Brown snake venom contains potent toxins in venom that cause paralysis or muscle weakness. Also present are postsynaptic neurotoxins, which are less potent but more rapid acting than the presynaptic neurotoxins. Brown snake venom also contains potent toxins in venom that interfere with blood clotting, causing consumption of the clotting protein putting victims at risk of major bleeding. Brown snake procoagulants are amongst the most powerful snake venom procoagulants known. No kidney toxins have so far been isolated from brown snake venoms, but renal failure (kidney failure) is a common effect of brown snake snakebites in humans, in cases where there is significant envenoming. Brown snake venom does not contain myotoxins that cause muscle damage.
Tiger snake venom also has the same effects as the Common Brown Snake but it is less potent. Tiger snakes have in their venom presynaptic neurotoxins which cause paralysis.
Red-bellied Black Snake venom consists of neurotoxins, myotoxins, coagulants and also has haemolytic properties. Bites from Red-bellied Black Snakes are rarely life- threatening due to the snake usually choosing to inject little venom toxin, but are still in need of immediate medical attention.
Its venom is the most rapid-acting venom of any snake species and consists mainly of highly potent neurotoxins causing paralysis or muscle weakness.
There is often pain and swelling at the bite site, though this is not always so and a trivial looking bite site does not imply a trivial bite. There may be rapid development of major systemic envenoming, including headache, nausea/vomiting, collapse, convulsions (especially in children), paralysis, defibrination coagulopathy, myolysis and kidney damage. It causes paralysis because of the neurotoxins in its venom.
The Death Adders snake vemon has neurotoxins which cause paralysis and muscle damage. It also causes kidney failure and major bleeding due to toxins that consume blood clotting protein.
