Jellyfish Treatments and Prevention
Searching online will yield a wide range of suggestions for what to do in the event of a jellyfish sting. Some of the best suggestions we’ve seen include the following:
1. Seek medical attention as soon as possible if in shock or if you have any complications.
2. Rinse the site with vinegar to deactivate the toxins and help remove the remaining tentacles and nematocysts. Others say to wash the area with seawater to deactivate stinging cells. Or you can remove tentacles by scraping with a credit card or other plastic object.
3. Use hot water or ice packs to reduce the pain duration and intensity. Others suggest after removing the tentacles, immerse the affected arm or leg in hot water of 104 to 113°F for at least twenty minutes. If other body parts are impacted, a hot shower can be used instead.
