Indications & Clinical Uses

Neiratax is employed to correct B‑vitamin deficiencies and to provide local anesthesia for intramuscular procedures.

  • Thiamine (Vitamin B1) deficiency: restores thiamine levels and supports carbohydrate metabolism.
  • Cyanocobalamin (Vitamin B12) deficiency: aids hematologic and neurologic function.
  • Pyridoxine (Vitamin B6) deficiency: assists amino‑acid metabolism and neurotransmitter synthesis.
  • Procedural pain management: lidocaine delivers rapid local anesthesia for intramuscular injections.

How It Works

  • The vitamin components act as essential cofactors in enzymatic reactions: thiamine participates in carbohydrate decarboxylation, cyanocobalamin is required for DNA synthesis and myelin formation, and pyridoxine supports amino‑acid transamination. Lidocaine hydrochloride blocks voltage‑gated sodium channels in neuronal membranes, preventing depolarization and producing a reversible local anesthetic effect at the injection site.

Side Effects

Neiratax may cause a range of adverse reactions following intramuscular administration.

Common Side Effects

  • Injection site pain or erythema
  • Mild nausea or vomiting
  • Transient headache or dizziness
  • Temporary hypotension
  • Mild pruritus or skin rash
  • Feeling of warmth or flushing

Serious or Rare Side Effects

  • Anaphylactic or severe allergic reaction
  • Cardiovascular instability (severe hypotension, arrhythmia)
  • Central nervous system toxicity (seizures, loss of consciousness)
  • Stevens‑Johnson syndrome or toxic epidermal necrolysis
  • Persistent numbness or motor weakness at the injection site
  • Hematologic abnormalities (e.g., thrombocytopenia).

Precautions & Warnings

Before using Neiratax, consider the following safety measures.

  • Assess vitamin deficiency status: confirm need for B‑vitamin supplementation.
  • Allergy screening: avoid in patients with known hypersensitivity to any component.
  • Cardiac monitoring: use caution in individuals with conduction disorders or severe heart disease.
  • Hepatic function: adjust use in patients with significant liver impairment.
  • Pregnancy and lactation: defer use until safety is established.
  • Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Avoid Interactions

Neiratax can interact with other medicines; awareness of the level of interaction helps manage risk.

Major Interactions (Avoid)

  • Concurrent use of other local anesthetics: additive toxicity.
  • Sodium channel blockers (e.g., antiarrhythmics): increased risk of cardiac effects.
  • MAO inhibitors combined with lidocaine: potential hypertensive crisis.

Moderate Interactions (Monitor Closely)

  • Antihypertensive agents: may enhance hypotensive response.
  • CYP3A4 substrates (e.g., certain antiepileptics): altered lidocaine metabolism.
  • Alcohol or CNS depressants: increased sedation or dizziness.
  • High‑dose vitamin B supplements: risk of hypervitaminosis.

Frequently Asked Questions

Neiratax is a sterile injectable that combines three B‑vitamins (thiamine, cyanocobalamin, pyridoxine) with lidocaine. It is used to correct deficiencies of these vitamins and to provide short‑term local anesthesia for intramuscular procedures where rapid pain control is needed.

The vitamin components serve as essential cofactors in metabolic pathways: thiamine supports carbohydrate metabolism, cyanocobalamin is vital for DNA synthesis and nerve health, and pyridoxine assists amino‑acid metabolism. Lidocaine blocks voltage‑gated sodium channels, preventing nerve depolarization and producing a reversible local anesthetic effect at the injection site.

The appropriate dose of Neiratax is determined by the prescribing healthcare professional based on the patient’s clinical condition, age, weight, and the specific indication. Dosage information is provided on the product label and should be followed exactly as directed by the prescriber.

Safety data for Neiratax in pregnancy and lactation are limited. It should be used only if the potential benefit justifies any potential risk to the fetus or infant. Healthcare providers should evaluate each case individually and discuss possible risks with the patient.

To place an order, submit an enquiry on the Neiratax product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including cold‑chain if needed), and any required import documentation.

Neiratax uniquely combines three B‑vitamins with a local anesthetic in a single intramuscular formulation, offering both nutritional supplementation and immediate analgesia. Other vitamin‑B injectables typically contain only one or two vitamins and lack an anesthetic component, requiring separate pain‑management measures for procedures.

Neiratax should be stored at 2‑8 °C in a refrigerator, protected from light, and must not be frozen or shaken. Keep the vial in its original packaging until use and discard any solution that appears discolored or contains particles.

Neiratax is administered by a qualified healthcare professional via intramuscular injection. The injection site should be cleaned with an appropriate antiseptic, and the recommended volume is injected slowly to minimize discomfort and ensure proper absorption of both the vitamins and lidocaine.

Serious risks include severe allergic reactions such as anaphylaxis, cardiovascular instability (significant hypotension or arrhythmias), central nervous system toxicity (seizures, loss of consciousness), and rare dermatologic emergencies like Stevens‑Johnson syndrome. Immediate medical attention is required if any of these symptoms occur.

Neiratax is contraindicated in individuals with known hypersensitivity to any of its components, including lidocaine or the B‑vitamins. It should also be avoided in patients with severe cardiac conduction disorders, significant hepatic impairment, or those for whom the safety of the ingredients during pregnancy or lactation has not been established.
