Similar to other box jellyfish stings, first aid consists of flushing the area with vinegar to neutralize the tentacle stinging apparatus. As no antivenom is available, treatment is largely supportive, with analgesia being the mainstay of management. Nitroglycerin, a common drug used for cardiac conditions, is utilised by medical personnel to minimise the risk of pulmonary edema and to reduce hypertension. Antihistamines may be of benefit for pain relief, but most cases require intravenous opioid analgesia. Fentanyl or morphine are usually chosen. Pethidine (meperidine, brand name Demerol in the US) should be avoided, as large doses are often required for pain relief and in this situation significant adverse effects from the pethidine metabolite norpethidine may occur. Magnesium sulfate (Epsom Salts) has been proposed as a treatment for<unk>  after being apparently successfully used in one case. Early evidence suggested a benefit; however, according to a later report, a series of three patients failed to show any improvement with magnesium; the author emphasized the experimental status of this treatment. Some preliminary laboratory experiments using the venom extracted from Malo maxima (the 'Broome<unk> ') on rat cardiovascular tissue in vitro has suggested that magnesium does in fact block many of the actions of this venom.
