Usage
This combination medication is primarily prescribed for the treatment and prevention of iron-deficiency anemia, a condition characterized by insufficient red blood cells due to low iron levels. It also addresses deficiencies in folic acid and vitamin B12, which are crucial for red blood cell formation and nerve function. It can be used during pregnancy and breastfeeding to prevent deficiencies and for those with nutritional malabsorption issues. This combination falls under the pharmacological classification of hematinics and nutritional supplements.
The mechanism of action involves:
- Sodium Feredetate: Replenishes iron stores, essential for hemoglobin synthesis, the protein in red blood cells responsible for oxygen transport.
- Folic Acid: Essential for DNA synthesis, cell division, and red blood cell production. It prevents and treats folate-deficiency anemia.
- Vitamin B12 (Methylcobalamin): Plays a critical role in nerve function, DNA synthesis, and red blood cell maturation. It’s crucial for cell multiplication, blood formation, and protein synthesis. It helps manage neuropathies and certain psychiatric disorders.
Alternate Names
While no specific alternate names exist for this exact combination, each component has its own:
- Folic Acid: Vitamin B9, Folate
- Sodium Feredetate: Sodium ferric ethylenediaminetetraacetate
- Vitamin B12: Cobalamin, Cyanocobalamin, Methylcobalamin (a form of B12).
Brand names vary depending on the manufacturer and region. Some examples include: Solfe, Feredet, and others.
How It Works
Pharmacodynamics:
- Sodium Feredetate: Provides iron for hemoglobin synthesis, increasing red blood cell count and oxygen-carrying capacity. It is less likely to cause gastrointestinal irritation compared to other iron salts.
- Folic Acid: Converted to tetrahydrofolic acid, a coenzyme for various metabolic processes, particularly purine and pyrimidine synthesis, essential for DNA and RNA formation.
- Vitamin B12: As a coenzyme, it participates in DNA synthesis, red blood cell maturation, and myelin formation (protective nerve covering). It is also involved in the metabolism of carbohydrates, fats, and proteins.
Pharmacokinetics:
- Sodium Feredetate: Absorbed in the duodenum and jejunum. The iron is released and binds to transferrin for transport.
- Folic Acid: Absorbed in the jejunum. Metabolized in the liver and stored as polyglutamates.
- Vitamin B12: Requires intrinsic factor for absorption in the ileum. Stored primarily in the liver.
Elimination:
- Sodium Feredetate: Excess iron is excreted primarily through feces, with minimal renal excretion.
- Folic Acid: Eliminated mainly through urine and feces.
- Vitamin B12: Excreted primarily through bile, with some renal excretion.
Dosage
Dosage and duration are determined by the physician based on individual patient needs, such as age, weight, severity of anemia, and response to treatment.
Standard Dosage
Adults: Typically, one tablet/capsule daily, taken with or without food.
Children: Dosage adjustments are necessary for children under 12 years old, always consult with a pediatrician for appropriate dosing guidance.
Special Cases:
- Elderly Patients: Standard adult dose unless renal or hepatic impairment is present.
- Patients with Renal Impairment: Dose adjustment may be needed based on the degree of impairment.
- Patients with Hepatic Dysfunction: Caution is advised; dose adjustment may be necessary.
Clinical Use Cases
Dosage adjustments may be required in specific situations:
- Intubation, Surgical Procedures, Mechanical Ventilation, ICU Use, Emergency Situations: Not typically indicated for these clinical situations. The primary use is for treating iron, folate, and vitamin B12 deficiencies.
Side Effects
Common Side Effects:
- Gastrointestinal discomfort (nausea, constipation, diarrhea, stomach upset)
- Dark stools (harmless)
Rare but Serious Side Effects:
- Allergic reactions (rash, itching, difficulty breathing)
Long-Term Effects:
- Iron overload (with prolonged excessive use)
Contraindications
- Hypersensitivity to any component
- Iron overload disorders (hemochromatosis, hemosiderosis)
- Pernicious anemia (unless treated concurrently)
Drug Interactions
- Antacids, proton pump inhibitors, H2 receptor antagonists: Reduced iron absorption
- Antibiotics (tetracyclines, chloramphenicol): Impaired iron absorption and efficacy
- Anticonvulsants (phenytoin): Reduced folic acid levels
- Levodopa: Reduced efficacy of levodopa
- Cholestyramine: Reduced vitamin B12 absorption
Pregnancy and Breastfeeding
Generally considered safe during pregnancy and breastfeeding when used as directed by a physician. However, it’s essential to consult a doctor before use to ensure appropriate dosage and to weigh potential benefits against risks.
Drug Profile Summary
- Mechanism of Action: Replenishes iron, folic acid, and vitamin B12, promoting red blood cell formation and supporting nerve function.
- Side Effects: Generally well-tolerated; common side effects include GI discomfort and dark stools.
- Contraindications: Hypersensitivity, iron overload disorders.
- Drug Interactions: Numerous drug interactions; monitor closely.
- Pregnancy & Breastfeeding: Generally safe when used as directed by a doctor.
- Dosage: One tablet/capsule daily or as prescribed.

Popular Combinations
Often combined with other vitamins and minerals as part of a comprehensive prenatal or nutritional supplement.
Precautions
- Evaluate underlying cause of anemia before starting treatment.
- Monitor for allergic reactions.
- Avoid administering with tea, coffee, or dairy products as these can reduce iron absorption.
- Patients with pre-existing medical conditions (renal, liver, gastrointestinal) require careful monitoring.
