Each kit contains a syringe-like device that exerts one atmosphere of reverse pressure. The device extracts the venom from the wound without the complications or bleeding or wound contamination.

Other symptoms can include excessive salivation, thirst, swollen eyelids, blurred vision, muscle spasms and unconsciousness. Rattlesnake venom also interferes with the ability of the blood to clot properly. Severe symptoms can be life-threatening and must be treated with antivenin, a prescription medication. Antivenin is given intravenously with fluids. Other therapy may include numerous laboratory tests, antibiotics and an update on the tetanus shot, if needed.
