Product Overview

Multi-Brown Snake Antivenom 1650IU (minimum)

Multi-Brown Snake Antivenom 1650IU provides an economical effective treatment against the three main species of Brown snakes that are found in Australia. These three species of snake, the Eastern Brown, Western Brown, and the Dugite account for 76% of snakebites in Australia. How this product is unique is that the donor horses have been directly exposed to all three species during the hyper immunisation process whereby normally the hyper immunisation process only involves the Eastern Brown. We believe this unique hyper immunisation process makes our product much more effective against all brown snakes, not just the Eastern Brown. Again this product has a 30 month shelf life, the longest in the market, thus providing a long life product at low cost that will treat 76% of snake bites in Australia.

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.

Directions of Use

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

Precautions

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 the 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 1650 units of Multi-Brown Snake antivenom is recommended. 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.
