Snake Bite Poisoning 

In the US, around 5,000 cases of snake bites are reported each year according to the Wexner Medical Center at Ohio State University (Wexner). Snake bites should always be considered a medical emergency and treated as such because bites of venomous snake can be lethal. Bites from non-venomous snakes can be dangerous too as they can lead to an infection or allergic reaction. A number of symptoms can occur because of snake bite poisoning like paralysis, convulsions and pain. Let’s have a look at some poisonous snakes and see how their bites can be treated.

How to Treat Snake Bite Poisoning

1. Immediately Call 911

If you suspect the snake bites you is venomous, the first thing to do is call 911. If the snake is not venomous then treat the wound as a puncture wound. Remember to check the appearance of the snake so that you can explain it to the emergency staff.

2. Protect the Victim

While you are waiting for the medical help to arrive, you can:

  • Move the victim as far away from the snake as possible
  • Get the victim to lie down if the bite is below the heart
  • Keep the victim still so that venom cannot spread
  • Use sterile and loose bandage to cover the wound

But DO Not:

  • Cut the bite wound
  • Try to suck the venom out
  • Apply water, ice or tourniquet
  • Give the victim caffeinated drink or alcohol
  • Immerse the wound in water
  • Pick up or trap the snake


3. Follow-Up Care

  • When treating the bite at home: call a medical professional as the victim might need a tetanus injection. A tetanus booster may have to be given after every 10 years.
  • Snake bite treatment in the hospital depends on the type of the snake: For venomous snake bites, the victim will be given anti-venom; a tetanus shot might be given depending on when the victim was last injected.
