Abstract
The UK resuscitation council advises that intramuscular adrenaline should be administered as soon as possible in patients with suspected anaphylaxis with signs of shock, airway swelling or breathing difficulty.
The dose of adrenaline for adults and children over the age of 12 years is 0.5 ml (500 μg) 1:1000.
Hydrocortisone and chlorphenamine are second-line agents.
