If you are bitten by the Black-necked Amazonian Coralsnake

A venomous snakebite is a medical emergency. Call your local emergency number immediately. In the US, dial 911 or Poison Control at 1-800-222-1222.

Get away from the snake and stay calm. Most bites worsen when people panic or try again to handle the snake.
Call 911 or Poison Control (1-800-222-1222) right away. Antivenom works best when given early.
Note the time of the bite and, from a safe distance, the snake's color and pattern, a phone photo is enough. Do not chase it.
Keep the bitten limb still and at roughly heart level. Sit or lie down and limit movement.
Remove rings, watches, and tight clothing near the bite before swelling starts.
Gently wash the bite with soap and water and cover it with a clean, dry dressing.

Do not

Do not cut the wound or try to suck out the venom.
Do not apply a tourniquet or ice.
Do not drink alcohol or caffeine.
