Treatments and drugs

By Mayo Clinic Staff

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)
  • 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

Other circumstances also may require doctor-supervised treatment:

  • A rash or other skin reaction due to delayed hypersensitivity may be treated with oral antihistamines or corticosteroids.
  • A jellyfish sting occurring on or near an eye requires immediate medical care for pain control and a good eye flushing. You will likely be seen by a doctor specializing in eye care (ophthalmologist).
