If you or someone you're with is stung by a jellyfish, it's important to provide first aid promptly to alleviate pain and prevent further complications. This Simple First Aid Guide to Jelly Fish Stings gives first-aid guidance on what to do if you encounter a casualty that has been stung by a jellyfish
How do I treat a jellyfish sting?
Thankfully, jellyfish stings around the UK stings are pretty mild and can be treated easily.
If possible and safe to do so, try to move the casualty out of the water.
Keep the casualty as still as possible, this is to minimise the risk of toxins being released into the body.
Flush the area with seawater.
If possible, remove any tentacles from the skin using tweezers or something similar. Wear gloves if available.
Putting an ice pack on the affected area should help reduce pain and inflammation.
If available, apply shaving cream to the affected area. This can help prevent the spread of toxins.
Use a credit card (or similar) to remove any nematocysts (the small poisonous sacks that may be on the skin)
Paracetamol and ibuprofen can be used to treat pain and swelling.
In the UK, the current advice is that vinegar is no longer recommended for treating jellyfish stings because it can make things worse by activating unfired stinging cells. Other things like baking soda and alcohol should also be avoided. Don’t urinate on the sting. It’s unlikely to help and may make the situation worse.
Remember, prevention is key. When swimming in areas known for jellyfish, consider wearing protective clothing or using a jellyfish-resistant suit, if available. And lastly, always be cautious and aware of your surroundings while in the water.
