Rationale

Bites by sea snakes are extremely rare in Australia. The current stocking recommendation reflects a pragmatic approach to antivenom stocking.

Precautions

  • Hypersensitivity reactions may occur. Antivenom should be administered in a critical care area in anticipation of potential anaphylaxis.
  • Premedication with steroids/adrenaline is not recommended.
  • If a hypersensitivity reaction occurs, pause the infusion and treat along standard lines. Recommence the infusion once the reaction settles at a slower rate.
  • If the hypersensitivity reaction is severe, discuss the case with a clinical toxicologist.

Serum sickness may occur 4 to 14 days following the administration of antivenom. Symptoms include fever, rash, joint and muscle pain, headache, nausea and vomiting. Patients should be informed of the symptoms and present to their local doctor should they occur.
