein and myelin synthesis, cell reproduction and normal growth; Coenzyme; metabolic functions include protein synthesis and carbohydrate metabolism. Plays role in cell replication and hematopoiesis.
Iron: Essential component in the formation of hemoglobin; adequate amounts of iron are necessary for effective erythropoiesis; also serves as a cofactor of several essential enzymes, including cytochromes that are involved in electron transport. Replacement of iron stores found in hemoglobin, myoglobin, and enzymes; works to transport oxygen via hemoglobin.
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.

Uses
This is used for the prevention and treatment of Iron, vitamin B12 and Folic acid deficiency. Also used for the prevention of Iron deficiency during pregnancy and lactation and as prophylactic therapy of Iron deficiency to cover the recommended daily dietary allowance.
Vitamin B12 + Elemental Iron + Folic Acid is also used to associated treatment for these conditions: Anaemia folate deficiency, Folate deficiency, Iron Deficiency (ID), Iron Deficiency Anemia (IDA), Latent Iron Deficiency, Neural Tube Defects (NTDs), Vitamin Deficiency, Methotrexate toxicity, Nutritional supplementation
How Vitamin B12 + Elemental Iron + Folic Acid works
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.
Dosage
Vitamin B12 + Elemental Iron + Folic Acid dosage
Adult: 1-2 capsules daily; as recommended by the physician.
Children: 1 capsule daily; as recommended by the physician.
Infant: As recommended by the physician.
May be taken with or without food.
Side Effects
Generally well tolerated. In individual cases, a few side-effects occur to oral Iron preparation, such as nausea, vomiting, constipation or diarrhoea.
Toxicity
IPR-MUS LD50 85 mg/kg,IVN-GPG LD50 120 mg/kg, IVN-MUS LD50 239 mg/kg, IVN-RAT LD50 500 mg/kg, IVN-RBT LD50 410 mg/kg
Precaution
Caution should be applied where there is a risk of Iron overload, e.g. Haemochromatosis, Thalassaemia, Haemosiderosis or Haemolytic anaemia.
Interaction
Generally no interactions have been observed. Iron may decrease the absorption of antacids, tetracycline, quinolone antibiotics, levodopa, levothyroxine, methyldopa and pencillamine. Folic acid interacts with antiepileptic drugs, no plasma concentrations of Phenobarbital, phenytoin possibly reduced.
Volume of Distribution
Tetrahydrofolic acid derivatives are distributed to all body tissues but are stored primarily in the liver.
Elimination Route
Folic acid is absorbed rapidly from the small intestine, primarily from the proximal portion. Naturally occurring conjugated folates are reduced enzymatically to folic acid in the gastrointestinal tract prior to absorption. Folic acid appears in the plasma approximately 15 to 30 minutes after an oral dose; peak levels are generally reached within 1 hour.
Elimination Route
After a single oral dose of 100 mcg of folic acid in a limited number of normal adults, only a trace amount of the drug appeared in the urine. An oral dose of 5 mg in 1 study and a dose of 40 mcg/kg of body weight in another study resulted in approximately 50% of the dose appearing in the urine. After a single oral dose of 15 mg, up to 90% of the dose was recovered in the urine. A majority of the metabolic products appeared in the urine after 6 hours; excretion was generally complete within 24 hours. Small amounts of orally administered folic acid have also been recovered in the feces. Folic acid is also excreted in the milk of lactating mothers.
Pregnancy & Breastfeeding use
This preparation can be used in pregnancy and lactation.
Contraindication
Contraindicated in patients with known hypersensivity to any of its ingredients.
Acute Overdose
Initially epigastric pain, diarrhea and vomiting can occur of overdose. Metabolic acidosis, convulsions and coma can occur after recovery. In case of overdose an emetic should be given followed by gastric lavage and general supportive measures.
Storage Condition
Store in cool and dry place. Protect from light.
