This is a sterile injectable local anaesthetic solution containing Lignocaine Hydrochloride, a fast-acting amide-type anaesthetic agent that provides temporary nerve block for pain relief. It is combined with Adrenaline (as Adrenaline Bitartrate), a vasoconstrictor that prolongs the duration of anaesthesia, reduces systemic absorption of lignocaine, and minimizes local bleeding.

This combination is used in veterinary procedures requiring regional or local anaesthesia, particularly in surgeries and wound treatments.

•  Adrenaline Bitartrate equivalent: 0.009 mg per mL

•  Sodium chloride

•  Sodium metabisulfite (as antioxidant)

•  Hydrochloric acid or sodium hydroxide (for pH adjustment)

•  Water for injection

•  Local anaesthetic with vasoconstrictor

•  Veterinary injectable anaesthetic agent

•  Local or regional anaesthesia during minor surgical and diagnostic veterinary procedures

•  Dental extractions

•  Suturing of wounds

•  Minor skin surgeries

•   Nerve blocks or infiltration anaesthesi

Dosage must be individualized by the attending veterinarian. General guidelines:

•  Large animals (Cattle, horses): 5–20 mL depending on site and depth

•  Small ruminants (Sheep, goats): 2–5 mL

•  Dogs, cats: 0.5–5 mL

•  Maximum total dose of lignocaine: Not to exceed 4 mg/kg body weight

•  Use the lowest effective dose

•  Infiltration

•  Nerve block

•  Epidural (in certain formulations)

•  Intra-articular or intravenous regional anaesthesia (IVRA) (Always under expert veterinary guidance)

•  Sterile injectable solution

•  Available in amber glass vials of 30 mL

Used for short-term anaesthesia in various veterinary species, especially for minor surgeries, dental procedures, wound management, and local blocks in livestock and companion animals.

•  Rapid onset of local anaesthesia

•  Adrenaline prolongs anaesthetic effect and reduces blood loss

•  Minimizes need for systemic anaesthesia

•  Reduced systemic absorption = lower toxicity risk

•  Allows quick, field-based procedures without general anaesthesia

•  Local irritation or tissue necrosis (rare)

•  Systemic toxicity (tremors, hypotension, CNS effects) if dosage is exceeded or injected intravascularly

•  Allergic reactions (sulphite sensitivity due to preservative)

•  Delayed wound healing at injection site due to vasoconstriction

Prescription-only veterinary pharmaceutical (Rx).

Use under licensed veterinary professional supervision only.

•  Always aspirate before injecting to avoid intravascular administration

•  Avoid use in extremities where circulation is compromised (due to vasoconstrictor)

•  Use cautiously in animals with cardiac issues or hypersensitivity

• Avoid exceeding recommended dose

•  Discontinue if signs of systemic toxicity occur

•  Meat: 3 days (recommended)

•  Milk: 48 hours (recommended) (Subject to local regulations — always verify with veterinary authority)

•  Store below 25°C in a cool, dark place

•  Protect from light

•  Do not freeze

•  Discard unused portion after opening

•  Use aseptic technique when drawing and administering

•  Do not use if solution is discoloured or contains particulate matter

•  Dispose of used vials and materials according to veterinary biomedical waste regulations

•  HS Code: 3004909099

•  HSN Code: 3004 (Medicaments containing mixed or unmixed products for therapeutic or prophylactic use)

•  Use only under strict veterinary supervision

•  Do not mix with other injectable agents unless compatibility is verified

•  Not for use in animals with known hypersensitivity to amide-type anaesthetics or sulphites

•  Strictly for veterinary use only

•  Not intended for human use due to dosage, formulation, and regulatory differences

Q1: What is the role of Lignocaine in this injection?

Lignocaine acts as a fast-acting local anaesthetic that temporarily blocks nerve signals, providing pain relief during minor procedures.

Q2: Why is Adrenaline included?

 Adrenaline constricts local blood vessels, which slows absorption of lignocaine, prolongs its effect, and minimizes bleeding.

Q3: Is this injection safe for all animals?

Yes, when used at recommended doses under veterinary supervision. Caution is required in animals with cardiac conditions.

Q4: What is the maximum safe dose of Lignocaine?

Not more than 4 mg/kg body weight in most animals. Exceeding this may cause toxicity.

Q5: Can this be used during pregnancy in animals?

Only if deemed essential by the attending veterinarian.

Q6: Is a withdrawal period necessary?

Yes, 3 days for meat and 48 hours for milk are generally recommended.

Q7: Can this be given IV?

Not directly. It is meant for local or regional administration. IV use of lignocaine is only for specific indications and formulations.
