There venom has the same toxic properties of a few Crotalus species but there rear fangs and small venom gland make it less dangerous then a rattlesnake. Personaly i would think that a bite from a false Water Cobra that was adult size and gave a feeding bite could put you in bed for a few days. Im not saying completley treat is like a rattlesnake or other hots but know what you can get away with.Some people mite say there less dangerous than they are but read this bite report of a man that took an alergic reaction and you tell me if they can be dangerous. But gefore you read there not normaly this dangerous but it can happen


Background: Hydrodynastes gigas is a South American, rear fanged venomous colubrid snake. It is commonly referred to as the South American False Water Cobra because of its ability to rise and spread an extended hood. Mice studies have shown the venom and saliva to be hemorrhagic and proteolytic. H. gigas is an imported snake legally sold in the US. This is the first reported case of a symptomatic H. gigas envenomation. Case Report: An 18-year-old male pet store employee was bit on the left wrist by an H. gigas. The snake remained attached for about 1.5 min. The bite caused a small amount of swelling for which he took diphenhydramine twice within 3 hours. He reports receiving several bites previously with no effect. Approximately 9 hours after the bite, he experienced 3 brief episodes of muscle paralysis causing him to fall, unable to move or speak. At the time of paramedic arrival the swelling progressed from the fingertips to the elbow with numbness but no pain. On arrival to the ED vital signs were: HR 105 with 10 premature atrial contractions/min, RR 18, BP 120/80. The tachycardia resolved within 2 hours. The patient was observed overnight in the hospital with the arm elevated to heart level and received ceftriaxone. Localized symptoms persisted overnight with a slight increase in edema and pain to touch. Coagulation lab results remained normal (WBC 10.1, Hgb 16.1, Hct 43.5, Plts 210,000,000, Neut. 60%, PT 14.7, PTT 22.8, INR 1.1 fibrinogen 177, d-dimer
