Before Calling Emergency:

Have this information ready:

  • Person's age, weight, and condition
  • Type of sea animal
  • Time of the sting
  • Location of the sting
Poison Control:

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.

They will tell you if you should take the person to the hospital. They will also tell you how to do any first aid that can be given before you get to the hospital.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

What to Expect at the Emergency Room:

The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. The wound will be soaked in a cleaning solution and any remaining debris will be removed. Symptoms will be treated. Some or all of these procedures may be performed:

  • Blood and urine tests
  • Breathing support, including oxygen, tube through the mouth into the throat, and breathing machine
  • EKG (electrocardiogram, or heart tracing)
  • Intravenous fluids (through a vein)
  • Medicine called an antiserum to reverse the effect of the venom
  • Medicine to treat symptoms
  • Tetanus shot, if necessary
  • X-rays
Outlook (Prognosis):

The outcome often depends on how much poisonous venom entered the body, the location of the sting, and how soon the person receives treatment. Numbness or tingling may last for several weeks after the sting. Skin breakdown is sometimes severe enough to require surgery.

A puncture in the person's chest or abdomen may lead to death.
