This page contains brief details about the drug , it's indication, dosage & administaration, mechanism of action, related brands with strength, warnings and common side effects.
Background and Date of Approval
Thiamine (Vitamin B1), Methylcobalamin (a form of Vitamin B12), Pyridoxine (Vitamin B6), D-Panthenol (a precursor of Vitamin B5), and Nicotinamide (a form of Vitamin B3) are essential vitamins that play a significant role in maintaining nerve function, energy production, and overall cellular health. This combination is widely used to treat conditions like peripheral neuropathy, vitamin deficiencies, and anaemia.
The FDA approved individual B vitamins for clinical use over several decades, with Thiamine approved in 1941 and Methylcobalamin recognised as a bioactive form of B12 used in therapeutic doses. Clinical trials have consistently demonstrated the effectiveness of this combination in reducing nerve pain, restoring energy levels, and improving metabolic balance. These vitamins are typically prescribed as oral tablets or injections, depending on the severity of the deficiency.
Mechanism of Action of undefined
This combination restores essential vitamins that are crucial for nerve health, metabolism, and tissue repair.
- Thiamine (B1): Converts carbohydrates into energy and prevents nerve damage by maintaining healthy nerve function.
- Methylcobalamin (B12): Supports DNA synthesis and promotes nerve regeneration while reducing homocysteine levels, which can harm blood vessels and nerves.
- Pyridoxine (B6): Produces neurotransmitters that regulate mood, sleep, and pain perception while maintaining normal nerve function.
- D-Panthenol (B5): Enhances the skin barrier, supports wound healing, and contributes to fatty acid metabolism.
- Nicotinamide (B3): Participates in cellular energy production and repairs damaged tissues by reducing inflammation and oxidative stress.
Together, these vitamins alleviate nerve pain, improve metabolic processes, and restore overall vitamin balance in the body.
Uses of undefined
This combination is FDA-approved for the management of:
- Peripheral and diabetic neuropathy
- Vitamin B-complex deficiency
- Anaemia caused by B12 deficiency
- Fatigue and weakness related to malnutrition
- Alcohol-induced nerve damage
- Supportive therapy in chronic illnesses requiring nutritional supplementation
undefined Drug administaration and Dosage available
The combination of Thiamine, Methylcobalamin, Pyridoxine, D-Panthenol, and Nicotinamide is available in oral tablets, capsules, and injectable forms. Oral formulations are typically prescribed for mild to moderate deficiencies, with the recommended dosage being 1-2 tablets daily, preferably after meals. Injectable forms are administered intramuscularly or intravenously for severe deficiencies or when oral absorption is inadequate. The dosage for injectable forms varies depending on the patient’s condition and is usually determined by the healthcare provider. In most cases, injectable therapy is followed by oral supplementation to maintain vitamin levels over time. Dosage adjustments may be required for individuals with pre-existing medical conditions or those taking medications that affect vitamin absorption.

- Severe Allergic Reactions: Avoid in individuals with known hypersensitivity to any component.
- Renal Impairment: Use cautiously in patients with kidney disorders to prevent vitamin accumulation.
- Drug Interactions:
- Anticonvulsants may reduce B-vitamin absorption.
- Prolonged use of metformin may lower B12 levels.
- Pregnancy and Lactation: Safe under medical supervision only.
- Alcohol Consumption: Can interfere with vitamin absorption and reduce therapeutic effects.
Precautions
When using this combination, it is essential to maintain the prescribed dosage to prevent vitamin imbalance or toxicity. Patients with chronic kidney disease or liver disorders should inform their doctor before starting the supplement, as dosage adjustments may be required. Individuals consuming alcohol regularly should limit their intake, as it can hinder the absorption of B vitamins and reduce the effectiveness of the treatment. Pregnant and breastfeeding women should use these supplements only under medical supervision to ensure the safety of the baby. For patients with chronic illnesses or undergoing long-term supplementation, periodic monitoring of vitamin levels is recommended to avoid any adverse effects.
Side Effects
Common Side effects:
- Nausea or vomiting
- Mild stomach discomfort
- Drowsiness or fatigue
- Headache or dizziness
Serious side effects:
- Severe allergic reactions (rash, itching, swelling)
- Nerve pain or tingling (with prolonged use)
- Elevated liver enzymes (rare but possible)
Seek immediate medical attention if any serious side effects occur.
Word Of Advice
To maximise the benefits of this combination, it is best to take it after meals to enhance absorption and minimise stomach irritation. Patients should strictly adhere to the prescribed dosage and avoid self-medication.
