What is the first aid treatment for stings from jellyfish?

The first aid treatment for jellyfish stings involves the use of a neutralizing agent, which is often vinegar (acetic acid). This is effective because it helps to neutralize the venom released by some species of jellyfish. By applying vinegar to the sting site, it can prevent further nematocysts (stinging cells) from firing and releasing more venom.

In contrast, using ice packs can numb the area but does not address the venom itself. Freshwater rinses can actually trigger more nematocysts to release venom because they can cause the stinging cells to fire. Antibiotics are not relevant in this situation unless there is an infection, but they do not treat the initial sting or venom reaction. This makes the use of a neutralizing agent the most effective and appropriate first aid treatment for jellyfish stings.
