Neuromultivit (Thiamine Hydrochloride, Cyanocobalamin, Pyridoxine Hydrochloride)

Neuromultivit is a B‑complex vitamin used to address nutritional deficiencies that affect energy metabolism and nervous system health.

• Vitamin B1 (thiamine) deficiency: restores thiamine levels and reduces symptoms such as fatigue and neuropathy.
• Vitamin B12 (cyanocobalamin) deficiency: supports red blood cell formation and neurological function.
• Vitamin B6 (pyridoxine) deficiency: aids amino‑acid metabolism and neurotransmitter synthesis.
• Normal nervous system function: contributes to the maintenance of healthy nerve conduction and cognitive performance.

• The three B‑vitamins act as essential cofactors for enzymes involved in carbohydrate, protein and lipid metabolism. Thiamine participates in pyruvate dehydrogenase complexes, cyanocobalamin is required for methylmalonyl‑CoA mutase and homocysteine remethylation, and pyridoxine serves as a coenzyme for transaminases and decarboxylases, collectively supporting cellular energy production and neurotransmitter synthesis.

Neuromultivit is generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Mild gastrointestinal upset: nausea, abdominal discomfort.
• Headache: transient and low‑intensity.
• Skin rash: erythematous or maculopapular lesions.
• Metallic taste: temporary alteration of taste perception.
• Dizziness: occasional light‑headedness.

Serious or Rare Side Effects

• Hypersensitivity reactions: urticaria, angioedema, or anaphylaxis.
• Severe cutaneous adverse reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Hematologic abnormalities: pancytopenia in rare cases.
• Hepatic dysfunction: elevated transaminases.
• Neurological signs: peripheral neuropathy worsening despite supplementation.

Before using Neuromultivit, consider the following safety measures.

• Pregnancy: consult a healthcare professional; data are limited.
• Breastfeeding: discuss with a physician as vitamins may be secreted in milk.
• Renal impairment: monitor dosing in severe kidney disease.
• Drug interactions: review concomitant medications for potential effects on vitamin metabolism.
• Allergies: avoid if known hypersensitivity to any B‑vitamin component.
• Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and direct sunlight.

Neuromultivit may interact with certain medicines; monitoring is advised.

Major Interactions (Avoid)

• Methotrexate: high‑dose B‑vitamins may reduce its cytotoxic efficacy.
• Phenytoin: increased metabolism may lower vitamin B6 levels.
• Cimetidine: may impair absorption of cyanocobalamin.

Moderate Interactions (Monitor Closely)

• Vitamin C: high doses can enhance iron absorption, potentially affecting B‑vitamin utilization.
• Iron supplements: competitive absorption may reduce B‑vitamin bioavailability.
• Oral contraceptives: may increase requirement for certain B‑vitamins.
