Neuromultivit (Thiamine Hydrochloride, Cyanocobalamin, Pyridoxine Hydrochloride)

Neuromultivit, a B‑complex vitamin supplement, supports metabolic pathways that depend on B‑vitamins.

• Thiamine (vitamin B1) deficiency: restores normal carbohydrate metabolism and reduces fatigue, neuropathy and cardiac symptoms.
• Cyanocobalamin (vitamin B12) deficiency: improves red blood cell formation and neurological function in patients with pernicious anemia or malabsorption.
• Pyridoxine (vitamin B6) deficiency: normalizes amino‑acid metabolism and alleviates dermatitis, irritability and convulsions.

• Thiamine, cyanocobalamin and pyridoxine function as co‑enzymes for multiple enzymatic reactions. Thiamine pyrophosphate participates in decarboxylation of α‑keto acids, facilitating carbohydrate oxidation. Cyanocobalamin is required for methionine synthase and methylmalonyl‑CoA mutase, enabling DNA synthesis and fatty‑acid metabolism. Pyridoxal‑5′‑phosphate, the active form of pyridoxine, acts in transamination, decarboxylation and glycogenolysis, thereby supporting protein, lipid and carbohydrate metabolism.

Intramuscular administration of Neuromultivit may be associated with the following adverse reactions.

Common Side Effects

• Injection site pain: mild to moderate discomfort at the injection site.
• Redness or swelling: localized erythema or edema.
• Headache: transient mild headache.
• Nausea: occasional mild nausea.
• Transient flushing: brief sensation of warmth or redness.

Serious or Rare Side Effects

• Anaphylactic reaction: severe allergic response requiring immediate medical attention.
• Stevens‑Johnson syndrome: rare severe skin eruption.
• Hemolytic anemia: uncommon destruction of red blood cells.
• Severe hypotension: sudden drop in blood pressure post‑injection.

Before using Neuromultivit, consider the following precautions to ensure safe administration.

• Assess deficiency status: confirm laboratory evidence of B‑vitamin deficiency before initiating therapy.
• Monitor for allergic reactions: observe the patient for at least 15 minutes after injection.
• Use with caution in renal impairment: adjust dosing if renal function is markedly reduced.
• Avoid in known hypersensitivity: discontinue if patient has a documented allergy to any component.
• Pregnancy and lactation: evaluate risk‑benefit ratio and consult obstetric guidance before use.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Neuromultivit can interact with certain medicines; awareness of these interactions helps prevent adverse outcomes.

Major Interactions (Avoid)

• Levodopa (with carbidopa): high‑dose vitamin B6 may diminish levodopa efficacy.
• Methotrexate: concurrent use may increase methotrexate toxicity.
• Antimetabolites (e.g., 5‑fluorouracil): may exacerbate hematologic effects.

Moderate Interactions (Monitor Closely)

• Anticonvulsants (phenytoin, phenobarbital): may increase vitamin B6 metabolism, reducing effectiveness.
• Oral contraceptives: may alter pyridoxine levels, requiring monitoring.
• Tetracycline antibiotics: can impair absorption of certain B‑vitamins when given simultaneously.
