Snake Bite Guide

Snake Bite — Venom Response

Proper first aid for snake bites to slow venom spread and prevent complications.

Get to a Hospital as Fast as Possible

Call 911/112 or get to the nearest emergency room immediately. Antivenin treatment must be given within hours. Try to remember the snake's color, shape, and size — but do NOT try to catch or kill it.

Step-by-Step Instructions

1

Move Away From the Snake

Get the person (and yourself) away from the snake safely. Snakes can strike again. Do not try to handle or kill the snake.

2

Keep the Person Still and Calm

Movement increases blood flow and spreads venom faster. Have the person lie down and keep the bitten limb as still as possible, ideally at or below heart level.

3

Remove Jewelry and Tight Clothing

Remove rings, watches, bracelets, and tight clothing near the bite site before swelling begins.

4

Clean the Wound Gently

Clean the bite with soap and water if available. Cover with a clean, dry bandage. Do not apply ice or a tourniquet.

5

Mark the Swelling Edge

Use a pen to mark the edge of swelling and note the time. This helps doctors track venom progression. Re-mark if swelling spreads.

6

Get to the Hospital

Transport the person to the nearest emergency room as quickly as possible. Carry them if possible — they should not walk.

Do's and Don'ts

Do's

  • Keep the person still and calm
  • Remove jewelry near the bite before swelling
  • Keep the bitten limb at or below heart level
  • Note the snake's appearance if possible (or take a photo from a safe distance)

Don'ts

  • Don't suck out the venom — this doesn't work and can cause infection
  • Don't apply ice or a tourniquet
  • Don't cut the wound open
  • Don't give alcohol, aspirin, or caffeine
  • Don't try to catch or kill the snake

Aftercare

Hospital treatment may include antivenin, wound care, tetanus booster, and blood tests to monitor clotting and organ function.
Recovery time varies from days to weeks depending on the type of venom and severity. Follow up with your doctor for wound checks.
Wear boots and long pants when hiking. Watch where you step and reach in snake-prone areas.
