Jellyfish Sting

Marine envenomation first aid varies by species

Step by Step

First aid varies by species and region, so follow local lifeguard and health service guidance. Get out of the water and rinse the area with seawater, not fresh water. Remove any tentacles with tweezers or a gloved hand. For many stings, soaking in hot water that is comfortable to touch, or using a hot pack, can ease pain. In tropical waters where box jellyfish occur, such as northern Australia, vinegar is poured on the sting to deactivate remaining stinging cells and emergency services are called. Do NOT rub the area or apply urine or alcohol. Call emergency services for breathing difficulty, chest pain, severe pain, collapse, or signs of an allergic reaction, and be ready to start CPR.
