Anaphylaxis

Using adrenaline to treat anaphylaxis

Adrenaline stimulates the heart and reverse the spasm in the blood vessels and the lung passages, reduces oedema and urticaria, thus countering the anaphylaxis. But this very potent agent can cause irregular heartbeat, heart failure, severe hypertension and tissue  necrosis if used inappropriately, although not when treating true anaphylaxis.
