Most jellyfish stings can be treated by rinsing the area with salt water, applying vinegar or a baking soda paste, and taking a pain reliever.
Someone having a severe reaction to a jellyfish sting needs emergency care that may include:
- Cardiopulmonary resuscitation (CPR)
- An epinephrine injection, for anaphylactic shock
- Life support to stabilize breathing, heart rate and blood pressure
- Antivenin medication, if the sting is from a box jellyfish
- Pain medicine
Other medical treatments
