Jellyfish stings - How to treat themThe dreaded “J” word! Although our beaches here on the Costa del Sol are generally safe for swimming, we sometimes receive visits from unwelcome visitors: Jellyfish.

Under certain conditions, usually after heavy easterly winds and when the sea temperature is warmer than average, these slippery creatures head towards the shoreline and cause havoc amongst swimmers. They aren’t particularly dangerous; however, their sting can be painful and causes discomfort for their unfortunate victim.  They are usually difficult to spot in the water and bathers get stung by coming into contact with the jellyfish’s tentacles.

UPDATE: During the spring and early summer of 2018 the Costa del Sol – and most of the Mediterranean coastline has been ‘invaded’ by the dreaded and dangerous Portuguese Manowar jellyfish (see image below). The persistent westerly winds and currents from the Atlantic have brought these slimy creatures to our shores resulting in the closing of many beaches. Unlike their more common ‘cousins’, this species isn’t common in the Mediterranean; however, their sting causes extreme pain and can cause respiratory problems and even heart failure.

The Portuguese Manowar is easily spotted as it looks like a purple/blue coloured balloon which floats on the surface of the water. Below the surface lie the long tentacles which are so dangerous. If you have kids, beware of these jellyfish being washed up on the shore; their bright colour makes them ideal targets for inquisitive young fingers and the sting is just as lethal when they are dead and washed up on the shore.

Common Symptoms

Jellyfish stings have various common symptoms:

  • Pain
  • Burning Sensation
  • Swelling and redness
  • Bleeding

Symptoms usually remit after a few hours; however, in some cases, if a patient is allergic to the sting or suffers other illnesses, symptoms can be more severe and medical treatment may be necessary.

What to do if you get stung by a Jellyfish

If you get stung by a jellyfish, you are going to know about it! Here are a few things you need to keep in mind after being stung:

  • Clean the area affected by the sting
  • Never use regular water (this could break the stinging cells and cause another sting)
  • Use physiological saline solution (which you can buy in any chemist) or sea water to clean the area affected by the sting
  • Apply cold over the sting; make sure you don’t apply ice directly on the injury, rap it up in a cloth or towel. Do this for about 15 minutes.
  • Remove any remains of a jellyfish tentacle on the skin; make sure you don’t use your bare hands. Use gloves or tweezers or even a credit card.
  • It is standard procedure to apply some form of antihistamine; we recommend you go to the chemist or our hotel doctor and explain what has happened so that they can subscribe adequate treatment.
  • If the pain is very severe or the victim’s state worsens, go to the nearest medical centre as soon as possible.
  • Do not rub the sting with a towel or with sand; this will just make the injury worse.

Common Myths

There are various myths associated with Jellyfish stings and how to treat their stings. Below we’ve highlighted the main ones you want to avoid…

  • Don’t rub sand on the wound. You may have seen this in movies but it’s not a good idea.
  • Don’t use soap to clean the area where you’ve been stung.
  • Don’t rub alcohol on the wound. 
  • Do not urinate on the wound. 

All the above ‘remedies’ only result in the spreading of the venom over the skin and increases the risk of infection (especially using sand or urine).

Another liquid often used to calm the pain of a sting is vinegar. Although this can be effective in treating the stings of some species, it can have adverse effects with others like the Portuguese Manowar. We recommend you stick to the recommended method outlined above.


1)      Look out for flags like the one in the image above. If the lifeguards have put this flag up it means that there are jellyfish in the water and there is a risk of getting stung.

2)      Jellyfish will often get washed up on the shore; make sure you don’t touch them and be careful with kids as their inquisitiveness means they are prone to being stung when playing on the shore.

3)      There is a special cream which acts as protection against sunburn and jellyfish stings. Apparently, it includes a plankton extract that acts on 4 different levels to avoid triggering the jellyfish’s stinging mechanism with the following results:

  • Causes jellyfish tentacles to slip over your skin
  • It confuses the sensors in the stinging cells; this leads them to believe they are touching another jellyfish
  • Blocks communication between the sensors and the cell body
  • Releases inhibitors which prevent the unleashing of stinging darts.

The cream is available for children and for adults and should be available at local chemists. (I’d love to know if it actually works… let us know if you’ve tried it and whether it was effective by posting in the comments below)

4) If you are staying on the Costa del Sol, there is a Jellyfish mobile app you can download for your smartphone which lets you know the state of all the beaches on the coast and whether or not there are any jellyfish in their waters.

Well, you are now equipped to deal with these annoying creatures which can potentially ruin a pleasant afternoon on the beach. Luckily these jellyfish rarely appear, but at least you’ll know what to do if you do happen to come across them on your travels!
