A doctor at Ysbyty Gwynedd’s Emergency Department has issued advice on how best to treat jellyfish stings after an increase in the number of patients attending the Emergency Department with jellyfish stings during the recent warm weather.
The majority of jellyfish stings do not need any medical attention and can be managed by basic first aid. Dr Jennifer Hulse, Clinical Fellow in Emergency Medicine at Ysbyty Gwynedd, said: “There are three simple first-aid steps to treating jellyfish stings.
“First, remove any jellyfish parts stuck to the skin, as they may continue to release stinging chemicals: brush them away with the edge of a credit card or similar plastic object.
“Avoid touching with your hands, and don’t rub with towels or clothes. Next, rinse thoroughly in salt water. Seawater is perfect for this, just look out for other jellyfish!
“Finally, soak the affected area in hot water or take a hot shower, for at least 30 minutes. The water should be as hot as you are able to tolerate, but be careful to test the temperature for children.
“We no longer recommend using vinegar, and you definitely shouldn’t pee on jellyfish stings, we guarantee this will not help!”
After a jellyfish sting, it is entirely normal to experience burning, throbbing or itching, and the pain may spread out from the affected area.
There may be redness and mild swelling around the site of the sting, and a rash may appear immediately, or after a few hours.
These symptoms can be treated at home with simple painkillers such as paracetamol and ibuprofen, and antihistamines may help if there is itching or a rash – all of these medicines can be purchased over the counter.
“None of the jellyfish species commonly found in UK waters are severely toxic, and most stings are no more serious than a nettle sting. So it’s very rare that we need to see them in the Emergency Department.
“The exceptions are extensive stings to the face or genital area, or very rarely, if an allergic reaction develops: you should seek help immediately if you have trouble breathing, swelling of the face, chest pain, vomiting, severe dizziness or other unusual symptoms following a sting”.
