Usage
This combination medication is primarily prescribed for preventing and treating nutritional deficiencies, especially those involving iron, vitamin B12 (cyanocobalamin), and folic acid. It is also used to treat conditions such as megaloblastic anemia (caused by vitamin B12 or folate deficiency), iron-deficiency anemia, pernicious anemia, and general nutritional deficiencies related to poor diet or malabsorption. During pregnancy, it’s used to prevent neural tube defects.
It is categorized under these pharmacological classifications:
- Hematinic: Increases hemoglobin levels
- Vitamin Supplement: Replenishes essential vitamins
- Mineral Supplement: Replenishes essential minerals
Alternate Names
This combination doesn’t have a standard international nonproprietary name (INN) or a universally recognized brand name. It’s often referred to by its individual components or specific brand names depending on the manufacturer. It might be informally called “multivitamin with iron” or “nutritional supplement with B vitamins and minerals.”
How It Works
Pharmacodynamics: Each component has a specific role: Cyanocobalamin is essential for red blood cell formation, nerve function, and DNA synthesis. D-Panthenol converts to pantothenic acid, crucial for energy metabolism. Iron is vital for hemoglobin synthesis and oxygen transport. Folic acid is crucial for DNA synthesis, cell division, and red blood cell production. L-Lysine aids protein synthesis and collagen formation. Niacinamide is involved in energy metabolism and DNA repair. Protein hydrolysate supplies amino acids for protein synthesis. Pyridoxine supports metabolic processes and neurotransmitter synthesis. Zinc sulfate is involved in immune function and enzymatic reactions.
Pharmacokinetics: The components are absorbed through the gastrointestinal tract, though absorption rates vary. Iron absorption, for example, can be affected by factors like food intake. They are metabolized and eventually eliminated through various pathways, including renal and hepatic excretion. Vitamin B12 requires intrinsic factor for absorption.
Mode of Action: The components act through various mechanisms like enzyme cofactors, substrates for metabolic processes, and incorporation into essential molecules (e.g., iron in hemoglobin). For example, vitamin B12 converts to active forms (methylcobalamin and adenosylcobalamin) involved in specific enzymatic reactions. Folic acid is converted to tetrahydrofolic acid, a crucial cofactor in DNA synthesis.
Dosage
Dosage and administration should be individualized based on the patient’s specific needs and clinical condition.
Standard Dosage
Children: Dosage is adjusted based on age and weight. Consult a pediatrician for appropriate recommendations.
Special Cases:
- Elderly Patients: Dose adjustments may be needed based on renal and hepatic function.
- Patients with Renal Impairment: Caution is advised, and dose adjustments may be necessary.
- Patients with Hepatic Dysfunction: Dose adjustments may be needed.
- Patients with Comorbid Conditions: Consider potential interactions with other medications.
Clinical Use Cases
Dosage in specific clinical settings should be determined by the treating physician and tailored to individual patient needs. There is no standard dosing regimen for situations like intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations solely based on this multivitamin combination. These situations often require additional specific interventions.
Dosage Adjustments
Dose adjustments are crucial based on individual patient factors, including renal/hepatic dysfunction, metabolic disorders, and potential drug interactions.
Side Effects
Common Side Effects:
Nausea, vomiting, diarrhea, constipation, dark stools, and abdominal discomfort are possible.
Rare but Serious Side Effects:
Allergic reactions (rash, itching, swelling), iron overload, and other serious adverse effects are rare but possible.
Long-Term Effects:
Long-term effects of high doses of certain components (e.g., iron) can include organ damage. Appropriate monitoring is essential.
Adverse Drug Reactions (ADR):
Clinically significant ADRs require immediate medical attention.
Contraindications
Contraindications may include hypersensitivity to any component, certain anemias (e.g., sideroblastic anemia), hemochromatosis, iron overload, and other specific conditions.
Drug Interactions
Interactions may occur with antacids, antibiotics (e.g., tetracyclines, quinolones), levodopa, and other medications. Food can also affect the absorption of iron.
Pregnancy and Breastfeeding
This combination is often recommended during pregnancy to prevent neural tube defects. It is generally considered safe during breastfeeding. However, consult with a doctor before using any medication during pregnancy or while breastfeeding.

Popular Combinations
This combination may be used alongside other medications as directed by a physician, but there are no “popular combinations” specifically using this multi-ingredient formulation. Individual components are often given in different combinations for specific therapeutic goals.
Precautions
Standard precautions include assessing for allergies, metabolic disorders, and organ dysfunction. Caution should be exercised in pregnant/breastfeeding women, children, and the elderly.
FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for this combination?
A: Dosage varies. Consult the product information and consider individual patient needs.
Q2: Can this be taken during pregnancy?
A: It is often recommended during pregnancy, especially for preventing neural tube defects. Consult with a healthcare professional.
Q3: Are there any common side effects?
A: Gastrointestinal issues like nausea, vomiting, constipation, and dark stools are possible.
Q4: What if I miss a dose?
A: Take the missed dose as soon as you remember, unless it is close to the next scheduled dose. Do not double the dose.
Q5: How should this medication be stored?
A: Store below 25°C.
Q6: Can this combination interact with other medications?
A: Yes. It can interact with antacids, certain antibiotics, levodopa, and other medications. Inform your physician about all other medicines you are taking.
Q7: Is this medication safe for long-term use?
A: Long-term use, especially at high doses, can pose risks (e.g., iron overload). Regular monitoring is essential. Dosage should be adjusted based on individual patient needs and monitored by a healthcare professional.
Q8: What should I do if I experience side effects?
A: Contact your healthcare provider if you experience any adverse effects.
Q9: Can this combination be used to treat pernicious anemia?
A: While it can help address the nutritional deficiencies associated with pernicious anemia, it doesn’t address the underlying cause (lack of intrinsic factor). Other treatments might be necessary.
