Product Overview

Tiger/Multi-Brown Snake Antivenom 7000IU (minimum) 3000IU Tiger Snake Antivenom/4000IU Brown Snake Antivenom

With less than 1 in 5 snakes being able to be correctly identified by the Australian public, this product minimises the need for precise identification as it neutralises the venom from more than a dozen snake species. This product allows Veterinary Practices to be prepared for almost any snakebite eventuality. When you take into consideration the longest shelf life in the market at 30 months it makes sense to always have a bottle in the fridge.

Animals may present a wide difference of clinical signs. Suddenness of onset can depend on bite location, size of snake and amount of envenomation. Clinical signs commonly observed include: muscular weakness, ataxia or flaccid paralysis, dilated pupils, respiratory distress, trembling, salivation and vomiting, slower blood clotting time, haemolysis and haemoglobinuria.

Direction of Use

To be used by, or under supervision of, a registered Veterinary Surgeon only.


For optimum use the IV route must be used. Absorption from the SC or IM route is too slow for an efficient response. For safety against anaphylactic reactions it is best to give the dose in diluted form (dilution 1 in 10 in Hartmannís solution is recommended) over a 30 minute period, as well as having adrenaline, antihistamine and steroids on hand to treat any reactions if they occur. An appropriate dose of non-sedating antihistamine should be given before infusion and a small prophylactic SC dose of adrenaline is also advisable.

Dosage and Aministration

The amount of antivenom required depends on the likely amount of venom injected. This in turn will depend on a number of factors such as the number of strikes and their effectiveness, the size of snake and fullness of the venom glands. The amount of antivenom given will rely on the clinical judgement of the physician carrying out the treatment. The response will depend on the time taken between envenomation and administration of the antivenom. Delayed treatment results in a much slower response and can allow rapid damage to the body systems with symptoms only being slowly negated.

An initial dose of 3000 units of Tiger Snake Antivenom (ie. the contents of this vial) is recommended for all snakes other than Brown Snake. Where a Brown Snake has been positively identified, an initial dose equivalent to 1000 units of Brown Snake antivenom may be sufficient. Further doses should be given if required.

The animal should be kept warm in a dark, quiet environment. If comatose, the patient should be intubated to assist in breathing and the maintenance of a clear airway. IV fluid therapy should be initiated as soon as possible to assist renal function in removing toxins and damaged red blood cells. Antivenom can be given in this diluted state which improves the safety of the product against anaphylactic-like reactions. This can be given over a 30 minute period.
