Neurobion (Thiamine Hydrochloride, Cyanocobalamin, Pyridoxine Hydrochloride)

• Neurobion is used to address vitamin B complex deficiencies and related neurological or hematological conditions.
• Vitamin B1, B6, and B12 deficiency: restores normal levels of essential B‑vitamins, supporting metabolic pathways, nerve function and red blood cell formation.
• Peripheral neuropathy associated with B‑vitamin deficiency: alleviates nerve pain, tingling and weakness by replenishing cofactors needed for nerve repair.
• Anemia due to vitamin B deficiency: improves erythropoiesis and corrects macrocytic or megaloblastic anemia through enhanced DNA synthesis.

• Neurobion delivers thiamine (B1), pyridoxine (B6) and cyanocobalamin (B12), which act as essential co‑factors for enzymes involved in carbohydrate metabolism, amino‑acid conversion and DNA synthesis. These vitamins support mitochondrial energy production, neurotransmitter synthesis and myelin formation, correcting deficiency states and promoting normal nerve and hematopoietic function. The injectable form provides rapid bioavailability and efficient tissue uptake.

Neurobion may be associated with a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Injection site pain or erythema: mild discomfort at the intramuscular site.
• Nausea or mild gastrointestinal upset: transient after administration.
• Headache: occasional, usually resolves without intervention.
• Dizziness or light‑headedness: brief episodes post‑injection.
• Flushing or warmth sensation: transient skin reaction.
• Mild fatigue: temporary feeling of tiredness.

Serious or Rare Side Effects

• Anaphylaxis: severe allergic reaction requiring immediate medical attention.
• Severe hypersensitivity: including rash, bronchospasm or angioedema.
• Thrombophlebitis: inflammation of the vein at the injection site.
• Significant hypotension: sudden drop in blood pressure after injection.
• Hemolytic reactions: rare, especially in patients with underlying hemolytic disorders.

• Neurobion should be used with careful clinical consideration and monitoring.
• Allergy assessment: verify no known hypersensitivity to any B‑vitamin component.
• Pregnancy and lactation: use only if benefits outweigh potential risks, as safety data are limited.
• Renal or hepatic impairment: monitor closely; dose adjustments may be required.
• Concurrent vitamin therapy: avoid excessive dosing of B‑vitamins to prevent toxicity.
• Medical supervision: administration should be performed by a qualified healthcare professional.
• Store at 2‑8 °C: keep refrigerated, protect from light, do not freeze or shake.

Neurobion may interact with certain medications; monitoring is advised.

Major Interactions (Avoid)

• Methotrexate: may increase risk of hematologic toxicity.
• Phenytoin: can reduce pyridoxine levels, diminishing therapeutic effect.
• Cimetidine: may interfere with vitamin B12 absorption.

Moderate Interactions (Monitor Closely)

• Tetracycline antibiotics: may affect vitamin B absorption.
• Oral contraceptives: may alter vitamin B metabolism.
• High‑dose folic acid: can mask B12 deficiency symptoms.
