Some of the most common jellyfish encountered in Galveston include the Moon Jellyfish (Aurelia aurita), which are recognizable by their translucent, saucer-shaped bodies and delicate, trailing tentacles.

How do you treat a jellyfish sting in Galveston?

If you or a loved one has sustained a jellyfish sting, here’s what to do:

  • Gently pull out visible tentacles with fine tweezers.
  • Immerse the affected area in hot (not scalding) water until the pain subsides—this may take 20 to 45 minutes.
  • Apply a hydrocortisone cream to the affected area once or twice a day.

Treating a jellyfish sting in Galveston, or anywhere else, requires a few essential steps to alleviate the discomfort and minimize the risk of complications. Here’s a guide on how to effectively manage a jellyfish sting:

Rinse with Vinegar: If available, pour vinegar over the affected area. Vinegar can help deactivate the jellyfish’s stinging cells and alleviate pain. You can also use salt water if vinegar is not on hand.

Remove Tentacle Fragments: Carefully remove any tentacle fragments stuck to the skin using a pair of tweezers or the edge of a credit card. Avoid touching the tentacles with your bare hands to prevent further stings.

Immerse in Hot Water: Soak the affected area in hot (but not scalding) water for 20-45 minutes. The heat helps to denature the toxins and reduce pain. The water should be around 104-113°F (40-45°C).

Over-the-counter Pain Relief: Take over-the-counter pain relievers like ibuprofen or acetaminophen to manage pain and inflammation.

Seek Medical Attention: For severe reactions or allergic symptoms, such as difficulty breathing or a widespread rash, seek immediate medical help.

Watch for Infection: Monitor the wound for signs of infection, like redness, swelling, or pus, and consult a doctor if necessary.

While these steps provide general guidance, it’s advisable to consult local medical authorities and follow any specific advice they provide for treating jellyfish stings in the Galveston area.
