Neiratax (Thiamine Hydrochloride, Cyanocobalamin, Pyridoxine Hydrochloride, Lidocaine Hydrochloride)

Neiratax combines vitamins and a local anesthetic, addressing nutritional deficiencies and providing short‑term anesthesia.

• Vitamin B1 deficiency: restores thiamine levels and supports carbohydrate metabolism.
• Vitamin B12 deficiency: replenishes cyanocobalamin for red blood cell formation and neurological health.
• Vitamin B6 deficiency: supplies pyridoxine for amino‑acid metabolism and neurotransmitter synthesis.
• Minor surgical or diagnostic procedures: provides local anesthesia through lidocaine to reduce pain.

• Thiamine acts as a cofactor for enzymes in carbohydrate metabolism, cyanocobalamin participates in DNA synthesis and neurologic function, and pyridoxine supports amino‑acid metabolism and neurotransmitter production. Lidocaine blocks voltage‑gated sodium channels in neuronal membranes, preventing depolarization and producing reversible local anesthesia.

Neiratax may cause a range of adverse reactions.

Common Side Effects

• Injection site pain: mild to moderate discomfort at the site.
• Nausea: transient feeling of queasiness.
• Headache: mild headache following administration.
• Dizziness: temporary light‑headedness.
• Local irritation: redness or swelling.
• Transient numbness: temporary loss of sensation.

Serious or Rare Side Effects

• Anaphylactic reaction: severe allergy requiring immediate medical attention.
• Cardiovascular instability: hypotension or arrhythmia.
• Seizures: rare central nervous system excitation.
• Stevens‑Johnson syndrome: severe skin reaction.
• Respiratory depression: difficulty breathing.
• Persistent neurological deficits: prolonged numbness or weakness.

Before using Neiratax, consider the following safety measures.

• Assess vitamin status: evaluate patient’s B‑vitamin levels prior to therapy.
• Monitor hypersensitivity: observe for signs of allergic reaction during and after injection.
• Cardiac caution: use carefully in patients with conduction disorders or arrhythmias.
• Lidocaine allergy: avoid in individuals with known hypersensitivity to amide‑type local anesthetics.
• Renal/hepatic impairment: adjust use in patients with significant organ dysfunction.
• Store at ambient temperature: keep in original container, protect from moisture and light.

Neiratax may interact with other medicines.

Major Interactions (Avoid)

• Other local anesthetics: combined use can increase systemic toxicity.
• MAO inhibitors: concurrent use may potentiate cardiovascular effects of lidocaine.
• High‑dose vitamin B supplements: risk of hypervitaminosis.

Moderate Interactions (Monitor Closely)

• Anticoagulants: monitor bleeding risk due to injection trauma.
• Anticonvulsants: observe for additive CNS effects.
• Beta‑blockers: may enhance bradycardic effects of lidocaine.
