Home Remedies for Jellyfish Stings

Summer brings with it fun days at your favorite seaside beach and people of all ages playing in the ocean. But the fun can end quickly if you or someone you’re with gets stung by a jellyfish.

Jellyfish are a common sea creature, and several species of jellyfish carry poisonous venom in their tentacles as a means of self-defense against predators.

When you come in contact with a jellyfish tentacle, it can cause millions of nematocysts to pierce the skin and inject venom. It’s this venom that makes a jellyfish sting so painful.


According to the National Science Foundation, 200,000 people are stung by jellyfish every year in Florida alone and 150 million people worldwide are exposed to jellyfish each year (1).

Some common symptoms of a jellyfish sting are burning, stinging and itching sensations on the skin; a tingling or numbness where the sting occurred; throbbing pain that radiates up a leg or an arm; and the skin in the area of the sting turning red or purple.

At times, one may experience severe symptoms like nausea, dizziness, vomiting and difficulty breathing. In such a case, immediate medical attention is required or it can become fatal.


The severity of the symptoms depends on the type of jellyfish that stings you and the number of nematocysts in your skin. The two most dangerous types of jellyfish are the box and the Irukandji jellyfish, both of which are only found in the Pacific Ocean near Australia.

Most jellyfish stings get better with home treatment. In fact, there are many simple and effective remedies that can help remove the venom and provide quick relief from the symptoms.

Here are the top 10 home remedies for jellyfish stings.

1. Calmly Get Out of the Water

As soon as you know that you’ve been stung by a jellyfish, do not panic and get out of the water as calmly as possible. Seek land to avoid being repeatedly stung, which can make things really bad.

As you get out of the water, do not scratch the sting-site or touch it with your hands. When touched with bare hands, the tentacles that may still be attached to your skin will only get you stung more.

Once you are in a safe area, rinse the sting with sea water to wash away any clinging tentacles or stinging tissue. Do not use fresh water, it is believed to activate the nematocysts.

Avoid rubbing the area with a towel after rinsing, as this can activate any remaining stingers.

2. Rinse with Vinegar

After leaving the water and rinsing the site of the sting with sea water, the next step is to immediately rinse it with vinegar. White vinegar should reduce the pain and deactivate the toxin.

A 2017 study published in Toxins concludes that rinsing with vinegar before applying heat is the most effective treatment for jellyfish stings (2).

  1. Rinse the affected area with vinegar for at least 30 seconds.
  2. Carefully pluck out visible tentacles with a fine tweezers. Do not touch the tentacles directly!
  3. Soak the skin in hot water that is between 110° and 113° F (43° to 45° C). Keep the affected skin immersed or in a hot shower for 20 to 45 minutes.

If the vinegar feels too strong, you can dilute it with salt water. Do not use fresh water to dilute it, as this will irritate the stings even more.

3. Hot Water Immersion

After the initial treatment, a hot water immersion is highly recommended.

The high temperature will help deactivate the venom and help decrease the burning sensation from the sting.

A 2006 study published in the Medical Journal of Australia reports that immersion in water at 113° F (45° C) for 20 minutes is an effective and practical treatment for pain from bluebottle jellyfish stings (3).

  1. Heat a few cups of water to between 110° and 113° F (43° to 45° C).
  2. Put some salt in the water and stir well.
  3. Soak the affected area in the salt water for 10 minutes at a time.
  4. Repeat as needed.

4. Apply a Cold Compress

After the initial treatment is done, you can use a cold compress to reduce pain and swelling.

The cold temperature has a numbing effect, which helps reduce the sensation of pain. It will also reduce swelling and inflammation by numbing the nerves.

  • Soaking the affected area in cool water may also help. Repeat as needed.

Caution: Never put ice directly on the skin, as it can cause frostbite.

5. Baking Soda

To neutralize the nematocysts and their venom, you can also use baking soda.


It acts as a natural acid neutralizer that helps reduce the effect of the jellyfish’s venom. This in turn lessens the itching as well as the risk of infection.

  • Another option is to use an over-the-counter witch hazel lotion on the affected area.

10. Wear Protective Clothes

Jellyfish typically only pose a threat to bare skin, which means that protective clothing can prevent most stings. So, when swimming or diving in areas where there’s a risk of being stung, wear a wet suit or other protective clothing.

A 2009 study published in the Journal of Coastal Research reports that protective clothing for marine stinger safety is a must. The study found the fabric Lycra to be the best choice for routine-use, stinger-protective clothing (4).

Also, opt for protective footwear, as stings can also occur while wading in shallow water.

Additional Tips

  • Another safe and effective way to avoid jellyfish stings is to use a lotion designed to repel and protect against them.
  • If you’re stung, do not rinse the wound with fresh water, alcohol or methylated spirits. The change in pH can cause the nematocysts to release more venom.
  • Do not treat jellyfish stings with urine, as it can actually cause the nematocysts to release more venom.
  • Do not use bare hands to pull off any tentacles stuck in the skin. To remove stingers that did not fall away after rinsing the area, use tweezers and carefully pluck them out.
  • Don’t scrape, rub or shave a jellyfish sting.
  • A hydrocortisone cream can be used to reduce inflammation.
  • Apply castor oil to the jellyfish sting every day until the sting starts to heal. Use a cotton ball to apply the oil.
  • Rub an antihistamine cream onto the sting if you experience excessive redness or swelling, or if you get hives.

  1. The sea is a different and wonderful world that we sometimes take for granted, and over exploit for our recreation and survival. We must remember that it isn’t our home and many mysteries still exist about it, and it’s inhabitants that the average vacationer isn’t aware, or knowledgeable about. We are guests in a very different ecosystem that can lead to awkward or dangerous encounters, especially if we are inland dwellers, and not familiar with the risks verses fun at the beach. Most natives from those areas who frequent the ocean activities are wearing wet suits and somewhat protected, while the smarter vacationers swim in their hotel pools. Knowledge and prevention, heeding warnings and alerts, go a long way to help not needing this great article. Remembering that you’re not alone when you jump in the ocean, and that it’s not your home will help too! Aerial photos of beaches often show sea creatures very close to beach goers, without incident or awareness, so respect that you are only a guest, and take any tips offered from local people, who know, and live there with the sea as their neighbor.
