Box jellyfish stings


Reactions to box jellyfish stings can be immediate or delayed by several days or even weeks. Complications may include the following.

Irukandji Syndrome

Some box jellyfish stings cause Irukandji syndrome, a group of symptoms that begin 20–30 minutes after the sting and progress over a few days.

 The syndrome is not typically fatal, but it can make you seriously ill, and some people do die from it.

Symptoms include:

  • Pain
  • Muscle cramping and spasms
  • Sweating
  • Shaking
  • Nausea and vomiting
  • Rapid heart rate
  • High blood pressure

In very serious cases, a person may experience cardiogenic shock or a pulmonary edema.

Irukandji syndrome often requires hospitalization, so if you have been stung by a jellyfish, pay close attention to symptoms that may arise sometime afterward.
