With different types of snake venom, there are different drugs used.
Some antivenoms for snakebites :
In the United States, people use Crotalidae polyvalent immune FAb (an antivenom derived from sheep), which are purified fragments of IgG antibodies taken from sheep were injected with snake venom. This drug helps to detoxify snake bites very quickly, but how effective it is depends on the time and dose used.
The drug is effective even when injected 24 hours after being bitten, but it is recommended that the snake antidote should be given as soon as possible. Tests on patients show that this snakebite drug has few side effects on patients.

If no side effects are noted, continue with the remainder of the infusion. When the patient's symptoms are not completely stabilized, repeated infusions can be given. Medicines can be used to treat snake bites in children. To treat rattlesnake venom in North America, a equine antigen called Fab2 immunogenic Crotalidae is used.
Dosage: It is recommended to start with 10 vials diluted with 250ml of saline solution and then slowly intravenously infuse 25-50ml/hour for 10 minutes. If there are no adverse effects, continue infusion at a maximum rate of 250ml/hour until the patient is stable. Depending on the patient's condition, consider repeating the initial dose every hour.

Do not apply cold or apply chemicals to the wound until it has been treated properly. Do not bandage the bitten area too tightly because it interferes with blood circulation to the injured area. Long gating time combined with strong garo force can lead to the risk of necrosis of the damaged area. Arbitrarily injecting incisions, squeezing blood will make the venom penetrate the body faster and cause blood loss for the patient. Avoid using stimulants when bitten by a venomous snake because it increases the ability to absorb the venom. When detecting a snake bite, try to remember the characteristics of that snake to describe it to the treating doctor, helping the doctor to identify the type of venom and then have the appropriate treatment. Trying to catch a snake can lead to more accidental bites by snakes. Snake venom is very dangerous to humans because it is potentially fatal.
