Can I use lignocan on dog for local use in wound
Reading File
Lignocan (lidocaine/lignocaine) is a local anesthetic. It can be used topically on dogs for minor wound care, but with important caveats - the concentration and amount matter, as high doses are toxic to dogs. Now let me look up the precise pharmacology and veterinary guidance.

Here is a clear, practical answer:
Can You Use Lignocan (Lignocaine/Lidocaine) on a Dog's Wound?
Yes, lignocaine can be used locally on dogs for wound care, but there are important things you need to know about concentration, amount, and safety.
What Lignocan Is
Lignocan is a brand of lignocaine (lidocaine) - a local anesthetic that numbs the area it is applied to. It is used in veterinary practice routinely for:
- Local infiltration around wounds (before suturing)
- Topical application on mucous membranes
- Regional nerve blocks
- Epidural anesthesia
Is It Safe for Dogs?
Yes, with dose limits strictly observed. Dogs are actually more tolerant of lidocaine than cats.
| Parameter | Dogs |
|---|---|
| Recommended infiltrative dose | 4-6 mg/kg (injected around wound) |
| Maximum safe infiltrative dose | < 8 mg/kg |
| Topical mucous membrane use | Safe in limited amounts |
| Toxic dose (CNS effects) | ~20 mg/kg IV |
For topical application directly on a wound surface, the amount absorbed is low, making it relatively safe as long as you don't over-apply, especially on large open wounds where absorption increases.
Practical Guidelines for Local Use on a Wound
-
Infiltration (injected around wound edges): This is the most effective method. A vet injects 1-2% lignocaine around the wound margins before cleaning or suturing. Stay within the 4-6 mg/kg dose limit.
-
Topical on wound surface: Lignocaine can be applied topically. On mucous membranes it penetrates to ~2 mm depth with 15-20 minutes of numbness. On intact skin, penetration is poor without special formulations (like EMLA cream). On an open wound, absorption is faster - use sparingly.
-
Lidocaine patches (5%): A licensed veterinary product - applied near the wound, provides local analgesia for 60+ hours with plasma levels well below toxic range. This is a very safe option.
Key Precautions
- Do NOT use large amounts on large open wounds - systemic absorption through raw tissue can cause toxicity (tremors, seizures, cardiac arrhythmias).
- Do not use on a dog that will lick the wound without an Elizabethan collar - ingesting lignocaine is harmful.
- Avoid epinephrine-containing formulations (e.g., Lignocan with adrenaline/Lignocan-A) on distal extremities, ears, or tail - can cause tissue necrosis.
- No registered veterinary formulation exists for lignocan specifically; human formulations are used off-label under veterinary guidance.
- Always consult a vet for the correct dose based on your dog's weight.
Bottom Line
Lignocan is safe and effective for local use on a dog's wound when used in appropriate amounts. For a small wound, a limited topical application or vet-administered local infiltration is fine. For larger wounds or any uncertainty, have a veterinarian handle it to avoid dosing errors.
