A sting from a Lion’s Mane jellyfish can cause nausea, sweating, cramps, headaches and other symptoms and severe stings should seek urgent medical attention.

If you are stung on a lifeguarded beach – please approach the lifeguards on duty for assistance.

First aid for the treatment of jellyfish stings:

• Ensure you don't get stung yourself when aiding others;
• Remove any attached tentacles with a gloved hand, stick, or towel (none of these available use the tips of your fingers);
• Do not rub the affected area (this may result in further venom release);
• Rinse the affected area with sea-water. When you get home, you can bathe/rinse the area in warm to hot water;
• Apply a ‘dry cold pack’ to the area (i.e. place a cold pack or ice inside a plastic bag and then wrap this package in a t-shirt or other piece of cloth);
• Seek medical attention if there is anything other than minor discomfort.

What not to do:

• Don’t rub the area;
• Don’t rinse with fresh water. Use sea water;
• Don’t urinate (pee) on the sting;
• Don’t use vinegar for the types of jellyfish stings that might happen in Ireland;
• Don’t use alcohol;
• Don’t put on a tight bandage.
