Local Anaesthetic with Quick Change Cartridge (QCC) Technology

Designed for safety and speed in the farm environment.

What is NumOcaine?

NumOcaine is the approved local anaesthetic for Numnuts. It works by affecting the permeability of nerve cell membranes to sodium ions, thus blocking nerve impulse transmission. All nerves are effected but those concerned with pain and temperature are most sensitive. Onset of action is rapid when given by injection.

Give them targeted pain relief

Engineered to work around your current process for tail docking and castration with elastrator rings. NumOcaine comes in 100mL bottles, giving roughly 65 procedures per bottle


The QCC technology removes the need for cumbersome tubes.

Fast Setup

QCC technology enables fast broaching and attachment to the Numnuts device.


The QCC acts as tamper security so you know you’re buying genuine NumOcaine. It also limits access to the local anaesthetic when not attached to a Numnuts device.

How to use

It’s designed to be simple and fast. Simply push the orange cap down to broach the bottle and twist the bottle onto the Numnuts device.

To prime, open the tool lightly and press the plunger 2-3 times until you see the fluid chamber fill up.

How to purchase

Currently, the Numnuts system (including NumOcaine) is only available in Australia. Under APVMA regulations, NumOcaine is classified as an S4 drug, and so can only be supplied by a Vet. 

Contact your usual vet (the vet you already have a relationship with) to arrange your NumOcaine supply. If they are not already a NumOcaine stockist they can quickly and easily register with us using our online form. If you do not already have an ongoing vet relationship, you can use our Interactive Vet Map to locate a local NumOcaine Vet stockist.

Please be aware that a vet must have a ‘bona fide‘ professional relationship with you to be able to prescribe NumOcaine to your flock, as per AVPMA regulations.
